START-UP CHECKLIST
FOR 30XW LIQUID CHILLERS . . . . . . . .CL-1 to CL-7
Electrical shock can cause personal injury and death. Shut
off all power to this equipment during installation and service. There may be more than one disconnect switch. Tag
all disconnect locations to alert others not to restore power
until work is completed.
WARNING
DO NOT VENT refrigerant relief valves within a building.
Outlet from relief valves must be vented in accordance
with the latest edition of ANSI/ASHRAE (American
National Standards Institute/American Society of Heating,
Refrigerating and Air Conditioning Engineers) 15 (Safety
Code for Mechanical Refrigeration). The accumulation of
refrigerant in an enclosed space can displace oxygen and
cause asphyxiation. Provide adequate ventilation in
enclosed or low overhead areas. Inhalation of high concentrations of vapor is harmful and may cause heart irregularities, unconsciousness or death. Misuse can be fatal. Vapor
is heavier than air and reduces the amount of oxygen available for breathing. Product causes eye and skin irritation.
Decomposition products are hazardous.
WARNING
DO NOT USE TORCH to remove any component. System
contains oil and refrigerant under pressure.
To remove a component, wear protective gloves and goggles and proceed as follows:
a. Shut off electrical power to unit.
b. Recover refrigerant to relieve all pressure from system using both high-pressure and low pressure ports.
c. Traces of vapor should be displaced with nitrogen
and the work area should be well ventilated. Refrigerant in contact with an open flame produces toxic
gases.
d. Cut component connection tubing with tubing cutter
and remove component from unit. Use a pan to catch
any oil that may come out of the lines and as a gage
for how much oil to add to the system.
e. Carefully unsweat remaining tubing stubs when necessary. Oil can ignite when exposed to torch flame.
Failure to follow these procedures may result in personal
injury or death.
CAUTION
DO NOT re-use compressor oil or any oil that has been
exposed to the atmosphere. Dispose of oil per local codes
and regulations. DO NOT leave refrigerant system open to
air any longer than the actual time required to service the
equipment. Seal circuits being serviced and charge with
dry nitrogen to prevent oil contamination when timely
repairs cannot be completed. Failure to follow these procedures may result in damage to equipment.
SAFETY CONSIDERATIONS
Installing, starting up, and servicing this equipment can be
hazardous due to system pressures, electrical components, and
equipment location. Only trained, qualified installers and service technicians should install, start up, and service this equipment. When working on this equipment, observe precautions in
the literature, on tags, stickers, and labels attached to the equipment, and any other safety precautions that apply. Follow all
safety codes. Wear safety glasses and work gloves. Use care in
handling, rigging, and setting this equipment, and in handling
all electrical components.
CAUTION
This unit uses a microprocessor-based electronic control
system. Do not use jumpers or other tools to short out
components, or to bypass or otherwise depart from recommended procedures. Any short-to-ground of the control board or accompanying wiring may destroy the
electronic modules or electrical components.

show an expanded description of the point name. To view the expanded point name for the Touch Pilot™ display refer to Appendix A.
CAUTION
To prevent potential damage to heat exchanger tubes,
always run fluid through heat exchanger when adding or
removing refrigerant charge. Use appropriate antifreeze
solutions in evaporator and condenser fluid loops to prevent the freezing of heat exchangers or interconnecting piping when the equipment is exposed to temperatures below
32 F (0° C). Proof of flow switch is factory installed on all
models. Do NOT remove power from this chiller during
winter shut down periods without taking precaution to
remove all water from heat exchangers. Failure to properly
protect the system from freezing may constitute abuse and
may void warranty.
The Touch Pilot™ display configures the unit via the CCN
(Carrier Comfort Network®) Tables, which are located in Appendix C of this manual.

screens show status information along the top of the screens
and 9 buttons that display 9 point names and point values that
are chosen by the user. All Group Display screen points are
user configurable. The bottom line of the screen contains navigation buttons that can be used to move between the Group
Display screens.
Pressing a point button will show that point’s Point Data
dialog box. See Fig. 2 and 3. This box contains buttons that
remove the point from the group display and apply or remove a
force (point override). When touching any button in the display
screen, the button will be outlined to acknowledge input. There
may be a delay in response to input, but if the button is outlined, do NOT press any other button until the previous input
has been processed.
If there is a communication failure with the MBB (Main
Base Board), all point buttons will be displayed in inverse video and the message Communication Failure will be displayed
in the top left line of the screen.
Default Group Designation — The default group is the first of
the 8 Group Display screens. This is the default screen of the
display. Information on this screen as well as the other 7
screens can be user-modified to meet the needs of the site.
To Add a Point to a Group Display — From the Main Menu,
press the desired menu button (Status, Setpoint, Service,
Maint, or Config) and, if necessary, the sub-menu button to
access the point to be added. Press the point button to show the
source point’s Point Data dialog box. See Fig. 3. From the
Point Data dialog box, press the ADD button. The display will
show the last Group Display accessed. Use the navigation buttons to access the destination Group Display. Press an existing
point button or a blank button to update the highlighted button
When a specific item is located, the item name appears on

If the Navigator™ module is connected to a Main Base
Board without software loaded, the display will remain at the
powered-up initialization display.
Setting the Time and Date — The ComfortLink control has a
time and date function. This can be useful for diagnostics to determine when alarms occur. The control is factory configured
for the proper date and for use in the Eastern Time Zone. The
control must be checked and corrected if necessary. The correct
time is important if the machine is to function on an internal
time schedule and display a proper time and date stamp for
alarms. The time and date will be displayed on the default rotating display of the Navigator™ module. The time and date
can also be checked and changed under the Time Clock mode
as described below.

machine. See Fig. 8. The MBB continuously monitors input/
output channel information received from its inputs and from
all other modules. The MBB receives inputs from status and
feedback switches, pressure transducers and thermistors. The
MBB also controls several outputs. Some inputs and outputs
that control the chiller are located on other boards, but are
transmitted to or from the MBB via the internal communications bus. Information is transmitted between modules via a
3-wire communication bus or LEN (Local Equipment Network). The CCN (Carrier Comfort Network®) bus is also supported. Connections to both LEN and CCN buses are made at
TB3. For a complete description of Main Base Board inputs
and outputs and their channel identifications, see Table 3.

Energy Management Module (EMM) — The EMM
Enable-Off-Remote Contact Switch (SW1) —
is available as a factory-installed option or as a field-installed
accessory. See Fig. 12. The EMM receives 4 to 20 mA inputs
for the temperature reset, cooling set point and demand limit
functions. The EMM also receives the switch inputs for the
field-installed second stage 2-step demand limit and ice done
functions. The EMM communicates the status of all inputs
with the MBB, and the MBB adjusts the control point, capacity
limit, and other functions according to the inputs received. See
Table 9.
This switch is installed in all units and provides the owner and
service person with a local means of enabling or disabling the
machine. It is a 3-position switch and it is used to control the
chiller. When switched to the Enable position, the chiller will
be under its own control. When switched to the Off position,
the chiller will shut down. When switched to the Remote Contact position, a field-installed dry contact can be used to start
the chiller. The contacts must be capable of handling a 24-vac,
50-mA load. In the Enable and Remote Contact (dry contacts
closed) positions, the chiller is allowed to operate and respond
to the scheduling configuration, CCN configuration, and set
point data.
For units with a Touch Pilot™ display, the position of the
Enable/Off/Remote contact switch is ignored except when the
Remote Mode operating type is selected. Refer to the Machine
Control Methods section on page 20 for more details.
CAUTION
Care should be taken when interfacing with other manufacturer’s control systems due to possible power supply differences, full wave bridge versus half wave rectification,
which could lead to equipment damage. The two different
power supplies cannot be mixed. ComfortLink controls use
half wave rectification. A signal isolation device should be
utilized if incorporating a full wave bridge rectifier signal
generating device is used.
Emergency On/Off Switch (SW2) — This switch is
installed in all units. The Emergency On/Off switch should
only be used when it is required to shut the chiller off immediately. Power to all modules is interrupted when this switch is
off and all outputs from these modules will be turned off.

communication errors at the board connectors. See input/output Tables 3-10 for LEN connector designations. A 3-wire bus
accomplishes communication between modules. These 3 wires
run in parallel from module to module. The J9A connector on
the MBB provides communication directly to the Navigator™
display module.
YELLOW LED — The MBB has one yellow LED. The
Carrier Comfort Network® (CCN) LED will blink during times
of network communication.
Local Equipment Network — Information is transmitted between modules via a 3-wire communication bus or
LEN (Local Equipment Network). External connection to the
LEN bus is made at TB3.
Board Addresses — All boards (except the Main Base
Board and Energy Management Module Board) have
8-position DIP switches.
Touch Pilot™ Display — The Touch Pilot™ display
port connections are shown in Table 10. Wiring is shown in
Fig. 13.

RED LED — Proper operation of the control boards can be
visually checked by looking at the red status LEDs (lightemitting diodes). When operating correctly, the red status
LEDs will blink in unison at a rate of once every 2 seconds. If
the red LEDs are not blinking in unison, verify that correct
power is being supplied to all modules. Be sure that the Main
Base Board (MBB) is supplied with the current software. If
necessary, reload current software. If the problem still persists,
replace the MBB. A red LED that is lit continuously or blinking at a rate of once per second or faster indicates that the board
should be replaced.
GREEN LED — All boards have a green LEN LED which
should be blinking whenever power is on. If the LEDs are not
blinking as described check LEN connections for potential

To connect the unit to the network:
1. Turn off power to the control box.
2. Cut the CCN wire and strip the ends of the red (+), white
(ground), and black (–) conductors. (Substitute appropriate colors for different colored cables.)
3. Connect the red wire to (+) terminal on TB3 of the plug,
the white wire to COM terminal, and the black wire to the
(–) terminal.
4. The RJ14 CCN connector on TB3 can also be used, but is
only intended for temporary connection (for example, a
laptop computer running Service Tool).
Carrier Comfort Network® (CCN) Interface —
All 30XW units can be connected to a CCN system, if desired.
The communication bus wiring is a shielded, 3-conductor cable
with drain wire and is field supplied and installed. The system
elements are connected to the communication bus in a daisy
chain arrangement. The positive pin of each system element
communication connector must be wired to the positive pins of
the system elements on either side of it. The negative and signal ground pins of each system element must also be wired in
the same manner. Wiring connections for CCN should be made
at TB3. Consult the CCN Contractor’s Manual for further information. See Fig. 14.
NOTE: Conductors and drain wire must be 20 AWG (American Wire Gage) minimum stranded, 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. See Table 11 for recommended wire
manufacturers and part numbers.
IMPORTANT: A shorted CCN bus cable will prevent
some routines from running and may prevent the unit
from starting. If abnormal conditions occur, disconnect the CCN bus. If conditions return to normal,
check the CCN connector and cable. Run new cable if
necessary. A short in one section of the bus can cause
problems with all system elements on the bus.
Table 11 — CCN Communication Bus Wiring
It is important when connecting to a CCN communication
bus that a color-coding scheme be used for the entire network
to simplify the installation. It is recommended that red be used
for the signal positive, black for the signal negative, and white
for the signal ground. Use a similar scheme for cables containing different colored wires.
At each system element, the shields of its communication
bus cables must be tied together. If the communication bus is
entirely within one building, the resulting continuous shield
must be connected to a ground at one point only. If the communication bus cable exits from one building and enters another,
the shields must be connected to grounds at the lightning
suppressor in each building where the cable enters or exits the
building (one point per building only).

Remote Alarm and Alert Relays — The 30XW
chiller can be equipped with a remote alert and remote alarm
annunciator contacts. Both relays connected to these contacts
must be rated for a maximum power draw of 10 va sealed,
25 va inrush at 24 volts. The alarm relay, indicating that the
complete unit has been shut down, can be connected to TB5-12
and TB5-13. Refer to unit wiring diagrams. For an alert relay,
indicating that at least 1 circuit is off due to the alert, a fieldsupplied and installed relay must be connected between MBBJ3-CH25-3 and TB5-13. The action of the alarm and alert relays can be reversed from normally open to normally closed by
using the Reverse Alarms Relay configuration (Reverse
Alarms Relay, RV.AL).

