2 stage
Previous turbo fan
In the case of a
conventional fan, the air
outlet range was narrow
as the airow 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 airow
streams.

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.
Economy operation
z
The power consumption can be reduced.
FUNCTION SETTING

Outlet direction selection
z
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
z
Air reaches sufciently up to 3m height, even it is compact cassette type.
Also delivers air to high ceilings by selecting the mode and raising the air ow according to the
height of the ceiling.
