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 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.
8.4.6. 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°C) 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 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).
