12. Operation 

Control 

12.1 Basic Function 

12.1.1  Internal Setting Temperature 

Once the operation starts, remote control setting temperature will be taken as base value for temperature shifting 
processes. These shifting processes are depending on the air conditioner settings and the operation environment. 
The final shifted value will be used as internal setting temperature and it is updated continuously whenever the 
electrical power is supplied to the unit. 
  
 
 
 
 
 
 
 
 
 
 
 
 

12.1.2  Cooling Operation

• Compressor is OFF when Intake Air Temperature - Internal Setting Temperature < -1.5

 

• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature > 

Compressor OFF point.

12.1.4.1 Thermostat 

control 

• Compressor is OFF when Intake Air Temperature - Internal Setting Temperature > +2.0

 

• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature< 

Compressor OFF point. 

12.1.5 Automatic 

Operation 

• Once AUTO mode is selected, operation mode is determined by set temperature of remote control and indoor 

intake temperature.
