Electromechanical room temperature controller in a surface-mounted housing for controlling or monitoring temperatures in offices, living rooms and hotels. Suitable for hot water heating systems. The thermal feedback achieves a very precise switching difference. The setting range can be changed using the range restriction located under the setting knob. When the ECO terminal is connected to 24 VAC (e.g. with a clock controller or timer), the temperature is regulated to a temperature that is approx. 4K lower.
