Setting and Indication of the Control PCB
This refrigeration unit is equipped with the function of setting a variety of compressor operation
modes by the switch on the control PCB.
Operating condition of the compressor can be checked by the LED on the control PCB.
In particular, when any anomalies occur in the refrigeration unit, an alarm LED (red) lights up or
blinks, and the cause of anomaly is displayed digitally by an alarm code.
