Features/Benefits
Flexibility for every application
The zone controller is a single duct, fan
powered, variable air volume (VAV)
terminal control with a factoryintegrated controller and actuator.
The zone controller maintains precise
temperature control in the space by
operating the terminal fan and regulating the flow of conditioned air into the
space.
Buildings with diverse loading
conditions can be supported by controlling reheat (single duct only) or
supplemental heat. The zone controller
can support single position hot water,
modulating hot water, 2-stage electric,
or perimeter heat.
Carrier Linkage System
compatibility
When linked to a Carrier Linkage
System, the zone controller provides
numerous features and benefits such as
weighted average demand for system
operation, intelligent supply-air
temperature reset, set point averaging,
global set point schedule, and occu-
2
pancy scheduling. Duct static reset for
the air source is provided, based on
terminal requirements.
Additional control features
The zone controller provides additional
control features such as Occupied/
Unoccupied scheduling initialized via
the network. The zone controller offers
override invoked from a wall sensor
during unoccupied hours from 1 to
1440 minutes in 1-minute increments.
Optional Indoor Air Quality (IAQ) or
relative humidity monitoring and control are also available.
Simple actuator connection
The zone controller control assembly
contains an integral VAV actuator
assembly that is field mounted to the

SAFETY CONSIDERATIONS
SAFETY NOTE
Air-conditioning equipment will provide safe and reliable service when operated within design specifications.
The equipment should be operated and serviced only by
authorized personnel who have a thorough knowledge
of system operation, safety devices and emergency
procedures.
Good judgement should be used in applying any manufacturer’s instructions to avoid injury to personnel or damage to equipment and property.
Disconnect all power to the unit before performing maintenance or service. Unit may automatically start if power is
not disconnected. Electrical shock and personal injury
could result.
GENERAL
The 3V control system VVT bypass controller (33ZCBC-01)
is a system static pressure controller that operates to maintain the
desired system duct pressure based on the system pressure set
point. The VVT bypass controller is used with a system of VVT
zone controllers. Zone controllers maintain precise temperature
control in the space by regulating the flow of conditioned air into
the space and operating an optional terminal fan.
As part of the 3V control system, the bypass controller is
designed to communicate using a Carrier protocol with a
Linkage Coordinator zone controller. One Linkage Coordinator zone controller can coordinate up to 31 additional zone
controllers. The purpose of the Linkage Coordinator/zone
relationship is to provide an efficient data path for communication between the zone controllers, bypass controller, and
associated Carrier network air source. This arrangement makes
up the 3V control system.
A user interface is not required for everyday operation of
the bypass controller. A service person or building owner can
configure or operate the bypass controller through a Carrier
network user interface such as the System Pilot or Carrier
software.
INSTALLATION
General — The bypass controller is used to control the
bypass damper actuator in the 3V control system. The purpose
of the bypass damper is to account for fluctuations in the supply air pressure caused by the zone dampers modulating to satisfy individual set points. The bypass system allows a constant
volume HVAC (heating, ventilation and air conditioning) unit
to supply variable volumes of air to the building. The system
bypasses air from the supply side to the return side of the unit.
Determining the proper size for the bypass damper is critical for the operation of the VVT (variable volume/variable
temperature) system. If the damper selected is too large, it may
have to modulate more than necessary to react to system pressure changes. The ability of the system to stay within a pressure
range is compromised. When the damper is undersized, the
capability of the damper to control the pressure may be compromised due to the inability to bypass enough air volume. An
undersized damper also creates higher airflow velocities which
add to the noise generated by the system.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

This book will discuss installation and wiring of the bypass
controller and bypass actuator. The bypass damper and duct
system should already be correctly sized and installed. The bypass actuator should be sized to match the bypass damper.
Carrier provides system software that can be used to design the
system and choose the correct dampers and actuators based on
the application.
6.
Bypass Controller Hardware — The bypass controller consists of the following hardware:
• control module
• plastic enclosure with integrated actuator
• one no. 8 x 3/4-in. self-drilling sheet metal screw
Figure 1 shows the bypass controller physical details.
7.
Field-Supplied Hardware — Each bypass controller
requires the following field-supplied components to complete
its installation:
• damper
• damper actuator (if high-torque actuator is required)
• transformer — 24 vac, 40 va (standard applications)
• duct temperature sensor (33ZCSENDAT) with grommet
(to secure DAT sensor to duct)
DUCT TEMPERATURE SENSOR (DAT) — The bypass
controller must be connected to a field-supplied duct temperature sensor (part number 33ZCSENDAT) to monitor the temperature of the air delivered by the air source.
8.
Mount Bypass Controller
LOCATION — The bypass controller should be located on or
near the bypass damper in a ceiling area where accessible.
When an external high-torque actuator is used, the bypass
controller is mounted on the shaft of the damper. Select a
location which will be safe from water damage and allow
sufficient access for service and wiring. For service access,
there should be at least 6 in. of clearance between the front of
the bypass controller and adjacent surfaces. Refer to Fig. 1-3.
MOUNTING — Perform the following steps to mount the
bypass controller:
1. Visually inspect the damper and determine the direction in which the damper shaft moves to open the
damper — clockwise (CW) or counterclockwise
(CCW).
If the damper rotates CCW to open, it does not require
any configuration changes.
If the damper rotates CW to open, then the damper
actuator logic must be reversed. This is done in the
software when performing system start-up and damper
calibration test. Do not attempt to change damper rotation by changing wiring. This will upset the damper
position feedback potentiometer readings.
2. Rotate the damper shaft to the fully closed position.
3. Press the release button on the actuator and rotate the
clamp in the same direction that was required to close
the damper in Step 2.
4. Press the actuator release button and rotate the actuator
back one-position of graduation. Release the button
and lock the actuator in this position.
5. Mount the bypass controller to the terminal by sliding
the damper shaft through the actuator clamp assembly.
See Fig. 2 for details. Remove the controller wiring
9.
access cover. Secure the controller by installing the
screw provided through the grommet in the antirotation slot. Detach the grommet from the slot so it
can slide from side to side. Be sure the floating grommet is in the center of the slot. FAILURE TO
CENTER THE GROMMET MAY CAUSE THE
ACTUATOR TO STICK OR BIND.
Tighten the actuator clamp assembly to the damper
shaft. Secure by tightening the two 8-mm nuts.
If the damper has less than 90 degrees of travel
between the fully open and fully closed positions, then
a mechanical stop must be set on the actuator. The
mechanical stop prevents the damper from opening
past the maximum damper position. To set the
mechanical stop, perform the following procedure:
a. Press the actuator release button and rotate the
damper to the fully open position.
b. Using a No. 1 Phillips screwdriver, loosen the
appropriate stop clamp screw and move the stop
clamp so that it contacts the edge of the cam on
the actuator.
c. Secure the stop clamp in this position by tightening the screw.
Verify that the damper opens and closes. Press the
actuator release button and rotate the damper. Verify
that the damper does not rotate past the fully open
position. Release the button and lock the damper in the
fully open position.
Replace wiring access cover.
Connect the Power Transformer — An individual,
field-supplied, 24-vac power transformer is required for each
bypass controller. Transformers must be UL (Underwriters’
Laboratories) Class 2 rated. Standard applications require a
24 vac transformer, rated at 40 va minimum. All transformer
secondaries are required to be grounded. Use only stranded
copper conductors for all wiring to the bypass controller.
Wiring connections must be made in accordance with NEC
(National Electrical Code) and local codes. Ground one side of
the transformer secondary at the transformer location. Connect
the grounded side of the transformer to J1-2. Connect the live
side of the transformer secondary to J1-1. Connect an 18-gage,
green ground wire from terminal J1-3 to the metal chassis of
the unit.
The power supply is 24 vac ± 10% at 40 va (50/60 Hz).
For bypass controllers, the power requirement sizing allows
for the bypass actuator. The bypass damper actuator is limited
to 20 va.
NOTE: Do not run sensor or communication wiring in the
same conduit with line-voltage wiring.
Perform the following steps to connect the power
transformer:
1. Install the field-supplied transformer in an electrical
enclosure that conforms to NEC and local codes.
2. Connect 24 vac from the transformer as shown in the
applicable wiring diagram (Fig. 4). Be sure to observe
polarity when connecting the transformer power. The
grounded terminal must be connected to the transformer
ground terminal as shown.

Install Duct Temperature Sensor — The duct temperature sensor is required. The duct temperature sensor must
be installed in the supply air duct. The 33ZCSENDAT is the
recommended sensor. See Fig. 5 for sensor details.
For bypass systems, the duct temperature sensor should be
moved to a location which will provide the best sensing of the
supply-air temperature during heating and cooling.
For bypass systems using a ducted supply, the duct temperature sensor should be located in the main supply duct
downstream of the discharge of the air source and before the
bypass damper to allow good mixing of the supply airstream.
The 33ZCSENDAT duct sensor is a small epoxy sensor that
is 11/4-in. long. A grommet is provided for filling the hole
around the sensor cable after the sensor is located in the duct.
See Fig. 3 and 6 for mounting location.
Install Pressure Tubing — The static pressure pick up
should be located in the main supply duct before the first
branching of ductwork. Run the tubing from the bypass controller to the installation location. For stable airflow measurement, the recommended minimum length of tubing is 2 ft.
Connect the tubing to the high side of the pressure sensor
marked P1. Make sure the low side of the pressure sensor (P2)
is open to the atmosphere. See Fig. 3.

Install Field-Supplied Actuators — Follow the damper manufacturers recommended installation instructions with
the following recommendations.
Belimo Multi-Function technology actuators may be ordered
direct from Belimo. The following accessory actuators may be
used instead of the integrated actuator:
• NM24-MFT US P-30002 — 70 in.-lb actuators with
floating point control and 0 to 10 vdc feedback.
• AM24-MFT US P-30002 — 160 in.-lb actuators with
floating point control and 0 to 10 vdc feedback.
The following actuators may be used as linked actuators.
Up to four actuators may be linked to the main actuator:
• LM24-MFT US P-10002 — 35 in.-lb actuators with 0 to
10 vdc control and 0 to 10 vdc feedback.
• NM24-MFT US P-10002 — 70 in.-lb actuators with 0 to
10 vdc control and 0 to 10 vdc feedback.
• AM24-MFT US P-10002 — 160 in.-lb actuators with 0
to 10 vdc control and 0 to 10 vdc feedback.
FLOATING POINT HIGH-TORQUE ACTUATORS —
The field-supplied floating point high-torque actuators are
multi-function technology actuators intended for applications
where higher torque is needed for bypass operation. These
actuators would replace the integrated actuator on the bypass
controller. The actuators have three wires for power and
control and one 0-10VDC feedback wire to send a signal to the
bypass controller and any linked actuators. The three control
wires are 1(BLK), 2(RED), and 3(WHT). The 1(BLK) and
2 (RED) wires provide power to the actuator. These should be
wired to the same power source as the bypass controller
making sure wire 2 (RED) connects to J1-1 on the power plug
of the Bypass controller and wire 1 (BLK) connects to J5-2 the
common of the Bypass Controller power. See Fig. 7 and 8 for
wiring.
Polarity of the actuator and bypass controller power must be
the same for proper operation and to prevent damage to the
devices. A 1N4004 or 1N4007 diode must be placed across the
CCW and CW terminals of the bypass controller. The end of
the diode with the silver band tip (positive end) should be
placed in the CCW terminal along with Wire 3(WHT). The
other end of the diode should be placed in the CW terminal
with the actuator switch in the CW or default position. This
will make the damper rotate CCW when the CCW terminal is
energized and CW when the CW terminal is energized. For
reverse rotation the actuator switch may be changed to the
CCW position.
LINKED ACTUATORS — Field-supplied linked actuators
may be used to link to the bypass controller actuator. Install the
actuators per the manufacturer’s directions. Provide power for
the linked actuators by wiring 24 vac to the 1(BLK) and 2
(RED) wires. Maintain polarity if more than one actuator is
powered by the same power supply. Make sure the direction
rotation switches on the linked actuators are set to CW. Wire
the wire 3 (WHT) of the linked actuator(s) to the wire 5 (GRN)
of the controlling actuator. The linked actuator will then track
to the same damper position as the controlling actuator. See
Fig. 8-10 for wiring.
Linked actuators may be used to control off the integrated
actuator of the bypass controller actuator. Install the actuators
per the manufacturer’s directions. Provide power for the linked
actuators by wiring 24 vac to the 1 (BLK) and 2 (RED) wires.
Maintain polarity if more than one actuator is powered by the
same power supply. Make sure the direction rotation switches
on the linked actuators are set to CW. Connect wire 3 (WHT)
of the linked actuator to J4-7(DMPPOS).
Damper Stops — For clockwise closed installations the
damper stop on the right side of the damper shaft is left at the
full clockwise position. The stop on the left side of the shaft
must be moved to stop the actuator at the full open position for
the damper. For example the Carrier round dampers rotate
45 degrees. Slide the left stop up to the 45 degree mark. Press
the actuator release button and rotate the damper CCW all the
way to the stop. The damper blade indicator should indicate
the damper is full open. Wire 5 (white) should be wired to
J4-7(DMPPOS). See Fig. 2.
NOTE: The rotation switch should be in the CW position for
correct feedback for this application. Reverse the rotation by
configuring the bypass controller for clockwise open and do
not change the switch from the CW position.
Connect the Carrier Network Communication Bus — The bypass controllers connect to the bus in a
daisy chain arrangement. The bypass controller may be installed on a primary bus or on a secondary bus from the primary bus. Connecting to a secondary bus is recommended.
At any baud (9600, 19200, 38400 baud), the number of controllers is limited to 239 zones maximum. Bus length may not
exceed 4000 ft, with no more than 60 total devices on any
1000-ft section. Optically isolated RS-485 repeaters are required every 1000 ft.

COMMUNICATION BUS WIRE SPECIFICATIONS —
The communication bus wiring is field-supplied and fieldinstalled. It consists of shielded three-conductor cable with
drain (ground) wire. The cable selected must be identical to the
Carrier Network communication bus wire used for the entire
network. See Table 3 for recommended cable.
When connecting the communication bus cable, a color
code system for the entire network is recommended to
simplify installation and checkout. See Table 4 for the
recommended color code.

3. Connect the other end of the communication bus cable
to the terminal block labeled CCN in the bypass
controller. Following the color code in Table 4,
connect the Red (+) wire to Terminal 1. Connect the
White (ground) wire to Terminal 2. Connect the Black
(–) wire to Terminal 3.
4. Connect additional devices in a daisy chain fashion,
following the color coded wiring scheme in Table 4.
Refer to Fig. 11.
NOTE: The communication bus drain wires (shield) must
be tied together at each device. If the communication bus is
entirely within one building, the resulting continuous shield
must be connected to ground at only one single point. If the
communication bus cable exits from one building and enters
another building, connect the shields to ground at a lightning suppressor in each building where the cable enters or
exits (one point only).
NOTE: Conductors and drain wire must be at least 20 AWG
(American Wire Gage), stranded, and tinned copper. Individual conductors must be insulated with PVC, PVC/nylon, vinyl, Teflon, or
polyethylene. An aluminum/polyester 100% foil shield and an outer
jacket of PVC, PVC/nylon, chrome vinyl, or Teflon with a minimum
operating temperature range of –20 C to 60 C is required.
CONNECTION TO THE COMMUNICATION BUS
1. Strip the ends of the red, white, and black conductors of
the communication bus cable.
2. Connect one end of the communication bus cable to
the bridge communication port labeled COMM2 (if
connecting on a secondary bus).

START-UP
CONFIGURATION
Use the Carrier network communication software to start up
and configure the bypass coil controller.
All set-up and set point configurations are factory-set and
field-adjustable.
Changes can be made using the System Pilot or Carrier
software. During start-up, the System Pilot or Carrier software
can also be used to verify communication with the bypass
controller.
For specific operating instructions, refer to the literature
provided with the System Pilot or Carrier software.
The following sections describe the computer configuration
screens which are used to configure the bypass controller. The
screens shown may be displayed differently when using different Carrier software.
Status Display Table — The status display table is used
to show status of different functions of the bypass controller.
The values displayed in this table are read-only values. See
Table 5.
SYSTEM MODE — The System Mode variable displays the
Linkage Coordinator zone controller’s system mode as the bypass controller’s system mode except when the bypass controller is in its commissioning mode or the network communication fails. In bypass commissioning mode, the system mode
will display BPCOMMIS to indicate the bypass controller is in
its own commissioning mode. If the network communication
between the bypass controller and the linkage coordinator fails,
the system mode will display LOCAL.

Perform System Checkout — To check out the system, perform the following:
1. Apply 24 vac power to the bypass controller.
2. Using the System Pilot, upload the controller from
address 0,141 (default address). The address may be set at
this time. The address should be set to 1 higher than the
monitor or the linkage coordinator.
3. Access the bypass controller commissioning and maintenance tables.
4. If the terminal damper closes in the clockwise direction,
then no adjustment is required. If the terminal damper
opens in the clockwise direction, set the CW Rotation
point to OPEN.
5. Force the Bypass Commis point to Enable.
6. Force the Damper Calibration point to Enable. The automatic bypass damper calibration process will begin. The
bypass controller will verify that the air source fan is off.
Communication with the linkage coordinator is required.
Make sure the linkage coordinator and the Bypass
Controller are addressed correctly.
NOTE: If the Bypass Controller is in local mode (stand
alone), the user must make sure the duct static pressure is
0 to enable damper calibration.
If the fan is turned on, the Damper Calibration process
will be aborted. The bypass damper will travel to its minimum and maximum positions. The damper positions
will be saved and used by the bypass controller. When the
damper calibration process is complete, the bypass controller will automatically return the point to Disable.
7. Force the Zero Pressure Sensor Cal point to Enable. The
bypass controller verify that the air source fan is off. If the
fan is turned on, the Zero Pressure Sensor Calibration
process will be aborted. The bypass controller will automatically calibrate the zero value of the pressure sensor.
When the calibration process is complete, the bypass controller will automatically return the point to Disable.
8. Set up all zone controllers and perform system commissioning at the linkage coordinator before adjusting the
System Pressure Set Point.
9. Adjust the System Pressure Set Point by forcing the point
to the desired value. The bypass controller will write the
forced value to the set point table and will begin to control to the new bypass pressure set point.
10. Read the airflow with a measuring device. If the reading
varies from the screen value, force the value to the measured value. Once the pressure sensor is forced, the controller will automatically calibrate the pressure sensor (as long
as the bypass damper is not >95% open). Repeat as needed.

TABLE — The bypass controller configuration table contains
decisions used to configure the damper modulation and the
LAT (leaving air temperature) protection decisions. The bypass
controller can also be configured as a broadcast acknowledger.
See Table 10.
Damper Control Deadband — This decision is used to configure a deadband for bypass damper position control. This algorithm operates based on the pressure sensor input to achieve the
desired set point. In the algorithm, an error signal is defined as
the difference between the system pressure set point and the
pressure sensor input. The deadband is multiplied by a fixed
value of 0.05 to adjust the reaction of the damper algorithm.
The size of the deadband will correspond to the gain of the
loop. The smaller the deadband, the higher the gain and the
faster the loop will react. The larger the deadband, the lower
the gain and the slower the loop will react.
NOTE: If the Damper Control Deadband value is set too low,
excessive actuator movement and wear may occur.

bypass damper position is greater than this configured limit and
the duct temperature meets required conditions, an alarm will
be generated.
During the heating mode if the duct temperature is greater
than the Heating LAT Limit plus 10° F for more than 2 minutes
then a Low Heating Airflow Pressure Alarm will be generated.
During the cooling mode if the duct temperature is
lower than the Cooling LAT Limit minus 2° F for more than
2 minutes then a Low Cooling Airflow Pressure Alarm will be
generated.
The damper position configured in this decision is also used
when the associated master zone controller has not determined

OPERATION
the feedback resistance value meets the Damper Closed
Criteria in Table 15, the bypass controller will store the value in
non-volatile memory as the resistance at fully closed. The
bypass controller will then position the damper fully open.
When the feedback resistance value stops changing, the bypass
controller reads the value and if the feedback resistance value
meets the Damper Open Criteria in Table 15, the bypass
controller stores the value as the resistance at fully open. The
bypass controller will use the following formula to determine
damper position:
For damper rotation configured as Open:
Damper Position (% open) = ((Feedback Resistance –
Resistance at Full Closed)/((Resistance at Full Open) –
(Resistance at Full Closed))) * 100.
For damper rotation configured as Closed:
Damper Position (% open) = 100 – ((Feedback Resistance –
Resistance at Full Closed)/((Resistance at Full Open) –
(Resistance at Full Closed))) * 100.
System Pressure Operation
NORMAL OPERATION — The bypass controller will modulate its damper to maintain the proper system static pressure
set point. The bypass controller does this by comparing its
pressure sensor input reading to the configured system static
pressure set point and determining the error (sensor reading —
set point). The bypass controller then compares the calculated
error to the configured deadband value. If the error is greater
than 1/4 of the deadband value (configured deadband times a
constant of 0.05), then the bypass controller commands the
damper to open or close (depending on the positive or negative
value of the error). If the error is less than 1/4 of the deadband
value, the bypass controller holds the damper position. If the
pressure sensor fails, the bypass controller will move the
damper to the configured Pressure Sensor Error Damper
Position. See Fig. 12 for an operation flow chart.
LEAVING AIR TEMPERATURE (LAT) MODE — The bypass controller will provide LAT protection by controlling the
system pressure based on its duct temperature. If the duct
temperature goes above the configured heating LAT limit or
below the cooling LAT limit, the bypass controller will
increase the pressure set point by the configured LAT Pressure
Delta value. This will cause the amount of bypassed air going
back to the air source to be reduced. If the LAT Pressure Delta
decision is configured for zero, the LAT protection function
will be disabled. The bypass controller will control to the
normal system pressure set point again at the end of the current
heating or cooling cycle, or when its duct temperature sensor
reads greater than the Cooling LAT limit plus five degrees or
less than the Heating LAT limit minus ten degrees. This
temperature swing would indicate that the air source cycled the
heating or cooling as part of its LAT protection, or because the
system conditions are close to satisfying the mode.
NOTE: Bypass LAT protection is disabled during Bypass
Commissioning mode, or if the duct temperature sensor fails.

If an invalid resistance value is read, the bypass controller
will not store or use the value, and will issue a Damper
Calibration Alarm. If the bypass controller loses communication with its associated Linkage Coordinator, the damper
calibration process will be terminated. When the damper
calibration is completed, the bypass controller will signal the
Linkage Coordinator to return the fan to normal operation.
PRESSURE TRANSDUCER ZERO CALIBRATION —
Pressure transducer calibration will occur under two conditions
if it is not operating in stand-alone mode. The first condition is
when it is forced by the user in the BPCOMMIS maintenance
table to perform this operation. The second condition is when
the system goes in to the unoccupied mode for at least 5 minutes
or 168 hours (7 days) since the last calibration, whichever
comes first. If the bypass controller is not operating in
stand-alone mode, it will verify the system fan status with its
associated Linkage Coordinator. If the fan is on, the bypass
controller will send a high priority request to its Linkage
Coordinator to turn the fan off. If the fan is already off, the
bypass controller will send the same priority request to ensure
that the fan stays off during the calibration procedure. If for
some reason the bypass controller loses communication with its
Linkage Coordinator for more the 60 minutes or the procedure
takes longer the 60 minutes, the Linkage Coordinator will return
the fan and system to normal operation and the bypass controller
will terminate the calibration procedure and return to normal
operation.
NOTE: If the bypass is in stand-alone mode (not communicating with a Linkage Controller), the user must ensure the
pressure reading is zero before performing calibration.
Bypass Controller Calibration — The bypass controller allows calibration of the damper and pressure sensor
from the Bypass Commissioning Maintenance screen. Refer to
the System Check-Out section for the step-by-step procedure.
DAMPER CALIBRATION — If the bypass controller is not
operating in stand-alone mode, it will verify the system fan
status with its associated Linkage Controller. If the fan is on,
the bypass will request its Linkage Controller to turn the fan
off.
NOTE: If the bypass controller is in stand-alone mode (not
communicating with a Linkage Coordinator) the user must
ensure the pressure reading is zero before performing
calibration. The bypass controller will not be allowed to enter
calibration mode if the fan is on.
In either case, the bypass will check to ensure the fan is off
by reading its pressure sensor and damper position. If the
pressure reading is less than 10% of the static pressure set point
and the bypass damper position is less than 25% of the
resistance of the feedback potentiometer for greater than
60 seconds, then the bypass controller assumes the fan is off.
When the fan is off, the bypass controller will drive its damper
to the fully closed position. The bypass controller will read the
value of the actuator’s feedback potentiometer until the value
stops changing. This indicates the damper is fully closed. If
18
the voltage reads within the range of 1.0 vdc ± 0.1 volt, it
calculates the offset voltage based on the difference between
the output voltage reading and the nominal zero pressure
reading of 1.0 vdc. This value is then stored in non-volatile
memory. If the voltage reading is outside of the tolerance
range, the bypass controller will display “Alarm” in the
commissioning screen. The screen will display “Alarm” until a
successful calibration of the pressure sensor is performed.
When the calibration is completed, the bypass controller will
signal the Linkage Coordinator to return the fan to normal
operation.
In either case, the bypass controller will check to ensure the
fan is off by reading its pressure sensor and damper position. If
the pressure reading is less than 10% of the static pressure set
point and the bypass damper position is less than 25% of the
resistance of the feedback potentiometer for greater than
60 seconds, then the bypass controller assumes the fan is off.
When the fan is off, the bypass controller will drive its damper
to the fully open position. If an invalid feedback resistance
value is detected, the bypass controller will terminate the
calibration. Once at the fully open damper position, the bypass
controller will read the output voltage of the pressure sensor. If

GENERAL
Carrier’s network software can be connected to the system
at the SPT sensor if Carrier network communication wiring is
run to the SPT sensor. The network software can be used to
adjust set points, set operating parameters, and fully configure
the zone controller or any device on the system.
The zone controller is a single duct, fan powered, Variable
Volume and Temperature (VVT®) terminal control with a
factory-integrated controller and actuator. The VVT zone controller maintains precise temperature control in the space
by operating the terminal fan and regulating the flow of
conditioned air into the space. Buildings with diverse loading
conditions can be supported by controlling equipment heating
and cooling sources or supplemental heat.
The VVT zone controller (33ZCVVTZC-01) provides
dedicated control functions for single duct terminals with
modulating heat, up to 3 stages of ducted heat, or combination
baseboard and ducted heat. A relay board (33ZCOPTBRD-01)
is required for heat or fan terminals.
Carrier’s 3V™ control system provides optimized equipment and component control through airside linkage. Linkage
refers to the process through which data is exchanged between
the air terminals and the air source that provides the supply air
to those terminals. The process “links” the terminals and the air
source to form a coordinated system. Linkage allows the air
source to operate efficiently and reliably while responding to
and satisfying changing conditions in the zones. Linkage also
allows the terminals to respond properly to changes in the air
source. A VVT zone controller configured as the Linkage
Coordinator manages the flow of data between the air source
and the VVT system zones.
Rooftop units, air handlers, fan coils, and water source heat
pumps feature product integrated or factory-installed controls
that are directly compatible with the 3V control system. The
rooftop units, air handlers, fan coils, and water source heat
pumps do not require any special hardware to be compatible
with the Carrier linkage system. Consult your local Carrier
representative for the complete list of compatible air source
controllers. Figure 1 shows an example of a Carrier linkage
system.
The VVT zone controllers are available factory-mounted to
Carrier’s round and rectangular dampers. Round dampers are
available in 6, 8, 10, 12, 14, and 16-in. sizes. Rectangular
dampers are available in 8x10, 8x14, 8x18, and 8x24-in. sizes.
All damper assemblies are equipped with an integrated duct
temperature sensor.
Zone Controller Hardware — The zone controller
consists of the following hardware:
• terminal control module
• torque-limiting integrated damper actuator
• plastic enclosure
• one no. 8 x 1/2-in. self-drilling sheet metal screw (to prevent zone controller rotation)
Figure 2 shows the zone controller physical details.
Field-Supplied Hardware — Each zone controller requires the following field-supplied components to complete its
installation:
• air terminal unit (unless factory installed — when purchased as factory-installed option an SAT [supply-air
temperature] sensor is provided upstream of the damper
blade)
• round or rectangular mounting bracket (for retrofit
applications)
• space temperature sensor
• transformer — 24 vac, 40 va
• two no. 10 x 1/2-in. sheet metal screws (to secure SAT
sensor to duct, if required)
• two no. 6-32 x 5/8-in. screws (to mount SPT [space temperature] sensor base to electrical box)
• contactors (if required for fan or electric heat)
• supply air temperature sensor (required for terminal with
ducted heat)
• option board 33ZCOPTBRD-01 (required for auxiliary
heat or fan terminals)
• indoor air quality sensor (if required)
• relative humidity sensor (if required)
• one SPST (single pole, single throw) relay
• valve and actuator for hot water heat (if required)
• wire
• bushings (required when mounting SAT sensor in a duct

INSTALLATION
General — The VVT zone controller is a microprocessorbased direct digital control (DDC) controller that can be purchased or installed on variable volume and temperature (VVT)
air terminals. It can be retrofitted on units manufactured by
Carrier or other manufacturers to provide pressure dependent
VVT control.
Each zone controller has the ability to function as a linkage
coordinator for systems with up to 32 zones. As a linkage
coordinator, a zone controller will retrieve and provide system
information to the rooftop or air-handling equipment and other
zone controllers. A zone controller can function as a stand
alone device by installing a duct air sensor.
The zone controller is connected to a wall-mounted, fieldsupplied, space temperature sensor (SPT) in order to monitor
zone temperature changes and satisfy zone demand.
On stand-alone applications or applications with ducted or
modulating heat, the zone controller must be connected to a
field-supplied supply air temperature (SAT) sensor to monitor
the temperature of the air delivered by the air terminal. A
System Pilot can be used to adjust set points, set operating
parameters, and fully configure the zone controller or any
device on the system. A System Pilot can also provide local
space temperature, set point adjust, time broadcast, and schedule adjustment for a single dedicated or remote device.
The System Pilot is a user interface to the Zone Controller
with a full complement of zone display features that can be
used to configure and operate the Zone Controller. It has an
SPT sensor and can transmit its value to the Zone Controller.
The System Pilot communicates to the Zone Controller
through the Zone Controller’s dedicated Comm2 port or over
the main communication bus through Comm1.
OPTION BOARD — The option board (33ZCOPTBRD-01)
is required for use of auxiliary heat and fan control functions.
The Option Board is field installed and provides four triac
discrete outputs, three for supplemental heat and one for the fan
output.
PRIMARY AIR TEMPERATURE SENSOR — A fieldsupplied, primary air temperature (PAT) sensor (part number
33ZCSENPAT) is used on a zone controller which is functioning as a Linkage Coordinator for a non Carrier Network/
Linkage compatible air source.