Machine On/Off Control — Machine On/Off control
depends on which interface display is used. The control is different for Touch Pilot™ or Navigator™ displays. Select the
correct configuration procedure below based on which interface is being used.
TOUCH PILOT™ MACHINE CONTROL — Machine On/
Off control is determined locally by pushing the Start/Stop button on the Touch Pilot™ display. Pressing this button will
cause the Equipment Start screen to be displayed. See Fig. 15.
Fig. 15 — Equipment Start Screen
20
Schedule 2 is used for Dual Set Point/Occupied-Unoccupied set point control. The control will ignore the position of
Enable/Off/Remote Contact switch and all CCN network force
commands, except the Emergency Stop Command.
The Run Status variable will indicate the current status of
the machine — OFF, RUNNING, DELAY, or READY. The
Chiller Occupied? variable will indicate the occupied state of
the machine according to Time Schedule 1 and will be either
YES (occupied) or NO (unoccupied). The Control Type variable will indicate the type of control. For this configuration,
Control Type will be Local. The Operating Type variable
will change to L-Sched (Local Schedule).
The schedules consist of 8 user-configurable occupied time
periods. The control supports time schedules for local control,
remote control, and ice building. These time periods can be
flagged to be in effect or not in effect on each day of the week.
The day begins at 00.00 and ends at 24.00. The machine will be
in unoccupied mode unless a scheduled time period is in effect.
If an occupied period extends past midnight, the occupied
period will automatically end at 24:00 hours (midnight) and the
new occupied period must be programmed to begin at 00:00
hours.
In the following example, the occupied period starts at 6:00
AM, Monday through Friday and 10:00 AM on Saturday and
Sunday. The occupied time ends at 6:30 PM on Monday
through Friday and 2:00 PM on Saturday and Sunday. See
Fig. 16.
NOTE: This schedule was designed to illustrate the programming of the schedule function and is not intended as a
recommended schedule for chiller operation.
If the chiller is to be controlled to a single set point, use
Schedule 1 (OCCPC01S). This will start and stop the machine.
During the unoccupied times, the chiller will be off. If the chiller is to be controlled to 2 set points, occupied and unoccupied,
use Schedule 2 (OCCPC02S). This will cause the chiller to
control to an occupied set point and an unoccupied set point.
The machine will be able to provide cooling at any time.
To configure the local schedule on the Touch Pilot™
display see Table 15.
Table 14 summarizes the unit control type and stop or go
status with regard to the following parameters:
• Operating type: this is selected by using the start/stop button
on the front of the user interface.
• Remote start/stop contacts: these contacts are used when the
unit is in remote operating type (Remote mode).
• CHIL_S_S: this network command variable relates to the
chiller start/stop when the unit is in CCN control (CCN
mode). When this variable forced to Disable, then the unit is
stopped. When this variable is forced to Enable, then the
unit runs in accordance with schedule 1.
• Start/Stop schedule: occupied or unoccupied status of the
unit as determined by the chiller start/stop program (Schedule 1).
• Master control type: This parameter is used when the unit is
the master unit in a two chiller lead/lag arrangement. The
master control type determines whether the unit is to be
controlled locally, remotely or through CCN (this parameter
is a Service configuration).
• CCN emergency shutdown: if this CCN command is activated, it shuts the unit down whatever the active operating
type.
• General alarm: the unit is totally stopped due to failure.
Local Mode — To start the machine in local mode, press the
Start/Stop button on the Touch Pilot™ display. The Equipment
Start screen will be displayed. Select Local On. The control
will ignore the position of Enable/Off/Remote Contact switch
and all CCN network force commands, except an Emergency
Stop Command. The Run Status variable, indicating the current status of the machine, will change to RUNNING, DELAY
or READY. The Chiller Occupied? variable will change to
YES. The Control Type variable indicates the type of control.
For this configuration, Control Type will be Local. The Operating Type variable will change to L-On (Local On).
Local Schedule — To start the machine with a local schedule,
press the Start/Stop button on the Touch Pilot™ display. The
Equipment Start screen will be displayed. Select Local Schedule. The unit will start and stop according to the schedule defined in the Time Schedule menu. Two Internal Time Schedules are available and must be field programmed. Time
Schedule 1 is used for single set point On-Off control. Time

CCN Global Time Schedule — A CCN global schedule can
be used if desired. The schedule number can be set anywhere
from 65 to 99 for operation under a CCN global schedule. The
30XW chillers can be configured to follow a CCN Global
Time Schedule broadcast by another system element. The
ComfortVIEW™ Network Manager’s Configure and Modify
commands or the Service Tool’s Modify/Names function must
be used to change the number of the Occupancy Equipment
Part Table Name (OCC1P01E) to the Global Schedule Number. The Schedule Number can be set from 65 to 99
(OCC1P65E to OCC1P99E).
The Occupancy Supervisory Part table name (OCC1P01S)
number must be changed to configure the unit to broadcast a
Global Time Schedule. The Schedule Number can be set from
65 to 99 (OCC1P65S to OCC1P99S). When OCC1PxxS is set
to a value greater than 64, an occupancy flag is broadcast over
the CCN every time it transitions from occupied to unoccupied
or vice-versa. By configuring their appropriate Time Schedule
decisions to the same number, other devices on the network can
follow this same schedule. The Enable/Off/Remote Contact
must be in the Enable position or the Remote Contact position
with the contacts closed for the unit to operate. The Unit Run
Status (STAT) will indicate the current status of the machine
(OFF, RUNNING, STOPPING or DELAY), depending on the
schedule. The unit Occupied status (OCC) will indicate the
current occupied schedule according to the schedule, either NO
or YES. The Status Unit Control Type (CTRL) will be LOCAL
OFF when the switch is Off. The Status Unit Control Type will
be CCN when the Enable/Off/Remote Contact switch input is
On.
Refer to Appendix F for more detailed instructions regarding global schedules and the i-Vu® device.
CCN Mode — To allow machine control by CCN commands,
press the Start/Stop button on the Touch Pilot™ display. The
Equipment Start screen will be displayed. Select CCN Mode.
The unit will be controlled by a CCN command to the CCN
Chiller Start/Stop variable. An external CCN device, such as
Chillervisor, controls the On/Off state of the machine. When
controlled by a Chillervisor, it is recommended that the Auto
Start When SM Lost configuration be set to Yes. In the event
of a loss of communication with the network, the machine will
start and be controlled locally.
Careful evaluation of chilled water plant control should be
reviewed. In the event local control is established, be sure that
all pumps, valves, and other devices are capable of operating
properly. The control will ignore the position of Enable/Off/
Remote Contact switch. The Run Status variable will indicate
the current status of the machine — OFF, RUNNING, DELAY,
or READY. The Control Type variable will change to CCN.
The Operating Type variable will change to CCN.
For dual chiller control applications, the slave chiller must
be enabled using the CCN Mode button.
Remote Mode — To allow machine to start and stop via a
remote contact closure, press the Start/Stop button on the
Touch Pilot™ display. The Equipment Start screen will be displayed. Select Remote Mode. The unit will be controlled by the
Enable/Off/Remote Contact switch (SW1). Switching the Enable/Off/Remote Contact switch to the Enable or Remote

NAVIGATOR™ DISPLAY MACHINE CONTROL — Machine On/Off control with the Navigator™ display is determined by the configuration of the Operating Type Control
(OPER). Options to control the machine locally via a switch,
from a local Time Schedule, or via a Carrier Comfort Network® command are offered. See Table 17.
The schedules consist of 8 user-configurable occupied time
periods. The control supports time schedules for local control,
remote control, and ice building. These time periods can be
flagged to be in effect or not in effect on each day of the week.
The day begins at 00.00 and ends at 24.00. The machine is in
unoccupied mode unless a scheduled time period is in effect. If
an occupied period is to extend past midnight, the occupied
period must end at 24:00 hours (midnight) and a new occupied
period must be programmed to begin at 00:00 hours.
In the following example, a early morning pulldown time
period is scheduled for Monday morning from 12:00 AM to
3:00 AM. The occupied period starts at 7:00 AM, Monday
through Saturday. The occupied time ends at 6:00 PM on Monday and Tuesday, 9:30 PM on Wednesday, 5:00 PM on Thursday and Friday, and 12:00 PM on Saturday.
NOTE: This schedule was designed to illustrate the programming of the schedule function and is not intended as a recommended schedule for chiller operation.
Switch Control — In the Switch Control operating type, the
Enable/Off/Remote Contact switch controls the machine locally. All models are factory configured with Operating Type
Control (OPER) set to SWITCH CTRL (Switch Control).
With SWITCH CTRL, switching the Enable/Off/Remote
Contact switch to the Enable or Remote Contact position (external contacts closed) will put the chiller in an occupied state.
The Unit Run Status (STAT) will indicate the current status of
the machine and will change from OFF to RUNNING or
DELAY. The unit Occupied Status (OCC) will change from
NO to YES. The Status Unit Control Type (CTRL) will change
from LOCAL OFF when the switch is Off to LOCAL ON
when in the Enable position or in the Remote Contact position
with external contacts closed.

ignored. The Run Status variable will indicate the current status of the machine (OFF, RUNNING, DELAY, or READY),
depending on the position of the Remote/Off/Enable Switch
closure. The Chiller Occupied? variable will change to YES.
The Control Type variable will change to Remote. The Operating Type variable will change to Remote.
Master Mode — To activate Dual Chiller Control, each machine must be individually configured for Dual Chiller Control.
To operate the machines in Dual Chiller Mode, one machine
must be designated as the master unit and one machine as the
slave unit. On the master unit, press the Start/Stop button on the
Touch Pilot™ display. The Equipment Start screen will be displayed. Select Master Mode. Failure to start the Master unit in
this manner will cause both machines to operate in local mode.
The Master Unit Control can be done locally, remotely or
through CCN commands per the master/slave configuration
(Master Control Type). The control will ignore the position of
Enable/Off/Remote Contact switch if the Master Control
Type is configured for Local Control or CCN Control. The
Run Status variable, Chiller Occupied? variable, and Control Type variable will change based on the Master Control
Type configured above and the Machine On/Off Control defined above. The Operating Type variable will change to
Master.
To Turn Machine Off — To turn the machine off, press the
Start/Stop button on the Touch Pilot™ display. See Fig. 17.
The machine will shut down. While the unit is in Local Off, it
will remain shut down and ignore all CCN commands as well
as the position of Enable/Off/Remote Contact switch. The Run
Status variable, indicating the current status of the machine,
will change to OFF. The Chiller Occupied? variable will
change to NO. The Control Type variable will indicate
Local. The Operating Type variable will change to L-OFF
(Local Off).

If the chiller is to be controlled to a single set point, use
Schedule 1 (SCH1). This type of schedule will start and stop
the machine only. During the unoccupied times, the chiller will
be off. If the chiller is to be controlled to 2 set points, occupied
and unoccupied, use Schedule 2 (SCH2). This will cause the
chiller to control to an occupied set point and an unoccupied set
point. The machine will be able to provide cooling at any time.
To configure this option while using the Navigator™ display, see Table 18.
Holiday Schedule — The unit control allows up to 16 holiday
periods. All holidays are entered with numerical values. First
enter the month (MON.x), then the day (DAY.x), then the
duration (DUR.x) of the holiday period in days. If a holiday in
included in one of the Occupied Time Periods of the schedule,
the machine will follow that operating condition for the
holiday. In the following examples, the holidays July 4 and
December 25-26 are programmed for Holiday 1 and Holiday 2
respectively.
To configure this option for the Navigator™ display, see
Table 19.
CCN Global Time Schedule — A CCN global schedule can
be used if desired. The schedule number can be set anywhere
from 65 to 99 for operation under a CCN global schedule. The
30XW chillers can be configured to follow a CCN Global
Time Schedule broadcast by another system element. The
ComfortVIEW™ Network Manager’s Configure and Modify

The Occupancy Supervisory Part table name (OCC1P01S)
number must be changed to configure the unit to broadcast a
Global Time Schedule. The Schedule Number can be set from
65 to 99 (OCC1P65S to OCC1P99S). When OCC1PxxS is set
to a value greater than 64, an occupancy flag is broadcast over
the CCN every time it transitions from occupied to unoccupied
or vice-versa. By configuring their appropriate Time Schedule
decisions to the same number, other devices on the network can
follow this same schedule. The Enable/Off/Remote Contact
must be in the Enable position or the Remote Contact position
with the contacts closed for the unit to operate. The Unit Run

Heat/Cool Select (HC.SE) = 1 (Heating) allows the unit to
operate in the heating mode only.
Heat/Cool Select (HC.SE) = 3 (Heat Cool Sw) allows the
unit to switch between cooling and heating based on a dry contact input (open contacts = Cool, closed contacts = Heat). Use
of the Heat/Cool switch option requires field installed wiring to
Main Base Board input channel 14. Refer to 30XW wiring diagram in Service Test section. Heat/Cool Select can also be
forced from communications (CCN point name HC_SEL).
To configure these options for the Touch Pilot™ display, see
Table 20A. To configure these options for the Navigator™ display, see Table 20B.
CCN Control — With CCN Operating Type control, the machine operates under CCN control as long as the Enable/Off/
Remote Contact Switch is in the Enable or Remote Contact
position (external contacts closed.) To operate under this
Operating Control, OPER must be set to CCN CONTROL. An
external CCN device, such as Chillervisor, controls the On/Off
state of the machine. When controlled by a Chillervisor, it is
recommended that the Auto Start When SM Lost (AU.SM) be
set to Yes.
Careful evaluation of Chilled Water Plant control should be
reviewed. In the event Local Control is established, be sure that
all pumps, valves, and other devices are capable of operating
properly. In the event of a loss of communication with the network, the machine will start and be controlled locally. The
CCN device forces the variable CHIL_S_S to control the chiller. The Unit Run Status (STAT) will indicate the current status
of the machine (OFF, RUNNING, STOPPING or DELAY),
depending on the CCN command. The unit Occupied status
(OCC) will indicate the current occupied state according to the
CCN command and will be displayed as either NO or YES.
The Status Unit Control Type (CTRL) will be LOCAL OFF
when the Enable/Off/Remote Contact switch is Off. The Status
Unit Control Type will be CCN when the Enable/Off/Remote
Contact switch input is Closed and the CHIL_S_S variable is
Stop or Start.
For Dual Chiller Control applications, the Slave Chiller
must be enabled using the CCN CONTROL option.

