2 Product description
The CO2 sensor is a wireless sensor that measures the carbon
dioxide (CO2) level in the air. The CO2 level is measured in
Parts Per Million, PPM. If the sensor detects CO2 above a
preset level, the air handling unit will start forced ventilation.
The CO2 sensor is intended for wall mounting either on the
wall or on a wall-box, however it should be placed where you
want instantaneous for CO2.

seconds.
• When the button is pushed and held for less than 1 second,
a Party Active message is sent to the gateway.
Note: It is not possible to deactivate the Party Active mode
from this module. It must be deactivated on the air handling
unit control panel or the wireless control panel if one is
used.
Note: There is no (visible) feedback when the button is
touched.
• When the button is pressed and held for 10 seconds, the
green LED starts flashing for 3 seconds.
