I hope you have the Visionpro TH8320 or the TH8321. The TH8110 is not compatible with your multistage heat pump.

New terminal = wire
G = green
O/B = orange
E = black
C = blue
Aux = white (you can jumper this to E to match the old setup)
Rc & R = red
Y = yellow
Tape off your brown wire. Your new thermostat does not require an outdoor thermister for proper operation.

You must also configure this stat to match your system.
option 170 = 7
option 190 = 0
option 240 = 9 if you have electric auxillary heat