SET POINT OCCUPANCY — Set Point Occupancy is the
default configuration for the Setpoint Select variable. When
Setpoint Select (Setpoint Select, SP.SE) is configured to 0
(Setpoint Occ), the unit’s active set point is based on Cooling
Set Point 1 (Cooling Setpoint 1, CSP.1) during the occupied
period while operating under Time Schedule 1 (SCH1). If the
Time Schedule 2 (SCH2) is in use, the unit’s active set point is
based on Cooling Set Point 1 (Cooling Setpoint 1, CSP.1) during the occupied period and Cooling Set Point 2 (Cooling Setpoint 2, CSP.2) during the unoccupied period. See Tables 23A
and 23B.
To configure this option while using a Touch Pilot display:
In all cases, there are limits on what values are allowed for
each set point. These values depend on the Cooler Fluid Type

30XW chillers operating as heat machines exist for controlling
the Leaving Condenser Water Set Point and are configured by
the Set Point Select (Setpoint Select, SP.SE) variable. In addition, the Heat Cool Select (Heat/Cool Select, HC.SE) variable
also has a role in determining the set point of the machine. All
units are shipped from the factory with the Heat/Cool Select set
to 0.
All default set points are based on Leaving Water Control
(Entering Fluid Control, EWTO) set to No. Values must be
confirmed for the individual set points. Limits for the set points
are listed in the configurations noted below.
To configure these options for the Touch Pilot™ display, see
Table 24A. If the chiller will be run in the Local mode, change
the Heat/Cool Select to a value of 1. If desired, the Touch
Pilot™ display can be configured for remote mode operation.
For this mode, use the remote/off/enable switch for chiller operation. This mode also requires that the heat/cool switch input
be wired. The chiller will be in cooling mode with an open
switch input and heating mode when this switch input is
closed.
To configure these options for the Navigator™ display, see
Table 24B.
The Setpoint Select configuration can be set to five different
control options: Set Point Occupancy, Set Point 1, Set Point 2,
4-20 mA Input, and Dual Switch.

the chilled water pump interlock contact (connected across
TB5 terminals 1 and 2) are required. In addition, for Cooler
Pumps Sequence settings of PUMP = 1, 2, 3, 4, normally open
auxiliary contacts for Pump 1 and Pump 2 (wired in parallel)
must be connected to the violet and pink wires located in the
harness from the MBB-J5C-CH18 connector. The wires in the
harness are marked "PMP1-13" and "PMP1-14". See the field
wiring diagram in the 30XW Installation Instructions.
Regardless of the cooler pump control option selected, if the
chilled water flow switch/interlock does not close within the
Unit Off to On Delay period after the unit is enabled and in an
ON mode, alarm P.91 will be generated. Other conditions
which will trigger this alarm include:
• Cooler pump interlock is open for at least 15 seconds during
chiller operation.
• Lag chiller in Master/Slave Control pump interlock does not
close after 1 minute of the pump start command.
• Cooler pump control is enabled and the chilled water flow
switch/interlock is closed for more than 2 minutes following
a command to shut down the pump.
The last alarm criterion can be disabled. If the cooler pump
flow setting (Flow Checked if C Pmp Off, P.LOC) is set to
NO, the control will ignore the pump interlock input if the
cooler pump output is OFF.
The ComfortLink controls have the ability to periodically
start the pumps to maintain the bearing lubrication and seal integrity. If Pump Sticking Protection (Pump Sticking Protection, PM.PS) is set to YES, and if the unit is off at 2:00 PM, a
pump will be started once each day for 2 seconds. If the unit
has 2 pumps, Pump 1 will be started on even days (such as day
2, 4, or 6 of the month); Pump 2 will be started on odd days.
The default for this option is PM.PS=NO.
The pump will continue to run for 60 seconds after an off
command is issued.

Before configuring this selection, confirm that a suitable antifreeze has been added and is at a sufficient concentration to
protect the loop. Additionally, the Brine Freeze Set Point
(Brine Freeze Setpoint, LOSP) must be set for proper freeze

Cooler Pump Control — It is required for all chillers
that the cooler pump control be utilized unless the chilled water
pump runs continuously or the chilled water system contains a
suitable concentration of antifreeze solution. When the Cooler
Pumps Sequence is configured, the cooler pump output will be
energized when the chiller enters an "ON" mode. The cooler
pump output is also energized when certain alarms are generated. The cooler pump output should be used as an override to
the external pump control if cooler pump control is not utilized.
The cooler pump output is energized if a P.01 Water Exchanger
Freeze Protection alarm is generated, which provides additional freeze protection if the system is not protected with a suitable
antifreeze solution.
The 30XW units can be configured for external cooler
pump control. Cooler Pumps Sequence is the variable that
must be confirmed in the field. Proper configuration of the
cooler pump control is required to provide reliable chiller operation. The factory default setting for Cooler Pumps Sequence is
0 (No Pump). The configuration settings for Cooler Pumps Sequence are 1 (1 pump only) for single pump control and 2 (2
pumps auto). Configuration settings 3 (PMP 1 Manual) and 4
(PMP 2 Manual) are for dual pump control only.
If the Cooler Pumps Sequence (PUMP) is set to 1, the control will start the pump. If a flow failure is detected, the unit
will shut down and must be manually reset. If the Cooler
Pumps Sequence (PUMP) is set to 2, the control will start the
lead pump and automatically alternate the operation of the
pumps to even the wear. If a flow failure is detected, the unit
will shut down and the lag pump will attempt to start. If flow is
established within the Unit Off to On Delay (DELY) period the
unit will restart automatically.
Two manual control options are also available. When the
Cooler Pumps Sequence (PUMP) is set to 3, Cooler Pump 1
will always operate. If a flow failure is detected, the unit will
shut down and must be manually reset. When the Cooler
Pumps Sequence (PUMP) is set to 4, Cooler Pump 2 will always operate. If a flow failure is detected, the unit will shut
down and must be manually reset.

Circuit/Compressor Staging and Loading —
The AquaForce® 30XW chillers employ one compressor per
circuit. As a result, circuit and compressor staging are the
same. The control has several control option parameters to load
the compressors. The circuit/compressor start can be configured as well as the loading of each circuit/compressor.
CIRCUIT/COMPRESSOR STAGING — The control can be
configured to decide which circuit/compressor starts first, by
configuring Lead/Lag Circuit Select (Circuit Loading
Sequence, LLCS). Three options for this variable are allowed:
Automatic Lead-Lag, Circuit A Leads or Circuit B Leads. The
factory default is Automatic Lead-Lag.
The automatic lead-lag function determines which circuit/
compressor starts. When enabled, the control will determine
which circuit/compressor starts to even the wear of the compressor. The compressor wear factor (combination of starts and
run hours) is used to determine which compressor starts.
Compressor Wear Factor = (Compressor Starts) + 0.1 (Compressor Run Hours)
The circuit/compressor with the lowest compressor wear
factor is the circuit that starts first.
If starting a particular circuit/compressor first is desired, that
can also be configured with the same variable.

the machine is also available. This parameter is useful in keeping multiple machines from starting at the same time in case of
a power failure. The parameter has a factory default of
1 minute. This parameter also has a role in the timing for a
chilled water flow switch alarm. The flow switch status is not
checked until the delay time has elapsed.
To configure this option with the Touch Pilot™ display:
be configured for condenser pump control. When configured,
the condenser pump output will be energized when the chiller
enters an "ON" mode. The condenser pump output is also energized if either circuit's saturated condensing temperature falls
below 34 F (1.1 C). A field-installed condenser flow switch input is required when using condenser pump control. The flow
switch input is connected to Channel 16A of the Main Base
Board (MBB-J5A connector). There is a factory-installed
jumper wire on this channel that must be cut. Connect flow
switch output signal wire to cut jumper wire connected to the
main base board pin marked "CH 16A." Install wire nut on other end of cut jumper wire. Condenser flow switch requires 24v
power to be taken from the load side of CB1. Refer to the 24v
and 115v control wiring diagrams for flow switch wiring
marked as device "CDFS."
The variable Condenser Pumps Sequence must be configured to enable pump control. The factory default setting for
Condenser Pumps Sequence is 0 (No Pump). The only configuration setting choice for Condenser Pumps Sequence is 1 (1
pump only). With the Condenser Pumps Sequence (HPUM)
set to 1, the control will start the pump. If a flow failure is
detected, the unit will shut down and must be manually reset. If
the condenser flow switch does not close within 1 minute after
pump start command or is open for at least 15 seconds during
chiller operation, alarm P.15 will be generated. The pump will
continue to run for 60 seconds after an off command is issued.

On both chillers, Master/Slave Select (Master/Slave Select,
MSSL) must be enabled. The water piping arrangement, Chillers in Series (Chiller in Series, SERI), must be configured.
The master chiller must be programmed with the Slave Chiller
Address (Slave Address, SLVA). Additional optional programming parameters may be configured to meet application
requirements.
Lead/Lag Balance Select (Lead Lag Select, LLBL) determines which chiller is the lead machine. The options are Always Lead, Lag if Fail, and Runtime Select. Under Runtime
Select control, the lead chiller will change based on the time increment selected in the Lead/Lag Balance Delta configuration
(Lead/Lag Balance Delta, LLBD). If the run hour difference
between the master and the slave remains less than the Lead/
Lag Balance Delta, the chiller designated as the lead will
remain the lead chiller. The Lead/Lag changeover between the
master and the slave chiller due to hour balance will occur during chiller operating odd days, such as day 1, day 3, and day 5
of the month, at 12:00 a.m. If a lead chiller is not designated,
the master chiller will always be designated the lead chiller.
The dual chiller control algorithm has the ability to delay
the start of the lag chiller in two ways. The Lead Pulldown
Time parameter (Lead Pulldown Time, LPUL) is a one-time
time delay initiated after starting the lead chiller, before
checking whether to start an additional chiller. This time delay
gives the lead chiller a chance to remove the heat that the
chilled water loop picked up while being inactive during an unoccupied period. The second time delay, Lead/Lag Delay (Lag
Start Timer, LLDY) is a time delay imposed between the last
stage of the lead chiller and the start of the lag chiller. This prevents enabling the lag chiller until the lead/lag delay timer has
expired.
A quicker start of the lag chiller can be accomplished by
configuring the Start if Error Higher parameter (Start if Error
Higher, LL.ER). If the difference between the common leaving water temperature and the set point is greater than the configured value, then the lag chiller will start.
A minimum on time for the lag chiller can be programmed
with the Lag Minimum Running Time configuration (Lag
Minimum Running Time, LAG.M). This parameter causes
the control to run the lag chiller for the programmed minimum
on time. The Lag Unit Pump Select (Lag Unit Pump Control,
LAGP) can be configured such that the pump can be on or off
while the chiller is off. This parameter is only active in Parallel
Chiller Operation.
For units with a Touch Pilot™ display, two additional steps
must be completed to start the machine. On the master chiller,
the Master Control Type must be configured for the start control defined in the Machine Control configuration. To start the
machines, the master chiller must be started with the Start/Stop
button and Master Mode selected. The slave chiller must be
started with the CCN Mode selected.
Each application, Parallel and Series, are described separately below.
DUAL CHILLER CONTROL FOR PARALLEL APPLICATIONS — To configure the master chiller for parallel
applications using the Touch Pilot™ display, see Table 25. To
configure the master chiller for parallel applications using the
Navigator™ display, see Table 26.
To configure the slave chiller for parallel applications using
the Touch Pilot™ display, see Table 27. To configure the slave
chiller for parallel applications using the Navigator™ display,
see Table 28.
DUAL CHILLER PUMP CONTROL FOR PARALLEL
CHILLER APPLICATIONS — It is recommended that a
dedicated pump be used for each unit. The chiller must start
and stop its own water pump located on its own piping. If
pumps are not dedicated for each chiller, chiller isolation
CIRCUIT/COMPRESSOR LOADING — The control can
be configured to stage the circuit/compressors. The Loading
Sequence Select (Staged Loading Sequence, LOAD) setting
determines how the control will perform loading. The configuration can be set to Equal or Staged.
Equal Loading — With Equal loading, the lead circuit will
start and maintain the minimum stage of capacity with the slide
valve fully unloaded. As additional capacity is required, the
slide valve will be adjusted in approximately 5% increments to
match capacity requirements. The lag circuit will not start until
the lead circuit reaches 70% capacity. The lead circuit will remain at 70% and the lag circuit will increase in capacity until it
also reaches 70% capacity. The control will alternate between
circuits to maintain the same percentage of capacity on each
circuit until they reach 100%.
Staged Loading — If staged loading is selected, the lead circuit will start and maintain the minimum stage of capacity with
the slide valve fully unloaded. As additional capacity is required, the slide valve will be adjusted in approximately 5% increments to match capacity requirements until the circuit is fully loaded. Once the circuit is fully loaded and additional capacity is required, the control will start the lag circuit fully
unloaded. The control will continue load the lag circuit in approximately 5% increments to match capacity requirements
until both circuits reach 100% capacity.

