13.5 Freeze Prevention Control
To protect indoor heat exchanger from freezing and to prevent higher volume of refrigerant in liquid form return to
compressor.
This control will activate when temperature of indoor heat exchanger falls below 2°C continuously for more than 4
minutes and compressor turn off.

The current fan speed will change to freeze prevention speed after 70 seconds compressor on. The fan speed
will be increased according to the indoor pipe temperature as below figure: (Applicable for C9KKV and C12KKV
ONLY)
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.
13.6 Compressor Reverse Rotation Protection Control
If the compressor is operating continuously for 5 minutes or longer and the temperature difference between
intake air and indoor heat exchanger is 2.5°C or less for continuously 2 minutes, compressor will stop and restart
automatically.
Time Delay Safety Control is activated before the compressor restart.
This is to prevent compressor from rotate reversely when there is an instantaneous power failure.
If this condition happens continuously for 5 times within 50 minutes, unit will turn OFF with TIMER LED blinks.
The 5 Times counter can be reset when either one of the following condition happen:
o
Unit is OFF by remote control or AUTO OFF/ON button.
o
Indoor intake temperature – Indoor piping temperature > 5°C for one minute or more.
o
Operation mode change.
The unit could be ON by pressing OFF/ON button at remote control but the TIMER LED will continue blinking.
TIMER LED blinking will be reset if:
o
Indoor intake temperature – Indoor piping temperature > 5°C for one minute or more.
o
Power supply reset.
