I have a two wire furnace. I’ve been doing a lot of research but haven’t found anything super similar to what I have at my house. I’m trying to find where to connect the c-wire. I have a couple of extra unused wires so I think I can just connect that to the c-terminal but I’m not 100% sure which one that is.
Based on my research it looks like maybe I could connect my Ecobee to the bottom 25V terminal?
Your help is incredibly appreciated in advanced!
