NEW: tamper protection for eTR series push buttons

News of 03 April 2025

New housing design with screw protects against unauthorised access

Our popular glass push-buttons from the eTR series have been given a practical new feature: from now on, we are equipping all models in the series with a locking screw that makes it more difficult to remove them from the wall and thus protects against unauthorised tampering. Ideal for public buildings and high-traffic areas!

Installation and removal of the new models will only be possible with a tool (screwdriver). 

The appearance, range of functions and ETS application will of course remain unchanged – only the installation depth will increase by approx. 0.5 mm to 12.5 mm.

As part of this housing change, we are offering you the unique opportunity to purchase all previous models in the eTR series with a 20 % discount on the RRP. Take advantage of this unique opportunity and secure the previous models now – only while stocks last!

What is changing?

  • Locking screw for all models
    From now on, all devices of the eTR series – both KNX and Modbus variants – will be equipped with a locking screw on the underside of the housing.
  • Tool required for assembly and disassembly
    The screw means that removing or mounting the glass push-buttons is only possible with a screwdriver.
  • More protection against unauthorised access
    This measure increases protection against unauthorised manipulation – particularly useful in schools, public buildings or freely accessible areas.
  • Slightly modified design
    The new design results in a slight increase in the mounting depth – instead of approx. 12 mm previously, it will be approx. 12.5 mm in future.
  • Function & appearance remain the same
    The devices continue to look the same and retain their full range of functions. The ETS application also remains unchanged.
  • Change to the item number
    The new devices with screw have a new item number. The previous models are being sold out and will no longer be available.

About the KNX eTR series

The KNX eTR series combines atractive design with intelligent functionality and flexible installation. Whether installed with or without a switch box, the controllers and push-buttons can be adapted to a wide range of structural conditions. The elegant real glass surface in deep black (RAL 9005) or signal white (RAL 9003) blends harmoniously into modern interior design styles and ensures a high-quality, timeless look.

In addition to its elegant appearance, the eTR series also scores in technical terms: a temperature sensor integrated into all devices enables precise room temperature control. Configuration is done conveniently via ETS – without the need for additional software or complicated commissioning. The result: maximum comfort with minimum effort.
