Optional Optional
• Highly accurate people detection
A total of eight sensors fully rotate 360° in
3-minute intervals. In addition to
detecting human body temperature,
an original algorithm also detects
people's positions and the
number of people.
• Detects number of people
Room occupancy energy saving mode
The 3D i-see Sensor detects the number of people in the
room. It then calculates the occupancy rate based on the
maximum number of people in the room up to that point in time
to save air-conditioning power. Air-conditioning power
equivalent to 1°C is saved during both cooling and heating
operations at an occupancy rate of approximately 30%. The
temperature is controlled according to the number of people.
No occupancy energy saving mode
When 3D i-see Sensor detects no one in the room, the system
is switched to a preset power-saving mode. If the room remains
unoccupied for more than 60 minutes, air-conditioning power
equivalent to 2°C is saved during both cooling and heating
operations. This contributes to preventing waste in terms of
heating and cooling.
No occupancy Auto-OFF mode
When the room remains unoccupied for a preset length of time,
the air conditioner turns off automatically, thereby providing
even greater power savings. The time until operation is stopped
can be set in intervals of 10 minutes, from 60 to 180 minutes.
*No occupancy Auto-OFF mode is not available when multiple indoor units are
operated by a single MA remote controller.
• Detects people's positions
Direct/indirect settings*
Some people do not like the feeling of wind,
while others want to be warm from head to toe.
People's likes and dislikes vary. With the 3D
i-see Sensor, each vane can be set to block or
not block the wind.
*PAR-40MAA or PAR-SL100A-E is required for each setting.

<When cooling>
Saves energy while keeping a
comfortable effective temperature
by automatically switching between
ventilation and cooling. When the
pre-set temperature is reached, the
air conditioner switches to swing
fan operation to maintain the
effective temperature. This clever
function contributes to keeping a
comfortable coolness.

<When heating>
The air conditioner automatically switches
between circulation and heating. Wasted
heat that accumulates near the ceiling is
reused via circulation. When the pre-set
temperature is reached, the air conditioner
switches from heating to circulation and
blows air in the horizontal direction. It
pushes down the warm air that has
gathered near the ceiling to people's
height, thereby providing smart heating.
