13.5. 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.
s T = Intake air temperature - Indoor heat exchanger temperature
• This is to prevent compressor from rotate reversely when there is an instantaneous power failure.
13.6. Dew Prevention Control
• To prevent dew formation at indoor unit discharge area.
• This control starts if:
- Cooling mode is activated.
- Remote Control setting temperature is less than 25°C.
- Fan speed is at CLo 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.
- The angle of horizontal louver will be changed as below figure.
• Dew prevention stop condition
- Remote control setting temperature is more than 25°C.
- Fan speed is not set to CLo or QLo.
