High energy saving
z
High COP is realized by using Large heat exchanger, DC rotary compressor, and inverter
technology.
Energy saving control
z
Human sensor catches movements of people in a room, and operates with lower capacity when the room
is empty. When people come back to the room, it automatically returns to previous operating mode.
Energy saving operation by detecting someone’s movement

10°C HEAT Operation
z *Only available with Wireless RC.
The room temperature can be set to go no lower than 10°C,
thus ensuring that the room does not get too cold when not occupied
Caution)
When the room temperature is higher than 10°C, “•10°C HEAT” operation will not start. Operation starts and maintains the room
temperature at 10°C when the temperature drops below 10°C.
When “•10°C HEAT” operation stops, the room set temperature quickly returns to the preset temperature.
Outdoor unit low noise
z *Only available with Wireless RC.
When air-conditioner operates in large capacity, operation noise of outdoor unit will be suppressed. In case
of room temperature being close to setting temperature, operation noise might not decrease.
