Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time 
passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating 
mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and 
performing temperature shifting. The compressor at outdoor unit is operating following the frequency instructed by 
the microcomputer at indoor unit that judging the condition according to internal setting temperature and intake air 
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. 

  Compressor is OFF when Intake Air Temperature - Internal Setting Temperature < -1.5°C continue for 3 minutes. 

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

Compressor OFF point. 

  Compressor is OFF when Intake Air Temperature - Internal Setting Temperature < -2.5°C continue for 3 minutes. 

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

Compressor OFF point.

  Compressor is OFF when Intake Air Temperature - Internal Setting Temperature ≥ +2.0°C continue for 3 minutes. 

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

Compressor OFF point. 

  This mode can be set using remote control and the operation is decided by remote control setting temperature, 

remote control operation mode, indoor intake air temperature and outdoor air temperature. 

  During operation mode judgment, indoor fan motor (with speed of Lo-) and outdoor fan motor are running for 30 

seconds to detect the indoor intake and outdoor air temperature. The operation mode is decided based on below 
chart. 

 

 

 
Every 30 minutes, the indoor and outdoor temperature is judged. 
The Auto Operation Mode shifting will take place whenever operation mode changed from Cooling/Dry to Heating or 
vice versa.

(1) When the area control is in operation, the minimum rotation speed is limited as outlined below depending on the human position area. 

 

COOL & COOL DRY 

Same as the fan speed in the powerful mode. When the airflow is stable, the minimum rotation speed is limited to 
“1+2+3” as in the table below. 

HEAT 

Same as the fan speed in the powerful mode. In the range where the airflow is stable and the pipe temperature is high, 
the minimum rotation speed is limited to “1+3” as in the table below. 

FULL DRY 

The rotation speed is fixed at “1+2+3” as in the table below. 

 
Min. rotation speed for each field
