Programmable Thermostat Heatpump

I have a Trane 2 stage gas furnace-electric heatpump. I purchased a Hunter 2 stage programmable thermostat but the wiring codes do not match up. The original Trane has wires on: X2,O,G,Y,T,R,W,B. The Hunter uses R,Y1,W1,W2,G,O/B,E, A, C. I've figured out the logical ones but I can't figure out the X2, T, or the O and B on the Trane. Anyone have thoughts on where they should connect on the Hunter?
