    Relay switch R8222D 1014

    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.

    Lmfao well this isnt a friendly site. Thanks for sharing the true colors of yourself. I'm sure the admin wouldn't be proud of the disrespect that it's member shows to new members looking for advice. Thanks

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

    For all... Please keep in mind...THIS IS NOT A DIY SITE. Please do not ask DIY repair instructions and expect an answer.
