12.5. Operation Control
(For 12.5.1 to 12.5.7 information applies only to Cooling and Soft Dry Operation)
12.5.1.
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 operation
stop, although the unit is turn on again within the period.
• This phenomenon is to balance the pressure inside the refrigerant cycle.
12.5.2.
60 Seconds Forced Operation
• Once the air conditioner is turned on, the compresor 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.
12.5.3.
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.
12.5.4.
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.
