More information

•  The flow switch acts as a safety device.
• It is a switch with an in-built sensor that sits in the pipework for both the heating and domestic hot water systems.
• When the pump is activated, the flow switches senses this movement and feeds the information back to the electronic control, allowing the ignition sequence to progress.
• The purpose of the flow switch is to make sure that the burner cannot switch on if the system is low on water or dry.
