8.5.4. 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.
8.5.5. 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 (cooling mode) or less for continuous 2 minutes, compressor will stop and restart automatically.
•
Time Delay Safety Control is activated before the compressor restart.
▲
T = Intake air temperature - Indoor heat exchanger temperature
•
This is to prevent compressor from rotate reversely when there is an instantaneous power failure.
8.5.6. 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.
8.5.7. Anti-Dew Formation Control
•
Purpose is to prevent dew formation on indoor unit air discharge area.
•
When room temperature is constant (±1°C) the following conditions occur for 30 minutes continuously, anti-dew formation will
activate:
−
Remote Control setting temperature is less than 25°C.
−
Compressor is on.
−
Cooling operation mode.
−
Indoor Fan motor operate at Low fan speed (CLo, Lo- or QLo).
•
This control is cancelled immediately when above condition is changed, or Powerful button is pressed.
•
Anti-Dew formation is control by:
1. CLo fan is changed to HLo fan.
2. QLo fan is changed to HLo fan.
