CO2 sensor bedroom (up to
8 rooms)
External CO2 sensor input.
This object has to be connected to a KNX sensor that is mounted in a bedroom. Depending on
the measured CO2 level, the ComfoConnect KNX C forces the ventilation unit to run at a minimum
ventilation preset.
�
< 800 ppm: set to ventilation preset 1 at least;
�
≥ 800 ppm: set to ventilation preset 2 at least.
9.008
CO2 sensor bedroom (set)
(up to 8 rooms)
CO2 sensor room
(up to 8 rooms)
External CO2 sensor input.
This object has to be connected to a KNX sensor that is mounted in another room other than a
bedroom. Depending on the measured CO2 level, the ComfoConnect KNX C forces the ventilation
unit to run at a minimum ventilation preset.
�
< 800 ppm: set to ventilation preset 1 at least;
�
≥ 800 and < 1200 ppm: set to ventilation preset 2 at least;
�
≥ 1200 ppm: set to ventilation preset 3 at least.
CO2 sensor room (set)
(up to 8 rooms)
Humidity sensor bathroom
(up to 8 rooms)
External humidity sensor input.
This object has to be connected to a KNX sensor that is mounted in a bathroom. Depending on the
measured humidity level, the ComfoConnect KNX C forces the ventilation unit to run at a minimum
ventilation preset.
�
< 35%: set to ventilation preset 1 at least;
�
≥ 35%: set to ventilation preset 2 at least.

Error1
�
False: all systems are operational;
�
True: the ventilation unit reported an error. Manual inspection and/or intervention is required.
Check the error that is indicated on the display of the ventilation unit.
1.002
Filter replace1
Hours till the ventilation units filter needs replacement.
7.007
Filter dirty1
�
False: the ventilation units filters do not need replacing at this moment;
�
True: the ventilation units filters need replacing.
1.002
State
State/error of the unit:
�
0: a connection with the ventilation unit has been established, no error;
�
30: another unit is detected; this unit is not connected to the ventilation unit;
�
40: incompatible ventilation unit version detected; cannot connect to the ventilation unit;
�
50: no ventilation unit detected.
For safety, when the state of the unit has any other value than 0, the Error object is set to True and
Standby is set to On.
