Reflects the room temperature sensor which is connected to the ventilation unit (if available)
Reflects the extract air sensor of the ventilation unit (SENSOR_ETA).
Reflects the exhaust air sensor of the ventilation unit. (SENSOR_EHA)
Reflects the outdoor air sensor of the ventilation unit.( SENSOR_ODA)
Reflects the supply air sensor of the ventilation unit. (SENSOR_SUP)
Reflects the room humidity sensor which is connected to the ventilation unit (if available)
Reflects the extract air sensor of the ventilation unit (HUMID_ETA).
Reflects the exhaust air sensor of the ventilation unit. (HUMID_EHA)
Reflects the outdoor air sensor of the ventilation unit.( HUMID_ODA)
Reflects the supply air sensor of the ventilation unit. (HUMID_SUP)
External CO 2 sensor input.
This object has to be connected to a KNX sensor that is mounted in a bedroom. Depending on
the measured CO 2 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.
External CO 2 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 CO 2 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.
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.
� 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.
Hours till the ventilation units filter needs replacement.
� False: the ventilation units filters do not need replacing at this moment;
� True: the ventilation units filters need replacing.
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.
