SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should
install, repair, or service air-conditioning equipment.
Untrained personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All other
operations should be performed by trained service personnel.
When working on air-conditioning equipment, observe precautions in the literature, tags and labels attached to the unit, and
other safety precautions that may apply.
Follow all safety codes. Wear safety glasses and work
gloves. Use quenching cloth for unbrazing operations. Have
fire extinguishers available for all brazing operations.
Disconnect gas piping from unit when leak
testing at pressure greater than 1/2 psig. Pressures greater than 1/2 psig will cause gas valve
damage resulting in hazardous condition. If
gas valve is ever subjected to pressure greater
than 1/2 psig, it must be replaced before use.
When pressure testing field-supplied gas piping at pressures of 1/2 psig or less, a unit connected to such piping must be isolated by
manually closing the gas valve(s).
Before performing service or maintenance operations on
unit, turn off main power switch to unit, install lockout tag.
Ensure voltage listed on unit data plate agrees with electrical supply provided for the unit. Electrical shock could
cause personal injury.
INSTALLATION
Unit is shipped in the vertical discharge configuration. To
convert to horizontal configuration, remove screws from side
duct opening covers and remove covers. Using the same
screws, install covers on vertical duct openings with the insulation side down. Seals around duct openings must be tight. See
Fig. 1.
Confirm before installation of unit that voltage, amperage
and circuit protection requirements listed on unit data plate
agree with power supply provided.
Step 1 — Provide Unit Support
ROOF CURB — Assemble and install accessory roof curb in
accordance with instructions shipped with curb. See Fig. 2. Install insulation, cant strips, roofing felt, and counter flashing as
shown. Ductwork must be attached to curb. If gas or electrical
connections are to be routed through the curb, attach the accessory thru-the-curb service connection plate to the roof curb in
accordance with the accessory installation instructions. Connections must be installed before unit is set in roof curb.
IMPORTANT: The gasketing of the unit to the roof curb is
critical for a watertight seal. Install gasket supplied with the
roof curb as shown in Fig. 2. Improperly applied gasket can
also result in air or water leaks and poor unit performance.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Tab 1a 6a
Curb should be level. Unit leveling tolerances are shown in
Fig. 3. This is necessary for unit drain to function properly. Refer to Accessory Roof Curb Installation Instructions for additional information as required.
If gas or electrical connections are to be routed through the
bottom of the unit, attach accessory thru-the-bottom service
connections to the basepan in accordance with the accessory
installation instructions.
ALTERNATE UNIT SUPPORT — When the curb or adapter
cannot be used, support unit with sleepers using unit curb or
adapter support area. If sleepers cannot be used, support long
sides of unit with a minimum of three 4-in. x 4-in. pads, 2 at the
corners and one at the unit’s center of gravity. If more than
3 pads are used, equally space the pads along the sides of the
unit.
SLAB MOUNT (Horizontal Units Only) — Provide a level
concrete slab that extends a minimum of 6 in. beyond unit cabinet. Install a 6-in. gravel apron in front of condenser coil air
inlet to prevent grass and foliage from obstructing airflow.
NOTE: Horizontal units may be installed on a roof curb if
required.
A minimum clearance is not required around ductwork.
Cabinet return-air static pressure (a negative condition) should
not exceed 0.35 in. wg with economizer or 0.45 in. wg without
economizer.
These units are designed for a minimum heating operation
continuous return-air temperature of 50 F (dry bulb), or an intermittent operation down to 45 F (dry bulb), such as when
used with a night set-back thermostat.
To operate at lower return-air temperatures, a field-supplied
outdoor-air temperature control must be used to initiate both
stages of heat when the temperature is below 45 F. Indoor comfort may be compromised when these lower air temperatures
are used with insufficient heating temperature rise.
Step 3 — Install External Trap for Condensate
Drain — The unit’s 3/4-in. condensate drain connections are
located on the bottom and side of the unit. Unit discharge connections do not determine the use of drain connections; either
drain connection can be used with vertical or horizontal
applications.
When using the standard side drain connection, make sure
the plug (Red) in the alternate bottom connection is tight before
installing the unit.
To use the bottom drain connection for a roof curb installation, relocate the factory-installed plug (Red) from the bottom
connection to the side connection. See Fig. 4. The piping for
the condensate drain and external trap can be completed after
the unit is in place. See Fig. 5.
All units must have an external trap for condensate drainage. Install a trap a minimum of 4-in. deep and protect against
freeze-up. If drain line is installed downstream from the external trap, pitch the line away from the unit at 1 in. per 10 ft of
run. Do not use a pipe size smaller than the unit connection
(3/4 in.).
The center drain plug looks like a star connection, however
it can be removed with a 1/2 in. socket drive extension.
Step 2 — Field Fabricate Ductwork — Secure all
ducts to roof curb and building structure on vertical units. Do not
connect ductwork to unit. For horizontal applications, fieldsupplied flanges should be attached to horizontal discharge
openings and all ductwork secured to the flanges. Insulate and
weatherproof all external ductwork, joints, and roof openings
with counter flashing and mastic in accordance with applicable
codes.
Ducts passing through an unconditioned space must be insulated and covered with a vapor barrier.
If a plenum return is used on a vertical unit, the return
should be ducted through the roof deck to comply with applicable fire codes.

Step 4 — Rig and Place Unit — Inspect unit for transportation damage. File any claim with transportation agency.
Keep unit upright and do not drop. Spreader bars are not required if top crating is left on unit. Rollers may be used to move
unit across a roof. Level by using unit frame as a reference. See
Tables 1A and 1B and Fig. 6 for additional information. Operating weight is shown in Tables 1A and 1B and Fig. 6.
Lifting holes are provided in base rails as shown in Fig. 6,
7A and 7B. Refer to rigging instructions on unit.
Flue vent discharge must have a minimum horizontal clearance of 48 in. from electric and gas meters, gas regulators, and
gas relief equipment.
Flue gas can deteriorate building materials. Orient unit so
that flue gas will not affect building materials.
Adequate combustion-air space must be provided for proper
operation of this equipment. Be sure that installation complies
with all local codes and Section 5.3, Air for Combustion
and Ventilation, NFGC (National Fuel Gas Code), ANSI
(American National Standards Institute) Z223.1-latest year and
addendum Z223.1A-latest year. In Canada, installation must be
in accordance with the CAN1. B149.1 and CAN1.B149.2
installation codes for gas burning appliances.
All panels must be in place when rigging and lifting. Unit
is not designed for handling by a fork truck. Damage to
unit may result.
POSITIONING — Maintain clearance around and above unit
to provide minimum distance from combustible materials,
proper airflow, and service access. See Fig. 7A and 7B Notes.
Do not install unit in an indoor location. Do not locate unit air
inlets near exhaust vents or other sources of contaminated air.
Be sure that unit is installed so that snow will not block the
combustion intake or flue outlet.
Unit may be installed directly on wood flooring or on Class
A, B, or C roof-covering material when roof curb is used.
Although unit is weatherproof, guard against water from
higher level runoff and overhangs.
Position unit on roof curb so that the following clearances
are maintained: 1/4-in. clearance between roof curb and base
rails on each side and duct end of unit; 35/16-in. clearance
between roof curb and condenser section end. (See Fig. 2,
section C-C.)
Locate mechanical draft system flue assembly at least 48 in.
from an adjacent building or combustible material. When unit
is located adjacent to public walkways, flue assembly must be
at least 7 ft above grade.

