All, I am trying to upgrade my Thermostat and am very confused how to connect the wires correctly (Florida house built 1991, AC and heat strips, no furnace): As is, Trane XT500
- Blue to B
- Red to R
- White to W
- Green to G
- Tan to O (I think this is supposed to be Orange)
- Yellow to Y1
- Jumper W to X2
On the Honeywell:
There is B/O not B and O as separate connections. There is no W. There is no X2.
Available Connections are:
Here is the Honeywell Replacement (VisionPro 8000 TB8220U1003): As you can see we ran the wires from what seemed obvious/reasonable, but didn't know what to do with the white wire. Also, we connected the Blue and Orange (tan) wires together into the O/B slot. Don't know if that is good or bad.
