  • Wiring Honeywell T6 Pro Smart Thermostat

    Hello, I'm trying to replace my thermostat with a Honeywell T6 Pro Smart and am unsure of where to place a few of the wires. Pretty sure on the G, O, Y, R, C but would like reassurance. Definitely not sure on where the brown, black and white wires go. On the old thermostat, white goes with W1 but there is also a bridge between W1 and X2 using a white wire. This is for an existing Trane HVAC with a heat pump. Anyone have an idea what the exact wiring should be? Attached is the current wired thermostat and the new wiring ports.
