Primary boiler is keystoker using oil burner secondary with setting zero on high & low. Just keeping oil burner powered for circulators for 2 zones. Coal boiler is pipe in series with circulator for loop. Will a R8222D work to get thermostat to work in conjunction to both heating sources? Right now coal boiler only runs on low side. Wiring Diagram will greatly be appreciate. Thanks

Looks like you're asking for then just help and your question is not very clear to me, one of the viewers to safely give any information. You can do a lot with a DPDT relay. How about a wiring diagram of what you have now.

Assuming that you are using 24V control you should have a relay with pilot duty contacts. Voltage rated contacts will work for a while, year or so, then start to be problematic.

To the contrary. Scroll up to the top of the page and note the yellow banner section.
