No longer a newbie, but still clueless.
More deets please.
Both companies have pages on their sites dedicated to compatibility checks, based on your current wiring. You basically select the wires that you have in your current panel, and it comes back with an answer. Normally, your therm has multiple colored wires going into it. While the wire in my wall contains all those different colors, the only ones used are the black and the red. I suspect it has something to do with my furnace/air handler handling some of the 'logic' that those other wires would control in other systems - or the therm helps it do that. But it seems to me that my system and therm are kinda made to work with each other. Anyway, mine looks like the pic below. You can send pics to Ecobee for further details/analysis, which I've done. I'll see if they say anything different.
