3. Hot Start 
When the heating operation starts, the indoor fan stops and the compressor run with a certain frequency. 
This is to prevent the cold airflow from blowing. 
If the piping temperature rises to 19 

℃

, and the indoor fan speed and airflow direction varies with the indoor piping 

temperature, the hot start control is completed.

 

13.3.2  Overload Protection Control 

The frequency for the compressor is determined by indoor piping temperature.

13.3.3  Demand Control 

 

When the air-conditioner connected to Demand Response Enabling Devices (DRED), the power 
consumption especially during peak hours could be controlled. 

 

 
 
 
 
 
 
 
 

 

Three Demand response modes (DRM) are available

 

 

  DRM1 = Compressor cut off

 

  DRM2 = Operate at 50% of rated input power 

  DRM3 = Operate at 75% of rated input power 

 

 

During DRM, the Power Indicator blinks (3 seconds ON and 0.5 seconds OFF)
