13.6. 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
q
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.
13.7. Dew Prevention control
• To prevent dew formation at indoor unit discharge area.
• This control start if:-
- Cooling mode or Quiet mode is activated.
- Remote Control setting temperature is less than 25
q
C.
- Fan speed is at CLo or QLo.
- Room temperature is constant (±1
q
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 table below:
• Dew prevention stop condition.
- Remote control setting temperature is more than 25
q
C.
- Fan speed is not set to CLo or QLo.
- Select Powerful operation
