•
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.
