– During Anti-dew condensation prevention, Airflow Direction Manual control angle change from 0°, 11°, 22°, 33°, 44° to
14°, 18°, 22°, 26°, 30° under Cooling and Soft Dry operation mode.
(For 11.5.8 to 11.5.14 information applies only to Heating Operation)
12.5.8. Restart Control (Time Delay Safety Control)
• When the thermo-off temperature (temperature which compressor stops to operate) is reached during:-
- Heating 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.
12.5.9. Compressor Reverse Rotation Protection Control
• If the compressor is operating continuously for 5 minutes or longer and the temperature difference between indoor heat
exchanger and intake air is 5°C or less for continuous 2 minutes, compressor will stop and restart automatically.
• Time Delay Safety Control is activated before the compressor restart.
▲ T = Indoor heat exchanger temperature - Intake air temperature
• This is to prevent compressor from rotate reversely when there is an instantaneous power failure.
12.5.10. Overload Protection Control
• Outdoor Fan Control
- If the temperature of the Outdoor Heat Exchanger less than -3°C, Outdoor Fan is ON. The Outdoor Fan stop, when Outdoor
Heat Exchanger temperature is Tb or more according to Outdoor Air Temperature region as table below:
The Outdoor Fan restarts when the indoor heat exchanger temperature falls to 49°C.
During starting of Heating mode and after deice, Outdoor Fan ON for 90 sec. (Hi).
• Compressor High Pressure Control
- If the indoor heat exchanger becomes 68°C or more, the compressor will stop and restart automatically.
- Time Delay Safety Control is activated before the compressor restart.
