Heating Actuator 1-Gang, Flush-Mounted, KNX

Product code: 2166 00
The device has one electronic switching output, which allows silent control of electrothermal valve drives for heating or cooling systems. Up to 2 electrothermal valve drives can be connected. Besides the output, the device possesses three additional inputs, which affect the KNX separately. With the effect on the bus, the inputs can, independently of one another, transmit telegrams for switching or dimming for Venetian blind control or value encoder use (dimming value encoder, light scene extension). The connection of 230 V signals or other external voltages to the extension inputs is not permitted!
Price (Excluding VAT)


The electronic switching output has the following scope of functions: conversion of constant command value telegrams into a pulse-width modulated output signal (PWM). This provides quasi-constant activation of the connected valve drives. Alternatively, conversion of switching command values. Status messaging for valve position and cyclical monitoring of the command value telegrams. Emergency operation in the event of bus voltage return and forced position via bus telegram in summer and winter mode. Alarm message in case of short-circuit or overload of the switching output and anti-sticking protection for the valves. Valve drives that are closed or open when deenergised can be connected. The status message "valve closed" can be transmitted to the bus for further processing or displaying the information on other bus devices.

Heating output:

  • Output, can be controlled via a corrected variable (1 bit or 1 byte).
  •  Status feedback (1 bit or 1 byte) automatically or on read request.
  • Valve control (open/closed while deenergised) can be configured.
  • Summer or winter operation can be selected via an object.
  • Cyclical monitoring of the corrected variable; if a corrected variable telegram remains off within a monitoring period, the output switches into the emergency mode and an alarm message is sent.
  • Each output can be locked in a forced position (forced setting), and different values are possible for summer and winter operation.
  • Behaviour when the bus voltage returns and fails can be parameterised separately for each output.
  • Overload or short-circuit message can be set via an object.
  • Control of valve drives in switching operation or PWM operation.
  • Protective function against jammed valve. 


  • Free assignment of the functions switching, dimming, blind and value transmitter to the inputs.
  • Blocker for blocking individual inputs.
  • Behaviour when the bus voltage returns can be configured separately for each input.
  • Telegram rate limiting.
  • Switching function: two independent switching objects for each input present and can be enabled individually, command for rising or falling edge can be set independently (ON, OFF, CHANGE, no reaction).
  • Dimming function: single and double-surface operation, time between dimming and switching and dim-step size can be set, telegram repetition and stop-telegram transmission possible.
  • Blind function: command can be set with rising edge (no function, UP, DOWN, CHANGE), operating concept can be configured (Step - Move - Step or Move - Step), time between short and long-term operation can be set, slat adjustment time can be set.
  • Value transmitter and light scene auxiliary unit function: edge (push button as NO contact, push button as NC contact, switch) and value with edge can be configured, value adjustment with push button by pressing and holding button for value transmitters possible, light scene auxiliary unit with memory function and saving of the scene without previously calling up is possible.
