This room temperature controller has been specifically designed for regulating or monitoring temperatures in offices, living spaces, and hotels. It is suitable for direct connection to up to 10 valve actuators (normally closed) for hot water heating systems. In normal operation, the display is deactivated. By touching a key area, the current room temperature is displayed. If a key area is touched during this display, the desired set temperature can be adjusted in 1°C increments. When the heating output is active, this is indicated in normal operation by a white dot.
