OPERATIONS MANUAL
2. Press the “UP” button until “/C1” appears in the display.
Release the “UP” button.
3. Press and release the “SET” button. The current value of the
offset will appear in the display.
4. Press the “UP” button to increase or the “DOWN” button to
decrease the offset value.
5. Press and HOLD the “SET” button for 5 seconds to confirm
and save the new value. When complete, the current tem-
perature will be displayed. RELEASE the “SET” button.
EXAMPLE: If a sensing device in the cabinet reads 38°F and the
control display shows 41°F, follow steps above and decrease the
current offset by 3°F. If the current offset was 0, change to -3.
HOW TO CHANGE THE SET-POINT
Refrigerators are factory set to maintain an average temperature
of 38°F. Freezers are factory set to maintain an average tempera-
ture of 0°F. To change set-point:
1. Press and HOLD the “SET” button until the current set-point
begins flashing. Release the “SET” button.
2. Press the “UP” or “DOWN” button to adjust to the new set-
point value.
3. Press and release the “SET” button to lock in the new set-
point. The control will now resume normal operation with
the new set-point.
ANTI-CONDENSATE CONTROL
1. To see the current state of the aux heaters (anti-conden-
sate), press and HOLD the “AUX HTR” button for 1 second.
RELEASE the “AUX HTR” button. The display will show the
current state of the heater (“ON” or “OFF”) when the button
is pressed.
2. To change the current state of the AUX Heaters, press and
HOLD the “AUX HTR” button. The display will show the cur-
rent state of heater operation. After 5 seconds, the heater
will switch to the opposite state and the display will return
to displaying the cabinet temperature. RELEASE the button.
The control has a built in energy saving feature for the anti-
condensate (AUX) heaters. When set to ON, the heaters will
automatically energize when conditions require additional heat,
to eliminate condensation. The “AUX” icon on the display will
illuminate when the AUX heaters are energized. To maximize
energy savings, the AUX heaters can be set to OFF, as described
above. In this state, the heaters will never energize. If you ever
notice moisture accumulating on the face of your cabinet, adjust
the AUX control to ON. This will energize the heaters and warm
the face of the cabinet, eliminating any condensation that may
accumulate.
HOW TO INITIATE A MANUAL DEFROST
This is used when a one-time additional defrost may be neces-
sary to clear accumulated ice from the evaporator coil.
1. Press and HOLD the defrost button for 5 seconds.
2. After 5 seconds, the defrost icon will illuminate. RELEASE
the defrost button.
IMPORTANT NOTE: During manual defrost, be sure to
connect your floor drain to a drainage destination.
HOW TO CHANGE THE DEFROST INTERVAL
This is used to increase or decrease the frequency of defrosts.
If the interval is set at “8”, a defrost will occur every 8 hours. If
you need more defrosts, lower this value.
1. Press and HOLD the “SET” button until “PS” appears flash-
ing in the display. Release the “SET” button.
2. Press the “UP” button until “DI” (defrost interval) appears
in the display. Release the “UP” button.
3. Press and RELEASE the “SET” button. The current defrost
interval will appear in the display.
4. Press the “UP” or “DOWN” button to adjust to the new
defrost interval.
5. Press and HOLD the “SET” button to lock in this new value.
When the display returns back to cabinet temperature,
release the “SET” button.
NOTE: Defrost cycles are time initiated and temperature
terminated with a maximum time cut-off.
HIGH AND LOW TEMPERATURE ALARMS
The controller has high and low alarm set-points. These values
can be modified per the end user requirements. There is a pre-
programmed time delay for the alarm to activate to eliminate
nuisance alarms. To change the alarm threshold values:

ing in the display. Release the “SET” button.

setting will be shown.
4. Press the “UP” or “DOWN” button to get the desired alarm
set-point.
