As you review this manual, keep in mind that:
• All field-installed wiring must conform to European
guidelines and any applicable local codes. Be sure to
satisfy proper equipment grounding requirements per
European guidelines.
• Compressor motor and unit electrical data (including
motor kW, voltage utilization range, rated load amps)
is listed on the chiller nameplate.
• All field-installed wiring must be checked for proper
terminations, and for possible shorts or grounds.
Note:
Always refer to wiring diagrams shipped with unit
submittal for specific electrical schematic and connection
information.
WARNING:
Proper field wiring and grounding required!
All field wiring MUST be performed by qualified
personnel.
Improperly installed or improperly grounded machines
can cause FIRE and ELECTROCUTION hazards
To avoid these hazards, you MUST follow requirements
in local electrical codes.
Failure to follow cade could result in death or serious
injury.
WARNING:
Hazardous voltage w/capacitors!
Disconnect all electric power, including remote
disconnects and discharge all motor start/run and
AFD (Adaptive Frequency™ Drive) capacitors before
servicing.
Follow proper lockout/tagout procedures to ensure the
power cannot be inadvertently energized.
• For variable frequency drives or others energy storing
component provided by Trane or others, refer to the
appropriate manufacturer’s literature for allowable
waiting periods for discharge of capacitors. Verify
with an appropriate voltmeter that all capacitors have
discharged.
• DC bus capacitors retain hazardous voltages after
input power has been disconnected. Follow proper
lockout/tagout procedures to ensure the power cannot
be inadvertently energized. After disconnecting
input power, wait five (5) minutes for units which are
equipped with EC fans and wait twenty (20) minutes
for units which are equipped with variable frequency
drive (0V DC) before touching any internal components
Failure to follow these instructions could result in death
or serious injury.
For additional information regarding the safe discharge
of capacitors, see “Adaptive Frequency™ Drive (AFD3)
Capacitor Discharge,” and BAS-SVX19*.

Interconnecting Wiring
Chilled Water Pump Control
NOTICE:
Equipment Damage!
If the microprocessor calls for a pump to start and
water does not flow, the evaporator may be damaged
catastrophically. It is the responsibility of the installing
contractor and/or the customer to ensure that a pump
will always be running when called upon by the chiller
controls.
An evaporator water pump output relay closes when
the chiller is given a signal to go into the Auto mode
of operation from any source. The contact is opened to
turn off the pump in the event of most machine level
diagnostics to prevent pump overheat.
The relay output is required to operate the Evaporator
Water Pump (EWP) contactor. and Heat recovery Water
Pump (HRWP) (multipipe unit) Contacts should be
compatible with 115/240 VAC control circuit. Normally,
the EWP/HRWP relay follows the AUTO mode of the
chiller. Whenever the unit has no diagnostics and is in
the AUTO mode, regardless of where the auto command
is coming from, the normally open relay is energized.
When the unit exits the AUTO mode, the relay is timed to
open in an adjustable (using TU or TD7) 0 to 30 minutes.
The non-AUTO modes, in which the pumps are stopped,
includes Reset, Stop, External Stop, Remote Display
Stop, Stopped by Tracer, Start Inhibited by Low Ambient
Temp, and Ice Making complete (if applicable).

Installer-Supplied Components / Interconnecting Wiring
If water flow is not established in 20 minutes (for normal
transition), the UC800 de-energizes the Pump relay and
generates a non-latching diagnostic. If flow returns (e.g.
someone else is controlling the pump), the diagnostic is
cleared, the Pump is re-energized, and normal control
resumed.
If evaporator water flow is lost once it had been
established, the EWP relay remains energized and a
non-latching diagnostic is generated. If flow returns,
the diagnostic is cleared and the unit returns to normal
operation. In general, when there is either a non-latching
or latching diagnostic, the Pump relay is turned off as
though there was a zero time delay. Exceptions whereby
the relay continues to be energized occur with:
• Low Water Temp. diagnostic (non-latching)
(Unless also accompanied by a Leaving Water
Temperature Sensor Diagnostic)
OR
• Loss of Water Flow diagnostic (non-latching) and the
unit is in the AUTO mode, after initially having proven
water flow.