Dual Chiller Control — The dual chiller routine is
available for the control of two units installed in series or parallel supplying chilled fluid on a common loop. One chiller must
be configured as the master chiller, the other as the slave chiller. For parallel applications, an additional leaving fluid temperature thermistor (dual chiller LWT) must be installed in the
common chilled water piping as described in the Installation
Instructions for both the master and slave chillers. See the Field
Wiring section in the 30XW Installation Instructions for dual
chiller LWT sensor control wiring.
The control algorithm relies on several parameters that must
be field configured for operation. Both chillers must be on the
same Carrier Comfort Network® bus with different addresses.

DUAL CHILLER PUMP CONTROL FOR SERIES
CHILLER APPLICATIONS — Pump control for series chiller applications is controlled by the master chiller only. The
control of the slave chiller is directed through commands emitted by the master chiller. The slave chiller has no action in
master/slave operations. The slave chiller only verifies that
CCN communication with the master chiller is present. See the
Dual Chiller Sequence of Operation section on page 58.

CCN Control
Ramp Loading — Ramp Loading limits the rate of
change of the leaving fluid temperature. If the unit is in a Cooling mode and configured for Ramp Loading Select (Ramp
Loading Select, RL.S), the control makes two comparisons
before deciding to increase capacity. First, the control calculates the temperature difference between the control point and
leaving fluid temperature. If the difference is greater than 4° F
(2.2° C) and the rate of change (°F or °C per minute) is more
than the configured Cool Ramp Loading rate (Cooling Ramp
Loading, CRMP), then the control does not allow any increase
of capacity.
To configure this option with the Touch Pilot™ display:
To use Return Water Temperature Reset, four variables
must be configured. Cooling Reset Type (Cooling Reset
Select, CRST) must be enabled. The variable Delta T No Reset
Temp (Delta T No Reset Value, CRT1) should be set to the
cooler temperature difference (T) where no chilled water temperature reset should occur. The variable Delta T Full Reset
Temp (Delta T Full Reset Value, CRT2) should be set to the
cooler temperature difference where the maximum chilled
water temperature reset should occur. The variable Degrees
Cool Reset (Cooling Reset Deg. Value, DGRC) should be set
to the maximum amount of reset desired.

CRST
Temperature Reset — Temperature reset is a value
added to the basic leaving fluid temperature set point and the
resulting sum of these values is the new control point. When a
non-zero temperature reset is applied, the chiller controls to the
new control point, not the set point. The type of temperature reset is configured with the Cooling Reset Type (Cooling Reset
Select, CRST) variable. Types of temperature reset are available: Return Water Reset, Space Temperature Reset, and 4-20
mA Temperature Reset.
Under normal operation, the chiller will maintain a constant
entering or leaving fluid temperature, based on the configuration, approximately equal to the chilled fluid set point. As the
cooler load varies, the cooler fluid temperature difference will
change in proportion to the load. For example, if the chiller was
selected for a Entering to Leaving Water Temperature
difference of 10 F (5.5 C) at full load, at 50% load the temperature difference would be 5 F (2.2 C). See Fig. 19. Because the
change in temperature through the cooler is a measure of the
building load, the temperature difference reset is the average
building load. Usually the chiller size and fluid temperature set
point are selected based on a full-load condition. At part load,
the fluid temperature set point may be lower than required. If
the fluid temperature were allowed to increase at part load, the
efficiency of the machine would increase. The chiller can also
be set for return water temperature control. See Fig. 20.
Other indirect means of estimating building load and controlling temperature reset are also available and are discussed
below.
To verify that reset is functioning correctly, subtract the Setpoint Select (Current Setpoint, SETP) from the Control Point
(Control Point, CTPT) to determine the degrees reset.
RETURN WATER RESET — The control system is capable
of performing fluid temperature reset based on cooler fluid
temperature difference. Because the change in temperature
through the cooler is a measure of the building load, the temperature difference reset is, in effect, an average building load
reset method.
Return Water Temperature Reset allows for the chilled
water temperature set point to be reset upward as a function of
the fluid temperature difference (building load).
NOTE: Return Water Temperature Reset should not be used
with variable cooler flow rate systems.

In the example in Fig. 21 using Return Water Temperature
Reset, the chilled water temperature will be reset by 5° F
(2.8° C) when the Fluid Temperature Difference is 2° F
(1.1° C) and 0° F (0° C) reset when the Temperature Difference
is 10° F.
SPACE TEMPERATURE RESET — The control system is
also capable of temperature reset based on space temperature
(SPT). An accessory sensor must be used for SPT reset
(33ZCT55SPT). The Energy Management Module (EMM) is
also required for temperature reset using space temperature.
To use Space Temperature Reset, four variables must be
configured. Cooling Reset Type (Cooling Reset Select, CRST)
must be enabled. The space temperature at which no temperature reset is required, Space T No Reset Temp (Space T No
Reset Value, CRS1) must be set. The space temperature at
which full temperature reset is required, Space T Full Reset
Temp (Space T Full Reset Value, CRS2) must be set. Finally,
the amount of temperature reset desired, Degrees Cool Reset
(Cooling Reset Deg. Value, DRGC), must be set.

Care should be taken when interfacing with other control
systems due to possible power supply differences such as a
full wave bridge versus a half wave rectification. Connection of control devices with different power supplies may
result in permanent damage. The ComfortLink controls
incorporate power supplies with half wave rectification. A
signal isolation device should be utilized if the signal generator incorporates a full wave bridge rectifier.
In the space temperature reset example in Fig. 22, 0° F
(0° C) chilled water set point reset at 72 F (22.2 C) space
temperature and 6° F (3.3° C) reset at 68 F (20.0 C) space
temperature.
4-20 mA TEMPERATURE RESET — The control system is
also capable of temperature reset based on an externally powered 4 to 20 mA signal. The Energy Management Module
(EMM) is required for temperature reset using a 4 to 20 mA
signal.
To use 4-20 mA Temperature Reset, four variables must be
configured. Cooling Reset Type (Cooling Reset Select, CRST)
must be enabled. The milliamp signal at which no temperature
reset is required, Current No Reset Value (Current No Reset
Value, CRV1), must be set. The milliamp signal at which full
temperature reset is required, Current Full Reset Value (Current Full Reset Value, CRV2), must be set. Finally, the
amount of temperature reset desired, Degrees Cool Reset
(Cooling Reset Deg. Value, DRGC), must be set.

To configure this option with the Navigator™ display:
Demand Limit — Demand limit is a feature that allows
the unit capacity to be limited during periods of peak energy
usage. This allows the owner to keep energy costs down. There
are three types of demand limiting that can be configured. The
first type is through 2-step switch control, which will reduce
the maximum capacity to 2 user configurable percentages. The
second type is by 4 to 20 mA signal input which will reduce the
maximum capacity linearly between 100% at a 4 mA input
signal (no reduction) down to the user-configurable level at a
20 mA input signal. The third type uses the CCN Loadshed
module and has the ability to limit the current operating capacity to maximum and further reduce the capacity if required. Demand limit control can be based on a calculated capacity level
or by compressor current level.
SWITCH CONTROLLED DEMAND LIMIT — The control system is capable of demand limit based on a field-supplied switch for 1-step demand limit or 2 switches for 2-step
demand limit. One-step demand limit is standard. The 2-step
switch control of demand limiting requires the Energy Management Module (EMM). Demand limit steps are controlled
by two relay switch inputs field wired to TB5-5 and TB5-14
for Switch 1 and TB6-14 and TB6-15 for Switch 2.
For demand limit by switch control, closing the first demand limit contact will put the unit on the first demand limit
level, either by capacity or compressor current. The unit will
not exceed the percentage of capacity or compressor current
entered as Demand Limit Switch 1 set point. Closing contacts
on the second demand limit switch prevents the unit from exceeding the demand limit entered as Demand Limit Switch 2
set point. The demand limit percent capacity or compressor
current that is set to the lowest demand takes priority if both demand limit inputs are closed. If the demand limit percentage
does not match unit operation, the unit will limit capacity or
current to the closest step without exceeding the value.
To use demand limit, select the type of demand limiting to
use by configuring the Demand Limit Select variable (Demand Limit Type Select, DMDC) to Switch. Configure the
Demand Limit set points based on the type selected.
Switch Controlled (Capacity Based) — If using 2-step demand limit control, an energy management module must be installed. One-step demand limit control does not require the energy management module. To configure Demand Limit for
switch control, three parameters for 1-step switch control must
be configured. For 2-step control, four parameters must be
configured. The parameters are: the type of Demand Limit
Selection (Demand Limit Type Select, DMDC), the setting
for Switch Limit Set Point 1 (Switch Limit Setpoint 1, DLS1),
The setting for Switch Limit Set Point 2 (Switch Limit Setpoint 2, DLS2), and Current Limit Select (Current Limit Select, CUR.S). Current Limit Select must be set to NO.

The 4 to 20 mA signal is connected to TB6-1 and TB6-2. The
demand limit is a linear interpolation between the two values
entered. If the machine receives a 12 mA signal, the machine
controls will limit the total compressor current capacity to 1000
amps. See Fig. 25.
CCN LOADSHED CONTROLLED DEMAND LIMIT —
To configure Demand Limit for CCN Loadshed control, the
unit Operating Type Control must be in CCN control. With the
Touch Pilot™ display, the machine must be started with CCN
Control. For the Navigator™ display, the Operating Control
Type (I/O Button, OPER) must be CCN CONTROL.
The unit must be controlled by a Chillervisor module. The
Chillervisor module can force the demand limit variable and
directly control the capacity of the machine. Additionally, the
unit’s set point will be artificially lowered to force the chiller to
load to the demand limit value.

Set this variable to 2 for stand-alone units that are not connected to a CCN. With this configuration, daylight saving time
and holiday determination will be done without broadcasting
through the bus. This variable can only be changed when using
the Touch Pilot™ display, ComfortVIEW™ software, or
Network Service Tool. This variable cannot be changed with
the Navigator™ display.
To configure this option with the Touch Pilot™ display:
Broadcast Configuration — The 30XW chiller is capable of broadcasting time, date, and holiday status to all elements in the CCN system. In the stand-alone mode, broadcast
must be activated to utilize holiday schedules and adjust for
daylight saving time. If the chiller is to be connected to a CCN
system, determine which system element is to be the network
broadcaster to all other system elements. Broadcast is activated
and deactivated in the BRODEFS Table. It is accessible from
Touch Pilot™ display (Config BRODEFS) or through Network Service Tool. It is not accessible through Navigator™
display.
Only one element should be configured as a broadcaster. If
a broadcast is activated by a device that has been designated as
a network broadcaster, then broadcasted time, date, and holiday
status will be updated over the CCN system. If broadcast is enabled, a broadcast acknowledger must also be enabled. The
acknowledger cannot be the same machine as the broadcasting
machine.
ACTIVATE — The Activate variable enables the broadcast
function of the ComfortLink controls. If this variable is set to 0,
this function is not used and holiday schedules and daylight
savings compensation are not possible. Setting this variable to
1 allows the machine to broadcast and receive broadcasts on
the network. The following information is broadcast: the time
with compensation for daylight savings, date, and holiday flag.

decision. Re-alarming will continue to occur at the specified
interval until the condition causing the alarm is corrected. This
variable can only be changed with the Touch Pilot display,
ComfortVIEW software, or Network Service Tool. This variable cannot be changed with the Navigator™ display.
To configure this option with the Touch Pilot display:
Alarm Control
ALARM ROUTING CONTROL — Alarms recorded on the
chiller can be routed through the CCN. To configure this option, the ComfortLink control must be configured to determine
which CCN elements will receive and process alarms. Input for
the decision consists of eight digits, each of which can be set to
either 0 or 1. Setting a digit to 1 specifies that alarms will be
sent to the system element that corresponds to that digit. Setting all digits to 0 disables alarm processing. The factory default is 00000000. See Fig. 26. The default setting is is based
on the assumption that the unit will not be connected to a network. If the network does not contain a ComfortVIEW, ComfortWORKS®, TeLink, DataLINK™, or BAClink module, enabling this feature will only add unnecessary activity to the
CCN communication bus.
This option can be modified by the Touch Pilot display. It
cannot be modified with the Navigator™ display.

