Powerful operation
z *Only available with Wireless RC.
20 minutes continuous operation by maximum airow and maximum compressor speed is
possible. Rapid cooling and heating makes the room comfortable quickly.

Energy saving Program
z *Only available with Wireless RC.
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.

MIN. HEAT Operation
z *Only available with Wireless RC.
The room temperature can be set to go no lower than 50°F (10°C),
thus ensuring that the room does not get too cold when not occupied
Caution)
When the room temperature is higher than 50°F (10°C), “•MIN. HEAT” operation will not start. Operation starts and maintains the room
temperature at 50°F (10°C) when the temperature drops below 50°F (10°C).
When “•MIN. 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.

and the maximum electric value of the outdoor
unit is suppressed.
