RTBSB-001.910/2
Room thermostat, surface-mounted, 5…30…°C, 24V AC, two-way contact, ECO function, internal setting
Electro-mechanical room thermostat in surface-mounted housing for controlling and monitoring temperatures in offices, residential properties and hotels. The controller has an internal setpoint adjustment. This makes it ideal for installation in administrative buildings, banks, schools, nurseries, museums and similar buildings where unauthorised people are to be prevented from adjusting the setpoint. 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.
