Just moved into a new house and I'm trying to wire an Ecobee 3. I pulled off an old Honeywell Lyric T5 “smart” thermostat and noticed that there was no Ground wire
This is how i wired my Honeywell Lyric T5. It operates the heat just fine. But it doesn't work the AC. What am i doing wrong? : r/honeywell
Old thermostat works, but I can't get the Honeywell T9 to work. T9 require C Wire that was not in the wall. I added C wire & RC wire via plug-in 120v
