14.15 Restart Control (Time Delay Safety Control)
•
When the thermo-off temperature (temperature which compressor stops to operate) is reached during:-
o
Cooling / Heating 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.
14.16 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.
14.17 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.
14.18 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.
14.19 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.