Step 5 — Install Flue Hood — Flue hood is shipped
screwed to the burner compartment access panel. Remove
from shipping location and, using screws provided, install flue
hood and screen in location shown in Fig. 8.
Step 6 — Install Gas Piping — Unit is equipped for
use with type of gas shown on nameplate. Refer to local
building codes, or in the absence of local codes, to
ANSI Z223.1-latest year and addendum Z223.1A-latest year
entitled National Fuel Gas Code. In Canada, installation must
be in accordance with the CAN1.B149.1 and CAN1.B149.2
installation codes for gas burning appliances when installing
gas piping.
For natural gas applications, gas pressure at unit gas connection must not be less than 4.0 in. wg (5.0 in. wg in high heat
units) or greater than 13.0 in. wg while unit is operating.
For liquid propane applications, the gas pressure must not be
less than 5.0 in. wg or greater than 13.0 in. wg at the unit
connection.
Size gas supply piping for 0.5 in. wg maximum pressure
drop. Do not use supply pipe smaller than unit gas connection.

Fig. 9 — Gas Piping Guide (With Accessory
Thru-the-Curb Service Connections)
When connecting gas piping to gas valve inlet, use properly sized back-up wrench to prevent valve damage.
FIELD POWER SUPPLY — All units except 208/230-v
units are factory wired for the voltage shown on the nameplate.
If the 208/230-v unit is to be connected to a 208-v power supply, the transformer must be rewired by moving the black wire
from the 230-v 1/4-in. spade terminal on the transformer and
connecting it to the 208-v 1/4-in. spade terminal from the
transformer.
Refer to unit label diagram for additional information. Pigtails are provided for field service.
When installing units, provide a disconnect per NEC. Use
copper conductors only when splice connectors are used.
All field wiring must comply with NEC and local requirements. In Canada, electrical connections must be in accordance
with CSA (Canadian Standards Association) C22.1 Canadian
Electrical Code Part One.
Install conduit through side panel openings indicated in
Fig. 7A and 7B. Route power lines through connector to terminal connections as shown in Fig. 10.
On 3-phase units, voltages between phases must be balanced within 2% and the current within 10%. Use the formula
shown in Tables 2A-2D, Note 2 to determine the percentage of
voltage imbalance. Operation on improper line voltage or excessive phase imbalance constitutes abuse and may cause damage to electrical components. Such operation would invalidate
any applicable Carrier warranty.
NOTE: If field-installed thru-the-bottom connections are used,
refer to the accessory installation instructions for power wiring
and gas connections. Refer to Fig. 7A and 7B for drilling holes
in basepan.
FIELD CONTROL WIRING — Install a Carrier-approved
accessory thermostat assembly according to installation instructions included with the accessory. Locate thermostat
assembly on a solid wall in the conditioned space to sense average temperature in accordance with thermostat installation
instructions.
NOTE: For wire runs up to 50 ft, use no. 18 AWG (American
Wire Gage) insulated wire (35 C minimum). For 50 to 75 ft,
use no. 16 AWG insulated wire (35 C minimum). For over
75 ft, use no. 14 AWG insulated wire (35 C minimum). All
wire larger than no. 18 AWG cannot be directly connected to
the thermostat and will require a junction box and splice at the
thermostat.
Support gas piping as shown in the table in Fig. 9. For example, a 3/4-in. gas pipe must have one field-fabricated support
beam every 8 ft.
See Fig. 9 for typical pipe guide and locations of external
manual gas shutoff valve.
NOTE: If field-installed thru-the-bottom connections are used,
refer to the accessory installation instructions for power wiring
and gas connections. Refer to Fig. 7A and 7B for drilling holes
in basepan.
Step 7 — Make Electrical Connections
Unit cabinet must have an uninterrupted, unbroken electrical ground to minimize the possibility of personal injury if
an electrical fault should occur. This ground may consist of
electrical wire connected to unit ground lug in control compartment, or conduit approved for electrical ground when
installed in accordance with NEC (National Electrical
Code), ANSI/NFPA (National Fire Protection Association), latest edition, and local electrical codes. Do not use
gas piping as an electrical ground. Failure to follow this
warning could result in the installer being liable for personal injury of others.

Route thermostat cable or equivalent single leads of colored
wire from thermostat subbase terminals to low-voltage connections on unit (shown in Fig. 11A and 11B) as described in Steps
1-4 below.
1. If unit is mounted on roof curb and accessory thru-thecurb service plate connection is used, route wire through
connection plate.
2. Pass control wires through the hole provided on unit
(see connection D in Connection Sizes table in Fig. 7A
and 7B).
3. Feed wires through the raceway built into the corner post
to the 24-v barrier located on the left side of the control
box. See Fig. 12. The raceway provides the UL-required
(Underwriters’ Laboratories) clearance between highand low-voltage wiring.
4. Connect thermostat wires to screw terminals on lowvoltage connection board.

NOTE: If a single power source is to be used, size wire to include power
exhaust MCA and MOCP.
Check MCA and MOCP when power exhaust is powered through the unit.
Determine the new MCA including the power exhaust using the following
formula:
MCA New = MCA unit only + MCA of Power Exhaust
For example, using a 48TF008 unit with MCA = 40.1 and MOCP = 45, with
CRPWREXH030A01 power exhaust.
MCA New = 40.1 amps + 1.6 amps = 41.7 amps
If the new MCA does not exceed the published MOCP, then MOCP would not
change. The MOCP in this example is 45 amps and the MCA New is below
45; therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the
MOCP for the power exhaust will be 15 amps per NEC.
Example: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v

NOTE: If a single power source is to be used, size wire to include power
exhaust MCA and MOCP.
Check MCA and MOCP when power exhaust is powered through the unit.
Determine the new MCA including the power exhaust using the following
formula:
MCA New = MCA unit only + MCA of Power Exhaust
For example, using a 48TF008 unit with MCA = 40.1 and MOCP = 45, with
CRPWREXH030A01 power exhaust.
MCA New = 40.1 amps + 1.6 amps = 41.7 amps
If the new MCA does not exceed the published MOCP, then MOCP would not
change. The MOCP in this example is 45 amps and the MCA New is below
45; therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the
MOCP for the power exhaust will be 15 amps per NEC.
Example: Supply voltage is 460-3-60.

NOTE: If a single power source is to be used, size wire to include power
exhaust MCA and MOCP.
Check MCA and MOCP when power exhaust is powered through the unit.
Determine the new MCA including the power exhaust using the following
formula:
MCA New = MCA unit only + MCA of Power Exhaust
For example, using a 48TF008 unit with MCA = 40.1 and MOCP = 45, with
CRPWREXH030A01 power exhaust.
MCA New = 40.1 amps + 1.6 amps = 41.7 amps
If the new MCA does not exceed the published MOCP, then MOCP would not
change. The MOCP in this example is 45 amps and the MCA New is below
45; therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the
MOCP for the power exhaust will be 15 amps per NEC.
Example: Supply voltage is 460-3-60.
AB = 452 v
BC = 464 v
AC = 455 v

