RTBSB-001.910/2
Room thermostat, surface-mounted, 5…30 °C, 24 VAC, changeover contact, ECO function, indoor setting
Electromechanical room thermostat in a surface-mounted housing for controlling or monitoring temperatures in offices, living rooms and hotels. The controller has an internal setpoint adjustment. This makes it particularly suitable for installation in public authorities, banks, schools, kindergartens, museums and similar buildings where setpoint adjustment by unauthorized persons is to be prevented. The thermal feedback ensures a very precise switching differential. The setting range can be changed using the range restriction located under the setting knob. When the ECO terminal is connected to 24 VAC (e.g. with a clock controller or time switch), the temperature is regulated to approx. 4 K lower.
