The thermostat calls for heat the boiler fires up and the hot water circulates. the problem happens when as the hot boiler cools off and reaches the low end temp when it signals the burners to relight; it relights for a moment and then immediately turns off.
I thought of a snubber, but the short cycling isn't "hunting", The boiler will fire and I can watch the pressure (on a 20 oz gauge at the vaporstat) rise to 8 oz over about a minute, then it shuts off, and it takes another minute or two for it to drop back down to the 2 oz lower setpoint. I think a snubber would only stretch that out a little.
My problem is excessive short cycling of the oil burner resulting from interfacing a single circulator, 5 zone valve hydronic heating system through a Taco ZVC 405 controller with an MH L8124A aquastat.
