Replacing a Simplecomfot Tstat with Honeywell wiring


I am replacing a SimpleComfort 2200 with a Honeywell RTH3100C and need help with the wiring.

Here is a picture of the SimpleComfort unit:

And here is the connector for the Honeywell:


Can anyone help with the wiring? It's cold out baby!

Thanks!
Tom

Replacing a Simplecomfot Tstat with Honeywell wiring


R-24 volts (red wire)
O-reversing valve for heat pump (brown wire)
C-common (blue)
G-fan (green wire)
Y1-Cool (yellow wire, will go to Y on new stat)

All the above will be like for like.

W2-heat (will go to aux on new stat)

Turn the breaker to the furnace off first as you stand the chance of blowing a fuse, transformer or possibly the board.
