8.4.5. Compressor Reverse Rotation Protection Control

 • 

If the compressor is operating continuously for 5 minutes or longer and the temperature difference between intake air and
indoor heat exchanger is 4.5°F 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.

8.4.6. 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.

8.4.7. Anti-Dew Formation Control

 • 

Purpose is to prevent dew formation on indoor unit air discharge area.

 • 

When room temperature is constant (±1.8°F) the following conditions occur for 30 minutes continuously, anti-dew formation will
activate:

 − 

Remote Control setting temperature is less than 77°F.

 − 

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.

 • 

Anti-Dew formation is control by:
 1. Increasing Air Flow Volume

 a. Lo fan speed

Lo fan speed is changed to Lo+ after 30 min to prevent dew formation.

 b. QLo fan speed

Dew formation may occurs at QLo cool, therefore QLo cool is operated only 1 hr 30 min (1 hr QLo, 30 min QLo +100
rpm). After that, it operates at QLo +180rpm (However Quiet LED remains on).
