Hi,

Yes, I need to know which wiring terminals that you have wires on, on the new thermostat. This is usually an easy fix.

Thanks

Mark,
I got the heat working last night. When using the heat pump markings, the White was connected to the AUX. I moved it over to the O/B terminal. I did have the blue wire there. So now, where in the heck does the blue wire go? By the way, I examined the wiring inside the unit and the blue wire goes right to the outside unit. The white connects to W/BK and W/BL and W on the inside unit.

Brown is the common
Yellow to Yellow
Green to Green
Red to Red

Not using Orange

Mark,
Yes, I believe that this is a heat pump. It appears that the BL and Y wires run directly from the tstat out to the outside unit. All other wires (BR, G, W, and R) go to the inside unit (some of them may also run to the outside as well). Let me know if you need me to take the cover off and check to see what runs where.

Thanks!

Yes if you can somehow find out how many wires are connected outside it would help me out,

Thanks
