Your commercial refrigerator is manufactured with an electronic thermostat to control various functions of
your unit, such as the temperature, defrost cycles, fan operation, alarms, etc. The electronic thermostat
has been programmed at the factory and its keyboard was locked to prevent tampering.
Reading the LEDs
Each LED function is described in the following table:
To unlock the keyboard
Press and hold the
keys for more than three seconds until the “PON” message is displayed.
The Set point parameter is the temperature at which the compressor cuts out.
To see the Set point
Push and immediately release the SET key and the display will show the Set point value.
To change the Set point
1.
Push and hold the SET key for more than 2 seconds. The value of the Set point will be displayed
and the LED will start blinking.
2.
Use the
keys within 15 seconds of pressing the SET key to change the Set value.
3.

Cut In temperature is the Set point value plus the Differential value. The Differential value is
programmed at the factory to protect the compressor from short cycling.