Freeze Setpoint (Brine Freeze Setpoint, LOSP) and the
circuit approach (Leaving Water Temperature – Saturated
Suction Temperature) is greater than 15º F (8.3º C) and
the Circuit Superheat (Discharge Gas Temperature – Saturated Discharge Temperature) is greater than 25º F
(13.9º C).
NOTE: The freeze set point is 34 F (1.1 C) for fresh
water systems (Cooler Fluid Type, FLUD=1). The
freeze set point is Brine Freeze Set Point (Brine Freeze
Setpoint, LOSP), for Medium Temperature Brine
systems (Cooler Fluid Type, FLUD=2).
If any of these conditions are met, the appropriate operating
mode, 21 (Circuit A) or 22 (Circuit B) will be in effect.
Override #34: Circuit A Low Refrigerant Charge
Override #35: Circuit B Low Refrigerant Charge — The capacity override attempts to protect the compressor from starting with no refrigerant in the circuit. This algorithm runs only
when the circuit is not operational (compressors is OFF). There
are several criteria that will enable this override:
1. The saturated suction temperature or saturated discharge
temperature is less than –13 F (–25 C).
2. Both of these conditions must be true:
a. The saturated suction temperature or saturated
discharge temperature is less than leaving fluid
temperature by more than 5.4º F (3.0º C).
b. Saturated suction temperature or saturated discharge temperature is less than 41 F (5 C).
3. All of these conditions must be true:
a. The saturated suction temperature or saturated
discharge temperature is less than leaving fluid
temperature by more than 5.4º F (3.0º C).
b. Saturated suction temperature or saturated discharge temperature is less than 41 F (5 C).
c. Saturated suction temperature or saturated discharge temperature is less than the brine freeze
point (Brine Freeze Setpoint, LOSP) by more
than 6º F (3.3º C).
NOTE: The freeze set point is 34 F (1.1 C)
for fresh water systems (Brine Freeze Setpoint,
FLUD=1). The freeze set point is brine freeze set
point (Brine Freeze Setpoint, LOSP), for medium
temperature brine systems (Cooler Fluid Type,
FLUD=2).
4. Both of these conditions must be true:
a. The saturated suction temperature or saturated
discharge temperature is less than leaving fluid
temperature by more than 5.4º F (3.0º C).

2. If the leaving fluid temperature is 3.6 °F (2 °C) or more
below the freeze setpoint (LOSP), the compressor capacity will be decreased when discharge gas temperature exceeds 190 F (87.8 C). If after five minutes, the discharge
gas temperature falls below 175 F (79.4 C), the compressor will be allowed to load again.
Override #69: Water-Cooled Heating Mode Low Entering
Water Temperature — This override decreases capacity if the
unit is in heating mode and the cooler leaving water temperature is below one of the two cooling setpoints. This protection
is to avoid low water temperature on cooler in heating mode.
Override #70: Water-Cooled Max Condenser LWT = 113 F
(45 C) — This override is activated only if the water-cooled
unit option “Maximum Condenser LWT = 45degC (113 F)” is
activated. If condenser leaving water temperature is above
111.2 F (44 C), then the compressor capacity cannot increase.
If condenser leaving water temperature is above 113.0 F
(45 C), then the compressor capacity will decrease.
Override #71: Wait Until Pump Turns On Override — This
override is activated only if the water-cooled unit option “turn
cooler/condenser pump off in heating:cooling mode” is activated. When unit is not running and about to start, wait until the
pump turns on before starting compressor to avoid HP trips or
cooler freeze.
Override #77: Boostload Function Active — This override
can be present when boostload function is enabled. It is set in
the following conditions:
If fastload = BOOSTLOAD and cooler leaving water temperature > control point + 5.4° F and cooler entering water temperature > control point + 9.0° F demand limit > 99 and current
limit select = NO.
Override #80: Circuit A, 81 Circuit B: Long Time Minload
Run — If circuit runs for more than 30 minutes at minimum
load, the circuit is stopped. This is to prevent loss of oil.
b. Saturated suction temperature or saturated discharge
temperature is less than 41 F (5 C).
If any of these conditions 1, 2, 3 or 4 are met, the appropriate operating mode, 21 (Circuit A) or 22 (Circuit B) will be in
effect.
Override #41: Circuit A High Current Override
Override #42: Circuit B High Current Override — This
override attempts to avoid an overcurrent failure. The algorithm is run every 4 seconds. If the compressor current is greater than 79% of must trip amps (MTA) but less than 85% MTA
then the capacity will be held at current capacity. If the compressor current is greater than 85% MTA then capacity will be
reduced by repositioning the slide valve until the current is less
than 85% MTA (Must Trip Amps, MTA.X).
Override #44: Circuit A High Suction Superheat at Part
Load
Override #45: Circuit B High Suction Superheat at Part
Load — If the compressor of the circuit is on, the compressor
current is no more than 30% of the MTA, main EXV is more
than 90% open and the suction superheat is higher than the
superheat control point for more than 5 minutes, then the circuit will be shut down.
Override #53: Circuit A Delay for Unloading the Slide
Valve
Override #54: Circuit B Delay for Unloading the Slide
Valve — This override prevents the compressor from re-starting with locked rotor failure after being shut down due to an
alarm or power cycle. A delay of 20 minutes will elapse for all
units. The delay allows the slide valve of the compressor to
move back to its fully unloaded position. The delay is adjusted
according to the percent of the compressor running capacity
before it is shut down. If the compressor is stopped normally,
no delay will be applied. If the compressor is shut down by the
locked rotor alarm, a full delay will be applied before the compressor is allowed to re-start.
Override #59: Circuit A Low Oil Level
Override #60: Circuit B Low Oil Level — This override is
only effective when the circuit is not running. The override will
prevent the circuit from starting up with a low oil level. If this
override occurs three times, the low oil level alarm will be
tripped.
Override #62: Circuit A High Motor Temperature Override
Override #63: Circuit B High Motor Temperature Override
— This override prevents the compressor motor temperature
from rising above the high temperature limit, but still allows
the chiller to run close to the high temperature limit by unloading the compressor. If the motor temperature is greater than
214 F (101.1 C), the compressor will not load. This override
will remain active until the temperature drops below 214 F
(101.1 C). If the motor temperature is greater than 225 F
(107.2 C) for 60 seconds, the circuit capacity will decrease by
one stage. If the motor temperature is greater than 228 F
(108.9), the circuit capacity will decrease by one stage
immediately.
Override #66: Circuit A High Discharge Gas Override
Override #67: Circuit B High Discharge Gas Override —
There are two control methods possible for this override:
1. If the leaving fluid temperature exceeds the freeze setpoint (LOSP) + 5.4 °F (3 °C) and the compressor is not at
full load, the compressor capacity will be increased when
discharge gas temperature exceeds 190 F (87.8 C). Compressor capacity will be allowed to continue increasing
until discharge gas temperature falls below 175 F
(79.4 C). When the temperature is above the limit minus
2° F (1.1° C) increase in capacity will not be allowed.
This override will remain active until the discharge gas
temperature drops below the limit by –3° F (–1.7° C).
Head Pressure Control — The Main Base Board
(MBB) uses the saturated condensing temperature input from
the discharge pressure transducer to control the head pressure
control signal. The control will automatically reduce the unit
capacity as the saturated condensing temperature approaches
an upper limit. See capacity overrides #16-18. The control will
indicate through an operating mode that high ambient unloading is in effect. If the saturated condensing temperature in a circuit exceeds the calculated maximum, the circuit will be
stopped. The control will modulate the 0 to 10v head pressure
control output signal when condensing temperature is below
the minimum head pressure requirement for the compressor. In
addition, the Condenser Valve Select item under factory configuration must be set to Yes and 0-10 V signal wiring connections must be made to TB7 terminals 1 and 2.
LOW CONDENSER FLUID TEMPERATURE HEAD
PRESSURE CONTROL OPTION — Units will start and operate down to 65 F (18.3 C) entering condenser water temperature as standard. Operation with entering condenser water temperatures below 65 F (18.3 C) requires a field-supplied and installed condenser fluid control valve.
Sequence of Operation — Valve position is controlled
through a 0 to 10 vdc signal provided by the MLV/COND
board, channel 9, to maintain the head pressure set point. Unit
sizes 325-400 use a common condenser water valve output so
the MBB uses the highest saturated condensing temperature of
either circuit. As a safety feature, if the circuit is on and if the
saturated condensing temperature reaches the condensing set
point +10° F, the valve is opened to its maximum position to
avoid a high pressure alarm. The water valve is fully closed
when the circuit is OFF on unit sizes 150-300 and if both circuits are off on unit sizes 325-400.
46
5. Open discharge, liquid line, oil line, and economizer (if
equipped) service valves.
6. Fill the chiller fluid circuit with clean water (with recommended inhibitor added) or other non-corrosive fluid to
be cooled. Bleed all air out of high points of system. If
unit is exposed to temperatures below 32 F (0° C), sufficient inhibited propylene glycol or other suitable corrosion inhibited antifreeze should be added to the chiller
water and condenser water circuit to prevent possible
freeze-up. The chilled water loop must be cleaned before
the unit is connected. To set the maintenance time for
cleaning and inspecting loop strainers, go to Water Filter
Ctrl (days), W.FIL. Values for this item are counted as
days. Refer to the system pump package literature for
specific internal inspection/cleaning requirements.
7. Check tightness of all electrical connections.
8. Verify power supply phase sequence. The phase sequence
should be A-B-C for proper compressor rotation.
If the unit is configured as a heat machine, the valve will be
maintained fully open when the unit operates in heating mode
and when the condenser leaving water temperature becomes
greater than the head pressure set point.
Maximum and minimum condenser valve position is configurable. The minimum condenser valve position is very important to avoid condenser freeze risks as condenser freeze protection is ensured by the condenser pump.

PRE-START-UP
IMPORTANT: Complete the Start-Up Checklist
for 30XW Liquid Chillers at the end of this publication.
The checklist assures proper start-up of a unit, and
provides a record of unit condition, application
requirements, system information, and operation at
initial start-up.
Operating Limitations
TEMPERATURES — Unit operating temperature limits are
listed in Table 35.
Low Condenser Water Temperature Operation — For condenser entering water temperatures between 33 F (0.6 C) and
65 F (18.3 F), field installed accessory head pressure control
valve is required. Contact your Carrier representative for
details.
Do not attempt to start the chiller until the following checks
have been completed.
System Check
1. Check to ensure the unit is level per the installation
instructions.
2. Electrical power source must agree with unit nameplate.
3. Check that auxiliary components, such as the chilled fluid
and condenser fluid circulating pumps, air-handling
equipment, or any other equipment to which the chiller
supplies liquid are operational. Consult manufacturer's instructions. If the unit has field-installed accessories, be
sure all are properly installed and wired correctly. Refer
to unit wiring diagrams.
4. Open compressor suction service valves (if equipped).
CAUTION
Brine duty application (below 40 F [4.4 C] LCWT) for
chiller normally requires factory modification. Contact
your Carrier Representative for details regarding specific applications. Operation below 40 F (4.4 C) LCWT
without modification can result in compressor failure.

2. Determine maximum deviation from average voltage:
(AB) 243 – 239 = 4 v
(BC) 239 – 236 = 3 v
(AC) 239 – 238 = 1 v
Maximum deviation is 4 v.
3. Determine percent voltage imbalance:

This voltage imbalance is satisfactory as it is below the
maximum allowable of 2%.
*Temperature limit for high condensing/heat reclaim option units are
140 F (60 C).
†For sustained operation, EWT should not exceed 85 F (29.4 C).
Pulldown can be accomplished from 95 F (35 C).
**Unit requires brine modification for operation below this
temperature.
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact the local electric
utility company immediately. Do not operate unit
until imbalance condition is corrected.
VOLTAGE
Main Power Supply — Minimum and maximum acceptable
supply voltages are listed in the Installation Instructions.
Unbalanced 3-Phase Supply Voltage — Never operate a motor
where a phase imbalance between phases is greater than 2%.
To determine percent voltage imbalance:
% Voltage Imbalance = 100 x

MINIMUM FLUID LOOP VOLUME — To obtain proper
temperature control, loop fluid volume must be at least 3 gallons per ton (3.25 L per kW) of chiller nominal capacity for air
conditioning and at least 6 gallons per ton (6.5 L per kW) for
process applications. Refer to application information in Product Data literature for details.
FLOW RATE REQUIREMENTS — Standard chillers should
be applied with nominal flow rates within those listed in the
Evaporator and Condenser Flow Rates table. Higher or lower
flow rates are permissible to obtain lower or higher temperature rises. Minimum flow rates must be exceeded to assure
turbulent flow and proper heat transfer in the cooler. See
Table 36. See Fig. 27-43 for cooler pressure drop curves.
max voltage deviation from
avg voltage
average voltage
The maximum voltage deviation is the largest difference
between a voltage measurement across 2 legs and the average
across all 3 legs.
Example: Supply voltage is 240-3-60.
CAUTION
AB = 243v
BC = 236v
AC = 238v
Operation below minimum flow rate could generate alarms
and result in damage to the cooler.
Consult application data section in the Product Data
literature and job design requirements to determine flow rate
requirements for a particular installation.

