Electromechanical flush-mounted room temperature controller for controlling or monitoring temperatures in offices, living rooms and hotels. In conjunction with the corresponding cover set, it fits into all common switch ranges. Matching cover set no. JZ-001.xxx. Suitable for all types of heating. 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 230 VAC (e.g. with a clock controller or timer), the temperature is regulated to a temperature that is approx. 4K lower. The color of the lower part is anthracite and the color of the upper part corresponds to the selected cover set.
