control

(2) The set temperature is corrected using various sensor data within

 

 

 

the range where comfort is maintained.

 

 

 

(3) By using various sensor data including room temp. Ta, outside air

 

 

 

temp. To, fan speed, and indoor unit heat exchange sensor temp.

 

 

 

Tc, 20-minute data is averaged to calculate a set temperature

 

 

 

correction value.
