Intelligent control engineering since 1989.

The Technische Alternative develops and produces intelligent controllers for heating and building technology. Especially our freely programmable x2-tech series, consisting of universal controllers and different extension modules Erweiterungsmodulen, make us popular even beyond the german-speaking area. Suitable for just about scenario, our controllers are flexible, updateable and expandable, offering a range of devices for all your current and future projects.

At this point, it's not just controllers with fitting accessories, sensors and operating units that we have to offer, but also domestic hot water stations and an electronic heating rod to make use of excess PV energy.

Professional support and affordable repairs

We help our customers to answer questions and solve problems regarding our devices using tech support via telephone. This often makes sending the device in for repairs obsolete. In any case, we still offer affordable repairs. We repair even 30 year old controllers, as long as it's possible and it still makes sense, since we practice responsible handling of ressources. With affordable flat charges for repairs and short processing times we form a good basis for this.
