SOURCE: need wiring for honeywell pro 3000 in trane xe1200
the pro 300 is a single stage thermostat and can not be wired to control 2 heat stages seperately

my weathertron heat pump stopped putting out heat

OK. Here is a Trane Weathertron BAYSTAT240 thermostat wiring picture. This heat pump w/ electric (emergency) heaters is running right now. Notice the G terminal has green wire, the R terminal has red wire, the white wire is jumpered from W to X2, etc. The black wire loop you see in the center hole is unconnected.
This unit is adjusted by leveling the base - loosen the screw to the left of "R" and the one to the right of "F". Twist the base clockwise to RAISE the indicator. This makes the mercury in the switch turn ON at a different temperature. Remember to tighten those 2 screws again.
You will have to experiment several times to make the unit read exactly right. If the tech installed the base exactly level, the unit would read right (it says here).

I have it set up for electric heat pump with forced air.
106 looks like an issue with your reversing valve, "o" wire. Turn on your heat, check your condenser/outside unit and see if you have cool air blowing off the fan. This would mean your reversing valve is working and you are not just using your electric heater to heat the house. If so, double check settings and be sure its setup for heat pump with back up electric heat, reversing valve energized with "o" wire and energized while in cooling mode. If settings are right turn off main power for air handler/ inside unit and turn back on. Nest may need time to learn settings. Also i believe your black wire should be your aux wire. I cant see the top pic to well to see what the brown wire is attached to. Good luck.
The outside fan is not running just making a buzzing noise is that something to do with the wiring? The brown wire goes to R
I put the black wire in the aux spot and now the fan outside is blowing cold air. Hopefully I don't get another error code. Thanks for your help
Turn off main breaker for air handler. On the nest put red to rh, green to g, white to w, orange to o, yellow to y, blue to c and black to aux. Cap other wires and do not use. Turn on the breaker. In settings you should have, heat pump with backup electric heat, "O" controls the reversing valve and the reversing valve is energized while in cooling mode. That should do it. If that dont clear the code look through manual on how to clear codes off stat. Good Luck.
Jennifer, did you ever get this straight?? I have the same exact setup as you and im struggling haha
