Electromechanical room temperature controller in a surface-mounted housing for controlling or monitoring temperatures in offices, living rooms and hotels. Suitable for all types of heating. The controller has an internal setpoint setting. This makes it particularly suitable for installation in authorities, banks, schools, kindergartens, museums and similar buildings in which setpoint adjustment by unauthorized persons should be prevented. The thermal feedback achieves a very precise switching difference. The setting range can be changed using the range restriction located under the setting knob. The device is suitable for an operating and switching voltage of 230VAC or 24VAC.
