RTBSB-201.500
Room thermostat, surface-mounted super flat, 5…30…°C, 230V AC, NC contact, 2-wire connection
Electromechanical room thermostat in super-flat surface-mounted housing (only 13.9mm deep) for controlling or monitoring temperatures in offices, living rooms, and hotels. The thermal feedback achieves a very accurate switching differential. The setting range can be changed with the range restriction located under the setting knob. The unit is mounted by means of surface/wall mounting (4-hole fastening on the flush-mounted box).
Suitable for hot water heating systems. The device has been developed for 2-wire installation (operating and switching current input, heating output) and does not require a neutral conductor.
