Made in Germany
since 1969
We have been designing and manufacturing thermostats in Berlin since 1969.
Not as a lifestyle product, but as an integral part of building technology. Our solutions are designed to operate reliably for years, both during installation and in daily use. We believe in straightforward systems, clean technology, and products that are easy to understand.
Designed for professionals.
Our products are born out of real-world experience. Electricians and designers use our devices every day for design, installation, and maintenance.
Their needs drive our development: clear functionality, straightforward technology, and the ability to integrate with third-party systems combine to deliver reliability and flexibility.
At the same time, our thermostats are used daily by people who don’t want to deal with technical details. We take that into account as well. A good product must deliver on both fronts.
Function and Form
We believe that the more understated the thermostat, the better. The housing, controls, and displays are designed to make a presence in the room without being overpowering. Clean lines, smooth surfaces, and easy-to-read displays ensure that our devices blend seamlessly into a variety of settings, from residential homes to commercial spaces. For
us, design is not an afterthought, but an integral part of product quality.
Focus on
the essentials
Control technology doesn’t need fleeting trends. It needs stability.
That’s why we focus on:
- proven regulatory frameworks
- Wide compatibility with all heating systems and standard switch plates
- product families with long-term availability
- User interface designs that are clear and intuitive
We omit anything that does not contribute to functionality or clarity.
Development,
Design, and
Support, in Berlin
Our development, product design, manufacturing, and technical support teams work closely together. This results in products that are technically sound and, at the same time, perform reliably in everyday use—both in installation and operation.
Feedback from real-world use is directly incorporated into further development.
Responsibility for
the product lifecycle
Thermostats are part of a building’s infrastructure. They remain in use for many years. We take our responsibility seriously:
- long-term product availability
- Consistent designs across generations
- clear documentation
- Support is also available for existing installations
Our goal is to provide durable technology that never goes out of style.
Our customers
Our customers include electrical contractors, designers, and system integrators. They value our products for their straightforward technology, reliable documentation, and solutions that are easy to plan and install. Our thermostats
are used in residential construction and renovation projects because they are available long-term, have a discreet design, and function reliably for years.
