Oil fired boiler need help with
I have installed a hydronic heat exchanger in my existing electric forced air furnace plenium which will be heated via an oil fired boiler. Where I'm running into trouble is how to energize the fan from the electric furnace when the boiler is called for heat in this zone.
I also have a liquid to liquid heat exchange for the outside shop , this zone is using two grundfoss circulation pumps, how do I wire these to come on simultaneously when heat is called for. I have been told to run the shop side pump contiously, but would rather not.
What are my options using the Taco SR504 zone relay.
