Flush-mounted room thermostat, 230 VAC, NC contact, 3000W, alre frame, cover 50 x 50 mm, pure white, glossy
Electromechanical flush-mounted room thermostat for controlling or monitoring temperatures in offices, living rooms and hotels. Particularly suitable for high-power electric heating systems. The thermal feedback achieves a very precise switching differential (do not connect terminal N for heating outputs greater than 1500 W). The setting range can be changed using the range restriction located under the setting knob. Simple electrical connection without screws. New terminals for quick and easy installation. Simplified wiring thanks to color coding of the terminals. Time-saving thanks to modular design: practical assembly sequence of controller, frame and cover. Small installation volume for convenient and quick installation in the flush-mounted box. Temperature control already possible without cover. Closed design. Optimum screw mounting.
