HOW TO SWITCH THE CONTROLLER OFF/ON
The controller can be switched OFF. The display will still be
active but all systems operated by the control will be OFF.
1. To turn the controller OFF, press and HOLD “POWER” but-
ton for 5 seconds. When in the OFF mode, “OFF” will alter-
nate in the display with the current appliance temperature.
2. To turn the controller back “ON”, press and HOLD “POWER”
button for 5 seconds. The controller will resume normal
operation.
ANTI-CONDENSATE CONTROL (ON)
1. To see the current state of the aux heaters (anti-conden-
sate), press and HOLD “AUX HTR” button for 1 second.
RELEASE “AUX HTR” button. The display will show the cur-
rent state of the heater when the button is pressed.
2. To change the current state of the AUX Heaters, press and
HOLD “AUX HTR” button. The display will show the current
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 AUX (anti-
condensate) heaters. When in the ON position, the AUX icon
may not illuminate indicating the AUX heaters are not currently
energized. The control will automatically energize the AUX heat-
ers when the conditions require these heaters to be activated.
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 “UP” and “DOWN” buttons simultaneously
for 5 seconds.
2. After 5 seconds, the defrost icon will illuminate. RELEASE
“UP” and “DOWN” buttons.
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 “SET” button until “PS” appears flashing
in the display. Release “SET” button.
2. Press “UP” button until “DI” (defrost interval) appears in
the display. Release “UP” button.
3. Press and RELEASE “SET” button. The current defrost inter-
val will appear in the display.
4. Press “UP” or “DOWN” button to adjust to the new defrost
interval.
5. Press and HOLD “SET” button to lock in this new value.
When the display returns back to cabinet temperature,
release “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:
1. Press and HOLD “SET” button until “PS” appears flashing
in the display. Release “SET” button.
2. Press “UP” button until “AL” (Low Alarm Setting) or “AH”
(High Alarm Setting) appears in the display. Release “UP”
button.
3. Press and RELEASE “SET” button. The current alarm setting
will be shown.
4. Press “UP” or “DOWN” button to get the desired alarm
set-point.
5. Press and HOLD “SET” button for 5 seconds to confirm and
save the new value. When complete, the current tempera-
ture will be displayed. Release “SET” button.
NOTE: When in an alarm condition, the display will alter-
nate between the cabinet temperature and alarm code.
“AL” when in a low temperature alarm condition and “AH”
when in a high temperature alarm condition. The control
will also beep and the alarm icon will activate when in an
alarm condition. To silence the alarm beeper for the active
alarm just press and release the “SET/MUTE” button.
ELECTRONIC CONTROL ERROR CODES
If there is a regulation probe error, the display will just show
alarm code “E0” and not flash the cabinet temperature. If there
is a probe error, you must contact your service provider
immediately.
Alarm Code Alarm Description Notes
E0 Regulation Probe Error Located in return air stream
E1 Evaporator Probe Error Located in evaporator coil
E2 Ambient Probe Error Located on side of electrical box
LO Low Temperature Alarm Reference “AL” parameter
HI High Temperature Alarm Reference “AH” parameter
• If there is an error code “E0”, the control will operate the
appliance in a preprogrammed ON/OFF cycle based on time,
not temperature.
• If there is an error code “E1”, the control will still go into a
defrost but will terminate on time, not temperature.
• If there is an error code “E2”, the aux heaters will not oper-
ate.
