He said if the new thermostat had terminals, he could figure it out.
But now if this isn't going to work, he wants to hook up the old thermostat back up. But it's not cooperating because of the lose of communication of the thermostat and it keeps flashing the e1. How can we resolve this problem of the e1 flashing
What you have is a Master stat with the 6 wires, and a secondary stat with 3 then. If you want to separate the two units the, you will need to add a wire to the 3 one (pull another wire) and use 4 wires for each stat. It's hard to tell you how to do it the other way. You would need to reinstall the original stats. What are the original Stats? Who made them? I could see if I could look it on-line for you. Without knowing that I can't advise, some stats will not work. You should have gotten a service manual with them and that should tell you what the error code is. That would be helpful information. You also need to look at the circuit board at the AC in the R/A. and see if you have 4 terminals on it R,Y,G,with a C or B also.
