    The current state of the temperature controller can be indicated by LEDs. 
  • Heating or cooling 
  • Slow pulsing if controller is active 
  • Pulse depth represents deviation between actual- and setpoint-temperature 
  • Display for comfort / standby / night mode configurable 
    Four logic blocks for the logical link between internal and external signals. 
  • 10 associated logic inputs / outputs 
  • Heat- and cooling-request as additionally available signals 
  • Functions "AND, OR, NOT, XOR" for binary logic 
  • Functions "+ - *" for 8-bit values 
  • Function "=" for conditional forwarding of events 
  • Detection and control of room temperature 
  • Detection of CO2 level 
  • Decentralized control for steady KNX-valves or thermal actuators 
  • Decentralized ventilation control depending on air quality