SUPPLY AIR TEMPERATURE (SAT) SENSOR — The
33ZCSENSAT supply air temperature sensor is required for
reheat applications or stand-alone operation. The sensor has an
operating range of –40 to 245 F (–40 to 118 C) and includes a
6-in. stainless steel probe and cable.
DUCT AIR TEMPERATURE SENSOR — The 33ZCSENDAT
Duct Air Temperature Sensor is required for cooling only applications on non-33CS or non-Carrier dampers. The sensor is used
for supply air monitoring. The sensor has an operating range of
–40 to 245 F (–40 to 118 C) and includes a mounting grommet
and 75-in. cable.
RELATIVE HUMIDITY SENSOR — The 33AMSENRHS000
relative humidity sensor is required for zone humidity control
(dehumidification) when in a linked system with a rooftop unit
equipped with a dehumidification device. Otherwise, the RH
sensor is used for monitoring only.
NOTE: The relative humidity sensor and CO2 sensor cannot be
used on the same zone controller.
INDOOR AIR QUALITY (CO2) SENSOR — An indoor air
quality sensor is required for optional demand control
ventilation. The 33ZCSENCO2 CO2 sensor is an indoor, wall
mounted sensor with an LED display. The 33ZCT55CO2 and
33ZCT56CO2 CO2 sensors are indoor, wall-mounted sensors
without display.
NOTE: The relative humidity sensor and CO2 sensor cannot be
used on the same zone controller.
should be at least 12 in. of clearance between the front of the
zone controller and adjacent surfaces. Refer to Fig. 3.
MOUNTING — Perform the following steps to mount the
zone controller:
1. When retrofitting a zone controller on an existing
damper, prior to installing the zone controller, remove all
existing hardware.
2. Round or rectangular damper brackets may be attached to
the damper to provide a clearance for the damper bearing
when the zone controller is installed on older style VVT®
dampers. The zone controller is used to determine the
location of the bracket. Attach the bracket to the zone controller using a single screw through the anti-rotation tab.
3. Visually inspect the damper and determine the direction
in which the damper shaft moves to open the damper —
clockwise (CW) or counterclockwise (CCW). Refer to
Fig. 4.
If the damper rotates CCW to open, it does not require
any configuration changes.
If the damper rotates CW to open, then the damper
actuator logic must be reversed. This is done in the
software when performing system start-up and damper
calibration test. Do not attempt to change damper rotation
by changing wiring. This will upset the damper position
feedback potentiometer readings.
4. Rotate the damper shaft to the fully closed position. Note
direction of rotation.
5. Press the release button on the actuator and rotate the
clamp in the same direction that was required to close the
damper in Step 4.
6. Press the release button on the actuator and rotate the
actuator back one position graduation. Release the button
and lock the actuator in this position.
Mount Zone Controller (Retrofit Applications) — The zone controller is factory-mounted on Carrier
round and rectangular dampers. When retrofitting a zone
controller on an existing damper, perform the following
procedures.
LOCATION — The zone controller must be mounted on the
air terminal’s damper actuator shaft. For service access, there

9. If the damper has less than 90 degrees of travel between
the fully open and fully closed positions, then a mechanical stop must be set on the actuator. The mechanical stop
prevents the damper from opening past the maximum
damper position. To set the mechanical stop, perform the
following procedure:
a. Press the actuator release button and rotate the
damper to the fully open position.
b. Using a Phillips screwdriver, loosen the appropriate stop clamp screw.
c. Move the stop clamp screw so that it contacts the
edge of the cam on the actuator. Secure the stop
clamp screw in this position by tightening the
screw.
10. Verify that the damper opens and closes. Press the actuator release button and rotate the damper. Verify that the
damper does not rotate past the fully open position.
Release the button and lock the damper in the fully open
position.
NOTE: The actuator must rotate to the end of the actuator
range in the fully closed position. For actuators with less than
90 degrees of travel, the opposite stop must be moved so the
actuator travels to mid-range when fully open. Damper calibration will fail if stops on actuator are not set correctly.

Connect the Power Transformer — An individual,
field-supplied, 24-vac power transformer is recommended
for each zone controller. If multiple zone controllers are
powered from one power transformer (100 va maximum for
UL [Underwriters’ Laboratories] Class 2 conformance),
maintain polarity on the power input terminals. All transformer
secondaries are required to be grounded. Use only stranded
copper conductors for all wiring to the zone controller. Wiring
connections must be made in accordance with NEC (National
Electrical Code) and local codes. Ground the transformer at the
transformer location. Provide an 18-gage, green, chassis
ground wire at the terminal.
The power supply is 24 vac ± 10% at 40 va (50/60 Hz).
For VVT® zone controllers, the power requirement sizing
allows for accessory water valves and for electric heat contactor(s). Water valves are limited to 15 va on both two-position
and modulating hot water. The electric heat contactor(s) are
limited to 10 va (holding) each.
NOTE: If a water valve or electric heat contactor exceeds these
limits, or external contactors are required for electric heat, then
it is recommended a 60 va transformer be used. The maximum
rating for any output is 20 va.
NOTE: Do not run sensor or communication wiring in the
same conduit with line-voltage wiring.
NOTE: A conduit cover is provided and integrated with the
zone controller.
Perform the following steps to connect the power
transformer:
1. Install the field-supplied transformer in an electrical
enclosure that conforms to NEC and local codes.
2. Connect 24 vac from the transformer as shown in the
applicable wiring diagram (Fig. 5-13).

7. Mount the zone controller to the terminal by sliding the
damper shaft through the actuator clamp assembly.
Secure the zone controller to the duct by installing the
screw provided through the grommet in the anti-rotation
tab or by attaching the mounting bracket to the damper.
Be sure the floating grommet is in the center of the slot.
Failure to center the grommet may cause the actuator to
stick or bind.
8. Tighten the actuator clamp assembly to the damper shaft.
Secure by tightening the two 10-mm nuts.

Install Sensors
3. Connect the sensor cable as follows:
a. Connect one wire from the cable (RED) to the SPT
terminal on the controller. Connect the other end of
the wire to the left terminal on the SEN terminal
block of the sensor.
b. Connect another wire from the cable (BLACK) to
the GND terminal on the controller. Connect the
other end of the wire to the remaining open terminal on the SEN terminal block.
SPACE TEMPERATURE SENSOR INSTALLATION —
A space temperature sensor must be installed for each zone
controller. There are two types of SPT sensors available from
Carrier: the 33ZCT55SPT space temperature sensor with timed
override button and the 33ZCT56SPT space temperature sensor with timed override button and set point adjustment. See
Fig. 14.
The space temperature sensor is used to measure the
building interior temperature and should be located on an
interior building wall. The sensor wall plate accommodates
the NEMA standard 2 x 4 junction box. The sensor can be
mounted directly on the wall surface if acceptable by local
codes.
Do not mount the sensor in drafty locations such as near air
conditioning or heating ducts, over heat sources such as
baseboard heaters, radiators, or directly above wall mounted
lighting dimmers. Do not mount the sensor near a window
which may be opened, near a wall corner, or a door. Sensors
mounted in these areas will have inaccurate and erratic sensor
readings.
The sensor should be mounted approximately 5 ft from the
floor, in an area representing the average temperature in the
space. Allow at least 4 ft between the sensor and any corner
and mount the sensor at least 2 ft from an open doorway.
Install the sensor as follows (see Fig. 15):
1. Locate the two Allen type screws at the bottom of the
sensor.
2. Turn the two screws clockwise to release the cover from
the sensor wall mounting plate.
3. Lift the cover from the bottom and then release it from
the top fasteners.
4. Feed the wires from the electrical box through the
opening in the center of the sensor mounting plate.
5. Using two no. 6-32 x 1 mounting screws (provided with
the sensor), secure the sensor to the electrical box.
6. Use 20 gage wire to connect the sensor to the controller.
The wire is suitable for distances of up to 500 ft. Use a
three-conductor shielded cable for the sensor and set
point adjustment connections. The standard Carrier
Network communication cable may be used. If the set
point adjustment (slidebar) is not required, then an
unshielded, 18 or 20 gage, two-conductor, twisted pair
cable may be used.
The Carrier Network service jack requires a separate,
shielded communication cable. Always use separate
cables for communication and sensor wiring. (Refer to
Fig. 16 for wire terminations.)
7. Replace the cover by inserting the cover at the top of the
mounting plate first, then swing the cover down over the
lower portion. Rotate the two Allen head screws counterclockwise until the cover is secured to the mounting plate
and locked in position.
8. For more sensor information, see Table 1 for thermistor

PRIMARY AIR TEMPERATURE SENSOR INSTALLATION — A primary air temperature (PAT) sensor is used on a
zone controller which is functioning as a Linkage Coordinator
for a non Carrier Network/Linkage compatible air source. The
part number is 33ZCSENPAT. See Fig. 19.
When used on a zone controller, try to select a zone controller which will allow installation of the PAT sensor in the main
trunk, as close to the air source as possible. See Fig. 20.
DUCT TEMPERATURE SENSOR (33ZCSENDAT)
INSTALLATION — The 33ZCSENDAT Duct Air Temperature Sensor is required for cooling only applications on nonCarrier dampers. The sensor is used for supply air monitoring.
The sensor has an operating range of –40 to 245 F (–40 to
118 C) and includes a mounting grommet and 75-in. cable. The
duct temperature sensor must be installed in the supply air duct.
See Fig. 21 for sensor details.
The duct temperature sensor should be moved to a location
which will provide the best sensing of the supply-air temperature during heating and cooling.
For systems using a ducted supply, the duct temperature
sensor should be located in the supply duct downstream of the
discharge of the air source and before the bypass damper to
allow good mixing of the supply airstream.
The 33ZCSENDAT duct sensor is a small epoxy sensor that
is 11/4-in. long. A grommet is provided for filling the hole
around the sensor cable after the sensor is located in the duct.
See Fig. 22 for mounting location.

2. Push sensor through hole in the supply duct. Snap the
grommet into the hole until it is secure. Pull on the leads
of the duct sensor until the sensor is snug against the
grommet.
3. Connect the sensor leads to the bypass controller’s terminal board at the terminals labeled SAT and GND. See
Fig. 5-13 for wiring. If extending cable length beyond
8 ft, use plenum rated, 20 AWG (American Wire Gage),
twisted pair wire. Sensor wiring does not have polarity.
Either lead can be wired to either terminal.
4. Neatly bundle and secure excess wire.
5. Using electrical tape, insulate any exposed lead to prevent
shorting.
6. Connect shield to earth ground (if shielded wire is used).
SUPPLY AIR TEMPERATURE (33ZCSENSAT) SENSOR
INSTALLATION — The 33ZCSENSAT supply air temperature sensor is required for reheat applications or stand-alone
operation. The sensor has an operating range of –40 to 245 F
(–40 to 118 C) and includes a 6-in. stainless steel probe and
cable. The sensor is factory-supplied but must be relocated for
ducted heat. The SAT must be installed in the duct downstream
from the air terminal. The SAT sensor is also sometimes called
a duct air temperature sensor. Part number 33ZCSENSAT may
be used in place of the factory-installed sensor.
The SAT sensor probe is 6 inches in length. The tip of the
probe must not touch the inside of the duct. Use field-supplied
bushings as spacers when mounting the probe in a duct that is
6 in. or less in diameter.
If the unit is a cooling only unit, the SAT is not required.
If the unit is equipped with electric reheat, ensure that the
sensor is installed at least 2 ft downstream of the electric heater.
See Fig. 23 for the sensor location in this application.
If the unit has an octopus connected directly at the
discharge, install the sensor in the octopus. If the unit has an
electric heater, the two-foot minimum distance between the
sensor and the heater must be maintained. See Fig. 23 for the
sensor location in this application.
Disconnect electrical power before wiring the bypass controller. Electrical shock, personal injury, or damage to the
fan coil controller can result.
Do not run sensor or relay wires in the same conduit or raceway with Class 1 AC service wiring. Do not abrade, cut, or
nick the outer jacket of the cable. Do not pull or draw cable
with a force that may harm the physical or electrical properties.
Avoid splices in any control wiring.
Perform the following steps to connect the duct temperature
sensor to the bypass controller:
1. Drill or punch a 1/4-in. hole in the supply duct. See
Fig. 22. Duct sensor can be installed to hang from top of
duct or from the sides. Sensor probe can touch side of
duct.
Disconnect electrical power before wiring the zone controller. Electrical shock, personal injury, or damage to the zone
controller can result.

The sensor part number is 33ZCSENCO2. To mount the
sensor, refer to the installation instructions shipped with the
accessory kit.
The CO2 sensors (33ZCSENCO2) factory set for a range of 0
to 2000 ppm and a linear voltage output of 0 to 10 vdc. Figure 25
shows ventilation rates for various CO2 set points when outside
air with a typical CO2 level of 350 ppm is used. Refer to the
instructions supplied with the CO2 sensor for electrical requirements and terminal locations. The zone controller requires a
24 vac, 25 va transformer to provide power to the sensor.
To convert the CO2 sensor into a duct-mounted CO2 sensor,
the duct-mounted aspirator (33ZCASPCO2) will need to be
purchased.
To accurately monitor the quality of the air in the conditioned air space, locate the sensor near the return air grille so it
senses the concentration of CO2 leaving the space. The sensor
should be mounted in a location to avoid direct breath contact.
Do not mount the space sensor in drafty areas such as near
supply ducts, open windows, fans, or over heat sources. Allow
at least 3 ft between the sensor and any corner. Avoid mounting
the sensor where it is influenced by the supply air; the sensor
gives inaccurate readings if the supply air is blown directly onto
the sensor or if the supply air does not have a chance to mix with
the room air before it is drawn into the return air stream.
To accurately monitor the quality of the air in the return air
duct, locate the sensor at least 6 in. upstream or 15 in.
downstream of a 90-degree turn in the duct. The downstream
location is preferred. Mount the sensor in the center of the duct.
Do not run sensor or relay wires in the same conduit or raceway with Class 1 AC or DC service wiring. Do not abrade, cut,
or nick the outer jacket of the cable. Do not pull or draw cable
with a force that may harm the physical or electrical properties.
Avoid splices in any control wiring.
Perform the following steps to connect the SAT sensor to
the zone controller:
1. Locate the opening in the control box. Pass the sensor
probe through the hole.
2. Drill or punch a 1/4-in. hole in the duct downstream of the
unit, at a location that conforms to the requirements
shown in Fig. 23.
3. Use two field-supplied, self-drilling screws to secure the
sensor probe to the duct. Use field-supplied bushings as
spacers when installing the sensor probe in a duct 6 in. or
less in diameter.
Perform the following steps if state or local code requires
the use of conduit, or if your installation requires a cable length
of more than 8 ft:
1. Remove the center knockout from a field-supplied 4 x
2-in. junction box and secure the junction box to the duct
at the location selected for the sensor probe.
2. Drill a 1/2-in. hole in the duct through the opening in the
junction box.
3. Connect a 1/2-in. nominal field-supplied conduit between
the zone controller enclosure and the junction box.
4. Pass the sensor probe wires through the conduit and insert
the probe in the duct. Use field-supplied bushings as
spacers when installing the sensor probe in a duct 6 in. or
less in diameter.
5. Secure the probe to the duct with two field-supplied selfdrilling screws.
6. If extending cable length beyond 8 ft, use plenum rated,
20 AWG (American Wire Gage), twisted pair wire.
7. Connect the sensor leads to the zone controller’s wiring
harness terminal board at the terminals labeled SAT and
GND.
8. Neatly bundle and secure excess wire.
INDOOR AIR QUALITY SENSOR INSTALLATION —
The indoor air quality (IAQ) sensor accessory monitors carbon
dioxide levels. This information is used to modify the position
of the outdoor air dampers to admit more outdoor air as
required to provide the desired ventilation rate. Two types of
sensors are supplied. The wall sensor can be used to monitor
the conditioned air space; the duct sensor monitors the return
air duct. Both wall and duct sensors use infrared technology to
measure the levels of CO2 present in the air. The wall sensor is
available with or without an LCD (liquid crystal display) readout to display the CO2 level in ppm. See Fig. 24.
IMPORTANT: If the sensor is mounted in the return-air
duct, readjust the mixed-air dampers to allow a small
amount of air to flow past the return-air damper whenever the mixing box is fully open to the outside air. If the
damper is not properly adjusted to provide this minimum airflow, the sensor may not detect the indoor-air
quality during the economizer cycle.

The sensor must be mounted vertically on the wall. The
Carrier logo should be oriented correctly when the sensor is
properly mounted.
DO NOT mount the sensor in drafty areas such as near heating or air-conditioning ducts, open windows, fans, or over heat
sources such as baseboard heaters, radiators, or wall-mounted
light dimmers. Sensors mounted in those areas will produce inaccurate readings.
Avoid corner locations. Allow at least 4 ft between the sensor and any corner. Airflow near corners tends to be reduced,
resulting in erratic sensor readings.
Sensor should be vertically mounted approximately 5 ft up
from the floor, beside the space temperature sensor.
For distances up to 500 feet, use a 3-conductor, 18 or 20
AWG cable. A communication cable can be used, although the
shield is not required. The shield must be removed from the
sensor end of the cable if this cable is used. See Fig. 28 for
wiring details.
The power for the sensor is provided by the control board.
The board provides 24 vdc for the sensor. No additional power
source is required.
To wire the sensor, perform the following:
1. At the sensor, remove 4-in. of jacket from the cable. Strip
1/ -in. of insulation from each conductor. Route the cable
4
through the wire clearance opening in the center of the
sensor. See Fig. 28.
2. Connect the RED wire to the sensor screw terminal
marked (+).
3. Install one lead from the resistor (supplied with the sensor) and the WHITE wire, into the sensor screw terminal
marked (–). After tightening the screw terminal, test the
connection by pulling gently on the resistor lead.
4. Connect the remaining lead from the resistor to the
BLACK wire and secure using a closed end type crimp
connector or wire nut.
5. Using electrical tape, insulate any exposed resistor lead to
prevent shorting.
6. At the control box, remove the jacket from the cable and
route the RED conductor over to the left side of the control board. Route the remaining conductors to the right
side of the control board.
7. Strip 1/4-in. of insulation from each conductor and equip
each with a 1/4-in. female quick connect terminal.
8. Connect the RED wire to terminal +24v on the control
board.
9. Connect the BLACK wire to terminal GND on the control board.
10. Connect the WHITE/CLEAR wire to terminal RH/IAQ
on the control board.
11. Connect shield to ground (if shielded wire is used).

Indoor Air Quality Sensor Wiring — To wire the sensors
after they are mounted in the conditioned air space and return
air duct, see Fig. 26 and the instructions shipped with the sensors. For each sensor, use two 2-conductor 18 AWG twistedpair cables (unshielded) to connect the separate isolated 24 vac
power source to the sensor and to connect the sensor to the control board terminals. To connect the sensor to the control board,
identify the positive (+) PIN-8 and ground (GND) PIN-7 terminals on the sensor and connect the positive terminal to terminal
RH/IAQ and connect the ground terminal to terminal GND.
HUMIDITY SENSOR (WALL-MOUNTED) INSTALLATION — The accessory space humidity sensor is installed on
an interior wall to measure the relative humidity of the air within the occupied space. See Fig. 27.
The use of a standard 2 x 4-in. electrical box to accommodate the wiring is recommended for installation. The sensor can
be mounted directly on the wall, if acceptable by local codes.
If the sensor is installed directly on a wall surface, install the
humidity sensor using 2 screws and 2 hollow wall anchors
(field-supplied); do not overtighten screws. See Fig. 15.
Remote Occupancy Contact — The remote occupancy input (J4 pin 1) has the capability to be connected to a
normally open or normally closed occupancy dry contact. Wire
the dry contact as show in Fig. 29 between J4 Pin 1 and
24 VAC J1 Pin 1. The 24 vac necessary to supply the VVT®
zone controller remote occupancy contact input is supplied
using the zone controller.

Modulating Baseboard Hydronic Heating — Install the water valve on the leaving water end of the baseboard
heater. See Fig. 30. Observe the fluid flow direction when
mounting the valve. Be sure to properly heat sink the valve and
direct the flame away from the actuator and valve body when
sweating the valve connections. Install the leaving water temperature sensor (33ZCSENCHG) on the hydronic heating coil
as shown. The sensor accommodates nominal copper pipe
from 1/2 to 1-in. (OD sizes from 5/8 to 1.125 in.). It should be
secured to the pipe with the clamp supplied. If piping is larger
than 1-in. nominal size, a field-supplied clamp must be used.
Use fiberglass pipe insulation to insulate the sensor assembly.
Refer to Fig. 7 and 11 to wire the modulating water valve
and the sensor to the zone controller. Connect the leaving water
temperature sensor to the controller using the wiring connections shown for the SAT sensor. (NOTE: The leaving water
temperature sensor replaces the SAT sensor in this application.)
Use 18 or 20 AWG wire for all connections. The water valve
actuator housing may be used as a junction box if the leaving
water temperature sensor cable is not long enough and the
sensor cable must be extended to reach the controller.
For modulating hydronic heating applications, the default
configuration must be changed to properly control the valve.
Refer to the service configuration table and set the Heating
Loop parameters as follows:
Proportional Gain = 20.0
Integral Gain = 0.5
Derivative Gain = 0.0
Start Value = 102.0
Also, set the Ducted Heat decision to YES and set the
Maximum Duct Temperature decision equal to the design

NOTE: Conductors and drain wire must be at least 20 AWG
(American Wire Gage), stranded, and tinned copper. Individual conductors must be insulated with PVC, PVC/nylon, vinyl, Teflon, or
polyethylene. An aluminum/polyester 100% foil shield and an outer
jacket of PVC, PVC/nylon, chrome vinyl, or Teflon with a minimum
operating temperature range of –20 C to 60 C is required.
CONNECTION TO THE COMMUNICATION BUS
1. Strip the ends of the red, white, and black conductors of
the communication bus cable.
2. Connect one end of the communication bus cable to the
bridge communication port labeled COMM2 (if connecting on a secondary bus).
When connecting the communication bus cable, a color
code system for the entire network is recommended to
simplify installation and checkout. See Table 3 for the
recommended color code.
3. Connect the other end of the communication bus cable
to the terminal block labeled J2A in the zone controller
of the first air terminal. Following the color code in
Table 3, connect the Red (+) wire to Terminal 1.
Connect the White (ground) wire to Terminal 2.
Connect the Black (–) wire to Terminal 3.
4. Connect additional zone controllers in a daisy chain fashion, following the color coded wiring scheme in Table 3.
Refer to Fig. 31.
NOTE: The communication bus drain wires (shield) must be
tied together at each zone controller. If the communication bus
is entirely within one building, the resulting continuous shield
must be connected to ground at only one single point. If the
communication bus cable exits from one building and enters
another building, connect the shields to ground at a lightning
suppressor in each building where the cable enters or exits (one
point only).
→ Connect the Carrier Communicating Network Communication Bus — The zone controllers
connect to the bus in a daisy chain arrangement. The zone
controller may be installed on a primary bus or on a secondary
bus from the primary bus. Connecting to a secondary bus is
recommended.
At 9,600 baud, the number of controllers is limited to
128 zones maximum, with a limit of 8 systems (Linkage Coordinator configured for at least 2 zones). Bus length may not

4. At the air terminals, check fan and system controls for
proper operation. Verify that actuator screws are properly
tightened.
5. At the air terminals, check electrical system and connections of any optional electric reheat coil. If hot water reheat is used, check piping and valves against job drawings.
6. At the air terminals, make sure that all balancing dampers
at box outlets are in the fully open position.
7. If using an air source with field-installed controls, make
sure controls and sensors have been installed and wired
per manufacturer installation instructions.
8. At air source, verify that the motor starter and, if applicable, the Hand/Off/Auto (HOA) switch are installed and
wired.
START-UP
Use the Carrier network communication software to start up
and configure the zone controller.
All set-up and set point configurations are factory-set and
field-adjustable.
Changes can be made using the System Pilot or Carrier software. During start-up, the Carrier software can also be used to
verify communication with each zone controller.
For specific operating instructions, refer to the literature
provided with the software.
Perform System Checkout
1. Check correctness and tightness of all power and communication connections.
2. Check that all air terminals, ductwork, and zone controllers are properly installed and set according to installation
instructions and job requirements.

9. Check to be sure the area around the air source is clear of
construction dirt and debris.
10. Check that final filters are installed in the air handler(s).
Dust and debris can adversely affect system operation.
11. Verify that the zone controller and the air source controls
are properly connected to the communication bus.
12. Remember to utilize good duct design and to provide
sufficient straight duct at the inlet of the box. A minimum
of three times the inlet size is recommended.
Maintenance Screen, select the Zone Commissioning
Table and force the Commissioning Mode point to
Enable. Then select the Damper Cal point and force this
point to Enable. The controller automatically tests the
actuator by fully closing the damper.
It checks the fully closed position to determine if the
control was properly mounted. It then opens the damper.
The control scales the actual actuator travel range used to
a 0 to 100% open value. Finally the control will close the
damper, test, and zero the pressure transducer. When
completed, the control automatically removes the force
from the Damper Cal point. If a failure occurs at any
point during the testing, the Damper Calibration Status
point at the bottom of the screen will indicate ALARM
and the test will be aborted.
6. The actuator stroke has now been calibrated for the proper rotation.
Network Addressing — Use the following method
Fan and Heat Configuration and Test — Per-
when all the zone controllers are installed and powered, and the
SPT sensors are wired and functioning properly. This method
can be used if no addresses have been set previously. The
address of an individual zone controller may be set by using
the System Pilot. This is the standard method of setting the
address.
Each zone controller will default to an address of 0, 140
when its application software is initially loaded. Since multiple
controllers will be on the same bus, a unique address must be
assigned to each controller before the system can operate
properly. The assignment of controller addresses will be
performed through the System Pilot, as follows:
1. The System Pilot recognizes that the Zone Controller’s
address, stored in the zone controller memory, has not
been written yet (this will be true when the unit is first
powered up on the job, or after a jumper-initiated reset).
2. Press the override button on the SPT (terminals J4-14 and
J4-12 are shorted) for 1 to 10 seconds.
3. The zone controller address changes from 0, 140 to 239,
239 for a period of 15 minutes.
4. Use System Pilot to change the address from 239, 239 to
a valid system address within 15 minutes.
NOTE: If the address is not changed from 239, 239 to a valid
system address within 15 minutes, the controller will revert to
address 0, 140 and use of the override button will cause the
address function to repeat. The operator MUST actively set the
address even if the final desired address is 0, 140.
form the following procedure to configure and test the fan and
heat:
1. Display the Terminal Service Configuration screen to
make sure the proper Terminal Type and Heat Type are
configured. See the Configuration section to answer
questions about the individual configurations.
2. From the Diagnostics Maintenance Screen select the
Zone Commissioning table.
3. Force the Commissioning Mode to Enable.
4. If the terminal is a parallel or series powered fan box,
force the Fan Override to Enable. If the damper is open it
may have to be repositioned to the proper position
depending on the box type. Damper percent change will
be displayed. After the damper is positioned correctly, the
fan relay should energize and the fan should run for a few
seconds.
5. Make sure the fan runs and the Fan Override decision
returns to disabled to ensure the fan is wired correctly for
proper operation.
6. Force the Heating Override to Enable. If the unit is a
single duct unit, this must be done with the primary terminal at reheat set point. The damper will open to the reheat
cfm. The heat outputs will be commanded to provide
maximum heat. If the unit is a fan-powered terminal, the
fan must be on.
NOTE: The damper position settings can be found under
service configuration in the table AIRFLOW.
Initial Operation and Test — Perform the following
procedure:
1. Apply 24 vac power to the control.
2. Using the System Pilot, upload the controller from
address assigned in Network Addressing section above.
3. From the Terminal Service Configuration screen, properly configure the damper type and inlet size. If a round
inlet is used, then enter the size directly in the Inlet
Diameter decision. If a square, rectangular, or elliptical
damper inlet is supplied, then enter the inlet size in square
inches in the Inlet Area decision.
4. If the terminal damper closes in the CW direction, then no
adjustment is required. Otherwise, locate the damper
direction configuration decision (CW Rotation) and
toggle the value to OPEN by using the space bar. This
configuration decision is also located on the Terminal
Service Configuration screen.
5. After entering the area and rotation direction, verify operation of the damper. From the System Pilot Diagnostic,
System Balancing — To balance the system, perform
the following procedure:
1. Enable the balancing process by forcing System Commissioning to Enable.
2. Enable the All Zone Dampers to Max point.
3. The zone controller will send all system zone dampers to
their configured maximum positions and display the
values. Check the system maximum airflows to all zones
and set zone dampers while the system is at maximum
flow and the bypass damper is closed. Adjust maximum
damper position set points if required. The system can
also be balanced at design conditions with some dampers
closed.
4. If the user forces any zones to a new position, the new position is written to the zone’s maximum damper position
configuration value and the damper is repositioned.
5. Enable the All Zone Dampers to Min point.
Before starting the air source fan, make sure that dampers
at the system’s air terminals are not fully closed. Starting
the fan with dampers closed will result in damage to the
system ductwork.
27
6. The zone controller will send all system zone dampers to
their configured minimum positions and display the
values. Check the system bypass pressure and set the
pressure set point. Adjust minimum damper set points if
required.
7. If the user forces any zones to a new position, the new
position is written to the zone’s minimum damper position configuration value and the damper is repositioned.
8. Enable the Position Single Zone point.
9. The zone controller will send all system zone dampers to
their configured maximum positions and display the
values.
10. If the user forces any zones to a new position, the new position is written to the zone’s maximum damper position
configuration value and the damper is repositioned.
11. At this time, the user can force the Bypass Pressure set
point. Typically, the maximum unit rated duct static is
used. The zone controller will then write the forced
Bypass Pressure set point to the set point table in the
Bypass Controller by communicating over the network.
The bypass controller will then begin to control to the
new bypass pressure set point.
Status Table — The following sections describe the computer status screen which is used to determine status the zone
controller. The screens shown may be displayed differently

CONFIGURATION TABLES
The following sections describe the computer configuration
screens which are used to configure the zone controller. The
screens shown may be displayed differently when using different Carrier software. See Table 5.
Alarm Configuration Table — The Alarm Configuration Table (ALARMLIM) contains decisions used to configure
the alarm settings for the zone controller. This includes
re-alarm time, routing of alarms, limits for space temperature
and demand control ventilation.
RE-ALARM TIME — This decision is used to configure the
number of minutes the zone controller will wait before an alarm
condition which has not been corrected will be re-transmitted
on the communications network. Re-alarming of an alarm
condition will continue until the condition no longer exists.
Alarm Re-Alarm
Time:
Units
Minutes
Range
0 to 1440
Default Value
0 (Disabled)
ALARM ROUTING CONTROL — This decision indicates
which Carrier Proprietary Network system software or devices
will receive and process alarms sent by the zone controller. This
decision consists of eight digits each can be set to zero or one. A
setting of 1 indicates alarms should be sent to this device. A
setting of zero disables alarm processing for that device.
Currently the corresponding digits are configured for the
following devices: first digit — user interface software; second
digit — autodial gateway or Telink; fourth digit — alarm
printer interface module; digits 3, and 5 through 8 — unused.

Terminal Service Configuration Table — The Terminal Service Configuration Table (CONFIG) contains
decisions used to configure the main settings for the zone
controller. This includes Terminal Type, Primary Inlet Size,
and gains for the damper and heating PID loops. Decisions
regarding auxiliary heat are made in this table and up to
10 temperature readings can be configured for room temperature sensor averaging. SPT and SAT sensor trimming are done
here as well. See Table 6.
TERMINAL TYPE — This configuration is used to indicate
the terminal type that the zone controller is installed on. A 1 is
for Single Duct terminals, a 2 is for Parallel Fan terminals, and
a 3 is for Series Fan terminals.
Terminal Type: Range
1 to 3
Default Value
1
→ PRIMARY INLET SIZE — The Primary Inlet Size configuration is used to input the inlet diameter of the terminal if used
with a round inlet. The Inlet Area configuration is used for oval
or rectangular inlets. The zone controller will use the larger value for demand weighting if both values are configured. If both
inlet size and inlet area are zero, then the damper will not be included in the average demand calculations.
NOTE: Carrier sizes 12, 14, and 16 are oval.

