HOW THE AIR CONDITIONER WORKS

  AUTOMATIC OPERATION

•  When you set the air conditioner in AUTO mode, it will automatically 

select cooling, heating (cooling/heating models only), or fan only 
operation depending on what temperature you have selected and 
the room temperature.

•  The air conditioner will control room temperature automatically round 

the temperature point set by you.

•  If the AUTO mode is uncomfortable, you can select desired conditions 

manually. 

  ECONOMIC OPERATION

When you push SLEEP button during cooling, heating (cooling only 
type without), or AUTO operation, the air conditioner will start following 
operation. The fan speed will be automatically controlled. In the 
operation suppression zone where capacity is kept to the minimum, 
overcooling is prevented by raising the temperature setting by 1°C after 
1 hour and by 2°C after 2 hours of operation. The room temperature 
is thus regulated between the operation suppression zone and the set 
temperature. (It depends on the outdoor temperature.)

  DRYING OPERATION

•  The dry mode will automatically select the drying operation based 

on the di erence between the set temperature and the actual room 
temperature.

•  The temperature is regulated while dehumidifying by repeating turning 

on and o  of the cooling operation or fan only. The fan speed indicator 
will display AUTO and low speed will be used.
