Motion Sensor

This setting is available only for the motion sensor
kit.

9.1 Function

● 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 flow
volume and the air flow direction) automatically
depending on a situation.
● The operation after the motion sensor detects as
absence can be selected from "ON", "Stand-by"
or "OFF" on the wired controller with the capacity
saving.
● 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
difference in temperature against atmosphere.
● In the case that the indoor units are operated by
2 wired controllers, the motion sensor setting is
available only from the main wired controller.
● The indoor unit operation can be stopped by the
motion sensor control.
NOTE:
The indoor unit without the motion sensor and
the indoor unit with the motion sensor can be
mixed to install.
In this case, when the operation is stopped by
the motion sensor control, the indoor unit without
the motion sensor will also stop the operation.
● 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 wired
controller" is used from the centralized controller,
select the command "ON" or "Stand-by" in "If
absent" at the motion sensor control setting.
If "OFF" is selected, the motion sensor control
can not be performed correctly as follows.
* In the case that "OFF" is selected in the
motion sensor control setting and "Prohibiting
operation by wired controller" (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 "OFF" is selected in the
motion sensor control setting and "Prohibiting
operation by wired controller" (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.
9.2 Details for Motion Sensor Control
The motion sensor control adjusts automatically
the following items depending on a situation.
* Setting Temperature:
The temperature is adjusted 1
saving capacity.
* Air Flow Volume:
The air flow volume is adjusted to lower one
volume or to "Slow" (except during the dry
operation).
* Air Flow Direction:
The air flow direction is adjusted to horizontal.
