Welcome
From heating control, solar, cooling circuit and ventilation control to entire building automation and energy management: Building automation done right.
Eletronically regulated Domestic Hot Water stations
In addition to our controllers, we also offer solutions for DHW preparation. DHW stations warm water only once it's needed. That saves both energy and space. The new FRISTAR2WP is, with its very low inclination, intended for very low temperatures, as heat pumps for example bring them.
Optimize PV usage the smart way
ATON is a plug & play solution for usage of excess PV power - without additional wiring. Connected wireless via CORA, the energy meter transmits the amount of power to be used to the immersion heater.
Due to the freely programmable energy meter CAN-EZ3, inidvidual needs like the integration of heat pumps or further consumers, can be realized too.
Programming example: Excess power charging
Our latest example shows how to use a charging station with our CAN-EZ3 smart meter. Details in the video (german language).

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.
