8.4.5. Anti-Freezing 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.
8.4.6. 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 continuous 2 minutes, compressor will stop and restart automatically.
•
Time Delay Safety Control is activated before the compressor restart.
s
T = Intake air temperature - Indoor heat exchanger temperature
•
This is to prevent compressor from rotate reversely when there is an instantaneous power failure.
8.4.7. Anti-Dew Formation Control
•
Purpose is to prevent dew formation on indoor unit discharge area.
•
When room temperature is constant (±1°C) the following condition occur for 30 minutes continuously, anti-dew formation will
activate:
- Indoor intake temperature is more than 24°C and less than 30°C.
- Remote Control setting temperature is less than 25°C.
- Compressor is on.
- Cooling Operation Mode.
- Indoor fan motor operate at Low fan speed or QLo.
