12. Protection Control
12.1 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.

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.
12.2 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.
12.3 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, 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.
12.4 Freeze Preventive 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.