PREMIERLINK™ CONTROL — The PremierLink controller is compatible with Carrier Comfort Network® (CCN)
devices. 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. Carrier’s diagnostic
standard tier display tools such as Navigator™ or Scrolling
Marquee can be used with the PremierLink controller.
The PremierLink controller (see Fig. 17A and 17B) requires
the use of a Carrier electronic thermostat or a CCN connection
for time broadcast to initiate its internal timeclock. This is
necessary for broadcast of time of day functions (occupied/
unoccupied). No sensors are supplied with the field-mounted
PremierLink control. The factory-installed PremierLink control includes only the supply-air sensor (SAT) and the outdoor
air temperature sensor (OAT) as standard. An indoor air quality
(CO2) sensor can be added as an option. Refer to Table 3 for
sensor usage. Refer to Fig. 18 for PremierLink controller
wiring. The PremierLink control may be mounted in the
control panel or an area below the control panel.
NOTE: PremierLink controller versions 1.3 and later are
shipped in Sensor mode. If used with a thermostat, the
PremierLink controller must be configured to Thermostat
mode.
Install the Supply Air Temperature Sensor (SAT) — When
the unit is supplied with a factory-mounted PremierLink control, the supply-air temperature (SAT) sensor (33ZCSENSAT)
is factory-supplied and wired. The wiring is routed from the
PremierLink control over the control box, through a grommet,
into the fan section, down along the back side of the fan, and
along the fan deck over to the supply-air opening.
The SAT probe is wire-tied to the supply-air opening (on the
horizontal opening end) in its shipping position. Remove the
sensor for installation. Re-position the sensor in the flange of
the supply-air opening or in the supply air duct (as required by
local codes). Drill or punch a 1/2-in. hole in the flange or duct.
Use two field-supplied, self-drilling screws to secure the sensor
probe in a horizontal orientation.
NOTE: The sensor must be mounted in the discharge airstream
downstream of the cooling coil and any heating devices. Be
sure the probe tip does not come in contact with any of the unit
or heat surfaces.
Outdoor Air Temperature Sensor (OAT) — When the unit is
supplied with a factory-mounted PremierLink control, the
outdoor-air temperature sensor (OAT) is factory-supplied and
wired.
Install the Indoor Air Quality (CO2) Sensor — Mount the
optional indoor air quality (CO2) sensor according to manufacturer specifications.
A separate field-supplied transformer must be used to power the CO2 sensor.
Wire the CO2 sensor to the COM and IAQI terminals of J5
on the PremierLink controller. Refer to the PremierLink Installation, Start-Up, and Configuration Instructions for detailed
wiring and configuration information.

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
(HH57AC078) is required for differential enthalpy control.
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.
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.
Outdoor Air Enthalpy Sensor/Enthalpy Controller
(HH57AC077) — To wire the outdoor air enthalpy sensor,
perform the following (see Fig. 19 and 20):
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. Connect 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 GRAY/ORN wire to J4-2 on PremierLink controller and to terminal (3) on enthalpy
sensor.
d. Connect the GRAY/RED wire to J4-1 on PremierLink controller and to terminal (2) on enthalpy sensor.
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.
Return Air Enthalpy Sensor — Mount the return-air enthalpy
sensor (HH57AC078) in the return-air duct. The return air
sensor is wired to the enthalpy controller (HH57AC077). The
outdoor enthalpy changeover set point is set at the controller.
To wire the return air enthalpy sensor, perform the following (see Fig. 19):
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.

Determine the EconoMi$er IV control mode before set up of
the control. Some modes of operation may require different sensors. Refer to Table 5. The EconoMi$er IV is supplied from the
factory with a supply air temperature sensor and an outdoor air
temperature sensor. This allows for operation of the
EconoMi$er IV with outdoor air dry bulb changeover control.
Additional accessories can be added to allow for different types
of changeover control and operation of the EconoMi$er IV and
unit.
Supply Air Temperature (SAT) Sensor — The supply air
temperature sensor is a 3 K thermistor located at the inlet of the
indoor fan. See Fig. 33. This sensor is factory installed. The operating range of temperature measurement is 0° to 158 F. See
Table 4 for sensor temperature/resistance values.
The temperature sensor looks like an eyelet terminal with
wires running to it. The sensor is located in the “crimp end”
and is sealed from moisture.

Outdoor Dry Bulb Changeover — The standard controller is
shipped from the factory configured for outdoor dry bulb
changeover control. The outdoor air and supply air temperature
sensors are included as standard. For this control mode, the
outdoor temperature is compared to an adjustable set point
selected on the control. If the outdoor-air temperature is above
the set point, the EconoMi$er IV will adjust the outdoor air
dampers to minimum position. If the outdoor-air temperature is
below the set point, the position of the outdoor air dampers will
be controlled to provide free cooling using outdoor air. When
in this mode, the LED next to the free cooling set point potentiometer will be on. The changeover temperature set point is
controlled by the free cooling set point potentiometer located
on the control. See Fig. 34. The scale on the potentiometer is A,
B, C, and D. See Fig. 35 for the corresponding temperature
changeover values.
Differential Dry Bulb Control — For differential dry bulb
control the standard outdoor dry bulb sensor is used in conjunction with an additional accessory dry bulb sensor (part number
CRTEMPSN002A00). The accessory sensor must be mounted
in the return airstream. See Fig. 36. Wiring is provided in the
EconoMi$er IV wiring harness. See Fig. 28.
In this mode of operation, the outdoor air temperature is
compared to the return air temperature and the lower temperature air stream is used for cooling. When using this mode of
changeover control, turn the enthalpy setpoint potentiometer
fully clockwise to the D setting. See Fig. 34.

ECONOMI$ER IV CONTROL MODES
IMPORTANT: The optional EconoMi$er2 does not
include a controller. The EconoMi$er2 is operated by a 4 to
20 mA signal from an existing field-supplied controller
(such as PremierLink™ control). See Fig. 29 for wiring
information.

Outdoor Enthalpy Changeover — For enthalpy control, accessory enthalpy sensor (part number HH57AC074) is required. Replace the standard outdoor dry bulb temperature sensor with the accessory enthalpy sensor in the same mounting
location. See Fig. 21. When the outdoor air enthalpy rises
above the outdoor enthalpy changeover set point, the outdoorair damper moves to its minimum position. The outdoor
enthalpy changeover set point is set with the outdoor enthalpy
set point potentiometer on the EconoMi$er IV controller. The
set points are A, B, C, and D. See Fig. 37. The factory-installed
620-ohm jumper must be in place across terminals SR and SR+
on the EconoMi$er IV controller. See Fig. 21 and 38.
Differential Enthalpy Control — For differential enthalpy
control, the EconoMi$er IV controller uses two enthalpy sensors (HH57AC078 and CRENTDIF004A00), one in the outside air and one in the return air duct. The EconoMi$er IV
controller compares the outdoor air enthalpy to the return air
enthalpy to determine EconoMi$er IV use. The controller
selects the lower enthalpy air (return or outdoor) for cooling.
For example, when the outdoor air has a lower enthalpy than
the return air, the EconoMi$er IV opens to bring in outdoor air
for free cooling.
Replace the standard outside air dry bulb temperature sensor with the accessory enthalpy sensor in the same mounting
location. See Fig. 21. Mount the return air enthalpy sensor in
the return air duct. See Fig. 36. Wiring is provided in the
EconoMi$er IV wiring harness. See Fig. 28. The outdoor enthalpy changeover set point is set with the outdoor enthalpy set
point potentiometer on the EconoMi$er IV controller. When
using this mode of changeover control, turn the enthalpy setpoint potentiometer fully clockwise to the D setting.
Indoor Air Quality (IAQ) Sensor Input — The IAQ input
can be used for demand control ventilation control based on the
level of CO2 measured in the space or return air duct.
Mount the accessory IAQ sensor according to manufacturer
specifications. The IAQ sensor should be wired to the AQ and
AQ1 terminals of the controller. Adjust the DCV potentiometers to correspond to the DCV voltage output of the indoor air
quality sensor at the user-determined set point. See Fig. 39.
If a separate field-supplied transformer is used to power the
IAQ sensor, the sensor must not be grounded or the
EconoMi$er IV control board will be damaged.

