Instruction Manual

5.9 MOTION SENSOR SETTING
This function and its settings are available only for indoor
units equipped with a motion sensor. The motion sensor can
be integrated into the front panel of the unit or a separate
accessory.
The motion sensor monitors human activity using infrared signals.
When the motion sensor is activated, Auto-Save and Crowd
sense functions are enabled (for compatible units), allowing
the system to run energy saving procedures, maintaining the
comfort of the users.
Auto-Save function: the cooling or heating capacity of the
system is reduced when a room is getting less occupied. When
human activity is detected in the room, normal operation of the
system can be resumed.
Crowd-Sense function (for compatible units only): the cooling
or heating capacity of the system can be adjusted automatically
according to the level of occupancy of the room, to avoid a room
temperature increase when the area is crowded
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.
! 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 the level
of activity in the room is too low (for example if someone is in a room
with bit activity), the motion sensor may detect as absence.
• The motion sensor may detect as human activity any moving
object generating a temperature difference with the room ambient
temperature. Example: auto-swing operation of any heating system
installed near the indoor unit equipped with the motion sensor.
• 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.
• In case Auto-Save and Crowd-Sense functions are applied to indoor
units that are managed by a Central Controller (CSNET Manager
or Central Stations), the following limitations must be considered to
avoid unexpected behaviour of the system:
- Do not select “Stop • Detect” setting for the “If absent” mode
when indoor units remote controller settings are locked by the
Central Controller (partial lock or full remote controller lock).
- More generally, it is recommended to use “ON” or “Standby”
settings for the “If absent” mode when a Central Controller is
used on the related VRF system.
- These settings are recommended to avoid unexpected control of
the indoor units, such as:
- Indoor unit operation not stopped by the motion sensor
control when the “If absent” sequence is engaged.
- Indoor unit operation not resumed by the motion sensor
control when human activity is detected.
5.9.1 Motion sensor selection
1 Select “Motion Sensor Setting” on the “Function Menu”
screen and press “OK”.
2 Press “ ” or “ ” to select “Sensor”, and then press “OK”.
3 Press “ ” or “ ”, the sensor changes as follows:
“All modes” ↔ “Cooling+dry” ↔ “Heat” ↔ “Disable”.
Select the sensor and press “OK”.
Press “
” to return to the “Function Menu” screen.
• All modes: The operating control function by the motion
sensor is activated when HEAT, COOL or DRY mode is
selected.
• Cooling+Dry: The operating control function by the motion
sensor is activated when COOL or DRY mode is selected.
• Heating: The operating control function by the motion sensor
is activated when HEAT mode is selected.
• Disable: The operating control function by the motion sensor
is not activated.
