ANDREWS C831 HI-TEMP FLOW SWITCH R2000-R18.
The flow switch acts as a safety device that has an inbuilt sensor which sits in the pipework for both the heating and domestic hot water systems. The flow switch is designed so that it can detect movement in the pipework and feeds the information to the printed circuit board (PCB) which then allows the ignition sequence to progress. The purpose of the flow switch is making sure there is enough water in the system and prevents the burner from activating if the system is low on water.
