14.10 MOTION SENSOR
This function is available only when the motions sensor is
equipped with the air panel.
The motion sensor detects a human activity by the change of
the infrared light.
This function saves the air conditioning capacity (adjusting the
set temperature, the air ow volume and the air ow direction)
automatically depending on a situation.
The operation after the motion sensor detects as absence can
be selected from “Running”, “Stand-by” or “Stop” on the remote
control switch with the capacity saving.
? NOTE
This setting is available only for the air panel with motion sensor.
! CAUTION
• Do not use the motion sensor function when a baby or a handicapped
person stays by oneself. The motion sensor may detect as absence
and the operation may be stopped in the case of staying for long time
with a bit motion.
• The motion sensor detects the human activity. However, if someone is
in a room with a bit motion, the motion sensor may detect as absence.
• The motion sensor may detect as human activity if the indoor unit
with the motion sensor is installed near a moving object (ex. swing
operation of a heating appliance) which is di󰀨erence in temperature
against atmosphere.
• In the case that the indoor units are operated by 2 remote control
switches, the motion sensor setting is available only from the main
remote control switch.
• The indoor unit operation can be stopped by the motion sensor
control.
• While the air conditioning capacity is saved or the operation is
stopped by the motion sensor control, “Motion sensor is activated” is
displayed on LCD.
• If the function “Prohibiting operation by remote control switch” is used
from the centralized controller, select the command “Running” or
“Stand-by” in “If absent” at the motion sensor control setting.
• If “Stop” is selected, the motion sensor control can not be performed
correctly as follows:
- In the case that “Stop” is selected in the motion sensor control
setting and “Prohibiting operation by remote control switch”
(for all items) is set by the centralized controller, the operation
will not be stopped even if the motion sensor control function
changes to the stoppage condition.
- In the case that “Stop” is selected in the motion sensor control
setting and “Prohibiting operation by remote control switch” (for
part of items) is set by the centralized controller, the indoor unit
operation can not be restarted from the centralized controller
although the operation can be stopped under the stoppage
condition by the motion sensor control function.
