Flow switch De Dietrich 7677274

A flow switch is an essential safety and control device in heating systems, detecting the movement of water or other fluids. It ensures that the burner or pump only operates when there is adequate flow, preventing dry firing or overheating. This flow switch is suitable for use in boilers, central heating systems, and domestic hot water applications. It can be used to interlock the burner with the circulation pump, providing an extra layer of protection. When replacing a faulty flow switch, it is important to choose a model with the correct set point and connection type for your system.
