Product details

The Vaillant room temperature controller VRK 121 is a reliable device for regulating room temperature in heating systems. It is designed for manual control and allows for precise temperature regulation in the range of 5 to 30 °C. The controller operates with a 2-point control system and is suitable for installation on the wall or in flush-mounted boxes. Equipped with a robust bimetallic sensor, it offers easy operation via a rotary mechanism. The room temperature controller is not compatible with smart home systems and does not feature a display, making it a user-friendly and straightforward solution for heating control. The IP30 protection rating ensures adequate safety for indoor use, while protection class III guarantees reliable operation. The Vaillant VRK 121 is thus a practical choice for anyone seeking a simple and effective solution for temperature regulation.
