■
The top LED turns red: this is the
pairing mode to generate a new
RF address for the ventilation unit.
Previously­registered units must then
be paired again in standard pairing
mode.
5. After the above selection, press the
operating button for 5 seconds to
confirm the selection. After this, the
pairing between the CO
2
Sensor and the
ventilation unit starts.
1. The CO
2
LED flashes orange, and the
selected pairing mode LED flashes
red. The ventilation unit is being
sought. This may take some time.
2. The CO
2
LED flashes orange and the
selected pairing mode LED flashes
green. Previously paired CO
2
Sensors
are being sought. This may take
some time.
3. The pairing worked: The three LEDs
on the right blink green 3 times.
4. The pairing failed: The three LEDs
on the right blink red 3 times.
6. Repeat the complete procedure for
pairing the next CO
2
Sensor, including
resetting the ventilation unit to active
pairing mode.
Pairing a CO
2
Sensor usually takes
1 minute.
If the pairing has failed, try pairing
the CO
2
Sensor by holding it closer
to the ventilation unit.
With an active pairing mode
on a ventilation unit, there are
10 minutes to pair one CO
2
Sensor.
For each additional CO
2
Sensor to be
paired, the 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
2
LED blinks green.
3. The bottom LED on the right flashes
red and the CO
2
LED flashes green 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 the 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
2
Sensor takes over
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
2
Sensor.
The ventilation unit takes over the
RF address of the CO
2
Sensor.
Previously­registered 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 ventilation unit.
