Thermostat wiring issues
Im replacing a Honeywell T8411R with a Honeywell vision pro TH8110
The wiring part is confusing me maybe someone can explain. I dont understand where the White wire or the green wire with the black mark on it goes. See pics

You have the wrong stat. The TH8320 and Th8321 will support your multistage heat pump.
When you get the correct stat...
G = green
C = blue
Aux and E = green/black
Rc & R = red
Y = yellow
O/B = white
You must also configure this stat to match your system.
option 170 = 7
190 = 0
