Presence of people and oor temperature can be
detected to provide comfort and energy savings
Thanks to the individual airflow direction control
function, airflow direction can be individually adjusted
for each air discharge outlet to prevent uncomfortable
drafts and to deliver optimal air distribution.
The sensor detects human presence and adjusts the
airflow direction automatically to prevent drafts.
The sensor detects the floor temperature and automatically
adjusts operation of the indoor unit to reduce the
temperature difference between the ceiling and the floor.

With the Auto airflow direction mode, flaps are
controlled to deliver optimal air distribution for both cooling
and heating operations when there are no people.
Indoor unit offers 360° airflow discharges air in all
directions with more uniform temperature distribution.
When a person is detected, drafts are prevented by
making the flap horizontal.
When a person is not detected for 5 minutes,
the unit automatically returns to controlling the
flaps for an unoccupied room.

Selectable airflow rate: 3 steps and Auto.
(Auto airflow rate is available when BRC1E62 is used.)
Improved energy efficiency thanks to a new heat
exchanger with smaller tubes, DC fan motor, and DC drain
pump motor.
Drain pump is equipped
as standard accessory
with 850 mm lift.

*1.Airflow direction shoud be set to Auto. *2.Draft prevention function is OFF in the initial setting. It can be set ON using the remote controller.
When there is a large difference between the ceiling and floor temperatures, the airflow rate is automatically increased.
When the difference becomes small, the airflow rate is automatically reduced.
*1.Both airflow direction and airflow rate shoud be set to Auto. *2.Draft prevention function is set OFF in the initial setting.

Floor temperature is detected and over cooling prevented.
To increase comfort, Auto airflow rate mode controls the airflow in accordance with
the difference between floor and ceiling temperatures.
The temperature near the person is automatically calculated by detecting the temperature of the floor. Energy is
saved, because the area around the feet does not get too cold.