DAMPER VOLTAGE FOR MAX VENTILATION RATE
Fig. 39 — CO2 Sensor Maximum Range Setting
Fig. 38 — EconoMi$er IV Control
28
Damper Movement — Damper movement from full open to
full closed (or vice versa) takes 21/2 minutes.
Thermostats — The EconoMi$er IV control works with conventional thermostats that have a Y1 (cool stage 1), Y2 (cool
stage 2), W1 (heat stage 1), W2 (heat stage 2), and G (fan). The
EconoMi$er IV control does not support space temperature
sensors. Connections are made at the thermostat terminal connection board located in the main control box.
Occupancy Control — The factory default configuration for
the EconoMi$er IV control is occupied mode. Occupied status
is provided by the black jumper from terminal TR to terminal
N. When unoccupied mode is desired, install a field-supplied
timeclock function in place of the jumper between TR and N.
See Fig. 28. When the timeclock contacts are closed, the
EconoMi$er IV control will be in occupied mode. When the
timeclock contacts are open (removing the 24-v signal from
terminal N), the EconoMi$er IV will be in unoccupied mode.
Demand Controlled Ventilation (DCV) — When using the
EconoMi$er IV for demand controlled ventilation, there are
some equipment selection criteria which should be considered.
When selecting the heat capacity and cool capacity of the
equipment, the maximum ventilation rate must be evaluated for
design conditions. The maximum damper position must be calculated to provide the desired fresh air.
Typically the maximum ventilation rate will be about 5 to
10% more than the typical cfm required per person, using normal outside air design criteria.
A proportional anticipatory strategy should be taken with
the following conditions: a zone with a large area, varied occupancy, and equipment that cannot exceed the required ventilation rate at design conditions. Exceeding the required ventilation rate means the equipment can condition air at a maximum
ventilation rate that is greater than the required ventilation rate
for maximum occupancy. A proportional-anticipatory strategy
will cause the fresh air supplied to increase as the room CO2
level increases even though the CO2 set point has not been
reached. By the time the CO2 level reaches the set point, the
damper will be at maximum ventilation and should maintain
the set point.
In order to have the CO2 sensor control the economizer
damper in this manner, first determine the damper voltage output for minimum or base ventilation. Base ventilation is the
ventilation required to remove contaminants during unoccupied periods. The following equation may be used to determine
the percent of outside-air entering the building for a given
damper position. For best results there should be at least a
10 degree difference in outside and return-air temperatures.
OA
RA
(TO x
) + (TR x
) = TM
100
100
TO = Outdoor-Air Temperature
OA = Percent of Outdoor Air
TR = Return-Air Temperature
RA = Percent of Return Air
TM = Mixed-Air Temperature
Once base ventilation has been determined, set the minimum damper position potentiometer to the correct position.
The same equation can be used to determine the occupied or
maximum ventilation rate to the building. For example, an output of 3.6 volts to the actuator provides a base ventilation rate
of 5% and an output of 6.7 volts provides the maximum ventilation rate of 20% (or base plus 15 cfm per person). Use Fig. 39
to determine the maximum setting of the CO2 sensor. For example, a 1100 ppm set point relates to a 15 cfm per person design. Use the 1100 ppm curve on Fig. 39 to find the point when
the CO2 sensor output will be 6.7 volts. Line up the point on the
graph with the left side of the chart to determine that the range
configuration for the CO2 sensor should be 1800 ppm. The
EconoMi$er IV controller will output the 6.7 volts from the
CO2 sensor to the actuator when the CO2 concentration in the
Exhaust Set Point Adjustment — The exhaust set point will
determine when the exhaust fan runs based on damper position
(if accessory power exhaust is installed). The set point is modified with the Exhaust Fan Set Point (EXH SET) potentiometer.
See Fig. 34. The set point represents the damper position above
which the exhaust fans will be turned on. When there is a call
for exhaust, the EconoMi$er IV controller provides a
45 ± 15 second delay before exhaust fan activation to allow the
dampers to open. This delay allows the damper to reach the
appropriate position to avoid unnecessary fan overload.
Minimum Position Control — There is a minimum damper
position potentiometer on the EconoMi$er IV controller. See
Fig. 34. The minimum damper position maintains the minimum airflow into the building during the occupied period.
When using demand ventilation, the minimum damper position represents the minimum ventilation position for VOC
(volatile organic compound) ventilation requirements. The
maximum demand ventilation position is used for fully occupied ventilation.
When demand ventilation control is not being used, the
minimum position potentiometer should be used to set the occupied ventilation position. The maximum demand ventilation
position should be turned fully clockwise.
Adjust the minimum position potentiometer to allow the
minimum amount of outdoor air, as required by local codes, to
enter the building. Make minimum position adjustments with
at least 10 F temperature difference between the outdoor and
return-air temperatures.
To determine the minimum position setting, perform the
following procedure:
1. Calculate the appropriate mixed air temperature using the
following formula:
OA
RA
) + (TR x
) = TM
(TO x
100
100
TO = Outdoor-Air Temperature
OA = Percent of Outdoor Air
TR = Return-Air Temperature
RA = Percent of Return Air
TM = Mixed-Air Temperature
As an example, if local codes require 10% outdoor air
during occupied conditions, outdoor-air temperature is
60 F, and return-air temperature is 75 F.
(60 x .10) + (75 x .90) = 73.5 F
2. Disconnect the supply air sensor from terminals T and
T1.
3. Ensure that the factory-installed jumper is in place across
terminals P and P1. If remote damper positioning is being
used, make sure that the terminals are wired according to
Fig. 28 and that the minimum position potentiometer is
turned fully clockwise.
4. Connect 24 vac across terminals TR and TR1.
5. Carefully adjust the minimum position potentiometer
until the measured supply air temperature matches the
calculated value.
6. Reconnect the supply air sensor to terminals T and T1.
Remote control of the EconoMi$er IV damper is desirable
when requiring additional temporary ventilation. If a
field-supplied remote potentiometer (Honeywell part number
S963B1128) is wired to the EconoMi$er IV controller, the
minimum position of the damper can be controlled from a remote location.
To control the minimum damper position remotely, remove
the factory-installed jumper on the P and P1 terminals on the
EconoMi$er IV controller. Wire the field-supplied potentiometer to the P and P1 terminals on the EconoMi$er IV controller.
See Fig. 38.
29
Step 9 — Adjust Evaporator-Fan Speed — Ad-
space is at 1100 ppm. The DCV set point may be left at 2 volts
since the CO2 sensor voltage will be ignored by the
EconoMi$er IV controller until it rises above the 3.6 volt setting of the minimum position potentiometer.
Once the fully occupied damper position has been determined, set the maximum damper demand control ventilation
potentiometer to this position. Do not set to the maximum position as this can result in over-ventilation to the space and potential high-humidity levels.
CO 2 Sensor Configuration — The CO2 sensor has preset
standard voltage settings that can be selected anytime after the
sensor is powered up. See Table 6.
Use setting 1 or 2 for Carrier equipment. See Table 6.
1. Press Clear and Mode buttons. Hold at least 5 seconds
until the sensor enters the Edit mode.
2. Press Mode twice. The STDSET Menu will appear.
3. Use the Up/Down button to select the preset number. See
Table 6.
4. Press Enter to lock in the selection.
5. Press Mode to exit and resume normal operation.
The custom settings of the CO2 sensor can be changed anytime after the sensor is energized. Follow the steps below to
change the non-standard settings:
1. Press Clear and Mode buttons. Hold at least 5 seconds
until the sensor enters the Edit mode.
2. Press Mode twice. The STDSET Menu will appear.
3. Use the Up/Down button to toggle to the NONSTD menu
and press Enter.
4. Use the Up/Down button to toggle through each of the
nine variables, starting with Altitude, until the desired setting is reached.
5. Press Mode to move through the variables.
6. Press Enter to lock in the selection, then press Mode to
continue to the next variable.
Dehumidification of Fresh Air with DCV Control — Information from ASHRAE indicates that the largest humidity load
on any zone is the fresh air introduced. For some applications,
a device such as a 62AQ energy recovery unit is added to reduce the moisture content of the fresh air being brought into the
building when the enthalpy is high. In most cases, the normal
heating and cooling processes are more than adequate to remove the humidity loads for most commercial applications.
If normal rooftop heating and cooling operation is not adequate for the outdoor humidity level, an energy recovery unit
and/or a dehumidification option should be considered.

