Wiring New Thermostat

I have a new Honeywell Focus PRO 5110 thermostat.

The wiring choices are Rc R Y C W G

The wires used on my old thermostat are G R E O W2 C Y
It's a heat pump system with Em. heat.

I can't seem to find in the instructions how to handle the wiring differences and Honeywell says that I have to have a licensed contractor to install it when I call them.

Can anyone tell me how to wire it up or can it not be done with this model?

Thanks

I may be wrong but your new stat appears to be for conventional a/c and heating not for a heat pump like your old one.

Matt is right, that t-stat won't work.. it's heat and cool on a single stage system.

You want TH6220 model.
