HOW THE AIR CONDITIONER WORKS

Automatic operation
• The air conditioner selects and operates in one of the operating modes of cooling, heating, or fan only,
depending on the room temperature.
• If the AUTO mode is uncomfortable, you can select the desired conditions manually.
Room temperature in operation
The set temperature +1°C or higher
(in case that the room is hot )
The set temperature –1°C to +1°C
The set temperature –1°C or lower
(in case that the room is cold )
Hi POWER operation
When you press the Hi POWER button during cooling, heating or A operation, the air conditioner will start the
following operation.
•
Cooling operation
Performs the cooling operation lower than the setting temperature.
When the room temperature is above the setting temperature, air flow is directed downward. In addition, fan
speed is high*. Once room temperature is within 1°C of the setting temperature, air flow is returned to its
regular direction to cool the entire room with maximum efficiency.
* Noise level raises in accordance with fan speed.
•
Heating operation
Performs the heating operation at 2°C higher than the setting temperature.
ECO timer operation
When you press the ECO button during cooling, heating or A operation, the air conditioner will start the following
operation.
The fan speed will be automatically controlled.
• Cooling operation ( )
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.
• Heating operation ( )
In the operation suppression zone, where capacity is kept to the
minimum, overheating is prevented by lowering 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 set
temperature and the operation suppression zone.
