RTBSU-401.052#21
Room thermostat, flush-mounted, 230V AC, NC contact, additional heating display/switch, alre frame, cover 50x50mm, pure white, gloss
Electro-mechanical flush-mounted room thermostat for controlling and monitoring of temperatures in offices, residential properties and hotels. Provides a perfect visual match in many switch ranges without any intermediate frames. Suitable for all types of heating. Additional heating can be switched on using a switch. A red light indicates when additional heating has been activated. The total current (heating + additional heating) must not exceed 10 (4) A. The total output (heating + additional heating) must not exceed 2300 W. 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.