DAMPER LOOP PARAMETERS — The loop gains and
start value define how the terminal will respond to deviations in
measured temperature in order control to the damper position.
The Proportional Gain is calculated each time the airflow is
compared to the active airflow set point. As the error from set
point goes to zero, the proportional term will also go to zero.
The Integral Gain is a running summation of all integral
terms since the loop started. This has the effect of trimming off
any offset from the set point which might occur, if only the
proportional term existed. Normally a proportional loop with
no integral term would require frequent adjustments of the
starting value to eliminate the offset as static pressure and other
conditions change.
The derivative gain tends to nullify or accelerate the changes in the proportional gain depending on the size of the error
from the set point. This allows the damper to respond faster
and more efficiently to accurately maintain the space temperature set points. The Start Value is the initial value that is then
modified by the error terms of the PID calculation.

CLOCKWISE ROTATION — This configuration is used to
define what effect a clockwise rotation of the actuator will have
on the damper. If the actuator rotates clockwise to closed position, the configuration should be set to Close. If the actuator rotates clockwise to open, the configuration should be set to
open. This configuration is used to change the rotation of the
actuator so that the damper transducer calibration will work
properly. The actuator does not have to be re-installed nor any
switches changed to reverse the action.

HEATING LOOP PARAMETERS — The heating loop
gains and start value define how the terminal will respond to
deviations in measured space temperature in order to control to
the heat set point.
The Proportional Gain is calculated each time the space
temperature is compared to the heat set point. As the error
from set point goes to zero, the Proportional Gain will also go
to zero.
The Integral Gain is a running summation of all integral
terms since the loop started. This has the affect of trimming off
any offset from set point which might occur if only the
Proportional Gain existed. Normally a proportional loop with
no Integral Gain would require frequent adjustments of the
starting value to eliminate the offset as loading conditions on
the room change.
The Derivative Gain is not needed. This term tends to
nullify large changes in the Proportional Gain for dampened
response.
The Start Value is the initial value that is then modified by
the Error terms of the PID calculation.

Linkage Configuration Table — The Linkage Configuration Table (LINKAGE) contains decisions used to
configure the linkage coordinator zone controller's linkage
settings. This is where the linkage coordinator zone controller,
the air source and the bypass controller options are configured.
It also includes Carrier Network Function Configuration used
for collecting data from multiple controllers and finding the
high, low or average value and transferring the data to another
controller. This table is also used to setup Temperature Sensor
Grouping, which is the sharing of one space temperature sensor
among multiple zone controllers. See Table 9.
LINKAGE MASTER ZONE — This decision defines if the
zone controller will function as a Linkage Coordinator
(Linkage Master) for itself and other zones.
If the zone controller is to use a supply air sensor for
stand-alone operation, this configuration must be configured to
No and the number of Zones to 1.
If the zone controller will use its primary air sensor to determine the air handler mode for a number of zone controllers,
configure this configuration to Yes, input the number of zones,
and leave the air source decisions at the default values of zero.
If this zone controller will communicate linkage information with an air source, configure this configuration to Yes. The
number of zones must be configured and the address of the air
source entered.
Linkage
Master Zone:
Range
Yes/No
Default Value
No
NUMBER OF ZONES — This decision defines the number of
zone controllers (including itself) for the Linkage Coordinator to
scan and include as part of the average temperature, set points,
and occupancy information to the air source. The address of the
zone controller functioning as a Linkage Coordinator must be
larger than the number of zones configured. The zone controller
will scan addresses less than its own, including information for
as many zones as are configured. Other zone controller configured as linkage coordinators will also be included, so it is possible to have zones scanned by more than one linkage coordinator.
Therefore care must be taken in addressing to prevent overlapping systems, unless overlapping systems is necessary. In large
buildings the use of bridges and multiple busses is recommended
to improve communication and provide system differentiation.
Number of
Zones:
Range
1 to 32
Default Value
1
33
AIR SOURCE BUS AND ELEMENT NUMBER — The Air
Source Bus and Element Number configurations define the
address of the air source providing conditioned air to the zones
controlled by the linkage coordinator. If the address is left at
zero, the linkage coordinator will look for a primary air sensor
to determine the equipment mode. If no primary air sensor is
installed, or the sensor fails, the Linkage Coordinator will
default the air source mode to Cooling.

TEMP SENSOR GROUPING — Each zone controller has
the capability to broadcast the associated space temperature
sensor’s data or listen to another controller’s sensor data over
the network. All controllers sharing the same sensor must be
installed on the same communication bus.
There are three configuration decisions that must be configured in order to share sensors. The Temp Sensor Mode is used
to specify if a controller will use its own local sensor, broadcast
its local sensor, or listen to another controller’s sensor broadcast. The Listen Sensor Config is used to specify if the controller is sharing the space temperature information only or the
space temperature and temperature offset slidebar information.
The Broadcast Element Number decision is used to specify
which controller number a zone will listen for when configured
to receive another controller’s broadcast.

SYSTEM BYPASS EXISTS — This decision is used to tell
the linkage coordinator that an optional bypass controller does
or does not exist in this system. If this decision is set to Yes, the
linkage coordinator will attempt to communicate with a bypass
controller whose address must be one higher than the linkage
coordinator. If this decision is set to No, the linkage coordinator
will not attempt to communicate with a bypass controller.
System
Bypass Exists:
Range
Yes/No
Default Value
Yes
→ AST MODE VERIFICATION — This decision is used to tell
the linkage coordinator whether or not to qualify the mode sent
to it by comparing the air source supply air temperature value
to space temperature to ensure the air source is discharging an
appropriate supply air temperature for the current heat/cool
mode. If heating is required but the supply air temperature is
too cool for heating, the zone controller will act as if the air
source mode is cool rather than heat.
AST Mode
Verification:
Range
Yes/No
Default Value
No
→ AST SENSOR LOCATION — This decision is used to specify where the air source supply air temperature sensor is
located. It may be located at the air source, at the bypass controller, or there may be an optional primary air temperature
sensor (PAT) installed in the primary air duct.

CCN LINKAGE DATA — A zone controller configured as a
linkage coordinator has the ability to poll its linked zones and
collect the high, low or average value of any variable within its
linked zones. Once the high, low or average is determined, the
linkage coordinator can then transfer that value to a configured
bus number, element number and point name. Typically this
feature is used to determine a system’s highest indoor air quality reading.
In order to utilize this feature the CCN Variable Name being
collected from the linked zones must be supplied. The data
transfer rate must be specified and whether the high, low,
or average value is being determined. After the value has been
determined, a valid point name and communication bus
address to transfer the value to must be entered.

language that will be seen on all user interfaces for this controller. By default, the zone controller displays information in
English. To change to a second language display, set this
decision to No, download this table and then upload the zone
controller to see the factory-loaded second language. If a second language is not available in this module, this decision will
be disregarded and information will continue to be displayed in
English.

Master (Linkage Coordinator) Service Configuration Table — The Master (Linkage Coordinator) Service
Configuration Table (MASTER) contains decisions used by
the linkage coordinator zone controller to determine the system
demand mode (heat/cool/vent). See Table 10.
COOL START AVERAGE DEMAND — This decision is
used to configure the minimum average cooling demand that
must be met before the system will start in cooling mode if no
mode is currently active.
NOTE: If there is also an average heating demand, and it is
also greater than its configured minimum average heating
demand (Heat Start Avg. Demand), then the mode with the
greater demand will be selected. If both heating and cooling
average demand are exactly the same then the mode with the
greatest individual zone demand will determine the starting
system mode.

Time Schedule Configuration Table — The Time
Schedule Configuration Table (OCCDEFCS) contains
decisions used to configure the zone controller’s occupancy
schedule. For flexibility of scheduling, the occupancy configuration is broken into eight separate periods. See Table 11.
MANUAL OVERRIDE HOURS — The Manual Override
Hours decision is used to command a timed override by entering the number of hours the override will be in effect.
If the occupancy schedule is occupied when this number is
downloaded, the current occupancy period will be extended by
the number of hours downloaded.
36
If the current occupancy period is unoccupied when the
occupancy override is initiated, the mode will change to
occupied for the duration of the number of hours downloaded.
If the occupancy override will end after the start of the next
occupancy period, the mode will transition from occupancy
override to occupied without becoming unoccupied, and the
occupancy override timer will be reset.
An active occupancy override or a pending occupancy
override may be canceled by downloading a zero to this
configuration. Once a number other than zero has been downloaded to this configuration any subsequent downloads of any
value other than zero will be ignored by the zone controller.

OCCUPANCY SCHEDULING — For flexibility of scheduling, the occupancy programming is broken into eight separate
periods. For each period the scheduling, the active days of the
week, occupied start time, and occupied stop time needs to be
configured.
DAY OF WEEK — This configuration consists of eight fields
corresponding to the seven days of the week and a holiday
field in the following order: Monday, Tuesday, Wednesday,
Thursday, Friday, Saturday, Sunday, Holiday. A separate
configuration screen is used.
If a 1 is configured in the corresponding place for a certain
day of the week, the related “Occupied from” and “Occupied
to” times for that period will take effect on that day of the
week. If a 1 is placed in the holiday field the related times will
take effect on a day configured as a holiday. A zero means the
schedule period will not apply to that day.
Period (1-8):
Day of Week:
Range
0 or 1
Default Values
11111111 for period 1,
00000000 for periods 2-8.
OCCUPIED FROM — This field is used to configure the
hour and minute, in military time, when the mode for the zone
controller becomes occupied.
Period (1-8):
Occupied from: Units
Hours: Minutes
Range
00:00 to 24:00
Default Value

→ OVERRIDE — The Override parameter is used to configure
the number of hours and minutes the override will be in effect.
The user initiates override by pressing the override button on
the space temperature sensor. This will cause the schedule to
enter into the Occupied mode. If global scheduling is used, all
zones using the global schedule will enter Occupied mode.
Pushing the override button during Occupied mode will have
no effect.
If the occupancy override is due to end after the start of the
next occupancy period, the mode will transition from occupancy override to occupied without becoming unoccupied, and the
occupancy override timer will be reset.
NOTE: If using the tenant billing function, the override
hours set point must be configured between 1 and 3 hours.

SET POINT GROUP NUMBER — The Set Point Group
Number is used to define the current zone controller as a part of
a group of zone controllers which share the same set points. All
zone controllers with the same Set Point Group Number will
have the same set points. The set points are broadcast to the
group by the zone controller defined by the Global Set Point
Master configuration. A value of 0 is a local schedule. Values 1
to 16 are used for global scheduling.
Set Point
Group Number: Range
0 to 16

Option Service Configuration Table — The Option Service Configuration Table (OPTIONS) contains
decisions used to configure the service options of the zone
controller. This includes such things as whether the zone
controller is a global schedule master, a global set point master,
a broadcast acknowledger, and whether it will be using demand
control ventilation. This is also where loadshed parameters are
configured. See Table 12.
OCCUPANCY SCHEDULE NUMBER — The Occupancy

LOADSHED OFFSET ADJUST — This decision is used to
configure an amount by which the Occupied Heating and
Occupied Cooling set points will be relaxed in response to a
redline broadcast. The zone controller responds to a loadshed
event similar to a redline event, if the loadshed command is
preceded by a redline event.
Specifically, if the unit is already in redline when the loadshed command is received, the zone controller will drop one
stage of heat if heating, provided there is more than one stage
available.
If the unit is in cooling, the zone controller uses the Loadshed Offset Adjust to raise the cooling set point, if raising the
sepoint by this amount will cause the space to be satisfied.
Also, if the system experiences a loadshed event while not
in redline, it will treat the event as a redline event and raise
or lower the cooling and heating set points by the amount
configured in this decision.

DAMPER ACTUATOR CALIBRATION — The Damper
Actuator calibration is the first calibration which should be performed on a newly installed actuator. The zone controller will
command the actuator to close and read the feedback potentiometer to determine the zero position of the damper. It will
then command the damper to fully open. The zone controller
will read the potentiometer to determine the maximum open
position. Damper positions from closed to maximum open will
be scaled to read 0 to 100% for the damper position.
The zone controller will then close the damper and open it
once more to zero calibrate the airflow sensor. The entire
calibration procedure can take up to 3 minutes. If the damper

OPERATION
System Mode Selection — The Linkage Coordinator
will determine whether the system as a whole requires heating
or cooling and whether the air source will operate in occupied
or unoccupied mode. This will be determined by obtaining the
heating or cooling needs of each zone and adjusting for the
duct size of the zones and calculating an average cool demand
(ACD) and average heat demand (AHD) as well as its
occupancy mode. The Linkage Coordinator will be the highest
addressed zone controller of all zones that are served by
the same air source equipment and it will obtain this information when it scans all its associated zones on approximately
1-minute intervals.
When using the Occupied Heating Set Point (OHS) or
Occupied Cooling Set Point (OCS) the actual configured values will be used including T56 biased offset (if present) as the
zone operating set points. The T56 bias is not applied to Unoccupied Heating and Cooling Set Points.
Temperature demand will be used to indicate individual
zone demand and for accumulating the total weighted average
demand for heating and for cooling. If the space temperature
(SPT) is greater than the OCS then the zone demand is cooling
and the space temperature will be used in the ACD. If the SPT
is less than the OHS than the zone demand will be heating and
the space temperature will be used in the AHD. If the SPT is
between the OHS and OCS, the zone will be considered to
have no demand and will not be included in determining the
system mode. Only those zones with a valid SPT of greater
than –40 F, less than 245 F, and a configured damper size
greater than 0 will be included in the calculations.
If any zone is occupied then the Linkage Coordinator will
calculate the ACD and AHD using only the occupied zones. If
no zones are occupied will then the Linkage Coordinator will
calculate the ACD and AHD including all zones in the calculation. The zone controller then display the ACD, the Max Cool
Demand and Max Cool Demand Zone, the AHD, the Max
Heat Demand Max Cool Demand Zone, the Reference Zone
Demand and Zone Identification for each demand in the

air source to be controlled by the demands of the zones and
allows the zones to properly respond to the changes in the air
source operating modes. Linkage operation in air sources that
have Carrier communicating network controls such as
48/50HG, 48/50A, and 48/50Z Product Integrated Controls
(PIC) series rooftop units, PremierLink™ control or Universal
Controller is supported. Existing air sources that do not have
Carrier communicating network controls may be retrofitted
with PremierLink or a Universal Controller depending on the
equipment type. The designated Linkage Coordinator of each
system will be the Linkage Coordinator between the air source
and its associated zones.
AIR SOURCES THAT SUPPORT LINKAGE — Air sources with PICs or PremierLink controls do not require any
configuration settings to establish linkage with the Linkage
Coordinator. This is done automatically when the air source
bus and element address are configured in the Linkage Coordinator’s LINKAGE configuration table. The linkage information that is supplied to the air source by the Linkage Coordinator is as follows:
• Reference zone temperature
• Reference zone occupied biased heating and cooling
setpoints
• Average unoccupied heating and cooling set points of all
zones serviced by the air source
• Composite occupancy mode
The air source will control the equipment based on this
information and in return will provide the Linkage Coordinator
with the following data:
• Operating mode — Cooling, Heating, Free Cool, Pressure, Evacuation or Off
• Supply-air temperature
This synchronization of data optimizes the efficiency of the
air source and the zones to operate at peak system performance
at all times. This information can be seen in linkage maintenance tables of the Linkage Coordinator and the air source and
is updated at approximately 1-minute intervals.
The reference zone temperature that is sent by the Linkage
Coordinator will vary depending on the current demand. At
times this will be a calculated value instead of an actual value
to allow the air source to turn off heating or cooling after the
current mode is satisfied or as it makes a transition to a mode.
Table 24 defines when these values will be sent and how they
are determined.
If no mode is currently active, the Linkage Coordinator will
determine the mode by first comparing the AHD and the ACD.
If only one demand is greater than the start demand (Heat Start
Avg. Demand or Cool Start Avg. Demand in the Master [Linkage Coordinator] Service Configuration table), the system will
start in that mode. If both average demands are greater than the
configured minimum average demand required to begin a
mode, then the mode with the greatest demand will be selected.
If both heating and cooling average demand are exactly the
same then the mode with the greatest individual zone demand
will determine the system mode.
Once the mode is selected, the information is communicated to its air source via the Linkage Coordinator so that the air
source may respond to the requested mode. The Linkage Coordinator also has the capability of locking out the mode based on
the outside air temperature (OAT). If the OAT has exceeded the
lockout set point for that mode, then the Linkage Coordinator
will not request that mode from the air source. There is a fixed
3° F hysteresis on the heating and cooling set points before a
mode is re-enabled.
Once a mode has begun, the system mode reselect timer is
started to monitor the elapsed time of the operating mode. A
mode will end when the average demand for that mode drops
below the average demand hysteresis for the mode (Heat Mode
Hysteresis or Cool Mode Hysteresis in the Master [Linkage
Coordinator] Service Configuration table). If a system mode is
currently active and the average demand for the opposite mode
becomes greater than the current mode average demand, and
the opposite mode demand is also greater than the mode Start
Avg. Demand for that mode, then the system mode may
change but only after the system mode reselect time of the current mode exceeds the configured System Mode Reselect timer
value. If these are all true, the system will begin the change to
the opposite system mode. This is accomplished by sending information to the air source that ends the current mode. The
Linkage Coordinator then waits for the supply-air temperature
(SAT) to fall within the ventilation temperature range of 65 to
75 F. Once that occurs, the opposite mode is started.
If the mode is dropped due to the reselection criteria
above, the algorithm will not permit the original mode to be
re-established unless there is sufficient average demand to start
the new mode. This is true even if the old mode has once again
become the more dominant requirement.
Linkage — Linkage is the process used to communicate
between the air source (HVAC equipment) and the zone terminals to form a coordinated HVAC system. Linkage allows the

NON-LINKAGE CONTROLLED AIR SOURCES — In systems with Non–Linkage central air sources or central air
sources that do not support Linkage, the zone coordination
function of Linkage can still be provided by the Linkage function contained within a Linkage Coordinator. In these cases, the
zone configured as the Linkage Coordinator will determine the
operational mode of the air source through its bypass controller
pressure sensor. Once the air source is determined to be operational, the Linkage Coordinator will attempt to determine the
air source mode (heating or cooling) by measuring the supply
air temperature from the air source by either a primary air
temperature sensor or a bypass duct temperature sensor. A
field-supplied primary air temperature sensor is required.
The modes that can be determined are Cooling, Heating,
Free Cooling, or Off. If a sensor is not installed, or the sensor
fails, then the Linkage Coordinator will default to the cooling
mode. The mode and air source status is then transmitted down
to the zones by the Linkage Coordinator.
NOTE: If Linkage communication should fail between a
linked air source and its Linkage Coordinator for more then
5 minutes, the Linkage Coordinator will generate a Linkage
Failure alarm and will revert back a Non-Linkage air source
control. Once Linkage communication has been re-established
it will automatically begin controlling the air source.
HEAT MODE — The linked air source is in heat mode due to
a request for from Linkage Coordinator. For a non-Linkage
controlled air source, when the fan is determined to be on, the
Linkage Coordinator controller reads the primary air temperature value. If the duct temperature is 5° F greater than the
reference zone temperature and the reference zone is greater
than 65 F, or if the reference zone is less than 65 F and the duct
temperature is 10° F greater than the reference zone temperature, then the mode is determined to be heating.
COOL MODE — The linked air source is in cool mode due to
a request for from Linkage Coordinator. For a non-linkage
controlled air source, when the fan is determined to be on, the
Linkage Coordinator controller reads the primary air temperature value. If the temperature is less than the reference zone
temperature, as calculated by the Linkage Coordinator controller, minus 2° F, the mode is determined to be cooling.
FREECOOL MODE — The following conditions must be
present in the linked air source for free cooling mode:
• the average zone temperature value is greater than the
average unoccupied zone cooling temperature set point
• the current time is between 3:00 AM and 7:00 AM
• the air source is providing cooling to the system
If the above conditions are true, then the mode is determined to be Free Cooling. This mode is then communicated to
all zone controllers associated (linked) with the Linkage
Coordinator controller. For a non-Linkage controlled air
source, this will be same as COOL mode if the criteria for
COOL mode is met as described above.
PRESSURIZATION MODE — If the linked air source has
its optional Pressurization input closed, it will transmit this
mode to the Linkage Coordinator. If this mode is active then all
zones will open the dampers to the cooling maximum damper
position, series fan boxes will have their fans forced on and
parallel fan boxes will have their fan forced off. This mode is
not available for if there is a non-Linkage controlled air source.
EVACUATION MODE — If the linked air source has its optional Fire Shutdown or Evacuation input closed, it will
transmit this mode to the Linkage Coordinator. If this mode is
active then all zone dampers will be fully closed and series and
parallel fan boxes will have their fans forced off. This mode is
not available for if there is a non-Linkage controlled air source.
System Modes — The following modes are determined
by the Linkage Coordinator through the Linkage data exchange
when there is a linked, controlled air source or by using its
bypass controller and primary air sensor if the there is a
non-linkage controlled air source. Some modes will not be
available if the there is a non-Linkage controlled air source. All
the listed modes are available if there is a linked Carrier
communicating network controlled air source depending on the
available input options of the of the air source. Each mode
description identifies if and how that mode is determined if
there is a non-linkage controlled air source.
OFF MODE — The linked air source will determine this
mode based on its fan status input under normal operating
conditions. For a non-Linkage controlled air source, the
Linkage Coordinator will determine if the air source is operational (the fan is on) by determining if the bypass pressure can
be measured. If no pressure can be measured then the Linkage
Coordinator controller concludes that the air source is off and
all zone dampers will go to 70% open. If pressure is measured,
then the Linkage Coordinator concludes that the air source in
on. If no bypass controller is present then the system will be
considered to be always on.
Air Terminal Modes — Once the system mode is established the terminals will control their dampers to maintain
the zone temperature in the space. Table 25 list a brief description of their operation. For a detail description of the terminal
modes and their operation, refer to the 3V™ Control System
Application manual.

Carrier Controls representative if you need assistance with this
application.
ZONE DAMPER VENTILATION — After the zone has satisfied and the system mode is Cooling or Free Cooling and the
SAT is between 65 and 75 F, the damper will go to its Ventilation Position or the Cool Minimum Position, whichever is
greater. If the SAT is less then 65 or greater then 75 or the
system mode changes to Heating, the damper go to the current
system mode Minimum Position. The Ventilation Damper
Position is defined in the Damper service configuration table.
DEMAND CONTROL VENTILATION (DCV) — If the zone
controller has a CO2 Demand Ventilation sensor it will be able
to override the temperature controlled damper position if it is
occupied, the system mode is Cooling or Free Cool, and the
zone is does not have a demand for heat. When the IAQ sensor
exceeds the configured Demand Vent set point it will use a PID
algorithm to calculate a higher damper position to allow more
airflow to the zone in order to dilute the CO2 levels. The
Demand Ventilation algorithm has a higher priority then the
temperature control algorithm under these conditions so the
damper will be controlled to the greater of the two values. The
DCV mode, when active, overrides the Cool Minimum and
Ventilation Positions. As the CO2 levels decrease in the zone
the damper will soon be returned to normal temperature
control.
If the zone is configured for modulating ducted reheat and
the zone temperature decreases to less than half way between
the heat and cool set point then the reheat will be enabled to
prevent the zone from going into the heat mode. If the zone is
configured for any other type of reheat it will NOT be energized. If the temperature continues to decrease below the heat
set point, the DCV mode will be disabled and the zone will resume normal temperature control.
The zone ZNMAINT maintenance status table will display
the calculated damper position and if the temperature or DCV
is in control of the damper as well as other information such as
occupancy status, heat and cool set points, reheat sub-master
reference and whether local heating or cooling is in effect.
LOADSHED — The zone controller can respond to a redline
or loadshed broadcast from an optional Loadshed module installed on the Carrier communicating network. The purpose of
this function is to monitor and conserve electrical power usage.
If a redline command is broadcast the zone controller expand
its heat and cool set points by the amount that is configured in
Loadshed Offset Adjust decision in the OPTIONS service configuration table. The default is 2° F so this amount would be
subtracted from the heat set point and added to the cool set
point if is left unchanged. A configurable redline/loadshed delay timer (Maximum Loadshed Time decision in the OPTIONS
service configuration) will also started to prevent the set points
from being expanded indefinitely.
If a Loadshed command is broadcast then the set points will
be expanded and the zone controller will drop 1 stage of reheat
providing that the reheat option is enabled and there is more
than one stage of heat. The set points will be returned to normal
and additional staged heat will be allowed when the redline/
loadshed command is canceled by the Loadshed Module, the
zone controller’s internal redline/loadshed delay timer times
out or the zone becomes unoccupied. Contact your local
Carrier Controls representative for more information on this
application.
The zone controller can be configured for one of three types
of air terminal control - single duct, series fan or parallel fan. If
configured for parallel fan, the fan will be energized whenever
the there is a demand for heat the system mode is not Heating
and when there is a demand for heat when the zone is unoccupied and the system mode is not Heating. If configured for
series fan, the fan will be energized whenever the zone is
occupied and when the there is a demand for heat when it is
unoccupied. To prevent all series fan zones from starting at one
time, the zone controller will run a start delay algorithm based
on the zone controllers address to stagger the fan start time.
Before starting the fan is started the zone damper will go to the
fully closed position to prevent the fan from starting backwards. The following formula is used to delay the fan start in
second:
Delay time in seconds = (((Whole Remainder of Element#/
20)*60)+20)
ZONE DAMPER TEMPERATURE CONTROL — The damper will modulate to adjust the airflow to the space to maintain
its current set point. The damper is controlled by a PID loop to
provide precise control of the damper position. The damper
will be modulated opened if the system mode and local mode
are the same. As the zone temperature gets closer to the set
point, the damper will modulate to the Minimum Damper
Position. The amount the damper will be open at any given
time depends on how far away the temperature is from the set
point, how fast it takes to satisfy the mode, and the Minimum
and Maximum Positions for current mode. Once the zone is
satisfied the damper will go to its Minimum Damper Position
for that mode. Cool/Heat Minimum and Maximum Positions
are defined in the Damper service configuration table.
If the local zone temperature is different from the system
mode then the damper will be at Minimum Position for the
system mode.
ZONE DAMPER REHEAT — If the zone controller has
optional reheat installed, it will use this heat to maintain the
heating set point. There are 4 types of heat options available as
listed below:
• Modulating hot water or steam (requires a supply air
temperature [SAT] sensor for ducted heat or a leaving
water temperature sensor for baseboard heat)
• Two-position hot water or steam (SAT required)
• 1 to 3 stages of electric heat (SAT required)
• Combination of staged baseboard and ducted heat (SAT
required)
If the zone controller is configured for single duct terminal,
the system mode is cooling, and the zone local mode is heating
the damper will go to the configured Reheat Minimum Position
or the Cool Minimum Damper Position (as configured in the
Damper service configuration table) whichever is greater, and
reheat will be energized.
If the zone controller is configured for series or parallel fan
terminal the zone controller will close the damper to the Cool
Minimum Position before energizing the reheat. For parallel
zone terminals the fan will be energized as the first stage of
heat. The zone controller uses a PID algorithm to calculate a
supply air or leaving water temperature, which the reheat will
be controlled to, in order to satisfy the heat demand.
If the system mode is Heating, the zone controller will try to
heat the zone with the central heat but may energize reheat to
satisfy the demand if it is required. If the terminal type is configured for parallel fan the fan will remain off. If no reheat
is desired in the zone while central heat is on or under any

VVT® system key components
Terminal control
Bypass controller (33ZCBC-01) — The VVT bypass
controller is a component of Carrier’s 3V™ control system
and is used to regulate the supply duct static pressure for
Variable Volume and Temperature Applications. The
bypass Controller is an essential system component that
allows constant volume HVAC equipment to provide zone
level temperature control.
VVT zone controller (33ZCVVTZC-01) — The VVT
Zone Controller is a component of Carrier’s 3V control
system and is used to provide zone level temperature and
air quality control for Variable Volume and Temperature
Applications. The VVT zone controller is a pressure dependent device that maintains space temperature by modulating the amount of supply airflow through its primary
damper. An integrated 35 in.-lb actuator is standard on all
VVT zone controllers.
VVT zone controllers are available factory mounted to
Carrier’s round and rectangular dampers. Round dampers
are available in 6, 8, 10, 12, 14, and 16-in. sizes. Rectangular dampers are available in 8x10, 8x14, 8x18, and
8x24-in. sizes. All damper assemblies are equipped with an
integrated duct temperature sensor.
Zone controllers are available for field retrofit applications.
VAV zone controller (33ZCVAVTRM, 33ZCFANTRM) —
Carrier’s 3V control system provides seamless integration
of pressure independent zones for use with VVT systems.
Simply use Carrier’s family of VAV zone controllers
(ComfortID™) to regulate the flow of conditioned air into
the space. The VAV zone controllers provide dedicated
control functions for single duct terminals with modulating
heat (up to 2-stages of heat), series fan or parallel fan powered terminals, or as a primary controller for dual duct or
zone pressurization applications. Refer to Carrier’s ComfortID literature for additional information.
Linkage compatible unit controls and auxiliary
controls
Carrier’s 3V control system provides optimized equipment
control through airside linkage. Linkage allows the air
source to adjust its supply air temperature set points and
occupancy schedules to run in the most efficient manner.
The 3V control system linkage compatible controllers
include ComfortLink™, PremierLink™ and the Universal
Controller.
ComfortLink™ controls — The factory-integrated controls are available on Carrier’s 2 to 25 ton Centurion
rooftop product line. The ComfortLink controller is a
component of Carrier’s 3V system and provides: optimum
performance of the rooftop’s refrigeration circuits, an
easy to read English scrolling marquee display and user
interface, and unparalleled diagnostic information with
factory-mounted sensors.
PremierLink™ control (33CSPREMLK) — The
PremierLink communicating controller is available as a factory-installed option on 3 to 25 ton rooftop units and as a
field-installed accessory. The PremierLink controller is plug
and play compatible with all Carrier communicating controls including ComfortLink. The control is DCV (Demand
Controlled Ventilation) compatible and internet ready.
3
Universal controller (33UNIVCTRL-01) — The Universal Controller provides auxiliary building control to
interface with lighting, fans, pumps and other HVAC
equipment in a stand-alone or Carrier-networked environment using closed-loop, direct digital controls. The Universal Controller’s pre-engineered algorithms provide simple
building integration for small-to-medium commercial
applications with 16 field point capability (8 inputs and
8 outputs).
Interface devices
System Pilot — The System Pilot is a component of
Carrier’s 3V control system and serves as the user-interface
and configuration tool for all Carrier Communicating devices. The System Pilot can be used to install and commission
a 3V zoning system, linkage compatible air source, universal controller and all other devices operating on the Carrier
communicating network.
ComfortVIEW™ software — ComfortVIEW software
can be installed on a PC and is used to configure and monitor the 3V system.
Remote monitoring capability device — The remote
monitoring device installs on the Carrier network and
provides a connection for a phone line or ethernet connection, allowing the user to view and change information
using a standard web browser. The user will also have
access to the point displays, set point schedules, and operating schedules.
Field-installed accessories
Option board (33ZCOPTBRD-01) — Carrier’s optional relay board may be used with VVT zone controllers to
provide control functions for heat or fan air terminals.
Heating capabilities include modulating heat, up to 3 stages of ducted heat or combination baseboard and ducted
heat control.
Mounting kit — Mounting kits are used to field install the
VVT zone controllers onto Carrier 33CS dampers. Mounting kits come in packages of 10. The 33ZCMBRC-01 kit is
used when mounting on rectangular dampers. The
33ZCMBRD-01 kit is used when mounting on round
dampers.
Sensors
Outdoor-air sensor (HH79NZ039) — The outdoor-air
sensor reads temperatures between 0° and 150 F and is
used to report the outdoor-air temperature to the communication bus. The information can be used to lock out heating or cooling modes when the temperature is not within
user-configured limits. The outdoor-air sensor is needed
when an economizer is used.
Supply air temperature sensor — The 33ZCSENSAT
supply air temperature sensor is required for heating applications or stand-alone operation. The sensor has an operating range of –40 to 245 F (–40 to 118 C) and includes a
6-in. stainless steel probe and cable.
Duct temperature sensor (33ZCSENDAT) — The
duct temperature sensor is required for use with a bypass
controller and must be installed in the supply air duct. The
33ZCSENDAT is the recommended sensor for cooling
operation.
VVT® system key components (cont)
For bypass systems, the duct temperature sensor should
be moved to a location which will provide the best sensing
of the supply-air temperature during heating and cooling.
For bypass systems using a ducted supply, the duct temperature sensor should be located in the main supply duct
downstream of the discharge of the air source and before
the bypass damper to allow good mixing of the supply airstream.
Primary air temperature sensor — The primary air
temperature (PAT) sensor (part number 33ZCSENPAT) is
used on a zone controller which is functioning as a Linkage
Coordinator for a non-communicating or Linkage compatible air source.
Space temperature sensor — A space temperature
(SPT) sensor must be installed for each zone controller.
There are 3 types of SPT sensors available from Carrier:
the 33ZCT55SPT space temperature sensor with
timed override button, the 33ZCT56SPT space temperature sensor with timed override button and set point adjustment, and the 33ZCT59SPT space temperature sensor
with timed push button override button, set point adjustment and digital readout display.
4
The space temperature sensor is used to measure the
building interior temperature and should be located on an
interior building wall.
Air quality sensor (CO2) — An indoor air quality sensor
is required for optional Demand Controlled Ventilation.
The 33ZCSENCO2 CO2 sensor is an indoor, wall-mounted
sensor with an LED display. The 33ZCT55CO2 and
33ZCT56CO2 CO2 sensors are indoor, wall-mounted sensors without display.
NOTE: The relative humidity sensor and CO2 sensor cannot be used on the same zone controller.
Humidity sensors — The relative humidity sensor is required for zone humidity control (dehumidification) for
pressure independent zones only. The indoor wallmounted relative humidity sensor (33ZCSENSRH-01) or
duct mounted relative humidity sensor (33ZCSENDRH-01)
can be used.
NOTE: The relative humidity sensor and CO2 sensor cannot be used on the same zone controller.

