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.
