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 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.
