with integrated BCU
with humidity sensor and room temperature controller
with integrated push-button interface 2-gang

Intended use

  • Measurement of CO2 concentration, relative air humidity and air temperature
  • Output of the measured values as telegram to the bus, e.g. for controlling fans or window drives via KNX telegrams
  • Single-room temperature control in KNX installations
  • Mounting in wall boxes

Product characteristics

  • Limit value monitoring for CO2 concentration (max. 4 threshold values) and air humidity (max. 2 threshold values)
  • Dew point alarm e.g. for cooling blankets and conservatories, to avoid mould formation
  • Two binary inputs for connection of floating contacts e.g. buttons, switches, window contacts
  • Logic gates for simple gating functions
