RTBSU-401.262#00
Room thermostat, flush-mounted, 24V AC/V DC, NC contact, heating display, on/off switch, night-time reduction
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-035.xxx. Suitable for water-based heating systems. The heating process is indicated by a light. The device has an ON/OFF 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. Connecting the ECO terminal with 24 V AC/V DC (e.g. using clock controller or time switch clock) leads to an approx. 4K lower adjusted temperature. 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.
