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.
