Wood fired boiler connected to Burnham boiler
I have a wood fired boiler that has a Honeywell dual aqua stat L4081B ( I use only one side) to kick on a circulator zone when the wood boiler gets too hot 220. The aqua stat is wired to a TacoSR501. Its worked fine for a few years. Recently, the circulator will not shut off even when changing the settings on the aqua stat. I can hear it click at the aqua stat but yet the circulator does not turn off. Could the problem be the relay in the Taco SR501? I would think if it was one of those fuses then my circulator would not turn on at all...but I can't get the thing to turn off??? Novice here so any helpful info would be appreciated. Thank you
