With an active pairing mode on a
ventilation unit, there is
10 minutes to pair one CO
Sensor. For each additional
CO Sensor to be paired, the
2
ventilation unit must be put into
active pairing mode again.
2. Press the operating button for 5
seconds to activate the menu.
1. The three LEDs on the right blink
green 3 times.
2. The CO LED blinks green.

3. The bottom LED on the right flashes
red and the CO
to indicate the RF pairing option.
3. Press the operating button for
5 seconds to confirm the RF link
selection.
■ The three LEDs on the right blink red
3 times to confirm activation of the
RF link.
4. Briefly press the operating button and
select one of the desired parings:
■ The bottom LED on the right turns
red: this is the standard pairing
mode. The CO
the RF address of the ventilation
unit. Previously registered units
remain active.
■ The middle LED turns red: this is
the pairing mode to register an
additional ventilation unit to the
CO Sensor. The ventilation unit
2
takes over the RF address of the
CO Sensor. Previously registered
2
units must then be paired again in
standard pairing mode.
Only use the pairing method
described below if a new RF
address must be assigned to the
