Could someone tell me how to wire these together?

I have an Trane XL80 2 stage & heat pump with a wiring terminal labeled:

W2 W1 R G B/C Y BK/TWIN

The Honeywell Pro2000 thermostat (TH2210D) is a 2H1C model with terminals labeled:

R C Y G O/B Aux/E

The Honeywell TH2210D manual also shows:

Y - compressor
G - fan
O/B - reversing valve
Aux/E - auxiliary heat