Combined Leaving Chilled Water Temperature is more than
3° F (1.7° C) above the set point, then the lag chiller is started.
If the lag chiller’s water pump was not started when the machines went into occupied mode, the lag chiller water pump
will be started. The lag chiller will start with the master chiller
forcing the lag chiller demand limit value (LAG_LIM) to the
master’s demand limit value. If lead/lag capacity balance is selected, once the lag chiller has started, the master shall try to
keep the difference in capacity between lead and lag less than
20%. The master shall then be responsible for water loop capacity calculation, and will determine which chiller, the lead or
lag, will increase or decrease capacity. When the load reduces,
the lag chiller will be the first chiller to unload. To accomplish
this, the lead chiller set point is decreased by 4° F (2.2° C) until
the lag chiller unloads.
PUMP OPERATION — For parallel chiller pump operation,
the lead chiller’s water pump will be started. The lag chiller’s
water pump will be maintained off if Lag Unit Pump Control,
LAGP=0. The internal algorithm of lead chiller will control capacity of the lead chiller.
For series chiller operation, the pump is always controlled
by the master chiller.
OPERATION
Sequence of Operation — With a command to start
the chiller, the cooler and condenser pumps will start. After
verifying water flow, the control will monitor the entering and
leaving water temperatures. If the need for mechanical cooling
is determined, the control decides which circuit and compressor to start. The control will start the required compressor completely unloaded. The control will continue to load this circuit
by moving the slide valve to satisfy cooling requirements.
Once fully loaded, the control will start an additional circuit
(sizes 325-400 only) to satisfy the load as required.
For those chillers configured for heat machine duty, the control will load compressors to satisfy the required heating set
point provided there is a cooling load.
Shutdown of each circuit under normal conditions occurs in
the opposite sequence to loading. Once the circuit is fully
unloaded the compressor is shut off and the EXV will close
completely.
Dual Chiller Sequence of Operation — With a
command to start the chiller, the master chiller determines
which chiller will become the lead chiller based on the configuration of Lead Lag Select, LLBL and Lead/Lag Balance Delta, LLBD. The lead chiller is always started first and the lag
chiller is held at zero percent capacity by the master chiller
forcing the lag demand limit value to 0%. If Lead Pulldown
Time (Lead Pulldown Time, LPUL) has been configured, the

Reset is not modifying the active leaving water set point, causing SETP to be the same as CTPT.
DEMAND LIMIT ACTIVE — This mode is checked for
when the unit is ON. The mode is active when Demand Limit
(Demand Limit Type Select, DMDC) is enabled either by
DMDC=1 (Switch), DMDC=2 (4-20 mA Input), or the Night
Time Low Sound Capacity Limit (Capacity Limit, LS.LT).
The Active Demand Limit Value (Active Demand Limit
Val, LIM) will display the current demand limit according to
the programmed information and the unit’s capacity will be reduced to the amount shown or lower. The mode will terminate
when the Demand Limit command has been removed.
RAMP LOADING ACTIVE — This mode is checked for
when the unit is ON. The mode is active when Ramp Loading
(Ramp Loading Select, RL.S) is enabled and the following
conditions are met:
1. The leaving water temperature is more than 4° F (2.2° C)
from the Control Point (Control Point, CTPT), and
2. The rate of change of the leaving water temperature is
greater than the Cool Ramp Loading (Cooling Ramp
Loading, CRMP).
The control will limit the percent capacity increase until one
of the two conditions above are no longer met, then the mode
will terminate.
COOLER PUMPS ROTATION — This mode is checked for
whether the unit is ON or OFF. The mode is active when the
Cooler Pump Sequence (Cooler Pump Run Status,
PUMP=2) (2 Pumps Automatic Changeover) and the Pump
Rotation Delta Timer (Pump Auto Rotation Delay, ROT.P)
have expired.

For a fresh water system (Cooler Fluid Type, FLUD =1),
the freeze point is 34° F (1.1° C). For medium temperature
brine systems, (Cooler Fluid Type, FLUD=2), the freeze point
is Brine Freeze Set Point (Brine Freeze Setpoint, LOSP).
For criterion 1, no additional capacity will be added. For criteria 2 and 3 capacity will be decreased on the circuit. The
mode will terminate when the circuit’s SST is greater than the
freeze point minus 6° F (3.3° C) or the circuit has alarmed.
If this condition is encountered, see Possible Causes for
Alarms 56 and 57 on page 81.
HIGH DGT CIRCUIT A
HIGH DGT CIRCUIT B — The capacity of the affected
circuit may be increased to reduce circuit discharge gas
temperature.
HIGH PRES OVERRIDE CIR A
HIGH PRES OVERRIDE CIR B — This mode is checked
for when the circuit is ON. The appropriate circuit mode will
be active if the discharge pressure for the circuit, Discharge
Pressure Circuit A (Discharge Pressure, DP.A), Discharge
Pressure Circuit B (Discharge Pressure, DP.B), or Discharge
Pressure Circuit C (Discharge Pressure, DP.C), is greater than
the High Pressure Threshold (High Pressure Threshold,
HP.TH).
The capacity of the affected circuit will be reduced. Two
minutes following the capacity reduction, the circuit’s saturated
condensing temperature (SCTt+2) is calculated and stored. The
affected circuit will not be allowed to add capacity for at least 5
minutes following the capacity reduction. If after 5 minutes,
the circuit’s saturated condensing temperature is less than
SCTt+2 –3° F (1.7° C), and then if required, percent capacity
will be added. If additional capacity is required, the control will
look for other circuits to add capacity.
This mode will terminate once the circuit’s saturated condensing temperature is less than SCTt+2 –3° F (1.7° C).

for a cutaway view of the EXV. High-pressure liquid refrigerant enters valve through the top. As refrigerant passes through
the orifice, pressure drops and refrigerant changes to a 2-phase
condition (liquid and vapor). The electronic expansion valve
operates through an electronically controlled activation of a
stepper motor. The stepper motor stays in position unless power pulses initiate the two discrete sets of motor stator windings
for rotation in either direction. The direction depends on the
phase relationship of the power pulses.
The motor directly operates the spindle, which has rotating
movements that are transformed into linear motion by the
transmission in the cage assembly. The valve cone is a V-port
type which includes a positive shut-off when closed.
The large number of steps and long stroke results in very accurate control of the refrigerant flow. The stepper motor has either 4260 (main) or 2785 (economizer) steps.
MAIN EXV CONTROL — Each circuit has a thermistor located in a well in the discharge line of the compressor (DGT)
and another one located in the compressor motor cavity (SGT).
Each circuit also has discharge and suction pressure transducer.
Discharge and suction pressure as measured by the transducers
are converted to saturated temperatures.
The main control logic for the EXV uses discharge superheat to control the position of the EXV. The difference between
the temperature of the discharge gas and the saturated discharge temperature is the superheat. The EXV module controls
the position of the electronic expansion valve stepper motor to
maintain the discharge superheat set point.
The EXV control logic has several overrides, which are also
used to control the position of the EXV.
• Approach between SST and LWT
• Maximum Operating Pressure (MOP)
Approach — If the approach (pinch), which is the difference
between leaving fluid temperature and saturated suction temperature, is equal to or less than the pinch set point then the
EXV will not open any further even though discharge superheat set point is not met. Pinch set point is calculated using
suction superheat, discharge superheat and pinch offset. Pinch
offset is used to adjust calculated pinch set point do to accuracy
of transducers and thermistors.
MOP — The EXV is also used to limit cooler saturated suction
temperature to 62 F (16.7 C) for standard water-cooled units,
and 55 F (12.8 C) for high condensing units. This makes it possible for the chiller to start at higher cooler fluid temperatures
without overloading the compressor. This is commonly referred to as MOP (maximum operating pressure). If the SST is
equal to or greater than the MOP set point then the MBB will
try to control the EXV position to maintain the MOP set point.
The discharge superheat leaving the compressor is maintained between approximately 18 and 25 F (10 and 14 C), or
less. Because EXV status is communicated to the Main Base
Board (MBB) and is controlled by the EXV modules, it is possible to track the valve position. The unit is then protected
against loss of charge and a faulty valve. During initial start-up,
the EXV is fully closed. After an initialization period, valve
position is tracked by the EXV module by constantly monitoring the amount of valve movement.
ECONOMIZER EXV CONTROL — The economizer EXV
is controlled by the circuit EXV board. There is an economizer
gas temperature thermistor and economizer pressure transducer
located in the line, which runs from the economizer assembly to
the compressor. The economizer pressure is converted to saturated temperature and is used to calculate economizer superheat.
Economizer superheat equals economizer temperature minus
saturated economizer temperature. The economizer EXV only
operates during normal conditions when the capacity of the
circuit is greater than 70%. Once the capacity of the circuit is

325,375 units, connect the positive test lead to EXV-J2A terminal 5 for Circuit A and to EXV-J2B terminal 5 for Circuit B.
For 30XW175,200,250,275,300,350,400 units connect positive test lead to EXV(X)-J2A terminal 5 for EXV(X) and
EXV(X)-J2B terminal 5 for Economizer EXV(X). Using the
Service Test procedure on page 88, move the valve output under test to 100%. DO NOT short meter leads together or pin 5
to any other pin, as board damage will occur. During the next
several seconds, carefully connect the negative test lead to pins
1,2,3 and 4 in succession. Digital voltmeters will average this
signal and display approximately 6 vdc. If the output remains
at a constant voltage other than 6 vdc or shows 0 volts, remove
the connector to the valve and recheck.
Select 0% to close the valve.
NOTE: When the valve is stationary, the output from the EXV
board is 12-vdc.
See Tables 6 and 7. If a problem still exists, replace the
EXV board. If the reading is correct, the expansion valve and
EXV wiring should be checked. Check the EXV connector and
interconnecting wiring.
1. Check color-coding and wire connections. Make sure
they are connected to the correct terminals at the EXV
board and EXV plug and that the cables are not crossed.
2. Check for continuity and tight connection at all pin
terminals.
Check the resistance of the EXV motor windings. For
30XW150,325 units remove the EXV module plug EXV-J2A
for Circuit A EXV and EXV-J2B for Circuit B EXV. For
30XW175,200,250,275,300,350,400 units remove the EXV
module plug EXV(X)-J2A for main EXV and EXV(X)-J2B for
economizer EXV. Check the resistance of the two windings between pins 1 and 3 for one winding and pins 2 and 4 for the other winding. The resistance should be 52 ohms (± 5.2 ohms).
Also check pins 1-4 for any shorts to ground.
greater than 70% the MBB will start controlling the economizer
EXV to maintain economizer superheat set point, which is approximately 8° to 12° F (4.4° to 6.7° C). If the circuit capacity is
less than 70%, the economizer EXV will be closed.
The economizer EXV has one override. If the discharge gas
temperature exceeds 195 F (90.6 C) the economizer EXV will
start to open. The EXV will be controlled to maintain discharge
gas temperature at approximately 195 F (90.6 C).
If it appears that main EXV or economizer EXV is not
properly controlling circuit operation to maintain correct superheat, there are a number of checks that can be made using test
functions and initialization features built into the microprocessor control. See the Service Test section to test EXVs.
EXV TROUBLESHOOTING PROCEDURE — There are
two different economizer EXVs. Both of the economizer
EXVs have a total of 2785 steps. There are three different main
EXVs, which all have a total of 4260 steps. The EXV motor
moves at 150 steps per second. Commanding the valve to
either 0% or 100% will add an additional 160 steps to the
move, to ensure the valve is open or closed completely.
Follow the steps below to diagnose and correct EXV
problems. Check EXV motor operation first. Switch the
Enable/Off/Remote (EOR) Contact switch to the Off position.
Check the appropriate circuit EXV, Circuit A EXV % Open
(Circuit A EXV Position, EXV.A) or Circuit B EXV % Open
(Circuit B EXV Position, EXV.B). The current value of 0 will
be displayed. Increase the EXV position to select 100% valve
position. The actuator should be felt moving through the EXV.
To close the valve, select 0%. The actuator should knock when
it reaches the bottom of its stroke. See Table 40 for a list of
EXV modes and submodes.
If the valve is not working properly, continue with the following test procedure:
Check the 8-position DIP switch on the board for the proper
address (Fig. 10). Check the EXV output signals at appropriate
terminals on the EXV module. For 30XW150,185,225,260,

If re-installing the motor, be sure to use a new gasket in the
assembly. See Fig. 50. It is easier to install the motor assembly
with the piston in the fully closed position. Insert the motor into
the body of the EXV. Tighten the motor to the body to 36 ft-lb
(50 N-m) and then tighten the valve another 30 degrees.
Moisture Liquid Indicator — Clear flow of liquid refrigerant
indicates sufficient charge in system. Bubbles in the sight glass
indicate undercharged system or presence of noncondensables.
Moisture in system, measured in parts per million (ppm),
changes color of indicator. See Table 41. Change filter drier at
first sign of moisture in system.
IMPORTANT: Obtain replacement gaskets before
opening EXV. Do not re-use gaskets.
To check the physical operation of an EXV, the following
steps must be performed.
1. Close the liquid line service valve of the circuit to be
checked. Put the Enable/Off/Remote Contact (EOR)
switch in the Off position. Enter the Service Test mode
and change Service Test Enable, T.REQ from OFF to
ON. A password may be required. Switch the EOR
switch to the Enable position. Under the COMP submode, enable one of the compressors (CP.xn) for the circuit. Let compressor run until gage on suction pressure
port reads 10 psig (68.9 kPa). Turn the compressor off.
The compressor will turn off. Immediately after the compressor shuts off, manually close the actuated ball valve
(ABV). If the unit is equipped with suction service valves
and economizer service valves, close both valves. Closing the valves will minimize the amount of charge that
will have to be removed from the system after pump
down.
2. Remove any remaining refrigerant from the system low
side using proper recovering techniques. The economizer
assembly has a 1/4-in. access connection which can be
used to remove charge from the inlet of the EXVs. Turn
off the line voltage power supply to the compressors.
IMPORTANT: Unit must be in operation at least
12 hours before moisture indicator can give an accurate reading.
With unit running, indicating element must be in contact with liquid refrigerant to give true reading.

