(For 13.15 to 13.21 information applies only to Cooling and Soft Dry Operation)
13.15 Restart Control (Time Delay Safety Control)
• When the thermo-off temperature (temperature which compressor stops to operate) is reached 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.
13.16 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 and compressor OFF temperature during the period.
• This phenomenon is to reduce the built up humidity inside a room.
13.17 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.
13.18 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.
13.19 Freeze Prevention Control
• If the temperature of the indoor heat exchanger falls below 2°C continuously for 4 minutes or more, the
compressor turns off.
The fan speed setting remains the same.
• This phenomenon is to protect the indoor heat exchanger from freezing and to prevent higher volume of
refrigerant in liquid form returning to the compressor.
• Compressor will restart again when the indoor heat exchanger temperature rises to 10°C (Recovery).
• Restart control (Time Delay Safety Control) will be applied in this Control if the recovery time is too short.
