The Air Quality Sensor KNX AQS measures the room CO2 concentration and so provides a reliable information if the air is really “fresh”. From 1000 ppm on (equals 0.1%), the air is perceived as „stale“ – In this case the KNX AQS can send aeration commands to automatically controlled windows or ventilation units in the KNX bus system.

The air quality sensor can receive an external CO2 value via the bus and process it with the own data to an overall value (mixed value, e. g. average pollution of room). The KNX AQS provides four switching outputs with adjustable threshold values as well as AND and OR logic gates. The integrated PI controller alllows for control of a ventilation and thus helps to maintain the required CO2 content value for room air.

Functions and Operation

  1. Measurement of CO2 concentration of the air
  2. Mixed value from own measured value and external value (proportions can be set in percentage)
  3. PI controller for ventilation (one or two step)
  4. 4 switching outputs with adjustable threshold values (Threshold values can be set by parameter or via communication objects)
  5. 2 actuating variable comparators for output of minimum, maximum or avarage values. Each with 5 inputs (for values received via communication objects)
  6. 8 AND and 8 OR logic gates with each 4 inputs. Every switching incident as well as 8 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
  7. Configuration is accomplished by means of the KNX software ETS
