Probably the flattest controller in the world

RTBSB (Berlin 1000)

The electro-mechanical room thermostat in the modern Berlin 1000 design is instantly recognisable by its super-flat surface-mounted housing (just 13.9 mm deep) and is used for targeted and highly accurate control or monitoring of temperatures in offices, residential properties and hotels. Various variants are available, e.g. with ON/OFF switch or heating display.

Basic mechanical room temperature controller


Our mechanical room temperature controller RTBSU for control or monitoring of temperatures in closed, dry spaces is suitable for all heating systems. It has a small installation volume and is compatible with all common switch ranges from various manufacturers, allowing it to be used individually.