NOTE: All indoor-fan motors 5 hp and larger meet the minimum efficiency requirements as established by the Energy Policy Act of 1992
(EPACT) effective October 24, 1997.
*Extensive motor and electrical testing on these units ensures that
the full horsepower range of the motors can be utilized with confidence. Using the fan motors up to the horsepower ratings shown in
this table will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected.

*The static pressure must be added to external static pressure. The sum and
the evaporator entering-air cfm should be used in conjunction with the Fan
Performance tables to determine indoor blower rpm and watts.
GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES
1. Fan Performance is based on clean filters and wet coil data.
2. Extensive motor and electrical testing on these units ensures
that the full range of the motor can be utilized with confidence.
Using the fan motors up to the wattage ratings shown will not
result in nuisance tripping or premature motor failure. Unit
warranty will not be affected. See Evaporator-Fan Motor Performance data, Table 9, for additional information.
3. Use of a field-supplied motor may affect wire sizing. Contact
your Carrier representative for details.
4. Interpolation is permissible. Do not extrapolate.

PRE-START-UP
Return-Air Filters — Make sure correct filters are installed in filter tracks (see Tables 1A and 1B). Do not operate
unit without return-air filters.
Failure to observe the following warnings could result in
serious personal injury.
1. Follow recognized safety practices and wear protective
goggles when checking or the servicing refrigerant
system.
2. Do not operate the compressor or provide any electric
power to the unit unless the compressor terminal cover
is in place and secured.
3. Do not remove the compressor terminal cover until all
electrical sources are disconnected.
4. Relieve all pressure from the system before touching or
disturbing anything inside the compressor terminal box
if refrigerant leak is suspected around the compressor
terminals.
5. Never attempt to repair a soldered connection while the
refrigerant system is under pressure.
6. Do not use torch to remove any component. The system contains oil and refrigerant under pressure. To
remove a component, wear protective goggles and proceed as follows:
a. Shut off gas and then electrical power to the unit.
Install lockout tag.
b. Relieve all pressure from the system using both
high-pressure and low-pressure ports.
c. Cut the component connection tubing with a tubing
cutter, and remove the component from the unit.
d. Carefully unsweat the remaining tubing stubs when
necessary. Oil can ignite when exposed to torch
flame.
Outdoor-Air Inlet Screens — Outdoor-air inlet screens
must be in place before operating unit.
Compressor Mounting — Compressors are internally
spring mounted. Do not loosen or remove compressor holddown bolts. On 48TF,TM014 units, remove the tiedown bands
that hold the compressors together.
Internal Wiring — Check all electrical connections in
unit control boxes. Tighten as required. Ensure wiring does not
come into direct contact with refrigerant tubing.
Gas Piping — Check gas piping for leaks.
Disconnect gas piping from unit when leak
testing at pressure greater than 1/2 psig. Pressures greater than 1/2 psig will cause gas
valve damage resulting in hazardous condition. If gas valve is subjected to pressure
greater than 1/2 psig, it must be replaced
before use. When pressure testing fieldsupplied gas piping at pressures of 1/2 psig
or less, a unit connected to such piping must
be isolated by manually closing the gas
valve.
Refrigerant Service Ports — To service refrigerant
service ports, remove compressor access panel. Each unit system has 3 Schrader-type service gage ports: one on the suction
line, one on the liquid line, and one on the compressor discharge line. Be sure that caps on the ports are tight. The
Schrader-type valve on the discharge line is located under the
low-pressure switch. Another valve is located on the discharge
line underneath the high-pressure switch. It is screwed on a
Schrader fitting but there is no Schrader core.
Proceed as follows to inspect and prepare the unit for initial
start-up:
1. Remove all access panels.
2. Read and follow instructions on all WARNING, CAUTION, and INFORMATION labels attached to, or
shipped with, the unit.
3. Make the following inspections:
a. Inspect for shipping and handling damages such as
broken lines, loose parts, or disconnected wires, etc.
b. Inspect for oil at all refrigerant tubing connections
and on unit base. Detecting oil generally indicates a
refrigerant leak. Leak-test all refrigerant tubing connections using an electronic leak detector, halide
torch, or liquid-soap solution.
c. Inspect all field-wiring and factory-wiring connections. Be sure that connections are completed and tight.
d. Inspect coil fins. If damaged during shipping and handling, carefully straighten the fins with a fin comb.
4. Verify the following conditions:
a. Make sure that condenser fan blade is correctly positioned in the fan orifice. See Condenser-Fan Adjustment section on page 68 for more details.
b. Make sure that air filter(s) is in place.
c. Make sure that condensate drain trap is filled with
water to ensure proper drainage.
d. Make sure that all tools and miscellaneous loose parts
have been removed.
High Flow Valves — Located on the compressor hot gas
and suction tubes are High Flow Valves. Large black plastic
caps distinguish these valves with O-rings located inside the
caps. These valves can not be accessed for service in the field.
Ensure the plastic caps are in place and tight or the possibility
of refrigerant leakage could occur.
Compressor Rotation — On 3-phase units with scroll
compressors, it is important to be certain compressor is rotating
in the proper direction. To determine whether or not compressor is rotating in the proper direction:
1. Connect service gages to suction and discharge pressure
fittings.
2. Energize the compressor.
3. The suction pressure should drop and the discharge pressure should rise, as is normal on any start-up.
If the suction pressure does not drop and the discharge pressure does not rise to normal levels:
1. Note that the evaporator fan is probably also rotating in
the wrong direction.
2. Turn off power to the unit and install lockout tag.
3. Reverse any two of the unit power leads.
4. Reapply power to unit. Reenergize compressor.
The suction and discharge pressure levels should now move
to their normal start-up levels.
NOTE: When the compressor is rotating in the wrong direction, the unit will make an elevated level of noise and will not
provide cooling.
START-UP
Unit Preparation — Make sure that unit has been installed in accordance with these installation instructions and
applicable codes. Make sure that Start-Up Checklist, located on
back page of this booklet, has been completed and filled out.
63
Cooling — To start unit, turn on main power supply. Set
system selector switch at COOL position and fan switch at
AUTO. position. Adjust thermostat to a setting below room
temperature. Compressor, indoor and outdoor fans start on closure of contactors.
Check unit charge. Refer to Checking and Adjusting Refrigerant Charge section, page 68. Unit must operate a minimum of
10 minutes before adjusting charge.
Reset thermostat at a position above room temperature.
Compressor and outdoor fans will shut off. Evaporator fan will
shut off after 30-second delay.
TO SHUT OFF UNIT — Set system selector switch at OFF
position. Resetting thermostat at a position above room temperature shuts unit off temporarily until space temperature exceeds thermostat setting.
Heating
1. Purge gas supply line of air by opening union ahead of
gas valve. When gas odor is detected, tighten union and
wait 5 minutes before proceeding.
2. Turn on electrical supply and open manual gas valve.
3. Set system switch selector at HEAT position and fan
switch at AUTO. or ON position. Set heating temperature
lever above room temperature.
4. The induced-draft motor will start, purging heat
exchangers.
5. After a call for heating, the main burners should light
within 5 seconds. If the burners do not light, then there is
a 22-second delay before another 5-second ignition try.
If the burners still do not light, the time delay is repeated.
If the burners do not light within 15 minutes, there is a
lockout. To reset the control, break the 24 v power to W1.
6. The evaporator-fan motor will turn on 45 seconds after
the burners are ignited.
7. The evaporator-fan motor will turn off 45 seconds after
the thermostat temperature is satisfied.
8. Adjust airflow to obtain a temperature rise within the
range specified on the unit nameplate and in Tables 1A
and 1B.
Main Burners — Main burners are factory set and should
require no adjustment.
TO CHECK ignition of main burners and heating controls,
move thermostat set point above room temperature and verify
that the burners light and evaporator fan is energized. After ensuring that the unit continues to heat the building, lower the
thermostat setting below the room temperature and verify that
the burners and evaporator fan turn off (fan will turn off only if
fan selector switch is in the AUTO. position). Refer to Table 42
for the correct orifice to use at high altitudes.
NOTE: Upon a call for heat, the main burners will remain on
for a minimum of 60 seconds.
ADJUST GAS INPUT — The gas input to the unit is determined by measuring the gas flow at the meter or by measuring
the manifold pressure. Manifold pressure should be 3.5 in. wg.
NOTE: On units that use a 2-stage gas valve there is no need to
adjust the “Low Fire” manifold pressure.
Measure Gas Flow (Natural Gas Units) — Minor adjustment
to the gas flow can be made by changing the manifold pressure.
The manifold pressure must be 3.5 in wg. Normal manifold
pressure is 3.5 in. wg in high fire (W1 and W2 inputs to gas
valve).
Proceed as follows:
1. Turn off gas supply to unit.
2. Remove pipe plug on manifold then connect manometer
at this point. Turn on gas to unit. Ensure gas valve is in
high fire operation.
Observe manifold pressure and proceed as follows to adjust
gas input:
1. Remove cover screw over regulator adjustment screw on
gas valve. Ensure gas valve is operating in high fire
mode.
2. Turn regulator adjustment screw clockwise to increase
gas input, or turn regulator adjustment screw counterclockwise to decrease input. High fire manifold pressure
must be 3.5 in. wg.

