8.5. Operation Control
8.5.1. Restart Control (Time Delay Safety Control)
• When the thermo-off temperature (temperature which compressor stops to operate) is reached during:-
− Cooling/Heating operation - the compressor stops for 3 minutes (minimum) before resume operation.
− Soft Dry operation - the compressor stops for 6 minutes (minimum) before resume operation.
• If the operation is stopped by the remote control, the compressor will not turn on within 3 minutes from the moment operation
stop, although the unit is turn on again within the period.
• This phenomenon is to balance the pressure inside the refrigerant cycle.
8.5.2. Compressor Reverse Rotation Protection Control
• If the compressor is operating continuously for 5 minutes or longer and the temperature difference between intake air and
indoor heat exchanger is 2.5°C (cooling mode)/5°C (heating mode) or less for continuous 2 minutes, compressor will stop and
restart automatically.
• Time Delay Safety Control is activated before the compressor restart.
T = Intake air temperature - Indoor heat exchanger temperature
• This is to prevent compressor from rotate reversely when there is an instantaneous power failure.
