3112.4.5. 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 or less for continuous 2 minutes, compressor will stop and restart automatically.• Time Delay Safety Control is activated before the compressor restart.• This is to prevent compressor from rotate reversely when there is an instantaneous power failure.12.4.6. 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.12.4.7. Dew Prevention 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 willactivate:- Remote Control setting temperature is less than 25°C.- Compressor is on.- Cooling operation mode.- Indoor Fan motor operate at Low fan speed or QLo.• This control is cancelled immediately when above condition is changed.• Dew prevention is control by:1. Increasing Air Flow Volumea. Lo fan speedLo fan speed is changed to Lo+ after 30 min to prevent dew formation.b. QLo fan speedDew formation may occurs at QLo cool, therefore QLo cool is operated only 1 hr 30 min (1 hr QLo, 30 min QLo +100rpm). After that, it operates at QLo +180rpm (However Quiet LED remains on).
