Room thermostat, surface-mounted, 5…30…°C, 24V AC, NC contact, ECO function

Electro-mechanical room thermostat in surface-mounted housing for controlling and monitoring temperatures in offices, residential properties and hotels. Suitable for hot water heating systems. 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 (e.g. using clock controller or time switch clock) leads to an approx. 4K lower adjusted temperature.
