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.
