Presence of people and floor 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.
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.

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.

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.
Feet are kept warm and comfortable while reducing uncomfortable drafts.

Drafts are

Feet are
warm, but draft
is strong.
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.

Feet get cold, because warm
air collects near the ceiling.
Area near floor doesn’t reach set
temperature and feet feel cold.
For this reason, we end up
raising the temperature setting.
Uncomfortable draft occurs,
because air is blown downward.
To avoid draft, air direction is
changed to horizontal and feet
get cold.

Area around feet gets
too cold because air
conditioner continues
until the temperature
near the ceiling reaches
the set temperature.
Room temperature is
calculated as 27°C in the area which
is in the vicinity of the person.

The tendency of people to raise the temperature too much is prevented, because you are warmed up
from the feet.
20
°C near floor
Automatic control using the
temperature near the person
as the room temperature.
The floor temperature, which is lower, is detected and
warm air is blown downward where no person
is present.
Comfortable because draft is reduced and area around
feet is warm.
In order to
reduce drafts,
air is blown
horizontally
where a
person is
located.

Indoor unit offers 360° airflow discharges air in all
directions with more uniform temperature distribution.
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.
Low operation sound level
850 mm
An antibacterial treatment that uses silver
ions has been applied to the drain pan,
preventing the growth of slime, mould and
bacteria that cause blockages and odours.
(The lifespan of the cartridge depends
on the usage environment, but should be
changed once every two to three years.)
