4313 Protection Operation13.1. 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 operationstop, although the unit is turn on again within the period.• This phenomenon is to balance the pressure inside the refrigerant cycle.13.2. 7 Minutes Time Save Control• The compressor will start automatically if it has stopped for 7 minutes and the intake air temperature falls between thecompressor ON temperature and compressor OFF temperature during the period.• This phenomenon is to reduce the built up humidity inside a room.13.3. 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 airtemperature has reached the thermo-off temperature. However, force stop by pressing the OFF/ON operation button at theremote 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 returnback to the outdoor unit.13.4. Starting current Control• When the compressor, outdoor fan motor and indoor fan motor are simultaneously started, the indoor fan motor will start tooperate at 1.6 second later.• The reason of the difference is to reduce the starting current flow.
