● Motion Sensor
(1) A decorative panel with a motion sensor can intelligently detect human activity and furniture heat
signatures.
Air conditioning comfort is improved with four motion sensors and one heat-detecting sensor equipped
with the decorative panel.
Motion Sensor
Infrared is always radiated from humans and objects.
The motion sensor uses infrared in a “detecting area” to detect human energy.
Radiation Sensor
The radiation sensor measures the temperature in its detecting area through radiated infrared from
human and objects.

Detecting Area of Motion Sensors
(Viewed from Ceiling)
The motion sensors’ detecting area is divided
into four separate areas as shown above.
Motion Sensor
Four motion sensors are installed
in this area.

NOTE:
1. The motion sensor detects human activity. However, if someone is in a room with very little activity,
the motion sensors may not detect motion.
2. The motion sensor may detect human activity if the indoor unit with the motion sensor is installed
near a moving object which has a temperature different than the environment.
3. The motion sensors may detect no activity if the indoor unit is installed on a high ceiling of 13.1 ft. (4m)
or more, or fingerprints or contaminants are on the motion sensors’ lenses, even if someone is in a
room.
