Panasonic CS-A7DKD [23/88] Operation control

• The operation mode judging temperature and standard setting temperature can be increased by 2°C permanently, by open the

circuit of JX1 at indoor electronic controller.

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.

s T = Intake air temperature - Indoor heat exchanger temperature

• This is to prevent compressor from rotate reversely when there is an instantaneous power failure.