Lead Lag Dual Pump
The running pump is changed each time the unit is
switched on.

A programmable relay concept provides for enunciation
of certain events or states of the chiller, selected from a
list of likely needs, while only using four physical output
relays, as shown in the field wiring diagram.
The four relays are provided (generally with a Quad
Relay Output LLID) as part of the Programmable Relay
Option. The relays contacts are isolated Form C (SPDT),
suitable for use with 120 VAC circuits drawing up to
2.8 amps inductive, 7.2 amps resistive, or 1/3 HP and for
240 VAC circuits drawing up to 0.5 amp resistive.
The list of events/states that can be assigned to the
programmable relays can be found in Table (…) Chiller
events/Status description. The relay will be energized
when the event/state occurs.
Table 3 - Chiller event/status descriptions
Alarm - Latching This output is true whenever there is any active latching shutdown diagnostic that targets the Unit, Circuit,
or any of the Compressors on a circuit.
Alarm - NonLatching This output is true whenever there is any active non-latching shutdown diagnostic that targets the Unit,
Circuit, or any of the Compressors on a circuit.
Alarm This output is true whenever there is any active latching or non-latching shutdown diagnostic that targets
the Unit, Circuit, or any of the Compressors on a circuit.
Alarm Ckt x This output is true whenever there is any active latching or non-latching shutdown diagnostic that targets
Circuit x, or any of the Compressors on Circuit x.
Unit Limit Mode This output is true whenever a circuit on the unit has been running in one of the limit modes continuously
for the Limit Relay debounce time. A given limit or overlapping of different limits must be in effect
continuously for the debounce time prior to the output becoming true. It will become false if no limits are
present for the debounce time.
Compressor Running The output is true whenever any compressor is running.
Circuit x Running The output is true whenever any compressor of Circuit x is running.
Ice Building This output is true when Ice Building status is active.
Maximum Capacity The output is true whenever the unit has reached maximum capacity continuously for the Max Capacity
Relay s time. The output is false when the unit is not at maximum capacity continuously for the lter time.
Evaporator Water
Freeze Avoidance
Request
This relay output is energized any time either the Low Evaporator Water Temperature – Unit Off or the
Low Evaporator Temperature Ckt x – Unit Off diagnostics are active. This relay is intended for use as an
external interlock for a eld engineered and provided solution to mitigate the freeze danger implied by
these diagnostics. Generally, this would be used in cases where operation of the evaporator water pump is
unacceptable due to the system constraints, (i.e. such as mixing unconditioned warm water with controlled
supply water as provided by other parallel chillers. The relay’s output can provide the method to close
bypass valves so the circulation becomes local to the evap and excludes the load, or can be used to defeat
the evap pump override entirely while initiating an independent source of heat / ow to the evap.
None: On Multi-pipe units, it mandatory to connect Evaporator Freeze avoidance relay output to pump or valve
that rapidly establish evaporator water ow even if unit is in AUTO mode.
This selection is desirable to provide an easy way for a customer to defeat the effect of the relay, if it has
already been wired. For instance, if the relay was normally programmed as an “alarm” relay, and was
wired to a claxon, it may be desirable to temporarily defeat the feature without changing wiring.
Service request (for
Unit, Compressor(s)
or water pump):
This relay will be energized when at least one Maintenance alert condition (refer to Service required
message specication) occurs, as long as at least one of associated informational diagnostic(s) will be
active.
Warning
The output is true whenever there is any active warning diagnostic that is associated with the Unit, Circuit, or any of
the compressors on a circuit.

