3313.5. Compressor Reverse Rotation Protection Control• If the compressor is operating continuously for 5 minutes or longer and the temperature difference between intake air and indoorheat 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.13.6. Starting Current Control• When the compressor, outdoor fan motor and indoor fan motor are simultaneously started, the indoor fan motor will start tooperate at 1.6 second later.• The reason of the difference is to reduce the starting current flow.13.7. 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(For 11.5.8 to 11.5.14 information applies only to Heating Operation)13.8. Restart Control (Time Delay Safety Control)• When the thermo-off temperature (temperature which compressor stops to operate) is reached during:-- Heating operation - the compressor stops for 3 minutes (minimum) before resume operation.• If the operation is stopped by the remote control, the compressor will not turn on within 3 minutes from the moment operationstop, although the unit is turn on again within the period.• This phenomenon is to balance the pressure inside the refrigerant cycle.13.9. Compressor Reverse Rotation Protection Control• If the compressor is operating continuously for 5 minutes or longer and the temperature difference between indoor heatexchanger and intake air is 5°C (heating mode) or less for continuous 2 minutes, compressor will stop and restart automatically.• Time Delay Safety Control is activated before the compressor restart. T = Indoor heat exchanger temperature - Intake air temperature• This is to prevent compressor from rotate reversely when there is an instantaneous power failure.
