Adjusting the set point
The set point is what determines how cold the display case will hold food and beverage. To adjust the
set point press the
“
” button.
Then press
“ ” button to increase the set point number (colder)
or
press the
“ ” button to decrease the set point number (warmer).
There are nine (9) available set
points numbers, the higher the number of the set point, the colder the display case will run, with
setting “9” being the coldest and setting “1” being the warmest. Once you have chosen your desired
setting press the
“
” button again to confirm your choice. The control cutout temperature for the
selected setpoint will briefly be displayed if the setpoint was changed.
Entering manual defrost mode
The control is programmed to automatically initiate a defrost by two different methods, involving time
and temperature, as outlined in the “Defrost Cycle” section (Pg.15) of “ELECTRONIC CONTROL
FUNCTIONALITY
.” While it is uncommon that the automatic defrost cycles would insufficiently
defrost the case, a Manual Defrost mode is available if this situation arises.
Note: The control will not allow the initiation of a manual defrost within 30 minutes of completion of
another defrost cycle, manual or automatic.
To initiate a manual defrost press and hold the
“ ” button approx. three seconds. The defrost is
initiated when the defrost mode indicator illuminates on the display. The control display will then
return to reading the probe temperature. When the defrost mode indicator turns off the defrost is
complete and the compressor will turn back on automatically and the compressor and condenser fan
indicator will be shown ( & ).
Control Alarms
It is possible for error codes to be displayed on the control screen. In the event of a malfunction an alarm will
sound and the alarm indicator will be displayed. An error code or codes will flash intermittently on the
display. If there are multiple codes, the display will continuously cycle through them.
Mute: You may mute the alarm by pressing any button. The red alarm symbol and all error codes will still be
displayed. When the fault is remedied, the control will return to normal operation and will automatically clear
the codes from the display.

•
Check to ensure probe wires and quick disconnect are secure
in control.
•
Check probe resistance to table below. If 0 resistance is
present, check wiring insulation. If infinite resistance is
present, check for breaks in wiring (meter will likely read
overload or very high in the mega-ohm range).
•
Ensure that probes are wired per the wiring diagram provided.
Replace probe if other remedies fail, or if probe resistance
deviates from “Table 3” below.
