Ok great! There are many models in the Honeywell 8000 series line but I will give the typical wiring for an 8000.... Bear with me while I type it all out please :)

This is how you will wire the old Trane thermostat to the new Honeywell:

Old thermostat terminal > New thermostat terminal

R > R and leave jumper to Rh

B > C this is 24 volt common and Trane calls it B while all other manufacturers call it C

G > G

O > O/B

Y > Y or Y1 (whichever it has)

W > Aux/E (jumper between Aux and E if they are separate terminals)

T > unused, tape end and tuck back in the wall

You will need to go into the installer set up and tell the thermostat that you have a "heat pump WITH auxiliary heat"

All other installer set up options should be ok at their default.

Very good, let me know how it turns out when you return. Make sure you turn power off to your air handler before beginning the wiring changes!
