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 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.
•
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.
•
This control is cancelled immediately when above condition is changed.
•
Anti-Dew formation is control by:
1. Lo fan speed
Lo fan is changed to Lo+ fan
