Operation Control

(For 8.5.1 to 8.5.7 information applies only to Cooling and Soft Dry Operation)
8.5.1. Restart Control (Time Delay Safety Control)
• When the thermo-off temperature (temperature which compressor stops to operate) is reached during:-
− Cooling 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. 60 Seconds Forced Operation
• Once the air conditioner is turned on, the compressor will not stop within 60 seconds in a normal operation although the intake
air temperature has reached the thermo-off temperature. However, force stop by pressing the OFF/ON operation button at the
remote control is permitted.
• The reason for the compressor to force operate at minimum 60 seconds is to allow the refrigerant oil run in a full cycle and
return back to the outdoor unit.
8.5.3. 7 Minutes Time Save Control
• The compressor will start automatically if it has stopped for 7 minutes and the intake air temperature falls between the
compressor ON temperature (A) and compressor OFF temperature (B) during the period.
• This phenomenon is to reduce the built up humidity inside a room.
