Electromechanical flush-mounted room temperature controller for regulating or monitoring temperatures in offices, living spaces, and hotels. Compatible with all common switch programs when used with the appropriate cover set. Suitable cover set number: JZ-035.xxx. Suitable for all types of heating. The heating process is indicated by a lamp. The device features an on/off switch. A very precise switching differential is achieved through thermal feedback. The adjustment range can be modified using the range limitation located under the adjustment knob. When the ECO terminal is connected to 230 VAC, for example with a timer or programmable switch, the temperature is regulated to approximately 4 K lower. VDE tested. Simple electrical connection without screws. New terminals for easy and quick installation. Simplified wiring through color coding of the terminals. Time savings due to modular design: practical sequence of mounting the controller, frame, and cover. Compact installation volume for comfortable and quick mounting in the flush-mounted box. Temperature regulation is possible even without the cover. Closed design. Optimal screw retention. The color of the lower part is anthracite, and the color of the upper part corresponds to the chosen cover set.