b. If the zone requirement is heating, all single
duct terminals shall maintain their damper
position at 70%. Any zone controller servicing
a parallel or series box shall fully close their
dampers while the fan is operating. If local
heat is available, the series and parallel fans
shall start and local heat shall be enabled to
maintain its unoccupied heating set point. The
damper shall be modulated open to 70% after
heating is no longer required.
2. Cooling and Night Time Free Cooling (NTFC):
a. If the zone requirement is none, then the
zone controllers shall modulate their dampers to maintain their minimum cooling
damper position or damper ventilation position if the supply air temp is between 65 and
75 F. Any zone controllers servicing Series
terminals shall also modulate their dampers
to maintain their minimum cooling damper
position or damper ventilation position if the
supply air temp is between 65 and 75 F
after completing their SFTP cycle. During
the NTFC mode the zone controller shall
control between its heating and cooling set
points. During the other modes the zone
controller shall modulate its damper to its

Features/Benefits
Flexibility for every application
User interface
The VVT® zone controller is a single duct, variable volume
and temperature terminal control with a factory-integrated
controller and actuator. The VVT zone controller maintains
precise temperature control in the space by regulating the
flow of conditioned air into the space.
Buildings with diverse loading conditions can be supported by controlling reheat (single duct only) or supplemental heat. The VVT zone controller can support
two-position hot water, modulating hot water, 3-stage electric heat, or combination baseboard and ducted heat.
The VVT zone controller is designed to allow a service person or building owner to configure and operate the unit
through the System Pilot user interface. A user interface is
not required for day-to-day operation. All maintenance,
configuration, setup, and diagnostic information is available through the Level II communications port to allow
data access by an attached computer running Network Service Tool or ComfortVIEW™ software.
→ Carrier linkage system compatibility
When linked to a Carrier Linkage System, the VVT zone
controller provides numerous features and benefits such as
weighted average demand for system operation, reference
zone temperature and set points, set point averaging, global set point schedule, and occupancy scheduling.
Additional control features
The VVT zone controller provides additional control features such as Occupied/Unoccupied scheduling initialized
via the network. The zone controller offers override
invoked from a wall sensor during unoccupied hours from
1 to 1440 minutes in 1-minute increments. Optional CO2
control or relative humidity monitoring are also available.
Simple actuator connection
The VVT zone controller control assembly contains an
integral VVT actuator assembly that is field mounted to the
terminal damper shaft, similar to the mounting of a standard actuator. The actuator is rated at 35 lb.-in. (3.95 N-m)
torque, a 90-degree stroke, and provides 90-second nominal timing at 60 Hz. The actuator is suitable for mounting
onto a 3/8-in. (9.5 mm) square or round VVT box damper
shaft, or onto a 1/2-in. (13 mm) round damper shaft.
The minimum VVT box damper shaft length is 13/4-in.
(45 mm). The VVT zone controller is designed for vertical
or horizontal mounting.
→ Ease of installation
The VVT zone controller is provided with removable connectors for power, communications, and damper. The
VVT zone controller has non-removable screw type connectors for inputs. The VVT zone controller also provides
an RJ-14 modular phone jack for the Carrier network
software connection to the module via Carrier network
communications.

PRODUCT DATA
Comfort Controller 6400
The Comfort Controller 6400 is a microcontroller-based
module that provides general purpose HVAC control
and monitoring capability in a standalone or network
environment using closed-loop, direct digital control.
The 6400 gives the Carrier Comfort Network (CCN) the
capability to control and communicate with non-Carrier
equipment and Carrier HVAC equipment not equipped
with Product Integrated Controls (PIC) controls.
You can connect 16 field points (8 inputs and 8 outputs)
to the 6400. To connect additional field points, add
optional input/output modules (8 inputs and 8 outputs
per I/O module) to the 6400. By using multiple I/O
modules, you can connect up to 48 additional points,
giving you the capability to control and/or monitor a total
of up to 64 field points. The appropriate number of I/O
modules are selected for each control situation and
simply installed along with the 6400 in your fieldselected NEMA-1 enclosure. This modular concept
contributes to overall versatility and ease of installation.
The Comfort Controller 6400 includes a diverse library
of performance-proven control routines, written in plain
English, using simple "fill-in-the blanks" format for fast,
easy programming. Additionally, for custom applications, Carrier's BEST++ software provides custom programming capabilities to work independently, or in
conjunction with the pre-engineered control routines.

Comfort Controller 6400-I/O
The Comfort Controller 6400-I/O is used with the Comfort Controller 6400 to expand the field point capacity
from 16 points (8 inputs and 8 outputs) up to a total of
64 points.
Each 6400-I/O can be configured to use all 16 points (8
inputs and 8 outputs) or only 8 outputs or only 8 inputs.
This provides the ultimate flexibility in useage of field
points to meet the specific needs of each application.
Determine the number of 6400-I/O required for your
particular application. Then simply install the modules
along with the 6400 in your field-selected NEMA-1
enclosure.
To determine the number of 6400-I/O required by the
particular application, first decide how many field points
are required. Then order and install the 6400-I/O(s)
along with the 6400 in your field-selected enclosure.
This modularity contributes to overall versatility.

• 33ZCT59SPT, space temperature sensor with LCD (liquid
crystal display) screen, override button, and set point
adjustment
If controlling an economizer in the thermostat mode, a duct
sensor must be mounted in the return air duct and wired to SPT
input.
SUPPLY AIR TEMPERATURE (SAT) SENSOR — The
PremierLink controller must be connected to a field-supplied
supply air temperature (SAT) sensor (part number
33ZCSENSAT) to monitor the temperature of the air delivered.
The SAT consists of a thermistor encased within a stainless
steel probe. The probe is 6 in. nominal length. The SAT sensor
has 114 in. of unshielded, plenum-rated cable (2 conductors,
22 AWG [American Wire Gage]). The sensor range is –40 to
185 F with a nominal resistance of 10,000 ohms at 77 F. The
sensor measures temperature with an accuracy of ±0.36 F.
Ideally, the SAT sensor should be located inside the unit
under the heat exchanger. The SAT sensor can also be installed
in the supply air duct downstream from unit heat source to
control.
INDOOR AIR QUALITY CO2 SENSOR — An indoor air
quality sensor is required for CO2 level monitoring. Three
different CO2 sensors are available for this application:
• 33ZCSENCO2 sensor is an indoor, wall-mounted sensor
with an LCD (liquid-crystal display) screen
• 33ZCT55CO2 sensor is an indoor, wall-mounted sensor
without display. The CO2 sensor also includes a space temperature sensor with override button
• 33ZCT56CO2 sensor is an indoor, wall-mounted sensor
without display. The CO2 sensor also includes a space temperature sensor with override button and temperature offset
OUTDOOR AIR QUALITY CO2 SENSOR — The
outdoor air CO2 sensor (33ZCSENCO2) is designed to monitor carbon dioxide (CO2) levels found in diesel exhaust and
control ventilation systems. It comes with an outdoor enclosure. This sensor provides an outdoor baseline for differential
DCV (Demand Control Ventilation) control.
NOTE: The relative humidity sensor and the outdoor air CO2
sensor cannot both be used on the controller at the same time.
RELATIVE HUMIDITY SENSOR — The 33ZCSENSRH01 relative space humidity sensor is required for dehumidification control on a rooftop unit equipped with a dehumidification
device. Otherwise, the relative humidity sensor is used for
monitoring only.
NOTE: The relative humidity sensor and the outdoor air CO2
sensor cannot both be used on the controller at the same time.
OUTDOOR AIR TEMPERATURE SENSOR — The
outdoor air temperature sensor (33ZCSENOAT) monitors the
temperature of the outside air. If the sensor is to be installed in
the outdoor air duct instead of an outdoor location, sensor
33ZCSENPAT should be used.
OUTDOOR AIR ENTHALPY SWITCH/RECEIVER
(33CSENTHSW) — This device measures both temperature
and humidity and converts the data into a relay output dependent on the sensor mode. Mode 1 is designed to energize the
relay at a fixed set point of 28 Btu/lb or 75 F. Mode 2 is used in
conjunction with the Return Air Enthalpy Sensor
(33CSENTSEN) to measure both indoor and outdoor enthalpy
and to determine which is greater. The enthalpy switch output
can be normally open or normally closed.
FILTER SWITCH — A field-supplied third-party differential
air flow switch with normally open contacts is requried for detection of dirty filters. The switch must be rated for a minimum
of 5 va at 24 vac.
GENERAL
The PremierLink™ controller, version 2.0, is a field retrofit
rooftop control compatible with the Carrier Comfort Network® (CCN) system. This control is designed to allow users
the access and ability to change factory-defined settings, thus
expanding the function of the standard unit control board. The
complete PremierLink package (part number 33CSPREMLK)
consists of a rooftop control circuit board with plastic cover
and label, wire harnesses, spade connectors, wire nuts and 4
mounting screws.
IMPORTANT: PremierLink part number 33CSPREMLK
should only be used in applications where the integrity
of the Underwriters Laboratories rating will be
maintained.
Access is available via an RJ-11 connection or a 3-wire connection to the communication bus. User interfaces available for
use with the CCN system are PCs equipped with Carrier user
interface software such as Service Tool, ComfortVIEW™, or
ComfortWORKS® software. When used as part of the CCN
system, other devices such as the CCN data transfer, System
Pilot™, Touch Pilot™, or Comfort Controller can read data
from or write data to the PremierLink retrofit controller.
INSTALLATION
Inspection — Inspect package contents for visual defects
that may have occurred during shipping. If there is any damage, contact your local representative before proceeding.
PremierLink Controller Hardware — The PremierLink package consists of the following hardware:
• control module (with plastic cover and label)
• 7 wire harnesses
• 10 spade connectors
• wire nuts
• 4 no. 6x1-in. self-drilling Phillips pan head mounting

unit. Be sure the location selected prevents moisture and
rain from coming into contact with the circuit board.
Select a location which will be safe from water damage and
allow sufficient access for service and wiring. For service
access, there should be at least 6 in. of clearance between the
front of the PremierLink controller and adjacent surfaces. Be
sure to leave 1/2-in. clearance in front of RJ-14 connector for
attaching RJ-14 cable from a CCN interface device. A fieldsupplied right angle 6-pin RJ-14 connector can be attached if
necessary.
NOTE: If the PremierLink controller must be installed in a
location where there is not easy access to CCN connectors,
a remote connection kit (part number 33CSREMCCN) can
be ordered.
MOUNTING — Refer to Mounting Sheet included with
controller for additional detailed mounting instructions.
1. Ensure all power to unit is removed.
2. Locate a space in the unit control panel or a space inside
the equipment that is free from dirt and dust.
3. Remove plastic cover by gently squeezing the middle of
longer sides of the cover and pull away from the board.

Install Sensors — The PremierLink™ controller can be
used with either the T58 communicating sensor or any combination of CO2 and space temperature sensors. Refer to the instructions supplied with each sensor for electrical requirements.
NOTE: All sensors are field-installed accessories.
SPACE TEMPERATURE (SPT) SENSOR INSTALLATION — There are four types of SPT sensors available from
Carrier: The 33ZCT55SPT space temperature sensor with
timed override button, the 33ZCT56SPT space temperature
sensor with timed override button and set point adjustment, the
33ZCT58SPT T58 communicating room sensor with timed
override button, set point adjustment, and manual fan control,
and the 33ZCT59SPT space temperature sensor with LCD
screen, override button, and set point adjustment.
The space temperature sensors are used to measure the
building interior temperature. The T58 communicating room
sensors measure and maintain room temperature by communicating with the controller. Sensors should be located on an
interior building wall. The sensor wall plate accommodates the
NEMA (National Electrical Manufacturers Association)
standard 2 x 4 junction box. The sensor can be mounted directly on the wall surface if acceptable by local codes.
Do not mount the sensor in drafty locations such as near air
conditioning or heating ducts, over heat sources such as baseboard heaters, radiators, or directly above wall-mounted lighting dimmers. Do not mount the sensor near a window which
may be opened, near a wall corner, or a door. Sensors mounted
in these areas will have inaccurate and erratic sensor readings.
The sensor should be mounted approximately 5 ft from the
floor, in an area representing the average temperature in the
space. Allow at least 4 ft between the sensor and any corner
and mount the sensor at least 2 ft from an open doorway. The
SPT sensor wires are to be connected to terminals in the unit
main control board.
Install the sensor as follows:
1. Locate the 2 Allen type screws at the bottom of the
sensor.
2. Turn the two screws clockwise to release the cover from
the sensor wall mounting plate.
3. Lift the cover from the bottom and then release it from
the top fasteners.
4. Feed the wires from the electrical box through the opening in the center of the sensor mounting plate.
5. Using two no. 6-32 x 1 mounting screws (provided with
the sensor), secure the sensor to the electrical box.
NOTE: Sensor may also be mounted directly on the
wall using 2 plastic anchors and 2 sheet metal screws
(field-supplied).
6. Use 20 gage wire to connect the sensor to the controller.
The wire is suitable for distances of up to 500 ft. Use a
three-conductor shielded cable for the sensor and set
point adjustment connections. The standard CCN
communication cable may be used. If the set point adjustment (slidebar) is not required, then an unshielded, 18 or
20 gage, two-conductor, twisted pair cable may be used.
The CCN network service jack requires a separate,
shielded CCN communication cable. Always use separate cables for CCN communication and sensor wiring. (Refer to Fig. 3-6 for wire terminations.)
7. Replace the cover by inserting the cover at the top of the
mounting plate first, then swing the cover down over the
lower portion. Rotate the 2 Allen head screws counterclockwise until the cover is secured to the mounting plate
and locked in position.

Perform the following steps to connect the SAT sensor to
the PremierLink™ controller:
1. Locate the opening in the control box. Pass the sensor
probe through the hole.
2. Drill or punch a 1/2-in. hole in the unit.
3. Use two field-supplied, self-drilling screws to secure the
sensor probe to the unit.
4. Connect the sensor leads to the PremierLink controller’s
wiring harness J6-3,4 board at the terminals labeled SAT
(ORN) and GND (BRN). See Fig. 7.
Perform the following steps if state or local code requires
the use of conduit, or if the installation requires a cable length
of more than 8 ft:
1. Secure the probe to the unit with two field-supplied
self-drilling screws.
2. If extending cable length beyond 8 ft, use plenum rated,
20 AWG, twisted pair wire.
3. Connect the sensor leads to the PremierLink controller’s
wiring harness terminal board at the terminals labeled
SAT (ORN) and GND (BRN).
4. Neatly bundle and secure excess wire.
SUPPLY AIR TEMPERATURE (SAT) SENSOR INSTALLATION — The 33ZCSENSAT supply air temperature sensor
is required for controller operation. The sensor consists of a
thermistor encased within a stainless steel probe. The SAT
sensor probe is 6-in. nominal length with 114 in. of unshielded,
2-conductor 18 AWG twisted-pair cables. The sensor temperature range is –40 to 245 F with a nominal resistance of
10,000 ohms at 77 F. The sensor measures accuracy of
±0.36 F. The SAT sensor is supplied with a gasket and 2 selfdrilling mounting screws.
NOTE: The sensor must be mounted in the discharge of the
unit, downstream of the cooling coil and heat exchanger. Be
sure the probe tip does not come in contact with any of the
unit surfaces. See Fig. 9 and 10 for mounting location.
Do not run sensor or relay wires in the same conduit or raceway with Class 1 AC service wiring. Do not abrade, cut, or
nick the outer jacket of the cable. Do not pull or draw cable
with a force that may harm the physical or electrical properties.
Avoid splices in any control wiring.

SUPPLY AIR
TEMPERATURE
SENSOR
Sensors use infrared technology to measure the levels of CO2
present in the air. The wall sensor is available with or without
an LCD readout to display the CO2 level in ppm.
The CO2 sensors are all factory set for a range of 0 to
2000 ppm and a linear mA output of 4 to 20. Refer to the
instructions supplied with the CO2 sensor for electrical requirements and terminal locations.
To accurately monitor the quality of the air in the conditioned air space, locate the sensor near a return-air grille (if
present) so it senses the concentration of CO2 leaving the
space. The sensor should be mounted in a location to avoid
direct breath contact.
Do not mount the IAQ sensor in drafty areas such as near
supply ducts, open windows, fans, or over heat sources. Allow
at least 3 ft between the sensor and any corner. Avoid mounting
the sensor where it is influenced by the supply air; the sensor
gives inaccurate readings if the supply air is blown directly onto
the sensor or if the supply air does not have a chance to mix
with the room air before it is drawn into the return airstream.
Wiring the Indoor Air Quality Sensor — To wire the sensors
after they are mounted in the conditioned air space or outdoor
location, see Fig. 7 and the instructions shipped with the sensors. For each sensor, use two 2-conductor 18 AWG (American
Wire Gage) twisted-pair cables (unshielded) to connect the separate isolated 24 vac power source to the sensor and to connect
the sensor to the control board terminals. To connect the sensor
to the control, identify the positive (4 to 20 mA) and ground
(SIG COM) terminals on the sensor. Connect the 4-20 mA terminal to terminal IAQ (RED) and connect the SIG COM terminal to terminal GND (BRN).
Combination Temperature and CO2 Sensor — If using a
combination temperature and CO2 sensor (33ZCT55CO2 or
33ZCT56CO2), refer to the installation instructions provided
with the sensor. See Fig. 11 for wiring.
OUTDOOR AIR QUALITY CO2 SENSOR INSTALLATION (OAQ) — The outdoor air CO2 sensor is designed to
monitor carbon dioxide (CO2) levels in the air and interface
with the ventilation damper in an HVAC system. The OAQ
sensor is packaged with an outdoor cover. See Fig. 12 and 13.
The outdoor air CO2 sensor must be placed in an area that is
representative of the entire conditioned space. A mounting
height of 6 ft is recommended. For installation where it is not
necessary to reach the control, it may be mounted higher on the
wall or on the ceiling, provided the location represents a good
sampling of air.
Wiring the Outdoor Air CO2 Sensor — Power requirements
are 18 to 36 VAC RMS 50/60 Hz; 18 to 42 vdc polarity
protected/dependent; and 70 mA average, 100 mA peak at
24 vdc. All system wiring must be in compliance with all
applicable local and national codes. A dedicated power supply
is required for this sensor. A two-wire cable is required to wire
the dedicated power supply for the sensor. The two wires
should be connected to the power supply and terminals 1 and 2.
To connect the sensor to the control, identify the positive (4 to
20 mA) and ground (SIG COM) terminals on the sensor. Connect the 4 to 20 mA terminal OAQ (BLU) terminal J5-2. Connect the SIG COM terminal to terminal GND (BRN) terminal
J5-3. See Fig. 11.

If the sensor is installed directly on a wall surface, install the
humidity sensor using 2 screws and 2 hollow wall anchors
(field-supplied). Do not over tighten screws. See Fig. 14.
The sensor must be mounted vertically on the wall. The
Carrier logo should be oriented correctly when the sensor is
properly mounted.
Avoid corner locations. Allow at least 4 ft between the sensor and any corner. Airflow near corners tends to be reduced,
resulting in erratic sensor readings. The sensor should be vertically mounted approximately 5 ft up from the floor, beside the
space temperature sensor.
For wiring distances up to 500 feet, use a 3-conductor, 18 or
20 AWG cable. A CCN communication cable can be used, although the shield is not required. The shield must be removed
from the sensor end of the cable if this cable is used. See
Fig. 15 for wiring details.
The power for the sensor is provided by the PremierLink
control on terminal J5-4 (+33 to +35vdc). To wire the sensor
perform the following:
1. At the sensor, remove 4-in. of jacket from the cable. Strip
1/ -in. of insulation from each conductor. Route the cable
4
through the wire clearance opening in the center of the
sensor. See Fig. 14.
2. Connect a field-supplied BLACK wire to the sensor
screw terminal marked Vin.
3. Connect a field-supplied RED wire into the sensor screw
terminal marked Io.
4. At the PremierLink controller, route the cable away from
high voltage wiring and disconnect the power to prevent
accidental shorting or grounding of wires when connecting the sensor. Remove the J5 Molex female plug and locate the BROWN wire on pin 3. Using a small, flat blade
screwdriver gently press down in the slot on the side of
the plug while pulling on the BROWN wire to remove it
from slot. Re-insert the BROWN wire in the pin 4 slot
making sure it is securely seated. There should now be an
empty slot between the BLUE and BROWN wires. See
Fig. 15.
5. Connect the field-supplied RED wire from the sensor to
the BLUE wire on J5-4.
6. Connect the field-supplied BLACK wire from the sensor
to the BROWN wire on J5-2.

OUTDOOR AIR TEMPERATURE SENSOR (Fig. 16-19) —
The OAT sensor must be located properly. For outdoor locations use sensor 33ZCSENOAT. For duct mounting in the
fresh air intake, use sensor 33ZCSENPAT. The sensor must be
installed immediately upstream from outdoor-air damper
where it will accurately sense the temperature of the outdoor
air entering the mixing box. See Fig. 16 and 17. For applications without economizer, the sensor may be located in the outdoor air duct near the outdoor-air intake (Fig. 17) or on the
exterior of the building (Fig. 16). The thermistor has a range of
–40 to 245 F and a resistance of 10,000 ohms at 77 F.
Do not mount the sensor in direct sunlight. Inaccurate readings may result. Do not mount the sensor near the exhaust from
air-handling units or compressors, near leakage drafts of indoor
air, or near shrubbery or trees, or under direct water runoff.
If the sensor is installed outdoors, perform the following instructions. Install the 1/2-in. conduit connector into the rear
opening. Tighten the conduit connector securely to prevent
water leakage into the assembly. Mount the assembly onto the
1/ -in. conduit and secure by tightening the conduit nut. After
2
the sensor wiring is completed, secure the gasket and cover in
place using the screws provided with the cover. See Fig. 18.
If the sensor is to be mounted in the outdoor air duct, use the
33ZCSENPAT sensor which has a 2 x 4-in. by 11/2-in. deep
electrical box. Remove the cover and enter the knockout from
the rear of the box. Install the sensor through the opening so
that the sensor leads are inside the electrical box. Secure the
sensor to the electrical box using a field-supplied 1/2-in. conduit nut. Drill a 1/2-in. hole in the outdoor-air duct about a foot
upstream of the outdoor-air damper. Apply a 1/4-in. bead of silicone type sealer around the opening and install the sensor
through the hole. Secure the electrical box to the duct using 2
field-supplied, no. 10 sheet metal screws. See Fig. 19.
FACTORY-INSTALLED CONTROLLER — The PremierLink™ controller is available as a factory-installed option on
some units. Additional terminal boards are provided for wiring.
Sensors and input devices are wired to terminal boards instead
of directly to the Premierlink controller. See Fig. 20.
Connect Discrete Inputs — If used, wire the dry con-
tact switches, compressor safety switch, and supply fan status
switch to the PremierLink controller. See Fig. 21 for wiring.

Connect to CCN Communication Bus — The
PremierLink™ controller connects to the bus in a daisy chain
arrangement. Negative pins on each component must be
connected to respective negative pins, and likewise, positive
pins on each component must be connected to respective positive pins. The controller signal pins must be wired to the signal
ground pins. Wiring connections for CCN must be made at the
3-pin plug.
At any baud (9600, 19200, 38400 baud), the number of controllers is limited to 239 devices maximum. Bus length may not
exceed 4000 ft, with no more than 60 total devices on any
1000-ft section. Optically isolated RS-485 repeaters are
required every 1000 ft.
NOTE: Carrier device default is 9600 band.
COMMUNICATION BUS WIRE SPECIFICATIONS —
The CCN Communication Bus wiring is field-supplied and
field-installed. It consists of shielded 3-conductor cable with
drain (ground) wire. The cable selected must be identical to the
CCN Communication Bus wire used for the entire network.

insulated with PVC, PVC/nylon, vinyl, Teflon, or polyethylene. An aluminum/polyester 100% foil shield and an outer
jacket of PVC, PVC/nylon, chrome vinyl, or Teflon with a
minimum operating temperature range of –20 C to 60 C is
required. Do not run communication wire in the same conduit
as or next to any AC voltage wiring.
The communication bus shields must be tied together at
each system element. If the communication bus is entirely
within one building, the resulting continuous shield must be
connected to ground at only one single point. If the communication bus cable exits from one building and enters another
building, the shields must be connected to the grounds at a
lightning suppressor in each building (one point only).

a33-9137
OUTDOOR ENTHALPY CONTROL (Fig. 24) — Outdoor
enthalpy control requires only an enthalpy switch/receiver
(33CSENTHSW). The enthalpy switch/receiver is mounted in
the outdoor air inlet and calculates outdoor air enthalpy. The
enthalpy switch/receiver energizes the relay output when the
outdoor enthalpy is above 28 BTU/lb OR dry bulb temperature is above 75 F and is deenergized when the outdoor
enthalpy is below 27 BTU/lb AND dry bulb temperature is
below 74.5 F. The relay output is wired to the unit economizer
which will open or close depending on the output of the
switch.
NOTE: The enthalpy calculation is done using an average altitude of 1000 ft above sea level.
Mounting — Mount the enthalpy switch/receiver in a location
where the outdoor air can be sampled (such as the outdoor air
intake). The enthalpy switch/receiver is not a NEMA 4 enclosure and should be mounted in a location that is not exposed to
outdoor elements such as rain or snow. Use two field-supplied
no. 8 x 3/4-in. TEK screws. Insert the screws through the holes
in the sides of the enthalpy switch/receiver.
Wiring — Carrier recommends the use of 18 to 22 AWG
twisted pair or shielded cable for all wiring. All connections
must be made with 1/4-in. female spade connectors.
A 24-vac transformer is required to power the enthalpy
switch/receiver; as shown in Fig. 24, the PremierLink™ board
provides 24 vac. Connect the GND and 24-vac terminals on the
enthalpy switch/receiver to the terminals on the transformer.
On some applications, the power from the economizer harness
can be used to power the enthalpy switch/receiver. To power
the enthalpy switch/receiver from the economizer harness, connect power of the enthalpy switch/receiver to the red and
brown wires (1 and 4) on the economizer harness.
For connection to rooftop units with PremierLink™ control,
connect the LOW Enthalpy terminal on the enthalpy switch/receiver to J4 — pin 2 of the PremierLink control on the HVAC
(Heating, Ventilation, and Air Conditioning) unit. The switch
can be powered through the PremierLink control board if desired. Wire the 24-vac terminal on the enthalpy switch/receiver
to J4 — pin 1 on the PremierLink control. Wire the GND terminal on the enthalpy switch/receiver to J1 — pin 2 on the PremierLink control. The HI Enthalpy terminal is not used. See
Fig. 24.
DIFFERENTIAL ENTHALPY CONTROL (Fig. 25) —
Differential enthalpy control requires both an enthalpy switch/
receiver (33CSENTHSW) and an enthalpy sensor
(33CSENTSEN). The enthalpy switch/receiver is mounted in
the outdoor air inlet and calculates outdoor air enthalpy. The
enthalpy sensor is mounted in the return airstream and calculates the enthalpy of the indoor air.
The enthalpy switch/receiver energizes the HI Enthalpy relay output when the outdoor enthalpy is greater than the indoor
enthalpy. The LOW Enthalpy terminal is energized when the
outdoor enthalpy is lower than the indoor enthalpy. The relay
output is wired to the unit economizer which will open or close
depending on the output of the switch.
NOTE: The enthalpy calculation is done using an average altitude of 1000 ft above sea level.
Mounting — Mount the enthalpy switch/receiver in a location
where the outdoor air can be sampled (such as the outdoor air
intake). The enthalpy switch/receiver is not a NEMA 4 enclosure and should be mounted in a location that is not exposed to
outdoor elements such as rain, snow, or direct sunlight. Use
two field-supplied no. 8 x 3/4-in. TEK screws. Insert the screws
through the holes in the sides of the enthalpy switch/receiver.
Enthalpy Switch/Receiver — The accessory en-
thalpy switch/receiver (33CSENTHSW) senses temperature
and humidity of the air surrounding the device and calculates
the enthalpy when used without an enthalpy sensor. The relay is
energized when enthalpy is high and deenergized when enthalpy is low (based on ASHRAE [American Society of Heating, Refrigeration, and Air Conditioning Engineers] 90.1 criteria). If an accessory enthalpy sensor (33CSENTSEN) is attached to the return air sensor input, then differential enthalpy is
calculated. The relay is energized when the enthalpy detected by
the return air enthalpy sensor is less than the enthalpy at the enthalpy switch/receiver. The relay is deenergized when the enthalpy detected by the return air enthalpy sensor is greater than
the enthalpy at the enthalpy switch/receiver (differential enthalpy control). See Fig. 22 and 23.