*As the height above sea level increases, there is less oxygen per cubic
foot of air. Therefore, heat input rate should be reduced at higher
altitudes.

Integrated Gas Controller (IGC) Operation
NOTE: The default value for the evaporator-fan motor ON and
OFF delay is 45 seconds. The Integrated Gas Controller (IGC)
modifies this value when abnormal limit switch cycles occur.
Based upon unit operating conditions, the ON delay can be
reduced to 0 seconds and the OFF delay can be extended to
180 seconds.
When one flash of the LED (light-emitting diode) is observed, the evaporator-fan ON/OFF delay has been modified.
If the limit switch trips at the start of the heating cycle during
the evaporator ON delay, the time period of the ON delay for
the next cycle will be 5 seconds less than the time at which the
switch tripped. (Example: If the limit switch trips at 30 seconds, the evaporator-fan ON delay for the next cycle will occur
at 25 seconds.) To prevent short-cycling, a 5-second reduction
will only occur if a minimum of 10 minutes has elapsed since
the last call for heating.
Unsafe operation of the unit may result if manifold pressure is outside 3.4 to 3.6 in. wg range. Personal injury or
unit damage may result.
3. Replace cover screw cap on gas valve.
4. Turn off gas supply to unit. Remove manometer from
pressure tap and replace pipe plug on gas valve. Turn on
gas to unit and check for leaks.
64
at the minimum open position. Below 45 F the dampers will
be completely shut. As the supply-air temperature rises, the
dampers will come back open to the minimum open position
once the supply-air temperature rises to 48 F.
If optional power exhaust is installed, as the outdoor-air
damper opens and closes, the power exhaust fans will be energized and deenergized.
If field-installed accessory CO2 sensors are connected to the
EconoMi$er IV control, a demand controlled ventilation strategy will begin to operate. As the CO2 level in the zone increases
above the CO2 set point, the minimum position of the damper
will be increased proportionally. As the CO2 level decreases
because of the increase in fresh air, the outdoor-air damper will
be proportionally closed. Damper position will follow the higher demand condition from DCV mode or free cooling mode.
Damper movement from full closed to full open (or vice
versa) will take between 11/2 and 21/2 minutes.
If free cooling can be used as determined from the appropriate changeover command (switch, dry bulb, enthalpy curve,
differential dry bulb, or differential enthalpy), a call for cooling
(Y1 closes at the thermostat) will cause the control to modulate
the dampers open to maintain the supply air temperature set
point at 50 to 55 F.
As the supply air temperature drops below the set point
range of 50 to 55 F, the control will modulate the outdoor-air
dampers closed to maintain the proper supply-air temperature.
HEATING, UNITS WITH ECONOMI$ER IV — When the
room temperature calls for heat, the heating controls are energized as described in the Heating, Units Without Economizer
section. When the thermostat is satisfied, the economizer
damper moves to the minimum position.
COOLING, UNITS WITH ECONOMI$ER2, PREMIERLINK™ CONTROL AND A THERMOSTAT — When free
cooling is not available, the compressors will be controlled by
the PremierLink control in response to the Y1 and Y2 inputs
from the thermostat.
The PremierLink control will use the following information
to determine if free cooling is available:
• Indoor fan has been on for at least 30 seconds.
• The SPT, SAT, and OAT inputs must have valid readings.
• OAT must be less than 75 F.
• OAT must be less than SPT.
• Enthalpy must be LOW (may be jumpered if an enthalpy
sensor not available).
• Economizer position is NOT forced.
Pre-cooling occurs when the is no call from the thermostat
except G. Pre-cooling is defined as the economizer modulates
to provide 70 F supply air.
When free cooling is available the PremierLink control will
control the compressors and economizer to provide a supplyair temperature determined to meet the Y1 and Y2 calls from
the thermostat using the following three routines. The three
control routines are based on OAT.
The 3 routines are based on OAT where:
SASP = Supply Air Set Point
DXCTLO = Direct Expansion Cooling Lockout Set Point
PID = Proportional Integral
Routine 1 (OAT < DXCTLO)
• Y1 energized – economizer maintains a SASP =
(SATLO1 + 3).
• Y2 energized – economizer maintains a SASP =
(SATLO2 + 3).
The evaporator-fan OFF delay can also be modified. Once
the call for heating has ended, there is a 10-minute period during which the modification can occur. If the limit switch trips
during this period, the evaporator-fan OFF delay will increase
by 15 seconds on the next cycle. A maximum of 9 trips can
occur, extending the evaporator-fan OFF delay to 180 seconds.
To restore the original default value, reset the power to the unit.
TO SHUT OFF UNIT — Set system selector switch at OFF
position. Resetting heating selector lever below room temperature will shut unit off temporarily until space temperature falls
below thermostat setting.
Safety Relief — A soft-solder joint at the suction line
Schrader port provides pressure relief under abnormal temperature and pressure conditions.
Ventilation (Continuous Fan) — Set fan and system
selector switches at ON and OFF positions, respectively.
Evaporator fan operates continuously to provide constant air
circulation. When the evaporator-fan selector switch is turned
to the OFF position, there is a 30-second delay before the fan
turns off.
Operating Sequence
COOLING, UNITS WITHOUT ECONOMIZER — When
thermostat calls for cooling, terminals G and Y1 are energized.
The indoor (evaporator) fan contactor (IFC), compressor contactor no. 1 (C1) and outdoor-fan contactor (OFC) are energized, and evaporator-fan motor, compressor no. 1, and both
condenser fans start. The condenser-fan motors run continuously while unit is cooling. If the thermostat calls for a second stage
of cooling by energizing Y2, compressor contactor no. 2 (C2) is
energized and compressor no. 2 starts.
When the thermostat is satisfied, C1 and C2 are deenergized and the compressors and outdoor (condenser) fan motors
(OFM) shut off. After a 30-second delay, the indoor (evaporator) fan motor (IFM) shuts off. If the thermostat fan selector