Filter Drier — Whenever moisture-liquid indicator shows
presence of moisture, replace filter drier(s). There is one filter
drier assembly on each circuit with two cores. Refer to the Carrier Standard Service Techniques Manual, Chapter 1, Refrigerants, for details on servicing filter driers.
Liquid Line Service Valve — This valve is located immediately
ahead of filter drier, and has a 1/4-in. access connection for field
charging. In combination with compressor discharge service
valve, each circuit can be pumped down into the high side for
servicing.
CAUTION
Ensure refrigerant is removed from both the inlet and outlet
of EXV assemblies. Equipment damage could result.
3. The expansion valve motor is hermetically sealed inside
the top portion of the valve. See Fig. 49. Disconnect the
EXV plug. Carefully unscrew the motor portion from the
body of the valve. The EXV operator will come out with
the motor portion of the device. Reconnect the EXV plug.
4. Enter the appropriate EXV test step under the (QUIC)
Service Test mode Locate the desired item Circuit A
EXV Position, EXV.A or Circuit B EXV Position,
EXV.B. Change the position to 100%. Observe the operation of the lead screw. See Fig. 49. The motor should be
turning, raising the operator closer to the motor. Motor
actuator movement should be smooth and uniform from
fully closed to fully open position. Select 0% and check
open to closed operation. If the valve is properly connected to the processor and receiving correct signals, yet does
not operate as described above, the sealed motor portion
of the valve should be replaced.
Installing EXV Motor
Compressor Assembly — The 30XW units utilize
screw compressors with a modulating slide valve which varies
capacity from 15% to 100% of compressor capacity for each
circuit. See Fig. 51 for a view of a typical 06T compressor.
The slide valve position is varied by opening and closing the
2 solenoid valves located on the compressor. To unload the
compressor, both solenoids are deenergized. To increase in
capacity both solenoid valves are energized together which
will cause the slide valve to slide towards the fully loaded position. To stop the loading process solenoid 2 is energized and
solenoid 1 is deenergized. This will cause the slide valve to
maintain its current position. There is no feedback for the position of the slide valve. The control utilizes compressor current
as an indicator of the slide valve position. Once the calculated
position of the slide valve reaches 100% circuit capacity, the
control will try to increase capacity again if the compressor
current continues to increase. The control will continue to load
the compressor until the compressor current no longer
increases. At that time the control will energize both solenoids
and the circuit will be considered fully loaded.
IMPORTANT: Obtain replacement gasket before
opening EXV. Do not re-use gaskets.

If unsure if there is low oil charge in the system, follow the
steps below:
1. If the unit shuts off repeatedly from a low oil level alert it
may be an indication of inadequate oil charge; however, it
could also indicate that the oil is not being recovered from
the low-side of the system.
2. Begin running the unit at full load for 11/2 hours. Use the
manual Test Mode feature of Service Test if the unit does
not normally run at full load.
NOTE: An adequate load must be available.
3. After running the unit for 11/2 hours at full load, allow the
unit to restart and run normally. If low oil alarms persist,
continue with the following steps.
4. Close the liquid line service valve and place a pressure
gage on top of the cooler. Enable the Service Test feature
and turn the Enable/Off/Remote switch to the enable position. Start the desired circuit by turning it on under the
TEST function: CP.A for compressor A, CP.B for compressor B, or CP.C for compressor C.
5. When the compressor starts successfully observe the
cooler pressure when the pressure reads 10 psig
(68.9 kPa), turn the Emergency Switch (SW2) to the OFF
position. The compressor should stop.
6. Open the liquid line service valve and allow the unit to
restart normally. If low oil level alarms persist, continue
with the following steps.
COMPRESSOR OIL SYSTEM — Each compressor/circuit
has its own oil system which includes an oil filter, oil solenoid,
check valve, oil level switch, oil pressure transducer, and an oil
shut-off valve. A typical oil system is shown in Fig. 52. See

7. If none of the previous steps were successful, the unit is
low on oil charge. Add oil to the oil separator using the
1/ in. access fitting that the discharge pressure transducer
4
is mounted to.
8. To facilitate the oil charging process, ensure that the unit
is not running when adding oil. The system is under pressure even when the unit is not running, so it is necessary
to use a suitable pump to add oil to the system.
9. Using a suitable pump, add 1/2 gal (1.9 l) of oil to the
system. Continue adding oil in 1/2 gal (1.9 l) increments
until the problem is resolved, up to a maximum of 1.5 gal
(5.7 l). If it is necessary to add factory oil charge levels to
the system contact your local Carrier representative.
Oil Filter Maintenance — Each circuit has one oil filter located externally to the compressor. Oil line pressure drop is
monitored by the control. Oil line pressure drop is calculated
by subtracting oil pressure (OP) from discharge pressure (DP).
If the oil line pressure drop exceeds 30 psi (206.8 kPa) for
5 minutes the control will generate a High Oil Filter Pressure
Drop alert. The High Oil Filter Pressure Drop alert will
not shut down the compressor, but instead indicates that the
oil filter is dirty. If oil pressure line losses exceed 50 psi
(344.7 kPa) then the control will shut down the circuit on
Maximum Oil Filter Differential Pressure Failure.

Reset is automatic as long as this is the first occurrence.
LOSS OF FLUID FLOW PROTECTION — All 30XW machines include an integral flow switch that protects the cooler
against loss of cooler flow. In addition, all models ordered for
heat reclaim duty have factory-installed condenser water sensors and an integral flow switch.
TUBE PLUGGING — A leaky tube can be plugged until
retubing can be done. The number of tubes plugged determines
how soon the cooler must be retubed. All tubes in the cooler
may be removed. Loss of unit capacity and efficiency as well
as increased pump power will result from plugging tubes.
Failed tubes should be replaced as soon as possible. Up to 10%
of the total number of tubes per pass can be plugged before
retubing is necessary. Fig. 54 shows an Elliott tube plug and a
cross-sectional view of a plug in place. See Tables 44-47 for
plug components. If the tube failure occurs in both circuits
using tube plugs will not correct the problem. Contact your
local Carrier representative for assistance.
Cooler
SUCTION SERVICE VALVE — The suction service valve
is a factory-installed option for 30XW units. It is located in the
suction outlet of the cooler. The suction service valve is bolted
between the cooler outlet and the suction flange piping. The
suction service valve shaft has a locking device located on the
shaft to lock the valve in either a fully open position or a fully
closed position. The locking device must be pulled out prior to
moving the valve handle to a fully open or a fully closed position. See Fig. 53A and 53B.
CAUTION
Use extreme care when installing plugs to prevent damage
to the tube sheet section between the holes.

Hard scale may require chemical treatment for its prevention or removal. Consult a water treatment specialist for
proper treatment procedures.
RETUBING — When retubing is required, obtain service of
qualified personnel experienced in boiler maintenance and
repair. Most standard procedures can be followed when retubing the coolers. An 8% crush is recommended when rolling
replacement tubes into the tubesheet.
Place one drop of Loctite No. 675 or equivalent on top of
tube prior to rolling. This material is intended to “wick” into the
area of the tube that is not rolled into the tube sheet, and prevent
fluid from accumulating between the tube and the tube sheet.
New tubes must also be rolled into the center tubesheet to
prevent circuit to circuit leaks.
TIGHTENING COOLER HEAD BOLTS
Preparation — When reassembling cooler heads, always
check the condition of the O-rings first. The O-ring should be
replaced if there is visible signs of deterioration, cuts or
damage. Apply a thin film of grease to the O-ring before
installation. This will aid in holding the O-ring in the groove
while the head is installed. Torque all bolts to the following
specification and in sequence:
3/ -in. Diameter Perimeter Bolts (Grade 5). . . . 200 to 225 ft-lb
4
(271 to 305 N-m)
1. Install all bolts finger tight.
2. Bolt tightening sequence is outlined in Fig. 55. Follow
the numbering or lettering sequence so that pressure is
evenly applied to O-ring.
3. Apply torque in one-third steps until required torque is
reached. Load all bolts to each one-third step before proceeding to next one-third step.
4. No less than one hour later, retighten all bolts to required
torque values.
5. After refrigerant is restored to system, check for refrigerant leaks using recommended industry practices.
6. Replace cooler insulation.
INSPECTING/CLEANING HEAT EXCHANGERS — Inspect and clean cooler tubes at the end of the first operating
season. Because these tubes have internal ridges, a rotary-type
tube cleaning system is necessary to fully clean the tubes. Tube
condition in the cooler will determine the scheduled frequency
for cleaning, and will indicate whether water treatment is
adequate in the chilled water/brine circuit. Inspect the entering
and leaving water thermistor wells for signs of corrosion or
scale. Replace the well if corroded or remove any scale if
found.
WATER TREATMENT — Untreated or improperly treated
water may result in corrosion, scaling, erosion or algae. The
services of a qualified water treatment specialist should be
obtained to develop and monitor a treatment program.
CAUTION
Water must be within design flow limits, clean and treated
to ensure proper machine performance and reduce the
potential of tubing damage due to corrosion, scaling, and
algae. Carrier assumes no responsibility for cooler damage
resulting from untreated or improperly treated water.
CHILLED WATER FLOW SWITCH — A factory-installed
flow switch is installed in the entering water nozzle for all machines. See Fig. 56 and 57. This is a thermal-dispersion flow
switch. Figure 57 shows typical installation. If nuisance trips of
the sensor are occurring, follow the steps below to correct:
When power is supplied to the device, a warm-up period is
initiated. The warm-up period may take up to 30 seconds.
When enough flow is detected, the switch contacts will close.
The switch closure does not indicate minimum flow requirements have been met for the machine.
1. Check to confirm that all strainers are clean, valves are
open and pumps are running. For the case of variable
frequency drive (VFD) controlled pumps, ensure the
minimum speed setting has not been changed.
2. Measure the pressure drop across the cooler (evaporator).
Use the cooler pressure drop curves in Fig. 27-43 to calculate the flow and compare this to system requirements.
3. If the contacts do not close with sufficient flow, then
check the wiring connection to the MBB. If the input signal is not closed, then the switch needs to be replaced.
CONDENSER WATER FLOW SWITCH AND THERMISTORS — A condenser water flow switch and entering and
leaving water thermistors are factory-installed for all heat machines and chillers with optional medium temperature brine.
See Fig. 56 and 57. This is a thermal-dispersion flow switch.

Refrigerant Circuit
LEAK TESTING — Units are shipped with complete operating charge of refrigerant R-134a or nitrogen (see Physical Data
tables supplied in the 30XW installation instructions) and
should be under sufficient pressure to conduct a leak test. If
there is no pressure in the system, introduce enough nitrogen to
search for the leak. Repair the leak using good refrigeration
practices. After leaks are repaired, system must be evacuated
and dehydrated.
REFRIGERANT CHARGE — Refer to Physical Data tables
supplied in the 30XW installation instructions. Immediately
ahead of filter drier in each circuit is a factory-installed liquid
line service valve. Each valve has a 1/4-in. access connection
for charging liquid refrigerant.
Charging with Unit Off and Evacuated — Close liquid line
service valve before charging. Weigh in charge shown on unit
nameplate. Open liquid line service valve; start unit and allow
it to run several minutes fully loaded. Check for a clear sight
glass. Be sure clear condition is liquid and not vapor.
Charging with Unit Running — If charge is to be added while
unit is operating, loop water temperatures should be near the
AHRI rating point (54/44 F evaporator; 85/95 F condenser). At
these conditions and with the circuit at full load, charge to a
clear sightglass and a liquid line temperature of 90 to 93 F (32.2
to 33.9 C).
Add 5 lb (2.3 kg) of liquid charge into the fitting located on
the tube entering the bottom of the cooler. This fitting is located
between the electronic expansion valve (EXV) and the cooler.
Allow the system to stabilize and then recheck the liquid
temperature. If needed, add additional liquid charge, 5 lb
(2.3 kg) at a time, allowing the system to stabilize between
each charge addition. Slowly add charge as the sight glass
begins to clear to avoid overcharging.

