RTBSU-401.265#00

Room thermostat, flush-mounted, 24V AC/V DC, two-way contact, heating/cooling switch

Electro-mechanical flush-mounted room thermostat for controlling and monitoring of temperatures in offices, residential properties and hotels. In combination with the corresponding cover set, works with all common switch ranges. Compatible cover set no. JZ-037.xxx. Especially for 2-pipe climate systems. Heating/cooling changeover is performed using the heating/cooling switch. Thermal feedback is used to obtain a very accurate switching difference. The setting range can be adjusted using the range reducer located under the adjustment knob. Simple electric connection without screws. New terminals for quick and easy installation. Simplified wiring thanks to colour-coded terminals. The modular principle saves time: Controller, frame and cover are mounted in a practical order. Small installation volume for quick and easy mounting in flush-mounted socket. Temperature control possible even without cover. Closed design. Optimum screw seat. The colour of the lower part is anthracite and the colour of the upper part corresponds to the selected cover set.
