So attached is a photo of the current wiring that is for my full Trane System. I currently have a XL824 thermostat hooked up, but the WiFi is going so I'm looking to install a new thermostat. However, the wiring doesn't seem to match up with anything I have found for the Nest. This would be on a gas furnace with multispeed fan as well as the A/C component.
thoughts?
