Flush-mounted room thermostat, 230 VAC, NC contact, display/switch for additional heating, 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. Fits perfectly into many switch ranges without an intermediate frame. Suitable for all types of heating. The switch can be used to switch an additional heater. A red lamp indicates that additional heating has been switched on. The total current (heating + additional heating) must not exceed 10 (4) A. The total power (heating + additional heating) must not exceed 2300 W. A very precise switching differential is achieved through thermal feedback. 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.
