Ice Making (Optional)
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).
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.
