Room thermostat, surface-mounted super flat, 5…30…°C, 24V AC, 2(1)A, NC contact, ECO function

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. Connecting the ECO input with 24V AC leads to an approx. 3 K lower adjusted temperature (night-time reduction).
