MENU OPERATION
8.14 MOTION SENSOR SETTING
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 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 "Running", "Stand-by" or "Stop" on the remote
control switch with the capacity saving.

N O T E
This setting is available only for the air panel with motion sensor.

• 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 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.

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.
8.14.1 Motion sensor setting
• OFF: The operating control function by the motion sensor is
not activated
• HEAT: The operating control function by the motion sensor is
activated when HEAT mode is selected.
• COOL + DRY: The operating control function by the motion
sensor is activated when COOL + DRY mode is selected.
• ALL MODES: The operating control function by the motion
sensor is activated when HEAT or COOL+DRY mode are
selected.
8.14.2 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 "ON", "Standby" or "OFF" on the
remote control switch.
(The default setting is "ON".)
ON:
•
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.
• Standby:
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.
• OFF:
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.
8.14.3 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.)
