HOW THE AIR CONDITIONER WORKS
Automatic Operation
As shown in Figures 1 and 2, Automatic Operation mode selects the operation based on the room tempera-
ture data (Ta) when operation begins.

The operation mode is selected again after the compressor has remained stopped for 15 minutes.
Hi POWER operation
When you push the Hi POWER button during cooling, heating or A operation, the air conditioner starts the
following operation.
• Cooling operation
The cooling operation is performed at 1°C lower than the temperature setting.
When the room temperature is higher than the temperature setting, the air flow is directed downward.
The fan speed is also set to high*.
Once the room temperature is within 1°C of the set temperature, the air flow is returned to its previous
direction.
* The noise level increases, according to the fan speed.
• Heating operation (heat pump models)
The heating operation is performed at 2°C higher than the set temperature.
The air flow direction and fan speed are automatically switched according to the operating condition.
ECO operation
When you push the ECO button during cooling, heating or A operation, the air conditioner starts the following
operation. The fan speed is controlled automatically.
• Cooling operation ( )
In the minimum operation zone, where the air conditioner is operated at minimum capacity, overcooling is
prevented by raising the set temperature.
The room temperature is thus regulated between the minimum operation zone and the set temperature.
• Heating operation (
) (heat pump models)
In the minimum operation zone, where the air conditioner is operated at minimum capacity, overheating is
prevented by lowering of the set temperature.
The room temperature is thus regulated between the set temperature and the minimum operation zone.
Dry operation ( )
The dry mode automatically selects the cooling dry operation based on the difference between the set
temperature and the actual room temperature.
The fan speed indicator shows AUTO and low speed is used.
