11.4.6. 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.
11.4.7. Dew Prevention control
• To prevent dew formation at indoor unit discharge area.
• This control will be activated if:-
- Cooling mode or Quiet mode.
- Remote Control setting temperature is less than 25
°
C.
- Fan speed is at Low or QLo.
- Room temperature is constant (±1
°
C) for 30 minutes.
- Compressor is continuously running.
• Fan speed and angle of horizontal louver (vertical airflow angle) will be adjusted accordingly in this control.
- Fan speed will be increased slowly if the unit is in quiet mode but no change in normal cooling mode.
- The angle of horizontal louver will be changed as below figure.
Note:
A = Normal operation angle of rotation
B = Dew prevention angle of rotation
Horizontal Louver Angle
During Anti-Dew condensation prevention, the horizontal louver angle in Auto-control are as below figure.
During Anti-Dew condensation prevention, the horizontal louver angle in Manual control are as below figure.
