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.

Garantie légale

Avis harmonisé de l'UE sur la garantie légale

Protection offerte par la garantie légale minimale de deux ans sur des biens vendus dans l'Union européenne.

Les consommateurs peuvent faire valoir leurs droits au titre de la garantie légale de conformité, par exemple si les biens:

  • ne correspondent pas à la description;
  • ne fonctionnent pas comme prévu.

Les vendeurs sont responsables de tout défaut de conformité qui existait au moment de la livraison des biens et qui apparaît pendant la période de garantie légale. Les vendeurs se trouvant dans une telle situation sont tenus de proposer:

  • une réparation gratuite ou un remplacement gratuit;
  • dans certains cas, une réduction de prix ou un remboursement intégral.

Dans certains pays, la période de garantie légale est plus longue. Pour les biens d'occasion, une période plus courte peut s'appliquer, mais elle ne peut être inférieure à un an.

Que faire si vous recevez des biens non conformes:

  1. contactez le vendeur dès que possible pour signaler le problème;
  2. fournissez une preuve d'achat, telle qu'un reçu, une facture ou un relevé bancaire.

Les vendeurs et les producteurs peuvent également offrir des garanties commerciales, qui s'appliquent indépendamment de la garantie légale. Par exemple, il se peut que votre bien affiche ce label GARAN, représentant une garantie commerciale de durabilité offerte par le producteur sans frais supplémentaires et s'appliquant à l'ensemble du bien.

Pour en savoir plus sur vos droits dans un pays donné, consultez la page ci-dessous ou demandez au vendeur. https://europa.eu/youreurope/garanties
