Motion Sensor Control
The air conditioning capacity is saved automatically depending on a situation and the amount of detected
human activity by adopting the motion sensor on the corner of the lower cover. The energy saving can be
improved more with the individual operating function. In addition, the operation can stop automatically if the
absent situation continues for more than 30 minutes
more comfortable and reduces unnecessary operations

• Detecting Area for Human Activity
Detecting Diameter: Approx. 7.0m x 7.2m
(0.8m...height from floor surface)
The motion sensor may not detect human
activity just under the indoor unit
(1.8m x 7.0m).
: The detecting area is smaller if a person in

the room hardly moves just like when one
stretches on a chair, etc. The detecting
diameter can change to approximately 6.0m.
NOTICE: Motion Sensor
1. The motion sensor detects human activity. However, if someone is in a room with a bit motion, the
motion sensor may detect the absence of human.
2. The motion sensor may detect human activity, if the indoor unit with the motion sensor is installed near
a moving object having different temperature from ambient atmosphere.
3. The motion sensor may detect the absence of human even if someone is in a room, when the indoor
unit with the motion sensor is installed on a high ceiling (higher than 4m).
The outdoor unit connectable to the motion sensor kit is limited. Refer to the table "Corresponding
Outdoor Units for Motion Sensor Function" in the item 6 for the corresponding models.
at Normal Operation
at Motion Sensor Activated
In a specific room, the air flow volume
and the air flow direction are adjusted
when there is little human activity
for a period of time.
ATTENTION:
Do not use the motion sensor function when a baby or a handicapped person stays alone.
The motion sensor may detect the absence of human and the operation may stop in the case of someone
staying for long time with a bit motion.
