I disconnected my previously working ecobee to go back to traditional non WiFi Honeywell thermostat that was installed before the ecobee3.
The Heat works good but when I try to turn on AC it just won’t kick on. Thinking I connected the, back incorrectly, can’t seem to figure it out. I attached an image of my thermostat wiring and furnace wiring.
The AC common wire (white) is going to T terminal since I don’t have a C. The AC Y (Red) wire is going to the Y terminal.
Any advice it tips would be greatly appreciated.