JUMPER SETTINGS FOR 33CSENTSEN
Mount the enthalpy sensor in a location where the indoor air
can be sampled (such as the return air duct). The enthalpy
sensor is not a NEMA 4 enclosure and should be mounted in a
location that is not exposed to outdoor elements such as rain or
snow. Use two field-supplied no. 8 x 3/4-in. TEK screws. Insert
the screws through the holes in the sides of the enthalpy sensor.
Wiring — Carrier recommends the use of 18 to 22 AWG
twisted pair or shielded cable for all wiring. All connections
must be made with 1/4-in. female spade connectors.
The PremierLink™ board provides 24-vac to power the enthalpy switch/receiver. Connect the GND and 24-vac terminals
on the enthalpy switch/receiver to the terminals on the transformer. On some applications, the power from the economizer
harness can be used to power the enthalpy switch/receiver. To
power the enthalpy switch/receiver from the economizer harness, connect power of the enthalpy switch/receiver to the red
and brown wires (1 and 4) on the economizer harness.
Connect the LOW Enthalpy terminal on the enthalpy
switch/receiver to J4 — pin 2 of the PremierLink control on the
HVAC unit. The switch can be powered through the PremierLink control board if desired. Wire the 24 vac terminal on the
enthalpy switch/receiver to J4 — pin 1 on the PremierLink
control. Wire the GND terminal on the enthalpy switch/
receiver to J1 — pin 2 on the PremierLink control. The HI
Enthalpy terminal is not used. See Fig. 24.
Connect the 4-20 mA In terminal on the enthalpy switch/
receiver to the 4-20 mA Out terminal on the return air enthalpy
sensor. Connect the 24-36 VDC Out terminal on the enthalpy
switch/receiver to the 24-36 VDC In terminal on the return air
enthalpy sensor. See Fig. 25.
Enthalpy Switch/Receiver Jumper Settings — There are two
jumpers. One jumper determines the mode of the enthalpy
switch/receiver. The other jumper is not used. To access the
jumpers, remove the 4 screws holding the cover on the enthalpy switch/receiver and then remove the cover. The factory
settings for the jumpers are M1 and OFF.
The mode jumper should be set to M2 for differential enthalpy control. The factory test jumper should remain on OFF
or the enthalpy switch/receiver will not calculate enthalpy.
Enthalpy Sensor Jumper Settings — There are two jumpers.
One jumper determines the mode of the enthalpy sensor. The
other jumper is not used. To access the jumpers, remove the
4 screws holding the cover on the enthalpy sensor and then
remove the cover. The factory settings for the jumpers are M3
and OFF.
The mode jumper should be set to M3 for 4 to 20 mA
output. The factory test jumper should remain on OFF or the
enthalpy sensor will not calculate enthalpy.

OUTDOOR AIR ENTHALPY SENSOR/ENTHALPY
CONTROLLER (HH57AC077) — To wire the outdoor air
enthalpy sensor, perform the following (see Fig. 28 and 29):
NOTE: The outdoor air sensor can be removed from the back
of the enthalpy controller and mounted remotely.
1. Use a 4-conductor, 18 or 20 AWG cable to connect the
enthalpy control to the PremierLink controller and power
transformer.
2. Connnect the following 4 wires from the wire harness
located in rooftop unit to the enthalpy controller:
a. Connect the BRN wire to the 24 vac terminal
(TR1) on enthalpy control and to pin 1 on 12-pin
harness.
b. Connect the RED wire to the 24 vac GND terminal
(TR) on enthalpy sensor and to pin 4 on 12-pin
harness.
c. Connect the ORN/GRAY wire to J4-2 on PremierLink controller and to terminal (3) on enthalpy sensor.
d. Connect the RED/GRAY wire to J4-1 on PremierLink controller and to terminal (2) on enthalpy sensor.
Enthalpy Sensors and Control — The enthalpy
control (HH57AC077) is supplied as a field-installed accessory
to be used with the economizer damper control option. The
outdoor air enthalpy sensor is part of the enthalpy control. The
separate field-installed accessory return air enthalpy sensor
(HH58AC078) is required for differential enthalpy control. See
Fig. 26.
NOTE: The enthalpy control must be set to the “D” setting
for differential enthalpy control to work properly.
The enthalpy control receives the indoor and return
enthalpy from the outdoor and return air enthalpy sensors
and provides a dry contact switch input to the PremierLink
controller. Locate the controller in place of an existing
economizer controller or near the actuator. The mounting plate
may not be needed if existing bracket is used. See Fig. 27.
A closed contact indicates that outside air is preferred to the
return air. An open contact indicates that the economizer
should remain at minimum position.
20
This condition is followed by a constant 36 VDC output from
the PremierLink economizer output (J-9).
NOTE: If installing in a Carrier rooftop, use the two gray
wires provided from the control section to the economizer
to connect PremierLink™ controller to terminals 2 and 3 on
enthalpy sensor. If NOT using Carrier equipment, wires
may need to be field supplied and installed.
RETURN AIR ENTHALPY SENSOR — Mount the returnair enthalpy sensor (HH57AC078) in the return-air duct. The
return air sesnor is wired to the enthalpy controller
(HH57AC077). See Fig. 26. The outdoor enthalpy changeover
set point is set at the controller.
To wire the return air enthalpy sensor, perform the following (see Fig. 28):
1. Use a 2-conductor, 18 or 20 AWG, twisted pair cable to
connect the return air enthalpy sensor to the enthalpy
controller.
2. At the enthalpy control remove the factory-installed resistor from the (SR) and (+) terminals.
3. Connect the field-supplied RED wire to (+) spade
connector on the return air enthalpy sensor and the (SR+)
terminal on the enthalpy controller. Connect the BLK
wire to (S) spade connector on the return air enthalpy
sensor and the (SR) terminal on the enthalpy controller.

IMPORTANT: It is recommended that the Q769C adapter
be used with a field-supplied 500-ohm resistor across the
terminals.
Using the Q769C and actuator requires a separate, fieldsupplied transformer because the actuator with a Q769C is
a positive ground device. The PremierLink control is a negative ground device.

with an economizer in some applications. Most common economizers will contain a Honeywell actuator (Honeywell part
number M7415).
An adapter (Honeywell part number Q769B or Q769C)
must be used to enable the 4 to 20 mA signal from the PremierLink controller to control the position of the economizer. Refer
to Honeywell Q769B and Q769C accessory installation
instructions for wiring details.
Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage.
Q769B ADAPTER — Because the Honeywell adapter is designed for a negative 4 to 20 mA input instead of a positive signal, the Q769B adapter requires a separate transformer and a
current loop isolator to perform properly. Connecting the
adapter directly to the PremierLink controller could cause the 4
to 20 mA output on the controller to be permanently damaged.

If Reverse Acting (RA) operation is desired, move Switch 3
to the RA position. An increasing control signal drives the
actuator toward the spring return position in RA mode.
SWITCH SELECTION — The type of input control signal is
determined by the position of Switch 5. With Switch 5 in the
VDC position (factory setting), the signal is DC voltage. With
Switch 5 min the mA position, the input signal changes to
current input. See Fig. 32 and Table 6. The switch should be set
to mA for use with PremierLink controller.
NOTE: To change the factory setting, use a 1/8-in. (3-mm)
flat-blade screwdriver to position the mode switch to the alternate setting.

provided in the 12-pin harness that is standard on all Carrier
equipment. To connect the economizer actuator (installed on
Bellimo or Johnson Controls actuators) to PremierLink controller, connect the pink wire on actuator to purple wire on PremierLink J9-1. See Fig. 34A and 34B.
NOTE: To retrofit PremierLink controller to older 4 to 20 mA
actuator, connect the red wire on the actuator wire harness to
the purple wire on the PremierLink J9-1. Connect the yellow
and white wires from the actuator wire harness to the 24-volt
AC transformer on equipment. See Fig. 33.

The economizer features a Johnson 4 to 20 mA actuator.
IMPORTANT: The actuator that comes with the economizer is a stepper-type actuator and is NOT compatible
with PremierLink control. This actuator should be replaced
with a 4 to 20 mA actuator.
DRIVE DIRECTION — The actuator drive direction is
dependent upon the position of Switch 3 and the spring return
direction. See Table 5. The actuator is factory set for Direct
Acting (DA) operation with Switch 3 in the DA position. An
increasing control signal drives the actuator away from the
spring return position in DA mode. The actuator should be

for both the PremierLink power and the actuator power.
This is especially important if separate transformers are
used.

connected to the CCN bus.
START-UP
Initial Operation and Test — Perform the following
procedure:
1. Apply 24 vac power to the control.
2. Connect the service tool to the phone jack service port of
the controller.
3. Using the Service Tool, upload the controller from
address 0, 31 at 9600 baud rate. The address may be set at
this time. Make sure that Service Tool is connected to
only one unit when changing the address.
MEMORY RESET — DIP switch 4 causes an E-squared
memory reset to factory defaults after the switch has been
moved from position 0 to position 1 and the power has been
restored. To enable the feature again, the switch must be put
back to the 0 position and power must be restored; this prevents subsequent resets to factory defaults if the switch is left
at position 1.
To cause a reset of the non-volatile memory (to factory
defaults), turn the controller power off if it is on, move the
switch from position 1 to position 0, and then apply power to
the controller for a minimum of 5 seconds. At this point, no
action occurs, but the controller is now ready for the memory
to reset. Remove power to the controller again and move the
switch from position 0 to position 1. This time, when power is
applied, the memory will reset to factory defaults. The controller address will return to bus 0 element 31, indicating that
memory reset occurred.
The unit must be electrically grounded in accordance with
local codes and NEC ANSI/NFPA 70 (American National
Standards Institute/National Fire Protection Association).
Use the Carrier network communication software to start up
and configure the PremierLink controller.
Changes can be made using the ComfortWORKS® software, ComfortVIEW™ software, Network Service Tool, System Pilot™ device, or Touch Pilot™ device. The System Pilot
and Touch Pilot are portable interface devices that allow the
user to change system set-up and set points from a zone sensor
or terminal control module. During start-up, the Carrier software can also be used to verify communication with PremierLink controller.
NOTE: All set-up and set point configurations are factoryset and field-adjustable.
For specific operating instructions, refer to the literature
provided with user interface software.
Perform System Check-Out
1. Check correctness and tightness of all power and
communication connections.
2. At the unit, check fan and system controls for proper
operation.
3. At the unit, check electrical system and connections of
any optional electric reheat coil.
4. Check to be sure the area around the unit is clear of
construction dirt and debris.
5. Check that final filters are installed in the unit. Dust and
debris can adversely affect system operation.
Sequence of Operation
THERMOSTAT MODE — If the PremierLink™ controller is
configured for Thermostat mode (TSTAT), it will control only
to the thermostat inputs on J4. These inputs can be overridden
through CCN communication via the CV_TSTAT points display table. When in this mode, the fire safety shutdown (FSD)
25
SASP after the stage two has been on for 90 seconds. This provides protection for the compressor against flooded starts and
allow refrigerant flow to stabilize before modulating the economizer again. By using return air across the evaporator coil just
after the compressor has started allows for increased refrigerant
flow rates providing better oil return of any oil washed out during compressor start-up.
Routine No. 3: If the OAT > 68 F and the enthalpy is low
and the OAT <SPT then the economizer will open to 100% and
compressors 1 and 2 will be cycled based on Y1 and Y2 inputs
respectively. If any of these conditions are not met the economizer will go to minimum position.
If there is no call for heating or cooling, the economizer, if
available, will maintain the SASP at 70 F.
Heating — For gas or electric heat, HS1 and HS2 outputs will
follow W1 and W2 inputs respectively. The fan will also be
turned on if it is configured for electric heat.
If the PremierLink controller is configured for heat pump
operation with the Auxiliary Out relay for Reversing Valve
(AUXOUT = 3 in the CONFIG configuration table), the indoor
fan will be turned on, compressors 1 and 2 turned on and the
reversing valve relay (HS3) will be energized on a call from the
W1 input. On a call from the W2 input, heat outputs HS1 and
HS2 will be energized. If only W2 input is detected, then it will
be determined as call for emergency heat and HS1 and HS2
will be energized. The reversing valve relay will stay energized
until there is a call for cooling at which time it will be
deenergized.
Heating may also be energized when an IAQ sensor installed and has overridden the minimum economizer damper
position. If the OAT < 55 F and an IAQ sensor is installed and
the IAQ minimum position > minimum damper position
causing the SAT to decrease below the SPT – 10° F, then the
heat stages will be cycled to temper the SAT to maintain a temperature between the SPT and the SPT + 10° F.
Auxiliary Relay configured for Exhaust Fan — If the Auxiliary Relay is configured for exhaust fan (AUXOUT = 1) in the
CONFIG configuration table and Continuous Power Exhaust
(MODPE) is enable in the SERVICE configuration table then
the output (HS3) will be energized whenever the G input is on.
If the MODPE is disabled then output will be energized based
on the Power Exhaust Setpoint (PES) in the SETPOINT table.
Indoor Air Quality — If the optional indoor air quality (IAQI)
sensor is installed, the PremierLink™ controller will maintain
indoor air quality within the space at the user-configured differential set point (IAQD) in the CONFIG configuration table.
The set point is the difference between the IAQI and an optional outdoor air quality sensor (OAQ). If the OAQ is not present
then a fixed value of 400 ppm is used. The actual space IAQ
setpoint (IAQS) is calculated as follows:
IAQS = IAQD + OAQ (OAQ = 400 ppm if not present)
As air quality within the space changes, the minimum position of the economizer damper will be changed also thus allowing more or less outdoor air into the space depending on the relationship of the IAQI to the IAQS. The IAQ algorithm runs
every 30 seconds and calculates IAQ minimum position value
using a PID loop on the IAQI deviation from the IAQS. The
IAQ minimum position is then compared against the user configured minimum position (MDP) and the greatest value becomes the final minimum damper position (IQMP). If the calculated IAQ Minimum Position is greater than the IAQ maximum damper position (IAQMAXP) decision in the SERVICE
configuration table, then it will be clamped to IAQMAXP
value.
If IAQ is configured for low priority, the positioning of the
economizer damper can be overridden by comfort requirements. If the SAT < SASP – 8°F and both stages of heat are on
for more then 4 minutes or the SAT > SASP + 5° F and both
stages of cooling on for more then 4 minutes then the IAQ
input cannot be used, so any fire/life safety shutdown must be
physically wired to disable the 24 vac control circuit to the unit.
Indoor Fan — The indoor fan output will be energized whenever there is 24 vac present on the G input. The indoor fan will
be turned on without any delay and the economizer damper
will open to its minimum position if the unit has a damper connected to the controller. This will also occur if the PremierLink™ controller has been configured for electric heat or heat
pump operation.
Cooling — For cooling operation, there must be 24 vac present
on G. When G is active, the PremierLink controller will then
determine if outdoor conditions are suitable for economizer
cooling when an economizer damper is available. A valid OAT,
SPT (CCN space temperature) and SAT (supply air temperature) sensor MUST be installed for proper economizer operation. It recommended that an outdoor or differential enthalpy
sensor also be installed. If one is not present, then a jumper is
needed on the ENTH input on J4, which will indicate that the
enthalpy will always be low. Economizer operation will be
based only on outdoor air dry bulb temperature. The conditions
are suitable when: enthalpy is low, OAT is less than OATL
High Lockout for TSTAT, and OAT is less than OATMAX, the
high set point for free cooling. The default for OATL is 65 F.
The default for OATMAX is 75 F.
When all of the above conditions are satisfied and all the required sensors are installed, the PremierLink controller will use
the economizer for cooling. One of three different control routines will be used depending on the temperature of the outside
air. The routines use a PID loop to control the SAT to a supply
air set point (SASP) based on the error from set point (SASPSAT). The SASP is determined by the routine.
If an economizer is not available or the conditions are not
met for the following economizer routines below, the
compressors 1 and 2 will be cycled based on Y1 and Y2 inputs
respectively.
Any time the compressors are running, the PremierLink
controller will lock out the compressors if the SAT becomes
too low. These user configurable settings are found in the SERVICE configuration table:
Compressor 1 Lockout at SAT < SATLO1 (50 to 65 F) (default is 55 F)
Compressor 2 Lockout at SAT < SATLO2 (45 to 55 F) (default is 50 F)
After a compressor is locked out, it may be started again after a normal time-guard period and the supply-air temperature
has increased at least 8° F above the lockout set point.
Routine No. 1: If the OAT ≤ DXLOCK (OAT DX lockout
temperature) and DX Cooling Lockout is enabled when Y1 input is energized, the economizer will be modulated to maintain
SAT at the Supply Air Setpoint (SASP) = SATLO1 + 3° F
(Supply Air Low Temp lockout for compressor 1). When Y2
is energized, the economizer will be modulated to control to a
lower SASP = SATLO2 + 3° F (Supply Air Low Temp lockout
for compressor no. 2). Mechanical cooling is locked out and
will not be energized.
Routine No. 2: If DXLOCK (or DX Cooling Lockout is
disabled) < OAT ≤ 68 F when Y1 input is energized, the economizer will be modulated to maintain SAT at SASP = SATLO1
+ 3° F. If the SAT > SASP + 5° F and the economizer position
> 85% then the economizer will close the to minimum position
for three minutes or until the SAT > 68 F. The economizer integrator will then be reset and begin modulating to maintain the
SASP after stage one has been energized for 90 seconds.
When Y2 is energized, the economizer will be modulated to
control to a lower supply air setpoint SASP= SATLO2 + 3° F.
If the SAT > SASP + 5° F it will close the economizer to minimum position for 3 minutes, reset the integrator for the economizer, then start modulating the economizer to maintain the
26
The PremierLink controller has an optional Supply Fan Status input to provide proof of airflow. If this is enabled, the point
will look for a contact closure whenever the Supply Fan Relay
is on. If the input is not enabled, then it will always be the
same state as the Supply Fan Relay. The cooling, economizer
and heating routines will use this input point for fan status.
Cooling — The compressors are controlled by the Cooling
Control Loop that is used to calculate the desired SAT needed
to satisfy the space. It will compare the SPT to the Occupied
Cool Setpoint (OCSP) + the T56 slider offset (STO) when occupied and the Unoccupied Cool Setpoint (UCSP + Unoccupied Cooling Deadband) if unoccupied to calculate a Cooling
Submaster Reference (CCSR) that is then used by the staging
algorithm (Cooling submaster loop) to calculate the required
number of cooling stages. The economizer, if available, will be
used as the first stage of cooling in addition to the compressors.
This loop runs every minute. The following conditions must be
met in order for this algorithm to run:
• indoor fan has been ON for at least 30 seconds
• heat mode is not active and the time guard between modes
equals zero.
• mode is occupied or the Temperature Compensated Start or
Cool mode is active
• SPT reading is available and > (OCSP + STO)
• If mode is unoccupied and the SPT > (UCSP + Unoccupied
Cooling Deadband). The indoor fan will be turned on by the
staging algorithm.
• OAT > DXLOCK or OAT DX Lockout is disabled
If all of the above conditions are met, the CCSR will be calculated, otherwise it is set to its maximum value and DX stages
is set to 0. If only the last condition is not true and an economizer is available, it will be used to cool the space.
The submaster loop uses the CCSR compared to the actual
SAT to determine the required number of capacity stages to satisfy the load. There is a programmable minimum internal time
delay of 3 to 5 minutes on and 2 to 5 minutes off for the compressors to prevent short cycling. There is also a 3-minute time
delay before bringing on the second stage compressor. If the
PremierLink controller is configured for Heat Pump and AUXOUT is configured for Reversing Valve Cool, the H3_EX_RV
ouput will energize 2 seconds after the first compressor is energized and stay energized until there is a demand for heat. If
AUXOUT is configured for Reversing Valve Heat, then the
H3_EX_RV contact will be deenergized when there is a demand for cooling. An internal 5 to 10-minute user-programmable time guard between modes prevents rapid cycling between
modes when used in a single zone application. The Time Guard
is lowered to 3 minutes when Linkage is active to allow the
3V™ linkage coordinator to have better control of the PremierLink controller when used as the air source for the 3V control
system.
Table 7 indicates the number of stages available. The staging algorithm looks at the number of stages available based the
number of cool stages configured in the SERVICE configuration table. The algorithm will skip the economizer if it is not
available and turn on a compressor.
Any time the compressors are running, the PremierLink
controller will lockout the compressors if the SAT becomes too
low. These user configurable settings are found in the SERVICE configuration table:
Compressor 1 Lockout at SAT < SATLO1 (50 to 65 F) (default is 55 F)
Compressor 2 Lockout at SAT < SATLO2 (45 to 55 F) (default is 50 F)
After a compressor is locked out, it may be started again after a normal time-guard period and the supply air temperature
has increased at least 8° F above the lockout set point.
minimum damper position will become 0 and the IQMP =
MDP. IAQ mode will resume when the SAT > SASP – 8° F in
heating or the SAT < SASP + 5° F in cooling. If the PremierLink™ controller is configured for 1 stage of heat and cool or
is only using a single stage thermostat input, this function will
not work as it requires the both Y1 and Y2 or W1 and W2 inputs to be active. In this application, it is recommended that the
user configure IAQ priority for high.
If IAQ is configured for high priority and the OAT < 55 F
and the SAT < (SPT –10° F), the algorithm will enable the heat
stages to maintain the SAT between the SPT and the SPT +
10° F.
CCN SENSOR MODE — When the PremierLink controller
is configured for CCN control, it will control the compressor,
economizer and heating outputs based its own space temperature input and set points or those received from Linkage. An
optional CO2 IAQ sensor mounted in the space or received
through communications can also influence the economizer
and heating outputs. The PremierLink controller does not have
a hardware clock so it must have another device on the CCN
communication bus broadcasting time. The controller will
maintain its own time once it has received time as long as it has
power and will send a request for time once a minute until it receives time when it has lost power and power is restored. The
controller will control to unoccupied set points until it has received a valid time. The controller must have valid time in order to perform any broadcast function, follow an occupancy
schedule, perform IAQ pre-occupancy purge and many other
functions as well. The following sections describe the operation for the functions of the PremierLink controller.
Indoor Fan — The indoor fan will be turned on whenever any
one of the following conditions are met:
• If the PremierLink controller is in the occupied mode and
ASHRAE 90.1 Supply Fan is configured for Yes in the
CONFIG table. This will be determined by its own internal
occupancy schedule if it is programmed to follow its local
schedule or broadcast its local schedule as a global schedule, or following a global schedule broadcast by another
device.
• If PremierLink controller is in the occupied mode and
ASHRAE 90.1 Supply Fan is configured for No and there is
a heat or cool demand (fan auto mode)
• If the PremierLink controller is in the occupied mode and
ASHRAE 90.1 Supply Fan is configured for Yes when
Linkage is active and the Linkage Coordinator device is
sending an occupied mode flag
• When Temperature Compensated Start is active
• When Free Cool is active
• When Pre-Occupancy Purge is active
• Whenever there is a demand for cooling or heating in the
unoccupied mode
• Whenever the Remote Contact input is configured for
Remote Contact (RC_DC=1 in SERVICE table) and it is
closed or the point is forced Closed via communications in
the STATUS01 points display table (remote contact closed
= occupied, remote contact open = unoccupied)
• Whenever the H3_EX_RV point is configured for Dehumidification (AUXOUT=5 in CONFIG table) and it is in
the unoccupied mode and the indoor RH exceeds the unoccupied humidity set point
• Whenever the Supply Fan Relay point is forced On in the
STATUS01 points display table
The fan will also continue to run as long as compressors are
on when transitioning from occupied to unoccupied with the
exception of Fire Shutdown mode. If the Fire Shutdown input
point is closed or forced in the STATUS01 points display table,
the fan will be shutdown immediately regardless of the occupancy state or demand.
27
consideration to avoid large changes in damper position when
the OAT is cold:
ECONPOS = SubGain x (ECONSR–SAT) + CTRVAL
where SubGain = (OAT – TEMPBAND) / (ESG + 1)
If the OAT < DXLOCK (DX Cool Lockout set point) then
the damper will be modulated to maintain the SAT at the
ECONSR value.
If the OAT is between DXLOCK and 68 F (DXLOCK <
OAT < 68 F) and additional cooling is required, the economizer
will close the to minimum position for three minutes, the
economizer integrator will then be reset to 0 and begin modulating to maintain the SASP after the stage has been energized
for about 90 seconds. This will allow the economizer to calculate a new ECONSR that takes into account the cooling effect
that has just been turned on and not return to the value require
before the cooling was added. This will prevent the economizer from causing premature off cycles of compressors while
maintaining the low SAT temperature set point for the number
of stages active. In addition to preventing compressor short cycling, by using return air across the evaporator coil just after the
compressor has started allows for increased refrigerant flow
rates providing for better oil return of any oil washed out during compressor start-up.
If the OAT > 68 F and OAT < SPT and the number of DX
stages requested is > 0 by the staging algorithm, then ECONSR
is set to its minimum value 48 F and the damper will go to
100% open.
If the Auxiliary Relay is configured for exhaust fan (AUXOUT = 1) in the CONFIG configuration table and Continuous
Power Exhaust (MODPE) is Enable in the SERVICE configuration table, then the AUXO output (HS3) will be energized
whenever the PremierLink controller is in the occupied mode.
If the MODPE is disabled then AUXO output will be energized
based on the Power Exhaust Setpoint (PES) in the SETPOINT
table.
Heating — The heat stages are controlled by the Heating Control Loop, which is used to calculate the desired SAT needed to
satisfy the space. It will compare the SPT to the Occupied Heat
Setpoint (OHSP) + the T56 slider offset (STO) when occupied
and the Unoccupied Heat Setpoint (UHSP – Unoccupied Heating Deadband) if unoccupied to calculate a Staged Heat Submaster Reference (SHSR). The heat staging algorithm compares the SHSR to the actual SAT to calculate the required
number of heating stages to satisfy the load. This loop runs every 40 seconds. The following conditions must be met in order
for this algorithm to run:
• Indoor fan has been ON for at least 30 seconds.
• Cool mode is not active and the time guard between modes
equals zero.
• Mode is occupied or the Temperature Compensated Start or
Heat mode is active.
• SPT reading is available and < (OHSP + STO).
• If it is unoccupied and the SPT < (UHSP – Unoccupied
Heating Deadband). The indoor fan will be turn on by the
staging algorithm.
When all of the above conditions are met, the SHSR is calculated and up to 3 stages of heat will turned on and off to satisfy to maintain the SAT = SHSR. If any of the above conditions
are not met, the SHSR is set to its minimum value of 35 F.
The Staged Heat Submaster Reference (SHSR) is calculated
as follows:
SHSR = Heating PID function on (error) where
error = (OHSP + STO) - Space Temperature

