KNX VOC-UP basic, white (discontinued item)

KNX Mixed Gas Sensor


The Mixed Gas Sensor KNX VOC-UP basic recognizes volatile organic compounds in the room air. The indoor sensor can receive an external VOC value via the bus and process it with the own data to an overall value (mixed value, e. g. room average).

The KNX VOC-UP basic provides four switching outputs with adjustable threshold values. The switching outputs and further communication objects can be linked by AND and OR logic gates. Additionally, an integrated actuating variable comparator can compare and output values that are received via communication objects. An integrated PI controllers allows for control of ventilation depending on VOC concentration.

The housing is completed with a frame of the switching series installed in the building and thus merges with the interior.

Delivery without frame

  • Measurement of VOC (volatile organic compounds) in the air. In this process, an air quality value in CO2 equivalents is calculated via an algorithm from the sum signal of all compounds included in the mixed gas.
  • Mixed value from own measured value and external value (proportions can be set in percentage)
  • PI controller for ventilation depending on VOC concentration: dehumidification/humidification (one step) or dehumidification (one or two step)
  • 4 switching outputs with adjustable threshold values (Threshold values can be adjusted per parameter or via communication objects)
  • 8 AND and 8 OR logic gates with each 4 inputs. Every switching incident as well as 16 logic inputs in the form of communication objects may be used as inputs for the logic gates. The output of each gate may optionally be configured as 1 bit or 2 x 8 bits
  • 2 actuating variable comparators for output of minimum, maximum or average values. Each with 5 inputs (for values received via communication objects)
  • Configuration is made using the KNX software ETS
