I have a Lochinvar boiler for hydronic heating in my home. It has a Hall Effect sensor that triggers domestic hot water production when it senses hot water flow from a water tap in the house. Unfortunately, the Hall Effect sensor triggers instantly and fires up the boiler even for 1-2 seconds of water flow (such as rinsing my hands in a sink). The system assumes that even a 1 second long request for hot water means someone wants to take a shower. There is no way to program the boiler to ignore short/errant requests for hot water at a tap. I would like to insert a circuit delay that would hold off firing up the boiler for 15-30 seconds. This would limit cycling of the boiler to times when someone REALLY wants hot water delivered to a tap. I've attached a photo of the sensor. I think it's a 12v sensor. I don't have a wiring diagram. Any suggestions on how to do this?