switch is in the ON position, the evaporator-fan motor will run
continuously.
HEATING, UNITS WITHOUT ECONOMIZER — When
the thermostat calls for heating, terminal W1 is energized. In
order to prevent thermostat short-cycling, the unit is locked
into the Heating mode for at least 1 minute when W1 is energized. The induced-draft motor (IDM) is then energized and
the burner ignition sequence begins. The indoor (evaporator)
fan motor (IFM) is energized 45 seconds after a flame is
ignited. On units equipped for two stages of heat, when additional heat is needed, W2 is energized and the high-fire solenoid on the main gas valve (MGV) is energized. When the
thermostat is satisfied and W1 and W2 are deenergized, the
IFM stops after a 45-second time-off delay.
COOLING, UNITS WITH ECONOMI$ER IV — When free
cooling is not available, the compressors will be controlled by
the zone thermostat. When free cooling is available, the
outdoor-air damper is modulated by the EconoMi$er IV control to provide a 50 to 55 F supply-air temperature into the
zone. As the supply-air temperature fluctuates above 55 or
below 50 F, the dampers will be modulated (open or close)
to bring the supply-air temperature back within the set point
limits.
For EconoMi$er IV operation, there must be a thermostat
call for the fan (G). This will move the damper to its minimum
position during the occupied mode.
Above 50 F supply-air temperature, the dampers will modulate from 100% open to the minimum open position. From 50 F
to 45 F supply-air temperature, the dampers will maintain
65
into the zone. The supply air will maintain the space temperature between the heating and cooling set points as indicated in
Fig. 44.
The PremierLink will integrate the compressors stages with
the economizer based on similar logic as the three routines listed in the previous section. The SASP will float up and down
based on the error reduction calculations that compare space
temperature and space set point.
When outdoor-air temperature conditions require the economizer to close for a compressor stage-up sequence, the economizer control integrator is reset to zero after the stage-up sequence is completed. This prevents the supply-air temperature
from dropping too quickly and creating a freeze condition that
would make the compressor turn off prematurely.
The high space set point is used for DX (direct expansion)
cooling control, while the economizer space set point is a
calculated value between the heating and cooling set points.
The economizer set point will always be at least one degree
below the cooling set point, allowing for a smooth transition
from mechanical cooling with economizer assist, back to
economizer cooling as the cooling set point is achieved.
The compressors may be used for initial cooling then the
PremierLink controller will modulate the economizer using an
error reduction calculation to hold the space temperature
between the heating and cooling set points. See Fig. 44.
The controller uses the following conditions to determine
economizer cooling:
• Enthalpy is Low
• SAT reading is available
• OAT reading is available
• SPT reading is available
• OAT ≤ SPT
• Economizer Position is NOT forced
Routine 2 (DXCTLO < OAT < 68 F)
• If only Y1 energized, the economizer maintains a SASP
= (SATLO1 + 3).
• If SAT > SASP + 5 and economizer position > 80%,
economizer will go to minimum position for 3 minutes or
until SAT > 68 F.
• First stage of mechanical cooling will be energized.
• Integrator resets.
• Economizer opens again and controls to current SASP
after stage one on for 90 seconds.
• With Y1 and Y2 energized economizer maintains an
SASP = SATLO2 + 3.
• If SAT > SASP + 5 and economizer position >80%,
economizer will go to minimum position for 3 minutes or
until SAT > 68 F.
• If compressor one is on then second stage of mechanical
cooling will be energized. Otherwise the first stage will
be energized.
• Integrator resets.
• Economizer opens again and controls to SASP after
stage one on for 90 seconds.
Routine 3 (OAT > 68)
• Economizer is opened 100%.
• Compressors 1 and 2 are cycled based on Y1 and Y2
using minimum on and off times and watching the supply air temperature as compared to SATLO1 and
SATLO2 set points.
If optional power exhaust is installed, as the outdoor-air
damper opens and closes, the power exhaust fans will be energized and deenergized.
If field-installed accessory CO2 sensors are connected to the
PremierLink™ control, a PID-controlled demand ventilation
strategy will begin to operate. As the CO2 level in the zone
increases above the CO2 set point, the minimum position of the
damper will be increased proportionally. As the CO2 level
decreases because of the increase in fresh air, the outdoor-air
damper will be proportionally closed.
HEATING, UNITS WITH ECONOMI$ER2, PREMIERLINK
CONTROL AND A THERMOSTAT — When the thermostat
calls for heating, terminal W1 is energized. The PremierLink
control will move the economizer damper to the minimum
position if there is a call for G and closed if there is a call for
W1 without G. In order to prevent thermostat from short cycling, the unit is locked into the heating mode for at least
10 minutes when W1 is energized. The induced-draft motor is
then energized and the burner ignition sequence begins.
On units equipped for two stages of heat, when additional
heat is needed, W2 is energized and the high-fire solenoid on
the main gas valve (MGV) is energized. When the thermostat
is satisfied and W1 is deenergized, the IFM stops after a
45-second time-off delay unless G is still maintained.
COOLING, UNITS WITH ECONOMI$ER2, PREMIERLINK CONTROL AND A ROOM SENSOR — When free
cooling is not available, the compressors will be controlled by
the PremierLink controller using a PID Error reduction calculation as indicated by Fig 43.
The PremierLink controller will use the following information to determine if free cooling is available:
• Indoor fan has been on for at least 30 seconds.
• The SPT, SAT, and OAT inputs must have valid readings.
• OAT must be less than 75 F.
• OAT must be less than SPT.
• Enthalpy must be LOW (may be jumpered if and
enthalpy sensor is not available).
• Economizer position is NOT forced.
When free cooling is available, the outdoor-air damper is
positioned through the use of a Proportional Integral (PID)
control process to provide a calculated supply-air temperature

