13. Protection Control
13.1 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 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.
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 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.
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 air temperature has reached the thermo-off temperature. However, forced stop by pressing
the 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 a
full cycle and return back 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 to operate at 1.6 seconds later.
• The reason of the difference is to reduce the starting current flow.