Low Voltage Wiring / Ice Making (Optional)
Low Voltage Wiring
The remote devices described below require low voltage
wiring. All wiring to and from these remote input devices
to the Control Panel must be made with shielded,
twisted pair conductors. Be sure to ground the shielding
only at the panel.
Important:
To prevent control malfunctions, do not run low voltage
wiring (<30 V) in conduit with conductors carrying more
than 30 volts.
Emergency Stop
UC800 provides auxiliary control for a customer
specified/installed latching trip out. When customer
furnished remote contact 6S2, the chiller will run
normally when the contact is closed. When the contact
opens, the unit will stop and a manually resettable
diagnostic is generated. This condition requires manual
reset at the chiller switch on the front of the control
panel.
This customer-furnished contact must be compatible
with 24 VDC, 12 mA resistive load.
External Auto/Stop
If the unit requires external Auto/Stop function, the
installer must provide remote contact 6S1.
The chiller will run normally when the contact is closed.
When contact opens, the compressor(s), if operating, will
go to the RUN: UNLOAD operating mode and cycle off.
Unit operation will be inhibited. Closure of the contact
will permit the unit to return to normal operation.
Field-supplied contacts for all low voltage connections
must be compatible with dry circuit 24 VDC for a 12mA
resistive load. Refer to the field diagrams that are
shipped with the unit.
Ice Making (Optional)
When the Ice Making Command is removed (i.e. all
the installed Ice Making inputs are set to “auto”), the
compressors shall be stopped after the run unload
period (if not already stopped due to Ice Making
Complete). The chiller shall return to normal Auto mode
of operation, and allowed to restart only after enforcing
a 2 minute delay called the “Ice to Normal Transition
time”. During this inhibit, the Evaporator water flow
request shall be commanded on. After the delay, the
chiller can restart again per the differential to start and
the normal Chilled Water Setpoint (or Hot Water Setpoint
– if in Heating Mode). The Ice To Normal Transition
inhibit shall be annunciated as a Chiller Submode and a
countdown timer showing the remaining time left shall
be displayed.
Ice Making Configuration:
Ice Making is configured through TU, and there shall be
two installation options:
1. Not Installed
2. Installed with Hardware
Ice Making: Not Installed
If the Ice Building Configuration item is set to ‘Not
Installed’, the application will not build the Ice Making
objects, and will require none of the Ice Making specific
LLIDS.
Ice Making: Installed with Hardware
If the Ice Making Configuration item is set to ‘Installed’,
the application will require the following LLIDs:
• External Ice Making Input (Dual Low Voltage Binary
Input)
Ice Making Setpoints:
After Ice Making is configured, there shall be three Ice
Making Settings or Setpoints:
1. Ice Making Command
2. Ice Making Enable/Disable
3. Ice Making Termination Setpoint
The ice making setpoints can all be manipulated through
TU. Some of the Setpoints can be manipulated with User
Interface on the Display, the External Hardware Interface
BAS (if a BAS is installed).
The setpoints associated with ice making are explained
in more detail below.
Ice Making Command
This is the command to enter ice making. This setting is
defined as an Auto/On settings. Setting this to On will
command the application into ice building if ice building
is enabled and the Chiller is in the “Auto” command
mode. Setting the Ice Making command to Auto will
command the application to follow the next priority
functional mode.
Regardless of the setting of the Setpoint Source (see
setpoint arbitration.doc) any of the following 4 signals
can combine to comprise the Ice Building Command
(assuming they are each installed).
Contact closure input for External Ice Making Command
Front Panel Ice Making Command (also writable from
TU Lontalk Communicated Ice Making Command (LCI-C,
BACnet, Modbus)
Time of Day scheduler
All ice making signals have to be turned to “auto” to be
able to turn back Ice Making Command to “Auto” mode.
The overall Ice Making Command, must be toggled from
“Ice Making”, to “Auto” to “Ice Making” again, before
Ice Making can be entered a second time.
Ice Making Enable/Disable setting
This setting does not start or stop ice building. This is
the command to enable or disable the entire ice building
feature. It can only be set through the Display or TU.
