This part detects if water is moving through the Chaffoteaux boiler. If these switches are detecting water flow they can either be a pump proving flow switches or a domestic hot water flow switch which detects if a hot tap has been opened. All these Chaffoteaux flow switches send signals to the printed circuit board within the boiler ensuring they are being monitored all of the time.
