Previous turbo fan
In the case of a
conventional fan, the air
outlet range was narrow
as the airflow moved to
the motor side which
meant the velocity of air
passing through the heat
exchanger was uneven.
2-stage turbo fan
A evenly spread air distribution across
the heat exchanger is possible due
to the new 2 stage turbo fan which
produces two separate airflow
streams.

10°C HEAT Operation
 *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.
Economy operation

The power consumption can be reduced.
FUNCTION SETTING

Outlet direction selection

Performs operation matched to the number of outlets when 4 directions are unnecessary and•
outlets are blocked when the ceiling cassette is installed in a corner, etc.
4-way direction 3-way direction
4-way direction mode: Set when there are 4 outlets
(shipped state).
3-way direction mode: Set when there are 3 outlets.
Ceiling switching function

Air reaches sufficiently up to 3m height, even it is compact cassette type.
Also delivers air to high ceilings by selecting the mode and raising the air flow according to the
height of the ceiling.

Auto restart

The units restart automatically when the current was returned even when there was a power
interruption during operation.
