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 2 minutes, compressor will stop and
restart automatically. / (Time Delay Safety Control is valid)
T = Intake air temperature - Indoor heat exchanger temperature /
This is to protect reverse rotation of the compressor when there is
a instantaneous power failure.
Anti-Dew Formation Control
- Purpose is to prevent dew formation on indoor unit air discharge
area.
- When the following conditions accur for 30 minutes continuously,
anti-dew formation is controlled by indoor fan speed shift to low
(CLo to HLo):
- Indoor intake air 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.
- This control is cancelled immediately when above condition is
changed.
