Overview

  • Detection of air quality
    (CO2-concentration, rel. humidity, temperature)
  • CO2-sensor (Measuring range 425...5.000 ppm air pressure compensated)
  • CO2-value is atmospheric pressure compensated
  • Sensors for CO2-, temperature, humidity and atmospheric pressure measurement
  • Temperature sensor (Measuring range 0...+50 °C)
  • Humidity sensor (Measuring range 0...100 % rel. humidity)
  • Humidity comparator function
  • 2 separate temperature controls via KNX
  • Temperature control with up to 4 sensor values possible
  • Up to 2 VAV controls possible
  • 5 binary and analogue inputs (e.g. for connecting an external temperature sensor)
  • 3x analog outputs (0–10 V)
  • RGB, RGBW and Tunable White dimming function
  • KNX Secure
  • Updatable
  • Clearly structured ETS
  • Easy installation and mounting
  • Modern and planar design
  • Wall mounting [80 mm]
  • Party function
  • Additionally at GS 41.12 knx:
    manual adjustment of set-point temperature via touch panel
