A Swiss companyWith long history and tradition.

Since 1967 we have been focusing on control technology and building automation. At that time the company started as a family owned business in the centre of the city of Chur and developed and manufactured control and monitoring devices for oil boilers. The company grew steadily and established itself among boiler manufacturers throughout Europe as a reliable and innovative supplier of electronic heating controllers.

Today the company consists of several locations and employs over 100 people in Switzerland, Germany and Hungary. We offer complete solutions in the field of control technology for HVAC applications, as well as free programmable controllers for intelligent building automation systems and a full range for smart home applications. All products are represented in the market both as proprietary products and as so-called OEM versions.
