7314. Protection Control14.1 Restart Control (Time Delay Safety Control)• When the thermo-off temperature (temperature which compressor stops to operate) is reach during:-o Cooling operation – the compressor stops for 3 minutes (minimum) before resume operation.o 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 themoment operation stop, although the unit is turn on again within the period.• This phenomenon is to balance the pressure inside the refrigerant cycle.14.2 7 Minutes Time Save Control• The compressor will start automatically if it has stopped for 7 minutes and the intake air temperature fallsbetween 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.14.3 60 Seconds Forced Operation• Once the air conditioner is turned on, the compressor will not stop within 60 seconds in a normal operationalthough the intake air temperature has reached the thermo-off temperature. However, forced stop by pressingthe OFF/ON operation button at the remote control is permitted.• The reason for the compressor to force operate at the minimum 60 seconds is to allow the refrigerant oil run in afull cycle and return back to the outdoor unit.14.4 Starting Current Control• When the compressor, outdoor fan motor and indoor fan motor are simultaneously started, the indoor fan motorwill start to operate at 1.6 seconds later.• The reason of the difference is to reduce the starting current flow.
