Changing Out Honeywell Thermostat

I would like to replace my old Honeywell thermostat T8411R with a new Honeywell thermostat TH8320U. I have a Trane Heat Pump Model TWNO42C and a Trane air handler TWEO42C14FCO. There are 6 wires going to the old thermostat. They go to: G,C,R,W1,O and W2. In addition, W2 and E are jumped.


OLD NEW
G
C
R
W1
O
W2
Old Jump: W2&E New Jump:


Any assistance you can provide in wiring my new thermostat and providing the correct Setup Functions would be greatly appreciated.

Do you have extra unused wires?

How many KW is your back up heat?
