The CO
2
C Sensor has two
ComfoNet connectors. This allows
the ComfoNet cable to be looped
through to other devices belonging
to the ventilation system.
By default, the CO
2
C Sensor
controls to a CO
2
value of
1050ppm. Using the ComfoControl
App and/or the display of the
ventilation unit, sensor control can
be adjusted to specific needs.
When connecting a CO
2
C Sensor
to a ventilation system, the
maximum available current and
the power consumption of the
connected components must be
taken into account. The maximum
available current is specified in the
installer manual for the ventilation
units and the ComfoSplitter. The
maximum current consumption of
the CO
2
C Sensor is 40 mA.
Connect the CO
2
C Sensor with
the following cable type: 2x
unshielded twisted pair, solid wire
0.6mm (max. 50m). Specification
as per DIN VDE 0281: JY(St)Y
2x2x0.6. (Preferably with colours
that match the colour coding of
the connectors).
3.4 Installation instructions CO
2
RF
Sensor
The RF signal can be amplified by
installing an additional CO
2
Sensor
or by using an RF repeater.
It is possible to connect eight (8)
CO
2
RF Sensors to the ventilation
unit.
The RF link to a ventilation unit
will only work if the CO
2
Sensor is
placed within range of this unit. If
several sensors are used, at least
one CO
2
Sensor must be mounted
within range of the ventilation
unit. The other CO
2
Sensors can
be mounted outside the range of
the ventilation unit. However, they
must be mounted within the range
of the previously installed CO
2
Sensor. The RF pairing should be
within range of the ventilation unit.
The RF repeater function does not
work during pairing.
3.5 Installation instructions CO
2
0-10V
Sensor
When a CO
2
010V Sensor is set
up as a sensor, the possibility of
manually selecting ventilation
modes is disabled.
The setup of the CO
2
010V Sensor
as a sensor can only be done with
the Zehnder ventilation units with
a control function. Please refer to
the ventilation unit manual.
