7. Motion Sensor
This setting is available only for the Hiwall unit with
motion sensor.
7.1 Function
l 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.
2 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.
l 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.
2 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.
3 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
different in temperature against atmosphere.
4 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.
5 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.
6 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 of wired handset - PC-ARF.
7 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.

7.2 Details for Motion Sensor Control
The motion sensor control adjusts automatically
the following items depending on a situation.
* Setting Temperature:
The temperature is adjusted 1oC or 2oC for
saving capacity.
* Air Flow Volume:
The air flow volume is adjusted to lower one
volume or to “Slo” (except during the dry
operation).
* Air Flow Direction:
The air flow direction is adjusted to horizontal.
7.3 Descriptions for Setting Items
l Motion Sensor Setting
* ON: The operating control function by the
motion sensor is activated.
* OFF: The operating control function by the
motion sensor is not activated.
(The default setting is “ON”.)
2 If absent
“If absent” is set for the indoor unit operation
after the motion sensor detects as absence for
set time in “Check interval”. The operation can
be selected from “Running”, “Stand-by” or “Stop”
on the remote control switch.
(The default setting is “Running”.)
* Running:
The operation is continued with saving the
capacity after detected as an absence.
If the human activity is detected for a period of
time, the normal operation will be performed
again.
* Stand-by:
The operation mode is the fan operation at “Slo”
speed. If the human activity is detected for
a period of time, the normal operation will be
performed again.
* Stop:
The operation is stopped by the remote control
switch when all the indoor units with motion
sensor detect absence which are connected
with same remote control switch.
If the human activity is detected for a period of
time by the stoppage, the normal operation is
performed again.
3 Check Interval
When the motion sensor detects an absence
at selected check interval time, the function “If
absent” will be executed. The interval can be
selected from 30, 60, 90 120 or 180 minutes.
(The default setting is 30 minutes.)