Dehumidification – The PremierLink controller will provide
occupied and unoccupied dehumidification control when
AUXOUT = 5 in the CONFIG table and is installed on HVAC
units that are equipped with additional controls and accessories
to accomplish this function. This function also requires a space
relative humidity sensor be installed on the OAQ/IRH input.
When in the occupied mode and the indoor relative humidity is greater then the Occupied High Humidity set point, then
the H3_EX_RV output point will be energized. When in the
unoccupied mode and indoor relative humidity is greater then
the Unoccupied High Humidity set point, then the H3_EX_RV
output point and supply fan output will be energized. There is a
fixed 5% hysteresis that the indoor relative humidity must drop
below the active set point to end the dehumidification mode
and deenergize the H3_EX_RV output. If the Premierlink controller is in the unoccupied mode, then the fan relay will deenergize if there is no other mode requiring to the fan to be on.
This function will not energize mechanical cooling as a result
of the indoor relative humidity exceeding either set point.
A high humidity alarm will be generated if the indoor relative humidity exceeds the high humidity set point by the
amount configured in the Control Humidity Hysteresis in the
ALARMS table for 20 minutes. The alarm will return to normal when the indoor relative humidity drops 3% below the active humidity set point.
Economizer — The economizer dampers are used to provide
free cooling and indoor air quality if optional CO2 sensor is installed and when the outside conditions are suitable. Temperature control is accomplished by controlling the SAT to a certain
level determined by the Economizer PID Loop by calculating a
submaster reference (ECONSR) value. This algorithm will calculate the submaster reference temperature (ECONSR) based
on OAT and enthalpy conditions and cooling requirements.
The ECONSR value is then passed to the Economizer Submaster Loop, which will modulate dampers to maintain SAT at
ECONSR level.
The following conditions are required to determine if economizer cooling is possible:
• Indoor fan has been on for at least 30 seconds
• Enthalpy is low
• SAT reading is available
• OAT reading is available
• SPT reading is available
• OAT ≤ SPT
• OAT < OATMAX (OATMAX default is 75 F)
• Economizer position is NOT forced
If any of the above conditions are not met, the ECONSR
will be set to its MAX limit of 120 F and the damper will go to
its configured minimum position. The minimum damper position can be overridden by the IAQ routine described later in
this section.
The calculation for ECONSR is as follows:
ECONSR = PID function on (set point – SPT), where:
set point = ((OCSP+STO) + (OHSP+STO))/2 when NTLO
(Unoccupied Free Cool OAT Lockout) < OAT < 68 F
setpoint = (OCSP+STO) – 1 when OAT ≤ NTLO
setpoint = (OHSP+STO) + 1 when OAT ≥ 68 F
The actual damper position (ECONPOS) is the result of the
following calculation. Values represented in the right side of
the equation can be found in the SERVICE configuration table
descriptions in this manual. Note that that the OAT is taken into
The Maximum SHSR is determined by the SATHI configuration. If the supply-air temperature exceeds the SATHI configuration value, then the heat stages will turn off. Heat staging
28
calculated IAQ minimum position is greater than the IAQ maximum damper position (IAQMAXP) decision in the SERVICE
configuration table, then it will be clamped to IAQMAXP
value.
If IAQ is configured for low priority, the positioning of the
economizer damper can be overridden by comfort requirements. If the SPT > OCSP + 2.5 or the SPT < OHSP – 2.5 then
IAQ minimum position becomes 0 and the IQMP = MDP. The
IAQ mode will resume when the SPT ≤ OCSP + 1.0 and SPT
≥ OHSP – 1.0.
If IAQ is configured for high priority and the OAT < 55 F
and the SAT < (SPT – 10° F), the algorithm will enable the heat
stages to maintain the SAT between the SPT and the SPT +
10° F.
IAQ Pre-Occupancy Purge — This function is designed to
purge the space of airborne contaminants that may have accumulated 2 hours prior to the beginning of the next occupied period. The maximum damper position that will be used is temperature compensated for cold whether conditions and can be
pre-empted by Temperature Compensated Start function. For
pre-occupancy to occur, the following conditions must be met:
• IAQ Pre-Occupancy Purge option is enabled in the CONFIG configuration table
• Unit is in the unoccupied state
• Current Time is valid
• Next Occupied Time is valid
• Time is within 2 hours of next Occupied period
• Time is within Purge Duration (user-defined 5 to 60 minutes
in the CONFIG configuration table)
• OAT Reading is available
If all of the above conditions are met, the economizer damper IQMP is temporarily overridden by the pre-occupancy
damper position (PURGEMP). The PURGEMP will be set to
one of the following conditions based on atmospheric conditions and the space temperature:
• If the OAT ≥ NTLO (Unoccupied OAT Lockout Temperature) and OAT < 65 F and OAT is less than or equal to
OCSP and Enthalpy = Low then PURGEMP = 100%.
• If the OAT < NTLO then PURGEMP = LTMP (Low Temperature Minimum Position – defaults to 10%)
• If the OAT > 65 F or (OAT ≥ NTLO and OAT > OCSP) or
Enthalpy = High then PURGEMP = HTMP (High Temperature Minimum Position defaults to 35%).
The LTMP and HTMP are user adjustable values from 0 to
100% in the SETPOINT table. Whenever PURGEMP results
in a number greater than 0%, the IAQ pre-occupancy purge
mode will be enabled turning on the Indoor Fan Relay and setting the economizer IQMP to the PURGEMP value. When
IAQ pre-occupancy mode is not active PURGEMP = 0%.
Unoccupied Free Cooling — Unoccupied free cool function
will start the indoor fan during unoccupied times in order to
cool the space with outside air. This function is performed to
delay the need for mechanical cooling when the system enters
the occupied period. Depending on how Unoccupied Free
Cooling is configured, unoccupied mode can occur at any time
in the unoccupied time period or 2 to 6 hours prior to the next
occupied time. Once the space has been sufficiently cooled
during this cycle, the fan will be stopped. In order to perform
unoccupied free cooling all of the following conditions must be
met:
• NTEN option is enabled in the CONFIG configuration table
• Unit is in unoccupied state
• Current time of day is valid
• Temperature Compensated Start mode is not active
• COOL mode is not active
• HEAT mode is not active
• SPT reading is available
• OAT reading is available
• Enthalpy is low
will resume after a delay to allow the supply-air temperature to
drop below the SATHI value.
The maximum number of stages available is dependent on
the type of heat and the number of stages programmed in the
CONFIG and SERVICE configuration tables. Staging will
occur as follows for gas electric units, Carrier heat pumps with
a defrost board, or cooling units with electric heat:
For Heating PID STAGES = 2
HEAT STAGES = 1 (50% capacity) - energize HS1.
HEAT STAGES = 2 (100% capacity) - energize HS2.
For Heating PID STAGES = 3 and AUXOUT = HS3
HEAT STAGES = 1 (33% capacity if) - energize HS1
HEAT STAGES = 2 (66% capacity) - energize HS2
HEAT STAGES = 3 (100% capacity) - energize HS3
Staging will occur as follows For heat pump units with
AUXOUT configured as reversing valve:
For Heating PID STAGES = 2 and AUXOUT = Reversing
Valve Heat (the H3_EX_RV output will stay energized until
there is a cool demand)
HEAT STAGES = 1 (50% capacity) shall energize CMP1,
CMP2, RVS.
HEAT STAGES = 2 (100% capacity) shall energize HS1
and HS2.
Heating PID STAGES = 3 and AUXOUT = Reversing Valve
Heat (the H3_EX_RV output will stay energized until there is a
cool demand)
HEAT STAGES = 1 (33% capacity if) shall energize
CMP1, CMP2, RVS
HEAT STAGES = 2 (66% capacity) shall energize HS1
HEAT STAGES = 3 (100% capacity) shall energize HS2
If AUXOUT is configured for Reversing Valve Cool, then
the H3_EX_RV contact will be deenergized when there is a demand for heating. The heat stages will be cycled to temper the
SAT so that it will be between the SPT and the SPT + 10° F
(SPT < SAT < (SPT + 10° F)) if:
• the number of heat stages calculated is zero
• the OAT < 55 F
• an IAQ sensor is installed
• the IAQ Minimum Damper Position > minimum damper
position
• and the SAT < SPT –10° F.
There is also a SAT tempering routine that will act as SAT
low limit safety to prevent the SAT from becoming too cold
should the economizer fail to close. One stage of heating will
be energized if it is not in the Cooling or Free Cooling mode
and the OAT is below 55 F and the SAT is below 40 F. It will
deenergize when the SAT > (SPT + 10° F).
Indoor Air Quality — If the optional indoor air quality (IAQI)
sensor is installed, the PremierLink™ controller will maintain
indoor air quality within the space at the user configured differential set point (IAQD) in the CONFIG configuration table.
The set point is the difference between the IAQI and an optional outdoor air quality sensor (OAQ). If the OAQ is not present
then a fixed value of 400 ppm is used. The actual space IAQ
setpoint (IAQS) is calculated as follows:
IAQS = IAQD + OAQ (OAQ = 400 ppm if not present)
As air quality within the space changes, the minimum position of the economizer damper will be changed also thus allowing more or less outdoor air into the space depending on the relationship of the IAQI to the IAQS. The IAQ algorithm runs
every 30 seconds and calculates IAQ minimum position value
using a PID loop on the IAQI deviation from the IAQS. The
IAQ minimum position is then compared against the user configured minimum position (MDP) and the greatest value becomes the final minimum damper position (IQMP). If the
29
Once Linkage is active, the PremierLink controller’s own
SPT, temperature set points, and occupancy are ignored and the
controller will use the information provided by the remote linkage device. The following information will be received from
the remote linked device and can be viewed in the maintenance
display table:
• Supervisory Element
• Supervisory Bus
• Supervisory Block
• Average Occupied Heat Setpoint
• Average Occupied Cool Setpoint
• Average Unoccupied Heat Setpoint
• Average Unoccupied Cool Setpoint
• Average Zone Temp
• Average Occupied Zone Temp
• Occupancy Status
In return, the PremierLink controller will provide its SAT
and operating mode to the linked device.
It will convert its operating modes to Linkage modes. See
Table 8.
• OAT > NTLO (with 1 degree F hysteresis) and < Max Free
Cool set point
If any of the above conditions are not met, Unoccupied Free
Cool mode will be stopped, otherwise, the mode will be controlled as follows:
The NTFC set point (NTSP) is determined as NTSP =
(OCSP + OHSP) / 2
The Unoccupied Free Cool mode will be started when:
SPT > (NTSP + 2° F) and SPT > (OAT + 8° F)
The Unoccupied Free Cool mode will be stopped when:
SPT < NTSP or SPT < (OAT + 3° F)
Temperature Compensated Start — This function will run
when the controller is in unoccupied state and will calculate
early start bias time (SBT) based on space temperature deviation from occupied set points in minutes per degree. The following conditions will be met for the function to run:
• Unit is in unoccupied state
• Next occupied time is valid
• Current time of day is valid
• Valid space temperature reading is available (from sensor or
linkage thermostat)
• Cool Start Bias (KCOOL) and Heat Bias Start (KHEAT) >
0 in the CONFIG configuration table
The SBT is calculated by one of the following formulas depending on temperature demand:
If SPT > OCSP then SBT = (SPT – OCSP) * KCOOL
If SPT < OHSP then SPT = (OHSP – SPT) * KHEAT.
The calculated start bias time can range from 0 to 255 minutes. When SBT is greater than 0 the function will subtract the
SBT from the next occupied time to calculate a new start time.
When a new start time is reached, the Temperature Compensated Start mode is started. This mode energizes the fan and the
unit will operate as though it is in occupied state. Once set,
Temperature Compensated Start mode will stay on until the
unit returns to occupied state. If either Unoccupied Free Cool
or IAQ Pre-Occupancy mode is active when Temperature
Compensated Start begins, their mode will end.
Door Switch – The Door Switch function is designed to disable mechanical heating and cooling outputs when the
REMOCC contact input is closed (in the ON state) after a programmed time delay. The fan will continue to operate based on
the current mode and the ASHRAE 90.1 Supply Fan setting.
The delay is programmable from 2 to 20 minutes by setting the
Remote Cont/Door Switch decision in the SERVICE table to a
value equal to the number of minutes desired. When the contact is open (in the OFF state), the PremierLink controller will
resume normal temperature control.
This application is designed for use in schools or other public places where a door switch can be installed to monitor the
opening of a door for an extended period of time. The controller will disable mechanical cooling and heating when the door
is open for a programmed amount of time.
This function can also be used to monitor a high condensate
level switch when installed on a water source heat pump to disable mechanic cooling in case of a plugged evaporator condensate pan drain.
Linkage — The Linkage function in the PremierLink™ controller is available for applications using a Linkage thermostat
or the 3V™ control system. If using the Linkage thermostat,
both the PremierLink controller and the stat must be on the
same CCN bus. When used as the air source for a 3V control
system, the PremierLink controller is not required to be on the
same CCN bus but it is recommended. Linkage will be active
when it is initiated from the Linkage thermostat or the 3V
Linkage Coordinator through CCN communications and requires no configuration. Only one device can be linked to the
PremierLink controller.

The PremierLink controller will generate a Linkage Communication Failure alarm if a failure occurs for 5 consecutive
minutes once a Linkage has previously been established. It will
then revert back to its own SPT, set points and occupancy
schedule for control. For this reason, Carrier strongly recommends that an SPT be installed in the space on open plenum
systems or in the return air duct of ducted return air systems to
provide continued backup operation. When Linkage communication is restored, the controller will generate a return to
normal.
For more information on how the PremierLink controller is
used in conjunction with the Carrier 3V control system, contact
your CCN controls representative.
IMPORTANT: The PremierLink controller should not be
used as a linked air source in a ComfortID™ VAV system.
The ComfortID VAV system will NOT function correctly
when applied with a PremierLink controller as the air
source, resulting in poor comfort control and possible
equipment malfunction.
NOTE: The PremierLink controller can be used as an air
source in a 3V Pressure Independent (PI) System (a 3V Linkage Coordinator with ComfortID PI Zone Controllers), but it
should not be used as an air source with ComfortID controllers
unless a 3V zone controller is used as the Linkage Coordinator.
Contact your Carrier CCN controls representative for assistance.
Demand Limit — If the demand limit option is enabled, the
control will receive and accept Redline Alert and Loadshed
commands from the CCN load shed controller. When a redline
alert is received, the control will set the maximum stage of
30
capacity equal to the stage of capacity that the unit is operating
at when the redline alert was initiated.
When load shed command is received the control will reduce capacity as shown in Tables 9 and 10.

MANUAL OVERRIDE HOURS — The Manual Override
Hours point is used to command a timed override by entering
the number of hours the override will be in effect. If the occupancy schedule is occupied when this number is downloaded,
the current occupancy period will be extended by the number
of hours downloaded.
If the current occupancy period is unoccupied when the
occupancy override is initiated, the mode will change to occupied for the duration of the number of hours downloaded. If the
occupancy override is due to end after the start of the next
occupancy period, the mode will transition from occupancy
override to occupied without becoming unoccupied and the
occupancy override timer will be reset.
An active occupancy override or a pending occupancy
override may be canceled by downloading a zero to this
configuration. Once a number other than zero has been downloaded to this configuration, any subsequent downloads of any
value other than zero will be ignored by the controller.

SAT CMP1 LOCKOUT TEMP — The SAT CMP1 Lockout
Temperature displays the low supply temperature set point for
compressor no. 1 supply air during cooling. If compressor no. 1
is on during Cooling mode, the economizer will assist the cooling and work to maintain a discharge air temperature slightly
above lockout temperature set point. If the economizer is at
minimum and the supply-air temperature goes below Lockout
Temperature set point, the compressor will cycle to maintain
the supply air set point. The minimum on and off times will
still be in effect.

STAGED COOLING — The staging function is used for DX
cooling (1 or 2 stages). The staging function uses the cooling
submaster reference from the PID and compares the value to
the supply-air temperature to calculate the required number of
output stages to energize.
Time Guard delays are provided to allow for up to 2 stages
of compression. Also, a DX Lockout will prevent operation
of the DX cooling if the outdoor air temperature is below this
value.
The cooling algorithm controls the valve or stages of DX
cooling to prevent the space temperature from exceeding the
current cooling set point (which includes any calculated offset
value from a T56 sensor slide bar or T59 sensor during occupied periods). Also, the cooling is controlled so that the supply
air temperature does not fall below 50 F when cooling is active.
Number of Stages: Range
1 to 3
Default Value
2
The Time Guards must be set to Enable for output to a
compressor, and set to Disable for output to a valve or
compressor unloader.
When enabled, the staging PID loop will have a minimum
delay of 3 minutes before adding the stage and dropping the
stage after it is started. This delay will run concurrently with
the Compressor Minimum On (C_MIN_ON) and Off
(C_MIN_OF) delays found in this table. The actual compressor on/off delays will be the greater of the two functions.
When disabled, there will be no delay in adding or droping the
stage other then the Compressor Minimum On and Off Delays.
NOTE: Stage 1 Time Guard cannot be disabled.

HEATING PID — The PremierLink™ controller determines
if a heating demand exists in the space. The controller reads the
space temperature sensor and compares the temperature to the
current low set point (including any calculated offset value
from a T56 or T59 sensor) during occupied periods. If it is
below the set point, and heating is configured and available, it
then calculates the required supply-air temperature to satisfy
the given conditions. The calculated value (heating submaster
reference) is compared to the actual supply-air temperature and
STAGED HEATING — The Staged Heating function is used
for two-position valves or for electric heat (1 or 2 stages). The
staging function uses the heating submaster reference value
from the PID and compares it to the supply-air temperature to
calculate the required number of output stages to energize. The
time guard, when enabled, will increase the heat output minimum off time from 3 minutes to 5 minutes.

IAQ PID — The proportional gain affects the response of PID
calculations for staged control. The gain is also used for two
position control to establish the hysteresis between on and off.
A larger gain speeds response time or reduces the hysteresis,
while a smaller gain requires a larger error to generate the same
response to changes in Indoor Air Quality. Enter the desired
proportional gain for the Indoor Air Quality control algorithm.
The integral gain affects the PID calculation; an increase
will make the IAQ submaster reference change greater as the
error in indoor air quality increases. The integral gain should be
selected to eliminate proportional droop without overshoot.
Enter the desired integral gain for the Indoor Air Quality control algorithm.
The Derivative Gain is typically not required for Indoor Air
Quality operation and should be left at the default value.
The Starting Value is used to establish the starting value for
the IAQ PID calculation.

ECONOMIZER PID — The proportional gain determines the
response of the PID temperature control loop; a larger gain
increases the amount of damper movement while a smaller
gain requires a larger error to achieve the same results.
The integral gain affects the response of a PID calculation;
an increase in gain will compensate more quickly for proportional control droop. Too large of an integral gain will cause
excessive damper positioning and instability. Enter the desired
integral gain for the damper control algorithm.
The economizer derivative gain has been tested for ideal
operation in sensor mode and should be left at the default value.
NOTE: In thermostat mode, the modulation may appear to
regularly change. However, it will precisely control leaving-air
temperature.
The economizer Starting Value is used to establish the starting value for the damper PID calculation. The Economizer PID

Features/Benefits
Available for wide range of
rooftop applications
The PremierLink™ controller is available as a field retrofit application and
can control one or several rooftop units
with (multiple controllers) from 3 to
25 tons. In addition, it has an integrated
economizer controller that eliminates
the need for a separate circuit board.
The PremierLink controller can be
installed on the following Carrier rooftop units: 48/50HJ (3 to 121/2 tons),
48TF/50TFF (3 to 121/2 tons), and
48/50TJ (121/2 to 25 tons). Other

When connected to a Carrier Linkage
Thermostat, the PremierLink controller
can use occupancy schedules, zone temperature, and set points from the thermostat. The PremierLink controller
provides the thermostat with the unit’s
operating mode and supply air temperature for local display at the thermostat.
When used with the Linkage Thermostat, the PremierLink controller provides local space temperature sensing,
(remote space temperature sensing and
averaging with up to 3 optional remote
room sensors), occupied and unoccupied heat and cool set points, occupancy scheduling with up to 8 time
periods, 12 holiday periods, network
time broadcast, occupied set point
range limiting, temperature compensated start, and global occupancy. A single Linkage Thermostat will have the
ability to interface with up to 8 rooftop
controls serving a single zone with the
ability to unlink if communications to
the linkage thermostat are lost.
initialized via the network. The PremierLink controller offers override invoked
from a wall sensor during unoccupied
hours from 1 to 4 hours in 1-hour
increments.
The PremierLink controller offers
ventilation monitoring with an optional
CO2 ventilation sensor. The CO2 ventilation sensor measures the amount of
ventilation needed by the space and a
proportional integral derivative loop
(PID) calculation makes adjustments to
the economizer minimum position during occupied operation. The indoor
CO2 will be compared to an outdoor
CO2 reference before making adjustments to the economizer minimum
position.
Using a space sensor with set point
adjustment, timed override and service
port jack, the PremierLink controller
will provide intelligent compressor staging and economizer operation.
Modulating control of the economizer
will assist mechanical cooling without
adversely affecting compressor performance. Economizer assisted cooling is
determined from a comparison of space
temperature, outside air temperature
and an enthalpy switch input. The
switch input can also be used for differential enthalpy input, meeting ASHRAE
Standard 90.1.
The T58 Communicating Space temperature sensor with service port jack
provides set point adjustment, timed
override, force fan and read equipment
mode and measures and maintains
room temperature by communicating
with the PremierLink controller.

Simple mounting and ease of
installation
Carrier’s unique, hand-held diagnostic
tool, Navigator, can be used with the
PremierLink controller. Instant access to
detailed information is provided to technicians. Access is available via an RJ-11
connection or a 3-wire connection to
the communication bus.
Navigator offers flexibility for fast
service. Technicians can monitor rooftop operation from the rooftop’s main
control panel. Additional hardware or
controller configuration is required for
Navigator applications.
The PremierLink controller has an integrated plastic cover with secured with
two plastic tabs that can be removed for
ease of installation.
For ease of installation, PremierLink
controller is provided with removable
Molex connectors which include pigtails
for easy installation to unit or sensors

System Pilot
Installation
The System Pilot is a wall mounted device. Refer to the System Pilot
Installation and Operation Instructions (Catalog # 533-30013) for
instructions on mounting the System Pilot on the wall.
Power Supply
Installation
The Universal Controller uses any standard, Class II, SELVcompatible, field-supplied 24 Vac power source. The power requirement is as follows:
60 VA @ 24 Vac + 15%
All installation wiring must conform to the following requirements:
•
All applicable local codes, ordinances, and regulations must be
observed.
•
All module power wiring must be as short as possible.
•
Primary power wiring must be run in separate conduit or Electrical
Metallic Tubing (EMT) from the CCN Communication Bus, sensor
field wiring, and device field wiring.
The power supply must be minimum 60VA, Class II rated, with a fused
secondary. A 3.3A slow blow fuse is recommended. Install it according
to the manufacturer’s installation instructions.
Warning:
Power Wiring
Do not plug in or turn on the power supply at this time.
Module power wiring can be completed only after the module is installed
in the enclosure. This section describes how to wire power connections
to the Universal Controller.
The CCN Installation and Start-up Manual (808-211) provides U.S.
and international wire specifications for various applications and lists
recommended wire vendors.
Warning:
When using a 24 Vac power supply to power the Universal
Controller, do not use it to also power non-controller type
devices such as sensors and actuators. If sharing power
between other CCN controllers, you must maintain phasing
between devices (see Power Requirements in Appendix
C).

Communication
Wiring
CCN communication wiring can be completed only after all Universal
Controllers are installed in their enclosures. This section describes how
to wire CCN communication to the Universal Controller and
ComfortVIEW.
The CCN Installation and Start-up Manual (808-211) provides U.S.
and international wire specifications for various applications and lists
recommended wire vendors.
The CCN Communication Bus conveys commands and data between the
Universal Controller and any other element on the CCN. Physically, the
CCN Communication Bus consists of three-conductor, shielded cable.
System elements must be connected directly to the bus in a daisy chain
fashion without the use of T-taps or spurs.
13
When connecting the CCN Communication Bus to a system element,
each of the three conductors must be used for the same signal type
throughout the entire CCN. That is:
•
•
•
signal (+) terminals must always be wired to signal (+)
signal ground terminals must always be wired to signal ground
signal (-) terminals must always be wired to signal (-)
To achieve this consistancy, the following “color code” system is recommended:
Signal Type
Conductor Insulation Color/Pin #
+
Ground
-
Red
White
Black
(1)
(2)
(3)
If a cable with a different color scheme is selected for the CCN Communication Bus, a similar color code system should be adopted to simplify
installation and checkout.
Grounding of Bus
Shields
At each system element, the shields of its communication bus cables must
be tied together. If the CCN Communication Bus is entirely within one
building, the resulting continuous shield must be connected to ground at
only one single point (refer to Figure 7). If the CCN Communication Bus
exits from one building and enters another, its shields must also be
connected to ground at a lightning suppressor in each building.
The specific shield connections are illustrated on the following pages in
the wiring description for each system element type.
14
Figure 7
CCN Communication Wiring
All buses, both primary and secondary, are composed of bus segments.
A bus segment may be up to 1000 feet in length. A Repeater functions
to join two bus segments. Up to three Repeaters can be used to form a
bus, consisting of four 1000-foot segments.

Sensor and Device
Wiring
The following section lists general procedures and guidelines for wiring
sensors and output devices. The CCN Installation and Start-up
Manual (808-211) provides U.S. and international wire specifications
for various applications and lists recommended wire vendors.
Appendix B of the Universal Controller Overview and Configuration
Manual (808-346) lists the engineering units, ranges, resolutions, and
accuracy for the standard input and output devices that the Universal
Controller supports.
Wiring Guidelines
Sensor and output device wiring is usually done in two stages. First,
bring the wiring to the enclosure. Then terminate the wire to the module
connectors.
1.
Mark each wire with the cable number specified on the module
wire list. Refer to Appendix A for a sample wire list.
2.
Pull the sensor and device wiring into the enclosure. Route all
sensor and device wiring through either the top or bottom of the
enclosure.
17
Note:
Pulsed-type discrete input sensors require twisted
shielded pair (tsp) wiring. Terminate the shield from the
sensor to a forked type crimp connector, allowing
enough wire so that this shield can be fastened under the
module mounting screw.
If the Universal Controller is not already installed, leave about 2
feet of wire in the enclosure before terminating the wire to the
module connectors.
3.
Refer to Field Wiring in the Checkout section prior to terminating
the wires.
4.
Terminate the wires to the module I/O connectors, as shown in
Figures 10 through 13 on the following pages.
Wire to the terminals designated on the wire list. Make final
termination by stripping the end of each wire, inserting it into the
connector, and tightening the adjacent screw. Refer to Figures 10
through 13 for more detailed information.
Note:
5.
Bundle and dress all cables according to module and connector.
Refer to Figure 14.

You should configure channel B as a setpoint offset hardware
input type point.
When wiring the Automation Components Inc. 10K-CP (Carrier part
number 33ZCT56SPT) sensor with slidebar, follow the guidelines below:
•
The sensor requires one temperature input hardware point and one
setpoint offset point on the Universal Controller, one for the thermistor and one for the slidebar.
•
Wire both inputs to the same controller, and run a 3-wire cable to the
sensor.
•
The ACI sensor has four terminals. The second SEN terminal (on
left), and the first (SET) terminal (on right) should be jumpered
(common wire).
•
Since there is a common for both signals and both inputs wired to the
same module, do not jumper the signal commons on the controller
(pin 2 of both channels).
Configuration
Guidelines
The temperature input for an ACI/10K-CP must be configured as a type
3 (10K Type II (CP/MCI)) temperature sensor. The slidebar input must
always be configured as a setpoint offset type analog input.
When using this sensor, you must configure the setpoint reference (Offset
Low Value/Offset High Value) decisions in the setpoint offset configuration table.
The actual biased setpoints are visible in the setpoint offset maintenance
table, based on the current slidebar position. The slidebar units are
displayed as 0 to 100%, where 50% is the center position (no setpoint
bias), 0% is the full low (minus), and 100% is the full high (plus) setpoint
bias position.

Checkout
Introduction
Checkout
This section describes basic checkout procedures that you should follow
before and after you complete the installation.
Note:
Field Wiring
Because these procedures are interdependent, you should
perform them in the order in which they are presented.
The first step in checking out an installation is to verify the field wiring by
checking for stray voltage, shorts and grounds, or resistance.
1.
Turn module power off.
2.
Verify that I/O connectors are removed from the module.
3.
Using the wire list as a guide, locate the wiring pair associated
with the point to be verified.
4.
For the same point, go to the sensor or controlling relay and
remove the wiring pair from the device terminals. Short the
two wires together.
5.
Return to the module and use a VOM to measure the resistance
across the wiring pair described in Step 3 above. The reading
should be less than 5 ohms.
6.
Go to the sensor or controlling relay and remove the short
described in Step 4 above. Do not re-connect the wires to the
sensor at this time.
7.
Return to the module and again use a VOM to measure the
resistance across the wiring pair. The reading should measure
an open, or infinite ohms.
8.
If either of the resistances measured in Steps 5 and 7 above
was incorrect, a problem exists in the wiring. Replace the
wiring pair, or repair wiring if practical.
9.
If both measurements were correct, continue with the next
procedure.
10.
Check between each wire and ground for AC voltage, DC
voltage and continuity. Correct as needed.
23
Power Supply
Diagnostic LEDs
The next step in checking out an installation is to verify that the power
supply is operating.
1.
Apply 120 Vac or other line voltage to the primary side of the
power supply.
2.
Ensure that 24 Vac + 15% is present on the power connector
before you plug it into the module.
The Universal Controller features the diagnostic LEDs shown in the figure
below.

The following table shows the status of the Universal Controller as
indicated by the blink rate of the red LED.

Follow the steps below to verify module operation.
1.
Before applying power to the module, be sure that the I/O
connectors are disconnected from the module.
2.
Power the module. The red LED should flash at the "Start-up
Mode" 1.0 Hz rate (On for 4/5 second, Off for 1/5 second),
for 3 seconds. Then the red LED will stay On (not blinking)
for less then 30 seconds. Finally, the red LED will flash at
the “Normal” 0.5 Hz rate. (On for 1 second, Off for 1 second).
3.
Using the Address Change Utility or System Pilot, verify that the
CCN address setting is correct.
1.
After you have determined that the wiring between the module and the sensor or controlling relay is correct, you should
then determine if the device itself is functional.
2.
If the device is a temperature sensor, verify that it is properly
mounted at the correct location as shown in the installation
drawings. Be sure that space sensors are not located near
coffee pots, copying machines, or other sources of heat or
cold.
3.
If the device is a thermistor, or a DO relay coil, use a VOM to
measure resistance across the device terminals. Compare this
measurement to Table 3. If the measurement is correct, reconnect all wiring between the device and the module. If the
measurement is incorrect, replace the failed device and reconnect all wiring between it and the module.
4.
If the device is a 2-wire, 4-20 mA type, there is no simple
verification procedure. In this case, assume that it is functional until all device and module wiring, configuration
decisions, and setpoint schedules are verified as correct. The
4-20 mA device should be replaced only after all other parameters have been checked thoroughly.
25
5.
If the device is a motor current transducer CT-1, the verification
procedure is as follows:
Warning:
a.
Before servicing this device or any device inside
a motor control panel, be sure to disconnect the
high voltage supply.
Verify motor current transducer CT-1 is installed and
properly wired in the correct part of the starter circuit as
shown in the installation drawings.
b. Verify wiring from the module to CT-1 by following the
External Devices procedure above, then re-connect the
wiring pair at the device terminals.
c.
Re-connect the high voltage supply to the motor control
panel.
d. Return to the module. Do not connect the field wiring
connector to the module.
e.
6.
Table 3
Temperature to Resistance
Conversion
Manually run the machine up to full load. Use a VOM to
measure the voltage across the device wiring pair. The
reading should be 1 to 5 Vdc. If the voltage is incorrect,
replace motor current transducer CT-1.
After external wiring and devices have been determined to be
functional, re-connect the field wiring connector to the module.

