    Functions of compressor

    Under electric-heating defrost mode:
    Start-up condition: Relay of compressor connects when meet both a) and b) or both a) and c).
    Compressor delay time exceeds the set delay time.
    Enforced refrigeration starts when Room temp, is higher than Set temp.
    Under non-defrost mode, Room temp, is higher than Set temp. + Return difference. Stop condition: Relay of compressor disconnects when meet any of the ff. conditions. O Room temp, is lower than Set temp.
    O At start-up of defrost.
    O Enforced refrigeration stops.
    Under thermal defrost mode:
    Start-up condition: Relay of compressor connects when meet both a) and b) or both a) and c) or both a) and d).
    Compressor delay time exceeds the set delay time.
    Under non-defrost mode, Room temp, is higher than Set temp. + Return difference.
    Enforced refrigeration starts when Room temp, is higher than Set temp.
    When defrost.
    Stop condition: Relay of compressor disconnects when meet any of the ff. conditions.
    Room temp, is lower than Set temp.
    O At end of defrost.
    O Enforced refrigeration stops and not to start immediate defrost.
    Defrost function:
    Relay of defrost connects when meet the ff. conditions:
