Room thermostat, surface-mounted, super-flat, 5…30 °C, 230 VAC, NC contact, 2-wire connection
Electromechanical room thermostat in a super-flat surface-mounted housing (only 13.9 mm deep) for controlling or monitoring temperatures in offices, living rooms and hotels. 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. The device is installed by means of surface/wall mounting (4-hole mounting on flush-mounted box).
Suitable for hot water heating systems. The device was developed for a 2-wire installation (operating and switching voltage input, heating output) and does not require a neutral conductor.