The Ice Making Command starts and stops ice building.
Ice Making Termination setpoint
This setpoint controls when Ice Making is complete. If
the Entering Water Temperature decreases below this
setpoint with no deadband Ice Making will be deemed
complete. This setpoint has a range of –6.7°C (20°F) to
0°C (32°F) with a default of -2.8°C (27°F).

Ice Making (Optional)
Evaporator Application defines controls settings: if ICE
is selected, Ice making is enabled. Specific hardware is
required for ice making command input and ice making
status relay output.
UC800 provides auxiliary control thanks to Ice Making
Status Relay. The normally open contact will be closed
when ice making is in progress and open when ice
making has been normally terminated either through
Ice Termination setpoint being reached or removal of
the Ice Making command. This relay inform customer
equipment with chiller mode changes from “ice making”
to “ice complete”
When contact is provided, the chiller will run normally
when the contact is open.
UC800 will accept either an isolated contact closure
(External Ice Making command) or a Remote
Communicated input (Tracer) to initiate and command
the Ice Making mode.
UC800 also provides a “Front Panel Ice Termination
Setpoint”, settable through Tracer™ TU, and adjustable
from 20 to 31°F (-6.7 to -0.5°C) in at least 1°F (1°C)
increments.
Note:
When the unit runs in Ice Making mode, and the
evaporator entering water temperature drops below the
ice termination setpoint, the chiller terminates the Ice
Making mode and changes to the Ice Making Complete
Mode.
NOTICE:
Equipment Damage!
Freeze inhibitor must be adequate for leaving water
temperature unless system components can be
damaged.
Tracer™ TU must also be used to enable or disable
Ice Machine Control. This setting does not prevent
the Tracer from commanding Ice Making mode. Upon
contact closure, the UC800 will initiate an ice making
mode, in which the unit runs fully loaded at all times. Ice
making shall be terminated either by opening the contact
or based on the entering evaporator water temperature.
UC800 will not permit the ice making mode to be entered
again until the unit has been switched out of ice making
mode.
If, while in ice making mode, the unit gets down to the
freeze stat setting (water or refrigerant), the unit will
shut down on a manually resettable diagnostic, just as in
normal operation.
Connect leads to the proper terminals. Refer to the field
diagrams which are shipped with the unit. This customer
supplied contacts must be compatible with 24 VDC,
12 mA resistive load.

External setpoints & capacity outputs (Optional)
External Chilled Water Setpoint (ECWS)
The UC800 provides inputs that accept either 4-20 mA
or 2-10 VDC signals to set the external chilled water
setpoint (ECWS). This is not a reset function. The input
defines the setpoint. This input is primarily used with
generic BAS (building automation systems).
Functional Description
When the unit is in cooling mode, the external water
setpoint (EWS) will correspond to the chilled water
setpoint. The external chilled water setpoint shall have a
configurable minimum and maximum.
2-10 VDC and 4-20 mA shall each correspond to an EWS
range with a configurable minimum and maximum EWS.
The following relationships exist:
Input Signal External Water Setpoint
< 1 VDC Invalid
1 VDC to 2 VDC min
2 VDC to 10 VDC min + (max – min) *
(Signal – 2) / 8
10 VDC to 11 VDC max
> 11 VDC Invalid
< 2 mA Invalid
2 mA to 4 mA min
4 mA to 20 mA min + (max – min) *
(Signal – 4) / 16
20 mA to 22 mA max
> 22 mA Invalid
If the ECWS input develops an open or short, the LLID
will report either a very high or very low value back to
the main processor. This will generate an informational
diagnostic and the unit will default to using the Front
Panel (TD7) Chilled Water Setpoint.
Tracer TU Service Tool is used to set the input signal
type from the factory default of 2-10 VDC to that of 4-20
mA. Tracer TU is also used to install or remove, enable
or disable the External Chilled Water Setpoint.
