Temperature
Control
The temperature of the room is detected by the room temperature thermistor. However, there is
difference between the temperature detected by room temperature thermistor and the temperature
of lower part of the room, depending on the type of the indoor unit or installation condition.
Practically, the temperature control is done by the target temperature appropriately adjusted for the
indoor unit and the temperature detected by room temperature thermistor.

(Dual) Flap(s)
The large flap sends a large volume of air downward to the floor and provides an optimum control in
cooling, dry, and heating operation.
Cooling/Dry

and distributed all over the room.
