Flush-mounted room thermostat, 24 VAC/VDC, changeover contact, heating/cooling switch
Electromechanical flush-mounted room thermostat for controlling or monitoring temperatures in offices, living rooms and hotels. In conjunction with the corresponding cover set, suitable for all standard switch ranges. Matching cover set no. JZ-037.xxx. Especially for 2-pipe air conditioning systems. The heating/cooling changeover takes place with the heating/cooling switch. 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. The color of the lower part is anthracite and the color of the upper part corresponds to the selected cover set.
