FUNCTION MENU
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 flow volume and the air flow direction)
automatically depending on a situation.

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.
