8.4. Operation Control
8.4.1. 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.
8.4.2. 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.
8.4.3. 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.
8.4.4. Starting Current Control
•
When the compressor, outdoor fan motor and indoor fan motor are simultaneously started, the indoor fan motor will start to
operate at 1.6 second later.
•
The reason of the difference is to reduce the starting current flow.
