The KNX UK Association members voted Theben’s AMUN 716 air quality sensor, which measures CO2, temperature and humidity as Product of the Year for 2008. The announcement was made at the Associations AGM and the award was presented to Stephen Payne, Theben’s KNX UK Sales Manager (pictured right) by Association president Iain Gordon.

Theben KNX products are marketed in the UK by its subsidiary company Timeguard Limited and details of the company’s KNX range are available at www.timeguard.com.

KNX is the world’s only approved open-source building control standard and puts the intelligence into intelligent buildings. It enables the integration of KNX-compatible products, which are available from a wide range of manufacturers. Programming and control is achieved using a single software tool. KNX products are all thoroughly tested for compliance, ensuring they operate seamlessly together on a single network.

The KNX (UK) Association has been formed by a partnership of UK manufacturers, integrators and training establishments along with other interested parties to promote the KNX standard within the UK.

KNX-compliant products available for control of:

  • Lighting
  • HVAC
  • Blinds
  • Audio visual systems
  • Household appliances
  • Energy Management and much more
  • The Theben air quality sensor

Theben, one of Europe’s leading proponents of the KNX standard, has introduced a unique wall mounted sensor that monitors carbon CO2, temperature and humidity, to enable building managers to manage air quality. The AMUN716 KNX will be especially useful in conference and meeting rooms, classrooms, low-energy homes and conservatories.

Thresholds for each of the three parameters – CO2 levels, humidity and temperature – can be managed separately using KNX building control software.

Other equipment on the KNX bus can be switched if thresholds are either exceeded or not reached, as appropriate. The Theben sensor therefore gives building managers full flexibility in optimising room environments by controlling ventilators, heaters, automatic window openers etc. Theben also offers KNX fan coil actuators for HVAC control.

Theben believes this to be the only sensor measuring CO2 with a KNX bus terminal. It is widely recognised that concentration can waver when CO2 levels reach of just 0.1% (1000ppm). With fresh air containing 0.35% CO2 and exhaled air carrying 4%, ambient levels in busy or closed room can quickly reach levels where concentration fades.