At this point, you should refer to the Universal Controller Overview
and Configuration Manual (808-346) for instructions on how to
configure the newly installed Universal Controller.
After the Universal Controller is configured, use the System Pilot or
ComfortVIEW to verify that each sensor or transducer works correctly.
Input and Output
Device
Connection
Input Devices
The final step in the Universal Controller checkout is to connect the
field devices to the module and check their operation. This requires
physical inspection of the devices.
1.
Plug the field wiring connector into the module.
2.
Display each input channel.
3.
Check each input’s accuracy by comparing the data displayed
on the System Pilot with the actual temperature, status, pressure,
etc., at the input device.
Note:
4.
30
For AI points, verify the physical location of the
sensor. For example, is the discharge sensor downstream from the coil? Is the space sensor in the
correct space? Is the pressure sensor in a nonturbulent area?
If any input does not checkout properly, verify its hardware
and software configuration. Inputs that have slightly inaccurate readings can be trimmed.
Output Devices
Caution:
1.
Force each output to a safe position.
Caution:
Discrete Outputs
Tuning Control
Loops
You must correct inaccurate inputs before connecting
output devices.
This is very important because the module will take control
of the output devices as soon as you plug the field connectors into the module. The safe position ensures an orderly
checkout procedure without disrupting normal building
operation.
2.
Plug the field connectors into the module.
1.
Display each discrete output.
2.
Force the device on (or off) and verify its operation.
3.
Force the device off (or on) and verify its operation.
4.
Remove the force as each discrete output passes checkout.
Observe proper algorithm control of each point before proceeding.
The following section offers a suggested procedure for control loop
tuning if an application consists of a heating, cooling, or other
device controlled by an analog, 4-20 mA actuator. While necessarily generic in nature, these steps can be used by any Carrier controller containing PID based analog output control loops.
The sensitivity of most HVAC processes varies with changes in air
temperature, water temperature, air volume, and other environmental conditions. Therefore, HVAC control loops periodically need recalibration or tuning to maintain a steady, stable response through
seasonal changes.
The most common indications that a loop requires tuning are:
•
The output oscillates, in some cases from the maximum to the
minimum output value, and the loop is unable to maintain
setpoint.
31
•
The controlling sensor is away from the setpoint by more than an
acceptable amount, but the output to the controlling device
(valve, damper, etc.) does not respond over a reasonable time
period.
In some cases, the control loop tuning precision that can be attained
depends on the application. For example, when controlling a mixed
air damper, the proportion of outside to return air for a given commanded position varies because of mechanical looseness in the
damper/actuator assembly. A mixed air damper control algorithm is
considered to be well tuned if the mixed air temperature is maintained within one degree F of setpoint. Dual loop algorithms controlling space conditions can be adjusted such that the setpoint can
be maintained within several tenths of a degree F.
For most HVAC situations, a somewhat sluggish response to
changes in setpoint or in the value of the controlling sensor is
desired. Tuning to provide rapid, knee-jerk response, while desirable in some situations, will invariably lead to tuning problems
when environmental conditions change. The need for re-tuning the
loop will be minimized with a slow but steady system response.
You will tune a control loop using the PID Master Loop and
Submaster Loop configuration decisions. Refer to the Universal
Controller Overview and Configuration Manual (808-346) for
information on the software aspects of control loop tuning.
Definition of Terms
Error
The difference between the reference (Master or Submaster, ie., the
setpoint) and the controlling sensor. (See the Equations section that
follows.)
Master Proportional Equation
A component of the Master Proportional, Integral and Derivative
(PID) Equation (see Equations) which calculates the Submaster
Reference (SubRef). Varies the SubRef based on the magnitude of
the Error and the time away from setpoint.
Master Proportional Gain
Used to adjust sensitivity of the Master Proportional Equation.
32
Master Integral Equation
A component of the Master PID Equation which calculates the
Submaster Reference. Varies the SubRef based on the magnitude of
the error and the amount of time it has existed.
Master Integral Gain
Used to adjust sensitivity of the Master Integral Equation.
Master Derivative Equation
A component of the Master PID Equation which calculates the
Submaster Reference. Varies the SubRef based on the rate of
change of the Error in the Master PID Equation.
Master Derivative Gain
Used to adjust sensitivity of the Master Derivative Equation.
Submaster Equation
Calculates the loop output which is proportional to the magnitude of
the Error in the Submaster Equation (see Equations).
Submaster Proportional Gain
Used to adjust sensitivity of the Submaster Equation.
Note:
Equations
For all single loop equations, use the master definitions
above.
All Universal Controller analog algorithms are based on PID equations. In a dual loop algorithm, the master loop calculates the
submaster reference and the submaster loop calculates the output
signal. In a single loop algorithm, the output signal is calculated
directly by a PID equation similar to the master loop equation.
These calculations are run at intervals as defined in the respective
algorithm's Block Iteration Rate configuration decision. Refer to the
Universal Controller Overview and Configuration Manual (808346) for information on the algorithm's configuration decisions.
These are the error calculations for the equations that follow:
Error1 = Setpoint - Value of Controlling Sensor
Error2 = Submaster Reference - Value of Submaster Sensor
33
These are the proportional (P Term), integral (I Term) and derivative
(D Term) terms for the equations that follow:
P Term = (Error1 * Proportional Gain)
I Term = (Error1 * Integral Gain) + Previous I Term
D Term = (Current Error1 - Previous Error1) * Derivative Gain
All single loop algorithms use the following equation:
Output Signal = P Term + I Term + D Term + Starting Value
Note:
Output Signal will not exceed the minimum and maximum
output values configured for the algorithm.
All dual loop algorithms use the following master and submaster
equations.
Master PID Equation:
Submaster Reference = P Term + I Term + D Term + Starting Value
Note:
Submaster Reference will not exceed the minimum and
maximum SubRef values configured for the algorithm.
Submaster Equation:
Output Signal = (Error2 * Submaster Proportional Gain) + Center
Value
Note:
System Checkout
Before you begin tuning the loop, check out the system and verify
the following:
1.
34
Output Signal will not exceed the minimum and maximum
output values configured for the algorithm.
There are no mechanical or electrical problems with the
controls or the controlled equipment. Devices such as valves,
dampers, and sensors must be operating properly.
2.
Whether the valves and dampers are normally open or normally closed so that the correct display types and gains can be
selected. For normally closed devices, the actual control
signal (mA or Volts) would be scaled such that the low end (4
mA or 2 Vdc) will display 0%, while the high end (20 mA or
10 Vdc) will display 100%. A normally open device will
invert that relationship such that 0% would equate to 20 mA
or 10 Vdc while 100% would equate to 4 mA or 2 Vdc.
The polarity and value of the gain is important, because they
determine the direction and magnitude of the output for a given
amount of error. The master and submaster loops are mathematical formulas whose response is tailored via these gains.
If set up properly, any increase in the algorithm’s output from
0 to 100% will result in an increase in output from the controlled device. As long as the output channels are set up with
display types that match the controlled device, then the
following will be true:
•
For all dual loops, the master proportional, integral, and
derivative gain will always be positive.
•
Dual loop heating algorithms will use positive submaster
proportional gain.
•
Dual loop cooling algorithms will use negative submaster
proportional gain.
•
Single loop heating algorithms will use positive proportional, integral, and derivative gain.
•
Single loop cooling algorithms will use negative proportional, integral, and derivative gain.
Note:
3.
All derivative gains have a default value of zero.
The system must be operating under actual load conditions.
If conditions are atypical, any adjustments will be invalid
when normal operating conditions return.
35
Determination of
Throttling Range
Caution:
You must determine the throttling range of the controlled
device prior to attempting to tune the control loop.
The throttling range of a device can be defined as the range of
output over which the device produces a measurable effect. You
must differentiate between the throttling range and the mechanical
or electrical spring range since the range over which the device
(value, damper, etc.) produces a measurable effect (heat, cool,
pressure, etc.) is almost surely to be less than the full spring range.
Once the true throttling range is determined, the center value (for
dual loops) or starting value (for single loops) can be determined.
The Center Value (CV) or Starting Value (SV) can be defined as the
center of the throttling range. This may be the mathematical center
of the spring range or it may not. For systems which have a very
non-linear response, such as a steam valve which opens with a great
rush of heat, the CV or SV will be closer to the closed end of the
spring range rather than the middle.
To make this determination, the actuator should be stroked over its
entire range while monitoring the leaving conditions of the device.
This procedure provides the means of determining not only the
device's center, but also the point where it begins working, and
finally the point where it reaches its maximum capability. You
should plot the leaving conditions as a function of output, beginning
at a fully closed output and continuing until the leaving conditions
no longer change. To insure accuracy over a variety of conditions,
this should be done when load conditions are typical for the operation of this device.
If you are tuning a dual loop algorithm, enter the center value in the
Submaster Loop Center Value configuration decision. If you are
tuning a single loop algorithm, enter the starting value in the PID
Master Loop Starting Value configuration decision.
Dual Loop PID Tuning
36
All control loops in a Universal Controller allow user adjustment of
loop timing. The default for all dual loops is 120 seconds for the
master loop and 2 seconds for the submaster loop. It is suggested
that the defaults be maintained unless there is a compelling reason to
change them.
The following steps apply only to dual loop algorithms:
1.
Set the Center Value.
Verify the correct submaster center value as outlined in
Determination of Throttling Range.
2.
Tune the Submaster Loop.
Force the submaster reference to a value several degrees
above or below the current value of the submaster sensor.
This will cause the controlled device to operate in the middle
portion of its throttling range. Since the accuracy of the
center value has already been proven, any problems with the
submaster loop can normally be attributed to improper settings of the submaster gain. Observe the loop response and
determine if any of the following conditions are present:
•
Loop Oscillation.
An excessive amount of submaster gain is indicated if the
submaster sensor and output signal repeatedly oscillate
and do not stabilize. To correct for this condition, reduce
the submaster proportional gain in 50% increments until
the oscillation subsides, and then bring it back up by half
of the amount reduced, again verifying that the loop
remains free of oscillation. Should this increase return
the loop to oscillation, again reduce the gain by one half
of the increased amount. The intent is to produce a
steady output signal within +/- 5% of the target submaster
reference.
•
Droop
Droop is indicated if the output is stable (not oscillating)
but the submaster sensor is more than +/- 5% of reference
away from the target submaster reference. Assuming
proper adjustment of the submaster gain, this condition
normally indicates that the center value was incorrect.
Increase or decrease it until the submaster sensor is
within +/- 5% or the submaster reference. Again, the goal
is to produce a steady output signal within +/- 5% of the
target submaster reference.
37
•
3.
Set the Master Integral Gain to 0.
4.
Adjust the Master Proportional Gain.
At this point, the submaster loop is stable and its gain has
been adjusted for proper response. Adjust the setpoint to a
value +/- 5% away from current conditions at the controlling
sensor (normally the space sensor) and remove the submaster
force to allow the master loop to calculate a new submaster
reference (based on the amount of error between the master
sensor and the setpoint). This will allow the equipment to
operate with a legitimate load. Observe the loop response and
determine if the following condition is present:
•
5.
38
Inverse Loop Polarity
If the output responds in reverse of what is expected, reverse
the polarity of the submaster gain (+/-). An example of this
condition is when the reference requires heat, but the valve
goes closed or moves towards closed. After the required
corrections are made, re-evaluate for the other possible
conditions.
Loop Oscillation.
If the submaster reference swings wildly from its maximum to its minimum allowable value, the most likely
cause is an excessive amount of master proportional gain.
Reduce the master proportional gain in increments of
50% until stability results, then increase its value by half
of the reduced amount. Since the master loop in this
example runs every two minutes, you are advised to allow
a minimum of eight minutes (four loop iterations) between successive gain adjustments. The intent is to
produce a steady output signal without reaching the
minimum and maximum submaster values. At this point
the loop should stabilize at an output that will likely not
achieve setpoint. This is normal, and we will compensate
for this by adjustment of the integral gain.
Set the Integral Gain.
Once the proportional gain is established, input a value of
integral gain that is between 10% and 50% of the proportional
gain. This will cause the output to increase or decrease incrementally at each loop iteration until setpoint is achieved. If the output
causes a setpoint overshoot, reduce the integral gain by 50% of
the initial value and re-evaluate the loop’s response. The goal is
to cause the loop to gradually approach and achieve setpoint with
minimal overshoot. Since the master loop in this example runs
every two minutes, you are advised to allow a minimum of eight
minutes (four loop iterations) between successive gain adjustments.
After making any necessary adjustments to the master loop,
the output should be stable (not oscillating) and the controlling sensor should be at or approaching setpoint. A change in
setpoint or in the value of the controlling sensor should cause
the output to move steadily in the appropriate direction, and
allow the loop to reach setpoint in a reasonable period of
time.
6.
Adjust the Derivative Term.
Determine if the application requires a derivative term.
Normally, this would only be required when, after careful
adjustment of the submaster’s proportional gain and the
master’s proportional and integral gains, excessive overshoot/
undershoot is observed. The purpose of the derivative term is
to reduce or eliminate overshoot in systems which have a very
rapid rate of change at the controlling sensor. Most HVAC
applications that use a master/submaster approach do not
respond that quickly, therefore the derivative is normally not
necessary or used. As such, the default value for the derivative gain is zero. The actual mathematical function of the
derivative term is two-fold; it will subtract from the value of
the proportional and integral calculation (thus reducing
overall output) when the controlling sensor is approaching
setpoint, and conversely, it will add to the proportional and
integral calculation (thus increasing the overall output) in
cases where the controlling sensor is drifting away from
setpoint. In cases where there is no change in the value of the
controlling sensor, (that is to say the change in loop error is
zero), the derivative will have no effect (the calculated derivative term is zero).
39
If after careful adjustment of the proportional and integral gains,
your application does require a derivative term (indicated by
excessive overshoot), set it to a value approximately 25% of the
proportional gain, and re-test and re-adjust (by +/- 50% intervals)
until overshoot is reduced to a satisfactory level.
Single Loop PID Tuning
As was the case with dual loop tuning, the entire system (controls,
mechanical equipment, etc.) must be thoroughly evaluated before
proceeding. The throttling range must also be determined using the
procedure described in Determination of Throttling Range above.
When those steps are completed, the actual tuning procedure may
commence.
The AO—Adaptive Single Loop PID is the only single loop algorithm in the Universal Controller. The optimum loop timing (set via
the Block Iteration decision) will vary based on the nature of the
application. The default value of 10 seconds may not be appropriate
for all applications. The user is advised to adjust this value to reflect
the actual time constant of the controlled process (the time it takes to
stabilize after a step change of output to the controlled device).
The following steps apply to single loops only. During the following procedure, if the output responds in reverse of what is expected,
reverse the polarity of the proportional, integral, and derivative gains
(+/-). In all cases, the polarity of the proportional, integral, and
derivative gains must be the same. An example of the output responding in reverse of what is expected is when the reference
requires heat, but the valve goes closed or moves towards closed.
40
1.
Set the Starting Value.
Verify the correct starting value as outlined previously in the
Determination of Throttling Range section of this chapter.
2.
Force the Output.
Force the output to its minimum position.
3.
Set the Master Integral Gain to 0.
4.
Set the Proportional Gain.
Release the output force and adjust the setpoint to a value that
will cause the output to increase. This will cause the controlled device to begin operating under automatic control.
Since we have already proven the accuracy of the starting
value, any problems with the loop can be attributed to improper settings of gain. Observe the loop response over
several minutes time, and identify whether the following
conditions apply:
5.
•
Loop Oscillation.
An excessive amount of proportional gain is indicated
when the controlling sensor and output oscillate. To
correct for this condition, reduce the proportional gain in
50% increments until the oscillation subsides, and then
bring it back up by half of the amount reduced, again
verifying that the loop remains free of oscillation. Should
this increase return the loop to oscillation, reduce the gain
by one half of the increased amount. The intent is to
produce a steady output signal within +/- 5% of the target
setpoint.
•
Droop
Droop is indicated if the output is stable (not oscillating)
but the controlling sensor is more than +/- 5% of reference away from the target setpoint. Assuming proper
adjustment of the proportional gain, this condition normally indicates that the starting value was incorrect.
Increase or decrease it until the controlling sensor is
within +/- 5% of the setpoint. The goal is to produce a
steady output signal within +/- 5% of the target setpoint.
Set the Integral Gain.
Once the proportional gain is established, input a value of
integral gain that is between 10% and 50% of the proportional
gain. This will cause the output to increase or decrease
incrementally at each loop iteration until setpoint is achieved.
If the setpoint is exceeded indicating overshoot, reduce the
integral gain by 50% of the initial value and re-evaluate the
loop’s response. The goal is to cause the loop to gradually
approach and achieve setpoint with minimal overshoot.
41
After making these adjustments, the output should be stable (not
oscillating) and the controlling sensor should be at or approaching
setpoint.
6.
Adjust the Derivative Term.
Determine if the application requires a derivative term.
Normally, this would only be required when, after careful
adjustment of the submaster’s proportional gain and the
master’s proportional and integral gains, excessive overshoot/
undershoot is observed. The purpose of the derivative term is
to reduce or eliminate overshoot in systems which have a very
rapid rate of change at the controlling sensor. Most HVAC
applications that use a master/submaster approach do not
respond that quickly, therefore the derivative is normally not
necessary or used. As such, the default value for the derivative gain is zero. The actual mathematical function of the
derivative term is two-fold; it will subtract from the value of
the proportional and integral calculation (thus reducing
overall output) when the controlling sensor is approaching
setpoint, and conversely, it will add to the proportional and
integral calculation (thus increasing the overall output) in
cases where the controlling sensor is drifting away from
setpoint. In cases where there is no change in the value of the
controlling sensor, (that is to say the change in loop error is
zero), the derivative will have no effect (the calculated derivative term is zero).
If after careful adjustment of the proportional and integral
gains, your application does require a derivative term (indicated by excessive overshoot), set it to a value approximately
25% of the proportional gain, and re-test and re-adjust (by +/50% intervals) until overshoot is reduced to a satisfactory
level.

GENERAL
the SPT sensor. The Network Service Tool can be used to adjust set points, set operating parameters, and fully configure the
zone controller or any device on the system.
The zone controller is a single duct, fan powered, Variable
Air Volume (VAV) terminal control with a factory-integrated
controller and actuator. The zone controller maintains precise
temperature control in the space by operating the terminal fan
and regulating the flow of conditioned air into the space. Buildings with diverse loading conditions can be supported by controlling reheat or supplemental heat.
The VAV Fan Terminal Zone Controller (33ZCFANTRM)
provides dedicated control functions for series fan or parallel
fan powered terminals, single duct terminals with 3 stages of
heat, or as a primary controller for dual duct or zone pressure
control applications.
The Single Duct Air Terminal Zone Controller
(33ZCVAVTRM) provides dedicated control functions for single duct terminals with modulating heat or up to 2 stages of
heat.
When the VAV Fan Terminal Zone Controller is used in
conjunction with a secondary terminal and the 33ZCSECTRM
secondary terminal zone controller, either dual duct or zone
pressurization applications can be supported.
Carrier’s Linkage system is an integrated combination of
Carrier Comfort Network (CCN) controllers for use with Single Duct air terminals and VAV Fan Powered terminals. The
Single Duct air terminal and VAV Fan terminal zone controllers are part of the Carrier ComfortID system.
Devices manufactured by Carrier which have Product Integrated Controls on the same communication bus as the zone
controller, air handlers (such as the 39L,T), or large rooftop
units do not require an external controller to function as part of
a Carrier linkage system. These air handlers or large rooftop
units feature factory-installed Product Integrated Control (PIC)
controllers that are directly compatible with the system. Consult your local Carrier representative for the complete list of
compatible air handlers. The Comfort System AirManager
(CSAM) or the CC6400 supports linkage for non-Carrier devices or air handlers. Figure 1 shows an example of a Carrier
linkage system.
Zone Controller Hardware — The zone controller
consists of the following hardware:
• terminal control module
• torque-limiting damper actuator
• airflow transducer (velocity sensor)
• plastic enclosure
• one no. 8 x 1/2-in. sheet metal screw (to prevent zone
controller rotation)
NOTE: A filter is not provided for the airflow transducer.
For installations on systems with a high degree of impurities, an air filter can be purchased and installed on the transducer high pressure pickup.
Figure 2 shows the zone controller physical details.
Figures 3-5 show the 3 different types of zone controllers.
Field-Supplied Hardware — Each zone controller requires the following field-supplied components to complete its
installation:
• air terminal unit
• space temperature sensor
• transformer — 24 vac, 40 va
• two no. 10 x 1/2-in. sheet metal screws (to secure SAT
sensor to duct, if required)
• two no. 6-32 x 5/8-in. screws (to mount SPT sensor base
to electrical box)
• contactors (if required for fan or electric heat)
• supply air temperature sensor (required for terminal with
ducted heat)
• indoor air quality sensor (if required)
• relative humidity sensor (if required)
• one SPST (for each stage of electric heat, not required
for Carrier fan terminals)
• valve and actuator for hot water heat (if required)
• delta pressure airflow pickup
NOTE: When selecting an airflow pickup, it is the
designer's responsibility to select a sensor that provides the
desired output at the design airflow.
• wire
• polyethylene tubing (for pressure pickup)
• bushings (required when mounting SAT sensor in a duct
6-in. or less in diameter)
• primary air temperature sensor (if required)
SPACE TEMPERATURE SENSOR — Each zone controller requires a field-supplied Carrier space temperature sensor.
There are two sensors available for this application:
• 33ZCT55SPT, Space Temperature Sensor with Override
Button
• 33ZCT56SPT, Space Temperature Sensor with Override
Button and Set Point Adjustment
PRIMARY AIR TEMPERATURE SENSOR — A fieldsupplied, primary air temperature (PAT) sensor (part number
33ZCSENPAT) is used on a zone controller which is functioning as a Linkage Coordinator for a non CCN/Linkage compatible air source.
SUPPLY AIR TEMPERATURE (SAT) SENSOR — On
stand-alone applications or applications with ducted heat, the
zone controller must be connected to a field-supplied supply air
temperature (SAT) sensor (part number 33ZCSENSAT) to
monitor the temperature of the air delivered by the air terminal.
The zone controller will maintain the air temperature below the
maximum air temperature in ducted heating applications.
INSTALLATION
General — The zone controller is a microprocessor-based
direct digital control (DDC) controller for variable air volume
(VAV) air terminals. It can be retrofitted on units manufactured
by Carrier or other manufacturers to provide pressureindependent VAV control.
Each zone controller has the ability to function as a linkage
coordinator for systems with up to 128 zones. As a linkage coordinator, a zone controller will retrieve and provide system information to the air handling equipment and other zone controllers. A zone controller can function as a stand alone device
by installing a primary supply air sensor.
The zone controller monitors differential pressure from an
airflow pickup (or a pair of pickups) mounted on the terminal
box. It compares the resulting signal to an airflow set point in
order to provide pressure-independent control of the air passing
through the terminal.
The zone controller is connected to a wall-mounted, fieldsupplied, space temperature sensor (SPT) in order to monitor
zone temperature changes and satisfy zone demand.
On stand-alone applications or applications with heat, the
zone controller must be connected to a field-supplied supply air
temperature (SAT) sensor to monitor the temperature of the air
delivered by the air terminal.
Carrier’s Network Service Tool can be connected to the system at the SPT sensor if CCN communication wiring is run to

NOTE: Actuator clamp accepts dampers
shafts with the following characteristics:
Round — 1/4-in. to 5/8-in.
(6 to 16 mm)
Square — 1/4-in. to 7/16-in.
(6 to 11 mm)
Damper shaft must be a minimum of 1.5-in.
(38 mm) long.
Fig. 2 — Zone Controller Physical Details (33ZCFANTRM Shown)
3. Press the release button on the actuator and rotate the
clamp in the same direction that was required to close
the damper in Step 2.
4. Press the release button on the actuator and rotate the
actuator back one position graduation. Release the button and lock the actuator in this position.
5. Mount the zone controller to the terminal by sliding
the damper shaft through the actuator clamp assembly.
Secure the zone controller to the duct by installing
the screw provided through the grommet in the antirotation tab. Be sure the floating grommet is in the
center of the slot. Failure to center the grommet may
cause the actuator to stick or bind.
6. Tighten the actuator clamp assembly to the damper
shaft. Secure by tightening the two 10-mm nuts.
7. If the damper has less than 90 degrees of travel
between the fully open and fully closed positions, then
a mechanical stop must be set on the actuator. The
mechanical stop prevents the damper from opening
past the maximum damper position. To set the
mechanical stop, perform the following procedure:
a. Press the actuator release button and rotate the
damper to the fully open position.
b. Using a Phillips screwdriver, loosen the appropriate stop clamp screw.
c. Move the stop clamp screw so that it contacts the
edge of the cam on the actuator. Secure the stop
clamp screw in this position by tightening the
screw.
8. Verify that the damper opens and closes. Press the
actuator release button and rotate the damper. Verify
that the damper does not rotate past the fully open
position. Release the button and lock the damper in the
fully open position.
R E L A T I V E H U M I D I T Y S E N S O R — The
33AMSENRHS000 relative humidity sensor is required for
zone humidity control (dehumidification).
NOTE: The relative humidity sensor and CO2 sensor cannot
be used on the same zone controller.
INDOOR AIR QUALITY (CO2) SENSOR — An indoor air
quality sensor is required for optional demand control ventilation. The CGCDXSEN002A00 CO2 Sensor is an indoor,
wall mounted sensor with an LED display. The
CGCDXSEN003A00 CO2 Sensor is an indoor, wall mounted
sensor without display.
NOTE: The relative humidity sensor and CO2 sensor cannot
be used on the same zone controller.
Mount Zone Controller
LOCATION — The zone controller must be mounted on the
air terminal’s damper actuator shaft. For service access, there
should be at least 12 in. of clearance between the front of the
zone controller and adjacent surfaces. Refer to Fig. 6.
MOUNTING — Perform the following steps to mount the
zone controller:
1. Visually inspect the damper and determine the direction in which the damper shaft moves to open the
damper — clockwise (CW) or counterclockwise
(CCW). Refer to Fig. 7.
If the damper rotates CCW to open, it does not require
any configuration changes.
If the damper rotates CW to open, then the damper
actuator logic must be reversed. This is done in the
software when performing system start-up and damper
calibration test. Do not attempt to change damper rotation by changing wiring. This will upset the damper
position feedback potentiometer readings.
2. Rotate the damper shaft to the fully closed position.
Note direction of rotation.

NOTE: Do not run sensor or communication wiring in the
same conduit with line-voltage wiring.
NOTE: An accessory conduit box (part no. 33ZCCONBOX) is
available for conduit wiring connections to the zone controller.
Perform the following steps to connect the power
transformer:
1. Install the field-supplied transformer in an electrical
enclosure that conforms to NEC and local codes.
2. Connect 24 vac from the transformer as shown in the
applicable wiring diagram (Fig. 8A-J).
AIR
FLOW
CW TO OPEN, CCW TO CLOSE
Connect Airflow Pickups — The zone controller determines velocity pressure by obtaining the difference between
high and low duct pressure from two airflow pickups. The
pickups are connected to barb fittings on the zone controller
with 1/4-in. polyethylene tubing. All piping for this purpose
must conform to local codes.
Figure 9 indicates the positions of the two barb fittings.
Perform the following steps to install and connect the airflow pickups:
1. Select a location on the air handler’s supply air duct
where the airflow pickups will be installed. The location should be one where there are at least three duct
diameters of straight duct upstream of the pickups. If
this requirement is not met, stable airflow measurements may not be possible.
2. Mount the field-supplied airflow pickup(s) in the duct,
following the manufacturer's directions. Two individual pickups may be used, one for high pressure airflow
and one for low pressure airflow. A dual pickup, which
combines the two functions, may also be used. When
using individual pickups, make sure that the one for
high pressure airflow faces upstream, in the direction
the air is coming from, and the one for low pressure
airflow faces downstream, in the direction the air is
going to.
3. Use field-supplied 1/4-in. tubing (rated for the application) to connect the high pressure airflow pickup to
barb fitting P1 on the pressure transducer. At the zone
controller, the P1 fitting is on the side with the filter
installed. Be careful to avoid sharp bends in the tubing,
because malfunctions may occur if the tubing is bent
too sharply. Use at least 2 ft of tubing for reading
stability.
4. Use field-supplied 1/4-in. tubing (rated for the application) to connect the low pressure airflow pickup to
barb fitting P2 on the pressure transducer. Be careful to
avoid sharp bends in the tubing, because malfunctions
may occur if the tubing is bent too sharply. Use at least
2 feet of tubing for stability.

Fig. 7 — Damper Configuration
Connect the Power Transformer — An individual,
field-supplied, 24 vac power transformer is recommended for
each zone controller. If multiple zone controllers are powered
from one power transformer (100 va maximum for UL [Underwriters’ Laboratories] Class 2 conformance), maintain polarity
on the power input terminals. All transformer secondaries are
required to be grounded. Use only stranded copper conductors
for all wiring to the zone controller. Wiring connections must
be made in accordance with NEC (National Electrical Code)
and local codes. Ground the transformer at the transformer location. Provide an 18-gage, green, chassis ground wire at the
terminal.
The power supply is 24 vac ± 10% at 40 va (50/60 Hz).
For 33ZCVAVTRM zone controllers, the power requirement sizing allows for accessory water valves and for electric
heat contactor(s). Water valves are limited to 15 va on both
two-position and modulating hot water. The electric heat contactor(s) are limited to 10 va (holding) each.
For 33ZCFANTRM zone controllers, the power requirement sizing allows for accessory water valves and for the fan
contactor. Water valves are limited to 8 va on both two-position
and modulating hot water. The fan contactor is limited to
11 va (holding).
NOTE: If a water valve or electric heat contactor exceeds
these limits, or external contactors are required for electric
heat, then it is recommended a 60 va transformer be used.
The maximum rating for any output is 20 va.

SECONDARY DAMPER — 33ZCSECTRM
→ Install Sensors
SPACE TEMPERATURE SENSOR INSTALLATION —
A space temperature sensor must be installed for each zone
controller. There are three types of SPT sensors available from
Carrier: the 33ZCT55SPT space temperature sensor with timed
override button, the 33ZCT56SPT space temperature sensor
with timed override button and set point adjustment and the
33ZCT58SPT with liquid crystal display. See Fig. 10.
The space temperature sensor is used to measure the building interior temperature and should be located on an interior
building wall. The sensor wall plate accommodates the NEMA
standard 2 x 4 junction box. The sensor can be mounted directly on the wall surface if accpectable by local codes.
Do not mount the sensor in drafty locations such as near air
conditioining or heating ducts, over heat sources such as baseboard heaters, radiators, or directly above wall mounted lighting dimmers. Do not mount the sensor near a window which
may be opened, near a wall corner, or a door. Sensors mounted
in these areas will have inaccurate and erratic sensor readings.
The sensor should be mounted approximately 5 ft from the
floor, in an area representing the average temperature in the
space. Allow at least 4 ft between the sensor and any corner
and mount the sensor at least 2 ft from an open doorway.
Install the sensor as follows (see Fig. 11):
1. Locate the two Allen type screws at the bottom of the
sensor.
2. Turn the two screws clockwise to release the cover
from the sensor wall mounting plate.
3. Lift the cover from the bottom and then release it from
the top fasteners.
4. Feed the wires from the electrical box through the
opening in the center of the sensor mounting plate.
5. Using two no. 6-32 x 1 mounting screws (provided
with the sensor), secure the sensor to the electrical box.
6. Use 20 gage wire to connect the sensor to the controller. The wire is suitable for distances of up to 500 ft.
Use a three-conductor shielded cable for the sensor
and set point adjustment connections. The standard
CCN communication cable may be used. If the set
point adjustment (slidebar) is not required, then an
unshielded, 18 or 20 gage, two-conductor, twisted pair
cable may be used.
The CCN network service jack requires a separate,
shielded CCN communication cable. Always use separate cables for CCN communication and sensor wiring. (Refer to Fig. 12 for wire terminations.)
7. Replace the cover by inserting the cover at the top of
the mounting plate first, then swing the cover down
over the lower portion. Rotate the two Allen head
screws counterclockwise until the cover is secured to
the mounting plate and locked in position.
8. For more sensor information, see Table 1 for thermistor resistance vs temperature values.
NOTE: Clean sensor with damp cloth only. Do not use
solvents.
Wiring the Space Temperature Sensor (33ZCT55SPT and
33ZCT56SPT) — To wire the sensor, perform the following
(see Fig. 12 and 13):
1. Identify which cable is for the sensor wiring.
2. Strip back the jacket from the cables for at least
3-inches. Strip 1/4-in. of insulation from each conductor. Cut the shield and drain wire from the sensor end
of the cable.
3. Connect the sensor cable as follows:
a. Connect one wire from the cable (RED) to the
SPT terminal on the controller. Connect the other
end of the wire to the left terminal on the SEN terminal block of the sensor.
b. Connect another wire from the cable (BLACK) to
the GND terminal on the controller. Connect the
other end of the wire to the remaining open terminal on the SEN terminal block.
c. On 33ZCT56SPT thermostats, connect the remaining wire (WHITE/CLR) to the T56 terminal
on the controller. Connect the other end of the
wire to the right most terminal on the SET terminal block.
d. In the control box, install a No. 6 ring type crimp
lug on the shield drain wire. Install this lug under
the mounting screw in the upper right corner of
the controller (just above terminal T1).
e. On 33ZCT56SPT thermostats install a jumper
between the two center terminals (right SEN and
left SET).
→ Wiring the Space Temperature Sensor (33ZCT58SPT) — The
T58 space temperature sensor is wired differently than other
conventional sensors. The T58 sends all its sensor information
through the CCN bus to the zone controller that is is associated
with. The SPT sensor wiring connections are not used. The T58
sensor does not need to be directly wired to the zone controller.
The T58 sensor may be powered by a separate 24-VAC power supply or may be connected to the J1 24 VAC power terminals on the zone controller. Be sure that the polarity of the power
supply connections are consistent. For multiple devices wired to
the same power supply, all positive (+) and negative (–) terminals should be wired in the same polarity.
Wire the T58 sensor to the CCN. Connect the CCN + terminal to the RED signal wire (CCN+). Connect the CCN – terminal to the BLACK signal wire (CCN–). Connect the GND
terminal to the WHITE/CLEAR signal wire (Ground). Refer to
the T58 sensor Installation Instructions for more information
on installing and wiring the sensor.
IMPORTANT: The T58 sensor must be configured with
the bus address and device type of the zone controller
before it will broadcast temperature to the zone controller. Refer to the T58 sensor Installation Instructions for
more information on configuring the sensor.
Wiring the CCN Network Communication Service Jack —
See Fig. 12, 13, and 14. To wire the service jack, perform the
following:
1. Strip back the jacket from the CCN communication
cable(s) for at least 3 inches. Strip 1/4-in. of insulation
from each conductor. Remove the shield and separate
the drain wire from the cable. Twist together all the
shield drain wires and fasten them together using an
closed end crimp lug or a wire nut. Tape off any
exposed bare wire to prevent shorting.
2. Connect the CCN + signal wire(s) (RED) to
Terminal 5.
3. Connect the CCN – signal wire(s) (BLACK) to
Terminal 2.
4. Connect the CCN GND signal wire(s) (WHITE/CLR)
to Terminal 4.