If any of the above conditions are not met, the economizer
submaster reference (ECSR) is set to maximum limit and the
damper moves to minimum position. The operating sequence
is complete. The ECSR is recalculated every 30 seconds.
If an optional power exhaust is installed, as the outdoor-air
damper opens and closes, the power exhaust fans will be
energized and deenergized.
If field-installed accessory CO2 sensors are connected to
the PremierLink™ control, a PID-controlled demand ventilation strategy will begin to operate. As the CO2 level in the zone
increases above the CO2 set point, the minimum position of the
damper will be increased proportionally. As the CO2 level
decreases because of the increase in fresh air, the outdoor-air
damper will be proportionally closed.
HEATING, UNIT WITH ECONOMI$ER2, PREMIERLINK
CONTROL AND A ROOM SENSOR — Every 40 seconds
the controller will calculate the required heat stages (maximum
of 3) to maintain supply air temperature (SAT) if the following
qualifying conditions are met:
• Indoor fan has been on for at least 30 seconds.
• COOL mode is not active.
• OCCUPIED, TEMP.COMPENSATED START or HEAT
mode is active.
• SAT reading is available.
• Fire shutdown mode is not active.
If all of the above conditions are met, the number of heat
stages is calculated; otherwise the required number of heat
stages will be set to 0.
If the PremierLink controller determines that heat stages are
required, the economizer damper will be moved to minimum
position if occupied and closed if unoccupied.
Staging should be as follows:
If Heating PID STAGES=2
• HEAT STAGES=1 (50% capacity) will energize HS1
• HEAT STAGES=2 (100% capacity) will energize HS2
If Heating PID STAGES=3 and AUXOUT = HS3
• HEAT STAGES=1 (33% capacity) will energize HS1
• HEAT STAGES=2 (66% capacity) will energize HS2
• HEAT STAGES=3 (100% capacity) will energize HS3
In order to prevent short cycling, the unit is locked into the
Heating mode for at least 10 minutes when HS1 is deenergized.
When HS1 is energized the induced-draft motor is then
energized and the burner ignition sequence begins. On units
equipped for two stages of heat, when additional heat is needed, HS2 is energized and the high-fire solenoid on the main gas
valve (MGV) is energized. When the space condition is satisfied and HS1 is deenergized the IFM stops after a 45-second
time-off delay unless in the occupied mode. The fan will run
continuously in the occupied mode as required by national
energy and fresh air standards.
2. If economizer is installed, remove economizer by disconnecting Molex plug and removing economizer mounting
screws. Refer to Accessory Economizer Installation Instructions for more details.
3. Remove filters from unit.
4. Clean coil using a commercial coil cleaner or dishwasher
detergent in a pressurized spray canister. Wash both sides
of coil and flush with clean water. For best results, backflush toward return-air section to remove foreign material. Caution should be taken as to not overflow the evaporator drain condensate pan.
5. Flush condensate pan after completion.
6. Reinstall economizer and filters.
7. Reconnect wiring.
8. Replace access panels.

hot gas line is a high-pressure switch. This switch opens at
428 psig and closes at 320 psig. No adjustment is necessary.
Refer to Tables 1A and 1B.
Loss-of-Charge Switch — Located on the condenser
liquid line is a low-pressure switch which functions as a lossof-charge switch. This switch contains a Schrader core depressor. This switch opens at 7 psig and closes at 22 psig. No adjustment is necessary. Refer to Tables 1A and 1B.
Freezestat — Located on the “hair pin” end of the evaporator coil is a bimetal temperature sensing switch. This switch
protects the evaporator coil from freeze-up due to lack of airflow. The switch opens at 30 F and closes at 45 F. No adjustment is necessary. Refer to Tables 1A and 1B.
Checking and Adjusting Refrigerant Charge —
The refrigerant system is fully charged with R-22 refrigerant,
tested, and factory-sealed. Unit must operate in Cooling mode
a minimum of 10 minutes before checking charge.
NOTE: Adjustment of the refrigerant charge is not required
unless the unit is suspected of not having the proper R-22 charge.
A superheat charging chart is attached to the outside of the
service access panel. The chart includes the required suction
line temperature at given suction line pressures and outdoor
ambient temperatures.
An accurate superheat, thermocouple-type or thermistortype thermometer, and a gage manifold are required when
using the superheat charging method for evaluating the unit
charge. Do not use mercury or small dial-type thermometers
because they are not adequate for this type of measurement.
Fig. 47 — Separating Coil Sections
Lubrication
COMPRESSORS — Each compressor is charged with the
correct amount of oil at the factory.
FAN-MOTOR BEARINGS — Fan-motor bearings are of
the permanently lubricated type. No further lubrication is
required. No lubrication of condenser-fan or evaporator-fan
motors is required.
When evaluating the refrigerant charge, an indicated
adjustment to the specified factory charge must always be
very minimal. If a substantial adjustment is indicated, an
abnormal condition exists somewhere in the cooling system, such as insufficient airflow across either coil or both
coils.
Condenser-Fan Adjustment (Fig. 48)
1. Shut off unit power supply and tag disconnect.
2. Remove condenser-fan assembly (grille, motor, motor
cover, and fan) and loosen fan hub setscrews.
3. Adjust fan height as shown in Fig. 48.
4. Tighten setscrews and replace condenser-fan assembly.

Proceed as follows:
1. Remove caps from low-pressure and high-pressure
Schrader valve fittings.
2. Using hoses with valve core depressors, attach low- and
high-pressure gage hoses to low-pressure and highpressure service fittings, respectively.
3. Start unit in Cooling mode and let unit run until system
pressure stabilize.
4. Measure and record the following:
a. Outdoor ambient-air temperature (F db).
b. Evaporator inlet-air temperature (F wb).
c. Suction-tube temperature (F) at low-side service
fitting.
d. Suction (low-side) pressure (psig).
FAN HEIGHT “A” (in.)

5. Using “Cooling Charging Charts” compare outdoor-air
temperature (F db) with the suction line pressure (psig) to
determine desired system operating suction line temperature. See Fig. 49-56.
6. Compare measured suction-tube temperature with desired suction-tube temperature. Using a tolerance of
± 3° F, add refrigerant if measured temperature is more
than 3° F higher than proper suction-tube temperature, or
remove refrigerant if actual temperature is more than 3° F
lower than required suction-tube temperature.
TO USE COOLING CHARGING CHART — This method
is to be used in Cooling mode only. Take the outdoor ambient
temperature and read the suction pressure gage. Refer to
appropriate chart to determine what suction temperature
should be. If suction temperature is high, add refrigerant. If
suction temperature is low, carefully recover some of the
charge. Recheck the suction pressure as charge is adjusted.

***Modulation is based on the greater of DCV and supply air sensor
signals, between minimum position and either maximum position
(DCV) or fully open (supply air signal).
†††Modulation is based on the greater of DCV and supply air
sensor signals, between closed and either maximum position
(DCV) or fully open (supply air signal).
*For single enthalpy control, the module compares outdoor
enthalpy to the ABCD set point.
†Power at N terminal determines Occupied/Unoccupied setting:
24 vac (Occupied), no power (Unoccupied).
**Modulation is based on the supply air sensor signal.
