12.5.5. 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.
V T = Intake air temperature - Indoor heat exchanger temperature
• This is to prevent compressor from rotate reversely when there is an instantaneous power failure.
12.5.6. 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.
12.5.7. Dew Prevention Control
• Purpose is to prevent dew formation on indoor unit air discharge area.
• The following conditions occur for 30 minutes continuously, dew prevention control 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.
• Dew prevention is control by:
1. Lo fan speed.
Lo fan is changed to Lo+ fan