PRIMARY AIR TEMPERATURE SENSOR INSTALLATION — A primary air temperature (PAT) sensor is used on a
zone controller which is functioning as a Linkage Coordinator
for a non CCN/Linkage compatible air source. The part number is 33ZCSENPAT. See Fig. 15.
When used on a zone controller, try to select a zone controller which will allow installation of the PAT sensor in the main
trunk, as close to the air source as possible. See Fig. 16.
SUPPLY AIR TEMPERATURE (SAT) SENSOR INSTALLATION — On terminals with heat, the SAT sensor is required. The SAT must be installed in the duct downstream
from the air terminal. The SAT sensor is also sometimes called
a duct temperature (DT) sensor. The part number is
33ZCSENSAT.
The SAT sensor probe is 6 inches in length. The tip of the
probe must not touch the inside of the duct. Use field-supplied
bushings as spacers when mounting the probe in a duct that is
6 in. or less in diameter.
If the unit is a cooling only unit, the SAT is not required.
Fig. 15 — Primary Air Temperature Sensor
(Part Number 33ZCSENPAT)
Fig. 16 — Primary Air Temperature Sensor
Installation (Unit Discharge Location)
If the unit is equipped with electric reheat, ensure that the
sensor is installed at least 2 ft downstream of the electric heater.
See Fig. 17 for the sensor location in this application.
If the unit has an octopus connected directly at the discharge, install the sensor in the octopus. If the unit has an electric heater, the two foot minimum distance between the sensor
and the heater must be maintained. See Fig. 17 for the sensor
location in this application.
Disconnect electrical power before wiring the zone controller. Electrical shock, personal injury, or damage to the zone
controller can result.
Do not run sensor or relay wires in the same conduit or raceway with Class 1 AC or DC service wiring. Do not abrade, cut,
or nick the outer jacket of the cable. Do not pull or draw cable
with a force that may harm the physical or electrical properties.
Avoid splices in any control wiring.
Perform the following steps to connect the SAT sensor to
the zone controller:
1. Locate the opening in the control box. Pass the sensor
probe through the hole.
2. Drill or punch a 1/4-in. hole in the duct downstream of
the unit, at a location that conforms to the requirements shown in Fig. 17.
3. Use two field-supplied, self-drilling screws to secure
the sensor probe to the duct. Use field-supplied bushings as spacers when installing the sensor probe in a
duct 6 in. or less in diameter.
Perform the following steps if state or local code requires
the use of conduit, or if your installation requires a cable length
of more than 8 ft:
1. Remove the center knockout from a field-supplied 4 x
2-in. junction box and secure the junction box to the
duct at the location selected for the sensor probe.
2. Drill a 1/2-in. hole in the duct through the opening in
the junction box.
3. Connect a 1/2-in. nominal field-supplied conduit
between the zone controller enclosure and the junction
box.
4. Pass the sensor probe wires through the conduit and
insert the probe in the duct. Use field-supplied bushings as spacers when installing the sensor probe in a
duct 6 in. or less in diameter.
5. Secure the probe to the duct with two field-supplied
self-drilling screws.
6. If you are extending cable length beyond 8 ft, use plenum rated, 20 AWG, twisted pair wire.
7. Connect the sensor leads to the zone controller’s wiring harness terminal board at the terminals labeled
SAT and GND.
8. Neatly bundle and secure excess wire.
→ INDOOR AIR QUALITY SENSOR INSTALLATION —
The indoor air quality (IAQ) sensor accessory monitors carbon
dioxide levels. This information is used to modify the position
of the outdoor air dampers to admit more outdoor air as
required to provide the desired ventilation rate. Two types of
sensors are supplied. The wall sensor can be used to monitor
the conditioned air space; the duct sensor monitors the return
air duct. Both wall and duct sensors use infrared technology to
measure the levels of CO2 present in the air. The wall sensor is
available with or without an LCD readout to display the CO2
level in ppm. See Fig. 18.
The sensor part number is 33ZCSENCO2. To mount the
sensor, refer to the installation instructions shipped with the accessory kit.

Figure 19 shows ventilation rates for various CO2 set points
when outside air with a typical CO2 level of 350 ppm is used.
Refer to the instructions supplied with the CO2 sensor for electrical requirements and terminal locations. The zone controller
requires 24 vac 25 va transformer to provide power to the
sensor.
5.625
(14.3)
To convert the CO2 sensor into a duct-mounted CO2 sensor,
the duct-mounted aspirator (33ZCASPCO2) will need to be
purchased.
To accurately monitor the quality of the air in the conditioned air space, locate the sensor near the return air grille so it
senses the concentration of CO2 leaving the space. The sensor
should be mounted in a location to avoid direct breath contact.
Do not mount the space sensor in drafty areas such as near
supply ducts, open windows, fans, or over heat sources. Allow
at least 3 ft between the sensor and any corner. Avoid mounting
the sensor where it is influenced by the supply air; the sensor
gives inaccurate readings if the supply air is blown directly
onto the sensor or if the supply air does not have a chance to
mix with the room air before it is drawn into the return air
stream.
To accurately monitor the quality of the air in the return air
duct, locate the sensor at least 6 in. upstream or 15 in. downstream of a 90 degree turn in the duct. The downstream location is preferred. Mount the sensor in the center of the duct.

IMPORTANT: If the sensor is mounted in the return air
duct, readjust the mixed-air dampers to allow a small
amount of air to flow past the return air damper whenever the mixing box is fully open to the outside air. If the
damper is not properly adjusted to provide this minimum airflow, the sensor may not detect the indoor-air
quality during the economizer cycle.

Indoor Air Quality Sensor Wiring — To wire the sensors
after they are mounted in the conditioned air space and return
air duct, see Fig. 20 and the instructions shipped with the sensors. For each sensor, use two 2-conductor 18 AWG twistedpair cables (unshielded) to connect the separate isolated 24 vac
power source to the sensor and to connect the sensor to the control board terminals. To connect the sensor to the control board,
identify the positive (+) PIN-8 and ground (GND) PIN-7 terminals on the sensor and connect the positive terminal to terminal
RH/IAQ and connect the ground terminal to terminal GND.
HUMIDITY SENSOR (WALL-MOUNTED) INSTALLATION — The accessory space humidity sensor is installed on
an interior wall to measure the relative humidity of the air within the occupied space. See Fig. 21.
The use of a standard 2- x 4-in. electrical box to accommodate the wiring is recommended for installation. The sensor can
be mounted directly on the wall, if acceptable by local codes.
If the sensor is installed directly on a wall surface, install the
humidity sensor using 2 screws and 2 hollow wall anchors
(field-supplied); do not overtighten screws. See Fig. 11.
Do NOT clean or touch the sensing element with chemical
solvents; they can permanently damage the sensor.
The sensor must be mounted vertically on the wall. The
Carrier logo should be oriented correctly when the sensor is
properly mounted.
DO NOT mount the sensor in drafty areas such as near heating or air-conditioning ducts, open windows, fans, or over heat
sources such as baseboard heaters, radiators, or wall-mounted
light dimmers. Sensors mounted in those areas will produce inaccurate readings.
Avoid corner locations. Allow at least 4 ft between the sensor and any corner. Airflow near corners tends to be reduced,
resulting in erratic sensor readings.
Sensor should be vertically mounted approximately 5 ft up
from the floor, beside the space temperature sensor.
For distances up to 500 feet, use a 3-conductor, 18 or 20
AWG cable. A CCN communication cable can be used,
although the shield is not required. The shield must be removed
from the sensor end of the cable if this cable is used. See
Fig. 22 for wiring details.
→
The power for the sensor is provided by the control board.
The board provides 24 vdc for the sensor. No additional power
source is required.
To wire the sensor, perform the following:
1. At the sensor, remove 4-in. of jacket from the cable.
Strip 1/4-in. of insulation from each conductor. Route
the cable through the wire clearance opening in the
center of the sensor. See Fig. 22.
2. Connect the RED wire to the sensor screw terminal
marked (+).
3. Install one lead from the resistor (supplied with the
sensor) and the WHITE wire, into the sensor screw terminal marked (–). After tightening the screw terminal,
test the connection by pulling gently on the resistor
lead.
4. Connect the remaining lead from the resistor to the
BLACK wire and secure using a closed end type crimp
connector or wire nut.
5. Using electrical tape, insulate any exposed resistor
lead to prevent shorting.
6. At the control box, remove the jacket from the cable
and route the RED conductor over to the left side of
the control board. Route the remaining conductors to
the right side of the control board.

Connect the CCN Communication Bus — The
zone controllers connect to the bus in a daisy chain arrangement. The zone controller may be installed on a primary CCN
bus or on a secondary bus from the primary CCN bus. Connecting to a secondary bus is recommended.
At 9,600 baud, the number of controllers is limited to 128
zones maximum, with a limit of 8 systems (Linkage Coordinator configured for at least 2 zones). Bus length may not exceed
4000-ft, with no more than 60 devices on any 1000-ft section.
Optically isolated RS-485 repeaters are required every 1000 ft.
At 19,200 and 38,400 baud, the number of controllers
is limited to 128 maximum, with no limit on the number of
Linkage Coordinators. Bus length may not exceed 1000 ft.
The first zone controller in a network connects directly to
the bridge and the others are wired sequentially in a daisy chain
fashion. Refer to Fig. 25 for an illustration of CCN Communication Bus wiring.
The CCN Communication Bus also connects to the zone
controller space temperature sensor. Refer to the Install the
Sensors section for sensor wiring instructions.
COMMUNICATION BUS WIRE SPECIFICATIONS —
The Carrier Comfort Network (CCN) Communication Bus
wiring is field-supplied and field-installed. It consists of
shielded three-conductor cable with drain (ground) wire. The

NOTE: Conductors and drain wire must be at least 20 AWG
(American Wire Gage), stranded, and tinned copper. Individual conductors must be insulated with PVC, PVC/nylon, vinyl, teflon, or
polyethylene. An aluminum/polyester 100% foil shield and an outer
jacket of PVC, PVC/nylon, chrome vinyl, or Teflon with a minimum
operating temperature range of –20° C to 60° C is required.
Connect the Outputs — Wire the zone controller’s
outputs (fan, staged heat, valves) as shown in the applicable
wiring diagrams in Fig. 8A-J.
Modulating Baseboard Hydronic Heating — Install the water valve on the leaving water end of the baseboad
heater. See Fig. 24. Observe the fluid flow direction when
mounting the valve. Be sure to properly heat sink the valve and
direct the flame away from the actuator and valve body when
sweating the valve connections. Install the leaving water temperature sensor (33ZCSENCHG) on the hydronic heating coil
as shown. The sensor accommodates nominal copper pipe
from 1/2 to 1-in. (OD sizes from 5/8 to 1.125 in.). It should be
secured to the pipe with the clamp supplied. If piping is larger
than 1-in. nominal size, a field-supplied clamp must be used.
Use fiberglass pipe insulation to insulate the sensor assembly.
Refer to Fig. 8C and 8H to wire the modulating water valve
and the sensor to the zone controller. Connect the leaving water
temperature sensor to the controller using the wiring connections shown for the SAT sensor. (NOTE: The leaving water
temperature sensor replaces the SAT sensor in this application.)
Use 18 or 20 AWG wire for all connections. The water valve
actuator housing may be used as a junction box if the leaving
water temperature sensor cable is not long enough and the sensor cable must be extended to reach the controller.
For modulating hydronic heating applications, the default
configuration must be changed to properly control the valve.

START-UP
3. Check that all air duct connections are tight.
4. At the air terminals, check fan and system controls for
proper operation. Verify that actuator screws are properly tightened.
5. At the air terminals, check electrical system and connections of any optional electric reheat coil. If hot
water reheat is used, check piping and valves against
job drawings.
6. At the air terminals, make sure that all balancing
dampers at box outlets are in the fully open position.
7. If using an air handler with field-installed controls,
make sure controls and sensors have been installed and
wired per manufacturer installation instructions.
8. At air handlers, verify that the motor starter and, if
applicable, the Hand/Off/Auto (HOA) switch are
installed and wired.
NOTE: The HOA switch must be in the Off position.
Use the Carrier network communication software to start up
and configure the zone controller.
All set-up and set point configurations are factory-set and
field-adjustable.
Changes can be made using the ComfortWORKS® software, ComfortVIEW™ software, or Network Service Tool.
The Network Service Tool is a portable interface device that allows the user to change system set-up and set points from a
zone sensor or terminal control module. During start-up, the
Carrier software can also be used to verify communication
with each zone controller.
For specific operating instructions, refer to the literature
provided with the software.
Perform System Check-Out
1. Check correctness and tightness of all power and communication connections.
2. Check that all air terminals, ductwork, and zone controllers are properly installed and set according to
installation instructions and job requirements.

elliptical damper inlet is supplied, then enter the inlet
size in square inches in the Inlet Area decision.
5. If the terminal damper closes in the CW direction, then
no adjustment is required. Otherwise, locate the
damper direction configuration decision (CW Rotation) and toggle the value to OPEN by using the space
bar. This configuration decision is also located on the
Terminal Service Configuration screen.
6. After entering the area and rotation direction, verify
operation of the damper. From the service tool Diagnostic, Maintenance Screen, select the Zone Air
Balance/Commissioning Table and force the Commissioning Mode point to Enable. Then select the
Damper/Transducer Cal point and force this point to
Enable. The controller automatically tests the actuator
by fully closing the damper.
It checks the fully closed position to determine if the
control was properly mounted. It then opens the
damper. The control scales the actual actuator travel
range used to a 0 to 100% open value. Finally the control will close the damper, test, and zero the pressure
transducer. When completed, the control automatically
removes the force from the Damper/Transducer Cal
point. If a failure occurs at any point during the testing,
the Auto-Calibration point at the bottom of the screen
will indicate ALARM and the test will be aborted.
7. The actuator stroke has now been calibrated for the
proper rotation.
9. Check to be sure the area around the air handler(s) is
clear of construction dirt and debris.
10. Check that final filters are installed in the air handler(s). Dust and debris can adversely affect system
operation.
11. Verify that the zone controller and the air handler controls are properly connected to the CCN bus.
Before starting the air source fan, make sure that dampers
at the system’s air terminals are not fully closed. Starting
the fan with dampers closed will result in damage to the
system ductwork.
12. Remember to utilize good duct design and to provide
sufficient straight duct at the inlet of the box. A minimum of three times the inlet size is recommended.
Network Addressing — Use the following method
when all the zone controllers are installed and powered, and the
SPT sensors are wired and functioning properly. This method
can be used if no addresses have been set previously. The address of an individual zone controller may be set by using the
address search function on the Service Tool software when it is
directly connected to the service port of the zone controller and
the CCN bus is disconnected. This is the standard method of
setting the address.
Addresses may also be set using the Service Tool Address
Search Function if the zone controller is isolated from the CCN
bus.
Each zone controller will default to an address of 0, 140
when its application software is initially loaded. Since multiple
controllers will be on the same bus, a unique address must be
assigned to each controller before the system can operate properly. The assignment of controller addresses will be performed
through software by using the Address Search function of the
Network Service Tool, as follows:
1. The software recognizes that the Zone Controller's address, stored in the zone controller memory, has not been
written yet (this will be true when the unit is first powered
up on the job, or after a jumper-initiated reset).
2. Press the override button on the SPT (terminals J4-14 and
J4-12 are shorted) for 1 to 10 seconds.
3. The zone controller address changes from 0, 140 to 239,
239 for a period of 15 minutes.
→ 4. Use Network Service Tool to change the address from
239, 239 to a valid system address within 15 minutes.
NOTE: If the address is not changed from 239, 239 to
a valid system address within 15 minutes, the controller will revert to address 0, 140 and use of the override
button will cause the address function to repeat. The
operator MUST actively set the address even if the
final desired address is 0, 140.
Airflow Check — After the damper transducer calibration
has been performed, the terminal is ready for an airflow check.
To perform airflow check, make sure Terminal Type, Primary
Inlet Size, and Probe Multiplier settings on the Terminal Service Configuration screen are configured. If all of the terminals
were installed with the dampers open, it is acceptable to start
the fan at this time. If it becomes difficult for the air source to
provide the necessary static pressure for airflow testing, it may
be necessary to calibrate the damper transducer for a majority
of terminals and check temperatures and set points to be sure
most will be controlling to less than maximum CFM when the
air source is started.
When the system fan is running and the static pressure is
fairly stable access the Zone Air Balance/Commissioning table
and force the Commissioning Mode Point to Enable. The system is now ready to enable maximum CFM and check if the
airflow controls correctly with the maximum CFM set point.
Read the Zone Air Balance/Commissioning table section on
page 47 which describes the Zone Air Balance/Commissioning
table and what adjustments can be made from this screen. If the
maximum airflow function is working properly, the user can
stop here and leave the rest of the airflow calibration for the air
balance contractor.
If working with the air balance contractor, proceed with the
minimum airflow calibration at this time. If this terminal is fan
powered or the terminal was installed with heat, and the heat
configuration was already performed, continue with the fan
and heat test while the Zone Air Balance/Commissioning table
is still being displayed.
Initial Operation and Test — Perform the following
procedure:
1. Apply 24 vac power to the control.
2. Connect the service tool to the phone jack service port
of the controller.
3. Using the service tool, upload the controller from
address assigned in Network Addressing section
above.
4. From the Terminal Service Configuration screen,
properly configure the damper type and inlet size. If a
round inlet is used, then enter the size directly in the
Inlet Diameter decision. If a square, rectangular, or

Fan and Heat Configuration and Test — Perform the following procedure to configure and test the fan and
heat:
1. Display the Terminal Service Configuration screen to
make sure the proper Terminal Type and Heat Type are
configured. See the Configuration section to answer
questions about the individual configurations.
2. From the Diagnostics Maintenance Screen select the
Zone Air Balance/Commissioning table.
3. Force the Commissioning Mode to Enable.
30
4. If the terminal is a parallel or series powered fan box,
force the Fan Override to Enable. If the damper is open
it may have to be repositioned to the proper position
depending on the box type. Damper percent change
will be displayed. After the damper is positioned correctly, the fan relay should energize and the fan should
run for a few seconds.
5. Make sure the fan runs and the Fan Override decision
returns to disabled to ensure the fan is wired correctly
for proper operation.
6. Force the Heating Override to Enable. If the unit is a
single duct unit, this must be done with the primary
terminal at reheat set point. The damper will modulate
to maintain the terminal reheat CFM. The heat outputs
will be commanded to provide maximum heat. If the
unit is a fan powered terminal, the fan must be on.
NOTE: The CFM settings can be found under service configuration in the table AIRFLOW.

CONFIGURATION
SCREEN — The Linkage Coordinator Configuration screen
allows the user to set the linkage coordinator configuration settings. See Table 6.
Linkage Master Zone — This decision defines if the zone
controller will function as a Linkage Coordinator (Linkage
Master) for itself and other zones.
If the zone controller is to use a supply air sensor for standalone operation, this configuration must be configured to No
and the number of Zones to 1.
If the zone controller will use its primary air sensor to determine the air handler mode for a number of zone controllers,
configure this configuration to Yes, input the number of zones,
and leave the air source decisions at the default values of zero.
If this zone controller will communicate linkage information with an air source, configure this configuration to Yes. The
number of zones must be configured and the address of the air
source entered.
Linkage
Master Zone:
Range
Yes/No
Default Value
No
Number of Zones — This decision defines the number of zone
controllers (including itself) for the Linkage Coordinator to
scan and include as part of the average temperature, set points,
and occupancy information to the air source. The address of the
zone controller functioning as a Linkage Coordinator must be
larger than the number of zones configured. The zone controller will scan addresses less than its own, including information
for as many zones as are configured. Other zone controller configured as linkage coordinators will also be included, so it is
possible to have zones scanned by more than one linkage coordinator. Therefore care must be taken in addressing to prevent
overlapping systems, unless overlapping systems is necessary.
In large buildings the use of bridges and multiple busses is recommended to improve communication and provide system
differentiation.

Static Pressure Reset — Air systems designed with diversity
(airflow required with all zones at maximum cfm exceeds design capacity of air handler) are capable of providing enough
CFM to all zones on days when conditions meet the demand at
design static. At other times, the air system does not require the
design static to meet the load requirements.
Static pressure reset allows the static pressure set point on
the air source to be reset whenever the system load is reduced
from the design maximum. The zone controller will then monitor damper positions. When the system dampers are modulating at lower damper positions due to the higher static, the static
pressure will then be reset to a lower value allowing the dampers to open more. This allows the system to automatically make
adjustments to the static pressure and optimize performance of
the fan which will reduce energy consumption.
The linkage coordinator monitors the position of all dampers in its system. When any zone’s maximum damper position
reaches the Reset Maximum Damper Position, the linkage coordinator will reduce the value of the reset variable.
The Maximum Damper Position and Static Pressure Reset
values can be viewed on the Linkage maintenance screen.
NOTE: The static pressure set point configured in the air
source should be the desired maximum (zero reset) static
pressure.

*To use Static Pressure Reset with a Comfort System
AirManager, configure the variable name to SPRESET.
Currently, to make use of the static reset information, a custom program must be written in a Comfort Controller to read
the reset value and change the set point of the static pressure
control in the air source. Use this configuration to create a variable name (Static Pressure Reset Value). See the application
manual for information about creating this custom program.
The Comfort System AirManager™ control has an internal
SPRESET variable which functions to accept the static pressure reset value from the linkage coordinator (refer to the Air
Manager manual for configuration setup).
→ CCN Linkage Data — A zone controller configured as a
Linkage master has the ability to poll its slaves and collect the
high, low or average value of any variable within its slaves.
Once the high, low or average is determined, the master can
then transfer that value to a configured bus number, element
number and point name. Typically this feature is used to determine a system’s highest indoor air quality reading.
In order to utilize this feature the CCN Variable Name being
collected from the slaves must be supplied. The data transfer
rate must be specified and whether the high, low, or average
value is being determined. After the value has been determined, a valid point name and CCN address to transfer the
value to must be entered.

→ Temp Sensor Grouping — Each ComfortID™ controller has
the capability to broadcast the associated space temperature
sensor’s data or listen to another controller’s sensor data over
the network. All controllers sharing the same sensor must be
installed on the same CCN bus.
There are three configuration decisions that must be configured in order to share sensors. The Temp Sensor Mode is used
to specify if a controller will use its own local sensor, broadcast
its local sensor, or listed to another controller’s sensor broadcast. The Temp Sensor Config is used to specify if the controller is sharging the space temperature information only or the
space temperature and temperature offset slidebar information.
The Broadcast Device ID decision is used to specify which
controller number a zone will listen for when configured to
receive another controller’s broadcast.

OCCUPANCY CONFIGURATION SCREEN — The Occupancy Configuration screen is used to set the occupied
schedule. See Table 7.
Manual Override Hours — The Manual Override Hours decision is used to command a timed override by entering the number of hours the override will be in effect.
If the occupancy schedule is occupied when this number is
downloaded, the current occupancy period will be extended by
the number of hours downloaded.
If the current occupancy period is unoccupied when the occupancy override is initiated, the mode will change to occupied
for the duration of the number of hours downloaded.
If the occupancy override will end after the start of the next
occupancy period, the mode will transition from occupancy
override to occupied without becoming unoccupied, and the
occupancy override timer will be reset.
An active occupancy override or a pending occupancy override may be canceled by downloading a zero to this configuration. Once a number other than zero has been downloaded to
this configuration any subsequent downloads of any value other than zero will be ignored by the zone controller.

should be configured for backup pressure dependent operation,
if an operating problem with the pressure transducer occurs.
IMPORTANT: Pressure dependent settings are
included for use only in the event of a pressure transducer failure. The inclusion of these configuration settings does not indicate that Carrier is endorsing this

The calibration gain is used for the fine tuning adjustments
which might need to be made to the airflow calculation. This
number is calculated automatically by the zone controller after
input to the air balance maintenance screen, or it can be input
manually at this screen. For ease of use it is recommended to
use the Air Balance Maintenance screen to determine this number. The Air Balancing Maintenance screen will cause the value to be updated during the balancing procedure.
If the Calibration Gain must be configured manually, it is
determined as a percentage up or down that the CFM indicated
will be offset. A number of .95 will cause the maximum airflow calculated to be reduced to 95% of the value. A Calibration Gain of 1.00 will cause no change. A number of 1.05
would cause readings to become 5% higher.
The Calibration Gain is adjusted on the Air Balance Maintenance screen when performing the Maximum Airflow calibration and will have the greatest effect on the airflow at maximum CFM. Any error in reading at minimum airflow is adjusted by calculating the Offset configuration value. After
performing the air balance using the Air Balance Maintenance
screen it is a good idea to upload and save the Calibration Gain
and Offset values.
Calibration Gain: Range
0.000 to 9.999
Default Value
1.000
Offset — The Offset configuration is included for precision
applications where the minimum airflow is critical and not zero. This configuration indicates the amount of CFM the transducer is off by, at minimum airflow, during the minimum airflow test on the air balance screen. This configuration should
not be used to zero the airflow transducer since an auto zero
test is included on the air balance screen and is also automatically performed each time the equipment fan is disabled (or
every 72 hours for systems which run the fan continuously).
Probe Multiplier — This configuration is used to input a factor
for the velocity pressure probe characteristics installed in the
inlet. All averaging probes will have some aerodynamic characteristics which will amplify the pressure difference read at
the inlet of the terminal.
The default value of 2.443 is the correct value to use if the
probe is a Carrier probe in a 35 of 45 Series terminal. The formula for calculating velocity using an Ideal probe is:
Velocity = 4005* SQRT (Velocity Pressure)
Most manufactures will provide a probe constant for the
probe supplied. For example, Velocity = 2213*SQRT(Velocity
Pressure). To calculate the number to input in this decision
(Probe Multiplier) use the formula. (4005/2213)2 = 3.3. So you
would use 3.3 in place of 2.443 for a probe with a probe constant of 2213.
An easy way to determine the probe constant for a probe
without documentation is to measure the velocity pressure with
a Magnahelic gage. Open the damper and adjust the static pressure until you have one inch of velocity pressure on the Magnahelic gage. Measure the total CFM of air being produced. The
CFM just measured divided by the inlet area in feet should
equal the probe constant for the formula. Velocity = (CFM just
measured/ inlet area) * SQRT (1.0). Now use the constant that
was empirically derived to determine the probe multiplier
(4005/(CFM at 1.0 in. wg/inlet area))2 = Probe Multiplier.
Probe Multiplier: Range
0.250 to 9.999
Default Value
2.443
Calibration Gain — Air terminal testing by industry standards
is done with straight duct, upstream of the terminal. Since some
applications do not get installed in this manner, the actual airflow from the terminal at balancing may not equal the reading
from the zone controller.

VAV Central Heating — The VAV Central Heating configuration is used if the air source has the ability to provide heat and
the terminal is required to modulate, using the heat minimum
and heat maximum airflows, when the air source is in the heat
mode. If this variable is set to No, the terminal will use its
available local heat to heat the zone at all times.
VAV Central
Heating:
Range
No/Yes
Default Value
Yes
Heating Loop Parameters — The heating loop gains and start
value define how the terminal will respond to deviations in
measured space temperature in order to control to the heat set
point.
The Proportional Gain is calculated each time the space
temperature is compared to the heat set point. As the error
from set point goes to zero, the Proportional Gain will also go
to zero.
The Integral Gain is a running summation of all integral
terms since the loop started. This has the affect of trimming off
any offset from set point which might occur if only the Proportional Gain existed. Normally a proportional loop with no Integral Gain would require frequent adjustments of the starting
value to eliminate the offset as loading conditions on the room
change.
The Derivative Gain is not needed. This term tends to nullify large changes in the Proportional Gain for dampened
response.
Heating Loop Parameters
Proportional Gain: Range
00.0 to 99.9
Default Value
8.0
After performing the air balance testing using the Air Balance
Maintenance screen it is a good idea to upload and save the
Calibration gain and Offset values. The cfm will be offset by
the value entered in the Minimum Cfm variable and will zero
at the value entered in the Maximum Cfm variable. There will
be a linear relationship between the two set points.
Offset:
Units
cfm
Range
-250 to 250
Default Value
0
Damper Loop Parameters — The loop gains and start value
define how the terminal will respond to deviations in measured
CFM in order to control to the airflow set point.
The Proportional Gain is calculated each time the airflow is
compared to the active airflow set point. As the error from set
point goes to zero, the proportional term will also go to zero.
The Integral Gain is a running summation of all integral
terms since the loop started. This has the effect of trimming off
any offset from the set point which might occur, if only the proportional term existed. Normally a proportional loop with no
integral term would require frequent adjustments of the starting
value to eliminate the offset as static pressure and other conditions change.
The Derivative Gain is not needed. The Derivative Gain
would tend to nullify large changes in the Proportional Gain for
dampened response. These large changes in the Proportional
Gain do not tend to happen for this type of control.

Probe Multiplier — This configuration is used to input a factor for the velocity pressure probe characteristics installed in

characteristics which will amplify the pressure difference read
at the inlet of the terminal. The default of 2.443 is the correct
value to use if the probe is a Carrier probe in a 35 or 45 Series
terminal.
The formula for calculating velocity using an Ideal probe is:
Velocity = 4005* SQRT (Velocity Pressure)
Most manufactures will provide a probe constant for the
probe supplied. For example, Velocity = 2213*SQRT(Velocity
Pressure). To calculate the number to input in this decision
(Probe Multiplier) use the formula. (4005/2213)2 = 3.3. So you
would use 3.3 in place of 2.443 for a probe with a probe constant of 2213.
An easy way to determine the probe constant for a probe
without documentation is to measure the velocity pressure with
a Magnahelic gage. Open the damper and adjust the static pressure until you have one inch of velocity pressure on the Magnahelic gage. Measure the total CFM of air being produced. The
CFM just measured divided by the inlet area in feet should
equal the probe constant for the formula. Velocity = (CFM just
measured/inlet area) * SQRT (1.0). Now use the constant that
was empirically derived to determine the probe multiplier
(4005/(CFM at 1.0 Inch/Inlet area))2 = Probe Multiplier.

Clockwise Rotation — This configuration is used to define
what effect a clockwise rotation of the actuator will have on the
damper. If the actuator rotates clockwise to closed position, the
configuration should be set to Close. If the actuator rotates
clockwise to open, the configuration should be set to open.
This configuration is used to change the rotation of the actuator
so that the damper transducer calibration will work properly.
The actuator does not have to be reinstalled nor any switches
changed to reverse the action.

Maximum Cooling Airflow Calibration — By enabling the
Maximum Cooling Airflow Calibration, the Maximum Cooling Airflow from the set point schedule will be made the Airflow CFM Set Point. The zone controller will modulate the
damper to control to this set point. The actual airflow, damper
position, and velocity pressure readings will be displayed.
If the set point is not correct, it may be changed from this
screen by forcing the airflow set point to the desired value. The
value will be written to the set point schedule in the Maximum
Cool CFM set point, and the zone controller will begin to control to the new value.
The airflow can be measured using test and balance equipment and compared to the actual reading on the screen. If the
value measured requires adjustment to the value on the screen,
force the value on the screen to the value measured. The zone
controller will take the value and calculate a new calibration
gain which will be shown at the bottom of the screen. The new
value will be automatically loaded into the Service Configuration table.

Damper Actuator/Transducer Calibration — The Damper
Actuator Transducer calibration is the first calibration which
should be performed on a newly installed actuator. The zone
controller will command the actuator to close and read the
feedback potentiometer to determine the zero position of the
damper. It will then command the damper to fully open. The
zone controller will read the potentiometer to determine the
maximum open position. Damper positions from closed to
maximum open will be scaled to read 0 to 100% for the damper position.
The zone controller will then close the damper and open it
once more to zero calibrate the airflow sensor. The entire

Calibration Gain — Air terminal testing by industry standards
is done with straight duct, upstream of the terminal. Since most
applications are not installed in this manner, the actual airflow
from the terminal, at balancing, may not equal the reading from
the zone controller.
The Calibration Gain is used for making fine tuning adjustments to the airflow calculation. This number is calculated automatically by the zone controller after input to the air balance
maintenance screen. The Calibration Gain can also be entered
manually in the service configuration CONFIG screen.
A number of .95 entered into the Calibration Gain variable
will cause the maximum airflow to be reduced to 95% of the
calculated value. A number of 1.05 would cause readings to
become 5% higher. The Calibration Gain is adjusted on the Air
Balance maintenance screen when performing the Maximum
Airflow Calibration and will have the greatest affect on the airflow at maximum CFM.
After performing the air balance procedure using the air balance maintenance screen, it is recommended to upload and
save the Airflow Configuration, Calibration Gain, and Offset
settings.

The Offset configuration is included for precision applications where the minimum airflow is critical and not zero. The
Offset configuration should not be used to zero the airflow
transducer since an auto zero test is included in the normal
function of the zone controller and is automatically performed
each time the equipment fan is disabled (or every 72 hours for
systems which run the fan continuously). After performing air
balance testing using the Air Balance Maintenance screen, it is
a good idea to upload and save the Airflow set points, Calibration Gain, and Offset values.
