The Alre-it Room Temperature Controller RTBSU-401.000#21 is an electromechanical flush-mounted room temperature controller designed for regulating or monitoring temperatures in offices, living spaces, and hotels. It is suitable for all types of heating systems. The thermal feedback ensures a very precise switching differential. The range limitation located under the adjustment knob allows for modification of the adjustment range. VDE tested.

The electrical connection is made simply without screws. New terminals enable easy and quick installation. Wiring is simplified through color coding of the terminals. The modular principle saves time: practical sequence for mounting the controller, frame, and cover. The compact installation volume ensures comfortable and fast mounting in the flush-mounted box. Temperature control is possible even without the cover. The closed design and optimal screw retention complete the product.