Safety Devices — The 30XW units contain many safety
devices and protection logic built into the electronic control.
Following is a description of the major safeties.
COMPRESSOR PROTECTION
Motor Overload — The compressor protection modules
(CPM) protect each compressor against overcurrent. Do not
bypass the current transducers or make any changes to the
factory-installed and configured headers. The configuration of
these headers defines the must trip amps (MTA) at which the
CPM will turn the compressors off. Determine the cause for
trouble and correct the problem before resetting the CPM. See
Appendix D for MTA settings and configuration headers.
Each CPM board also reads the status of each compressor’s
high-pressure switch. All compressors have factory-installed
high-pressure switches. See Table 48.

lowing are only recommended guidelines. Jobsite conditions
may dictate that maintenance schedule is performed more often
than recommended.
Every month:
• Check moisture indicating sight glass for possible refrigerant loss and presence of moisture.
Every 3 months:
• Check refrigerant charge.
• Check all refrigerant joints and valves for refrigerant leaks;
repair as necessary.
• Check chilled water and condenser flow switch operation.
• Check oil filter pressure drop.
Every 12 months:
• Check all electrical connections; tighten as necessary.
• Inspect all contactors and relays; replace as necessary.
• Check accuracy of thermistors; replace if greater than ±2° F
(1.2° C) variance from calibrated thermometer.
• Check accuracy of transducers; replace if greater than ±5 psi
(34.47 kPa) variance.
• Check to be sure that the proper concentration of antifreeze
is present in the chilled water and condenser loops, if
applicable.
• Verify that the chilled water loop is properly treated.
• Check refrigerant filter driers for excessive pressure drop;
replace as necessary.
• Check chilled water and condenser strainers, clean as
necessary.
• Perform Service Test to confirm operation of all components.
• Check for excessive cooler approach (Leaving Chilled
Water Temperature – Saturated Suction Temperature) which
may indicate fouling. Clean cooler vessel if necessary.
• Obtain oil analysis; change as necessary.
If the switch opens during operation, the compressor will be
shut down. The CPM will reset automatically when the switch
closes, however, a manual reset of the control is required to
restart the compressor.
COOLER PROTECTION
Low Water Temperature — Microprocessor is programmed
to shut the chiller down if the leaving fluid temperature drops
below 34 F (1.1 C) for water or more than 8 F (4.4 C) below
set point for Fluid Type = brine. When the fluid temperature
rises 6 F (3.3 C) above the leaving fluid set point, the safety
resets and the chiller restarts. Reset is automatic as long as this
is the first occurrence of the day.
IMPORTANT: If unit is installed in an area where
ambient temperatures fall below 32 F (0° C), a suitable corrosion-inhibited antifreeze solution must be
used in the chilled water and condenser water circuit.
Relief Devices — Fusible plugs are located in each cir-
cuit between the condenser and the liquid line shutoff valve.
PRESSURE RELIEF VALVES — Valves are installed in each
circuit and are located on all coolers and condensers. These
valves are designed to relieve if an abnormal pressure condition
arises. Relief valves on all coolers relieve at 220 psi (1517 kPa).
These valves should not be capped. If a valve relieves, it should
be replaced. If the valve is not replaced, it may relieve at a lower
pressure, or leak due to trapped dirt from the system which may
prevent resealing. Valves on standard condensers relieve at
220 psi (1517 kPa). Valves on high condensing and heat
machine units relieve at 300 psi (2068 kPa).
Dual pressure relief valves are mounted on the three-way
valves in some locations to allow testing and repair without
transferring the refrigerant charge. Three-way valve shafts
should be turned either fully clockwise or fully counterclockwise so only one relief valve is exposed to refrigerant pressure
at a time.
Pressure relief valves located on shells have 3/4-in. NPT
connections for relief. Some local building codes require that
relieved gases be exhausted to a specific location. This connection allows conformance to this requirement. Refer to Installation Instructions for details.
INSPECTION AND MAINTENANCE — The relief valves
on this chiller protect the system against the potentially dangerous effects of overpressure. To ensure against damage to the
equipment and possible injury to personnel, these devices must
be kept in peak operating condition.
As a minimum, the following maintenance is required:
1. At least once a year, disconnect the vent piping at the
valve outlet. Inspect the vent piping for corrosion, a restriction or blockage. If any is found, clean or replace the
affected vent piping.
2. Carefully inspect the valve body and mechanism for any
evidence of internal corrosion or rust, dirt, scale, leakage,
etc. If corrosion or foreign material is found, do not attempt to repair or recondition; replace the valve.
3. If the chiller is installed in a corrosive atmosphere or the
relief valves are vented into a corrosive atmosphere, inspect relief valves and piping at more frequent intervals.
TROUBLESHOOTING
See Table 49 for an abbreviated list of symptoms, possible
causes and possible remedies.
Alarms and Alerts — The integral control system con-
stantly monitors the unit and generates warnings when abnormal or fault conditions occur. Alarms may cause either a circuit
(Alert) or the whole machine (Alarm) to shut down. Alarms
and Alerts are assigned codes as described in Fig. 58. The
alarm/alert indicator LED on the Navigator™ module is
illuminated when any alarm or alert condition is present. If an
Alert is active, the Alarm Indicator LED will blink. If an Alarm
is active, the Alarm Indicator LED will remain on. Currently
active Alerts and Alarms can be found in (Current Alarm,
ALRM).

The controller generates two types of alarms. Automatic
reset alarms will reset without any intervention if the condition
that caused the alarm corrects itself. Manual reset alarms
require the service technician to check for the alarm cause and
reset the alarm. The following method must be followed to
reset manual alarms:
Before resetting any alarm, first determine the cause of the
alarm and correct it. To reset the alarm, set R.ALM to YES.
The alarms will be reset. Indicator light will be turned off when
switched correctly. Do not reset the chiller at random without
first investigating and correcting the cause(s) of the failure.
Each alarm is described by a three or four-digit code. The
first one or two digits indicate the alarm source and are listed in
Fig. 58. The last two digits pinpoint the problem. See Table 50.

4. Used for extra functions with the purpose of energy management such as
occupancy override switch, ice storage, setpoint reset, and demand limit.
5. Compressor capacity will be automatically determined if unit size entered
in FACTORY table matches the values in the unit compressor configuration table.
6. Total number of fans includes fans controlled by a variable speed fan. This
value will be automatically populated if unit size entered in FACTORY
table matches the values in the unit compressor configuration table.
*Not supported.
†0 = No economizer.
NOTES:
1. Table used to disable compressors for maintenance purposes. The
capacity control will consider that these compressors (once set to YES)
are failed manually (no alarm will appear).
2. Enter unit size. This item allows the controls to determine capacity of each
compressor and the total number of fans on each circuit based on a compressor arrangement array (can be viewed in table FACTORY2). It is not
necessary to enter compressor capacity and number of fans on each circuit. See the 30XW Installation Instructions for more information.
3. Number of fans controlled directly by a variable speed fan actuator using
0 to 10 vdc signal. This will enable the controls to determine the remaining
discrete fan staging outputs from the total fans on each circuit.

APPENDIX F — GLOBAL TIME SCHEDULE CONFIGURATION FOR i-Vu® DEVICE
AND CSM CONTROLLER
The following is intended to assist a Carrier technician in
configuring a 30XW chiller so either the i-Vu® 4.0 or 4.2 device, CCN Global Schedule Master, or a CSM controller can
Start and Stop the chiller. The 30XW chiller has unique table
naming convention for its Time Schedules that are different
than what is used today in CCN. The five steps outlined in the
procedures below must be followed in order to have the i-Vu
device and CCN products control the chiller.
Step 1 — Configure Chiller
1. Make sure the chiller is shut down and that the Emergency On/Off Switch (SW2) is in the Off Position and the
Enable-Off-Remote (SW1) is in the Disable position.
2. Next, UPLOAD the chiller to assure the configuration is
current.
NOTE: This must be done in both NSTV and CVIEW.
3. Change the chiller’s Time Schedule Table Name from
OCCyP0xx to OCCPC0xx. See descriptions below.
LOCAL AND NETWORK TIME SCHEDULE
DESCRIPTIONS
OCCPC01S — The i-Vu 4.2 device will write to this Time
Schedule Table.
OCC2P02S — This is for Dual Setpoint Control and MUST
be Configured for 24/7 Occupied when the i-Vu device is writing to OCCPC01S.
OCCPC65E — Used with the i-Vu device or another CCN
Global Schedule Master with Single Setpoint Control.
OCC2P02E — This will only be used with Dual Setpoint Control. This is not applicable in this application.
TIME SCHEDULE TABLE NAME CHANGE
NSTV — When using NSTV to edit a Time Schedule Name,
the process is the same for both Local (S) or Network (E) Time
Schedules.
1. Highlight the chiller, then (at the top menu bar) click on
Configure  Names…
2. When the dialog box opens, scroll down to find the four
time schedules (as seen in Fig. A for Local Schedule or
Fig. B for Network Time Schedule). Highlight the desired
Time Schedule to edit.
3. At the bottom where it says New name, double click on
OCC1P01x and rename it with OCCPC01x  click Save
 click OK.
4. Download the new configuration to the chiller.
5. Cycle power to the MBB (main base board) using SW2
emergency stop.
CVIEW — If using CVIEW to edit a Time Schedule Name,
the process is the same for both Local (S) or Network (E) Time
Schedules.
1. Highlight the chiller and click Configure  Table Names.
2. When the dialog box opens, scroll down to find the six
OCC tables.
NOTE: Only the "S" and "E" Schedules are editable.
3. Highlight the Time Schedule OCC1P01x then click Modify…
4. In the new dialog box, rename the schedule OCCPC01x
(as seen in Fig. C for Local Schedule or Fig. D for Network Time Schedule) then click OK to close this dialog
box.
5. Click Close to close the Table Names dialog box.
6. Download the new configuration to the chiller.
7. Cycle power to the MBB (main base board) using SW2
emergency stop.

APPENDIX F — GLOBAL TIME SCHEDULE CONFIGURATION FOR i-Vu® DEVICE
AND CSM CONTROLLER (cont)
Step 2 — Select Chiller Mode — There are 3 dif-
Step 4 — Set Up Chiller Switch
ferent mode selections for the chiller which are described below. In order to change the mode from the default configuration, a scrolling marquee or handheld Navigator™ device must
be used.
1. Using a Navigator™ device, select Operating Modes 
SLCT  OPER, then enter the password.
2. The screen defaults to SWITCH Mode. If using an i-Vu
device or CCN Global Scheduling, use the up arrow to
select Time Sched and then press Enter.
or
Click the up arrow and select CCN to control the chiller
using a CCN Network Command of "CHIL_S_S".
MODE DESCRIPTIONS
Switch — The chiller will be running 24/7 (no time schedule
involved). DO NOT use for the i-Vu device or CCN Global
Scheduling.
Time Sched — This mode will allow the user to configure a
local schedule and control the chiller by either Local Time
Schedule or by setpoint tables 1 or 2. This mode needs to be selected if i-Vu will be writing to either a Local (S) or Network
(E) Time Schedule.
NOTE: The i-Vu CCN 4.0 device can only write to Network
schedules.
CCN — This will be used when a CCN controller, like a CSM,
Translator, or CC will be writing to the chiller's CCN point
name CHIL_S_S for starting and stopping the equipment.
1. Set the Emergency On/Off Switch (SW2) switch to the
On Position.
2. Set the Enable-Off-Remote (SW1) switch to the Enable
position. (If Remote is used, external contacts will need
to be closed or a jumper needs to be installed on TB-5
no. 9, 10.) The chiller will run off either the Switch,
Time Schedule, or CCN Mode (see Mode Descriptions
in Step 2).
This completes the configuration decisions needed in a
30XW unit to enable i-Vu device scheduling to control the
chiller start/stop.
Step 5 — Set Up i-Vu Device Schedule
CONFIGURING THE i-Vu 4.2 DEVICE (LOCAL AND
GLOBAL SCHEDULING)
1. After chiller has been scanned into the database, check
the Schedule number. To do this, click on the Schedules
Tab  CCN Tab. The CCN Schedule Number needs to
be the same number that the user edited in Fig. A or C for
local or Fig. B or D for global (see Fig. E).
2. Next, create a Schedule by highlighting the chiller.
3. Click on Schedules  Configure  Add.
4. Then select the type of schedule from the drop down
menu.
Example: Select Normal  Weekly and the schedule
should look like Fig. F.
5. Configure the schedule.
NOTE: Refer to the i-Vu Installation and Startup manual for
more information on creating a schedule in i-Vu.
CONFIGURING THE i-Vu 4.0 DEVICE (GLOBAL
SCHEDULING)
1. After chiller has been scanned into the database, check
the Schedule number. To do this, expand the Chiller
on the left-hand navigation pane  click the on the
"Schedule" point  Properties tab  Summary Tab.
Enter CCN Global Schedule Number. It needs to be
the same number that the user edited in Fig. B or D (see
Fig G).
2. Follow Steps 2 through 5 in the Configuring the i-Vu 4.2
device (Local and Global Scheduling) section.
This completes configuring a 30XW Chiller, i-Vu device,
and CCN Network Time Schedules.
Step 3 — Select Chiller Cooling Set Point —
There are several options for controlling the Leaving Chilled
Water temperature. For the purpose of having i-Vu able to start
stop the chiller through the Time Schedule MODE the chiller's
"Cooling Set Point Select" decision needs to be configured for
SETPOINT 1 using a scrolling marquee or Navigator™
device.
1. Using a Navigator™ device, select Operating Modes 
SLCT  SP.SE, then enter the password.
2. Click the arrow up and select SETPOINT 1 then push
Enter.
