Wow. How did I have it completely backwards?

Just lucky, I guess.

The previous settings were operating your air conditioner instead of the furnace. They are for a heat pump system.

So, even though it is a single stage system, it is still considered conventional?

Yes. Is it operating correctly now?

At first, I thought nothing was happening. But, it is definatley blowing hot air now. But, the outside thing (condensor?) is not running. Is that OK?

Absolutely. It should only operate in cooling mode. Enjoy the warmth.

KC13, thank you so much. I have spent so much time working on this, and you are absolutely amazing. THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU.

Your comfort is my reward...

How do I give you reputation points, or otherwise express my gratitude?

Click on "Rate answer".

Only my posts have that option -- not yours, and when I click it on my post,

" This post has not received any reputation. You currently have 1 reputation point(s).
"

If you have an area of expertise, use it to give back to AMHD. That is the best gratitude...

See?

How did you do that?

I hit "print screen" on my keyboard (near the numlock, page lock buttons), opened mspaint, pasted, cut out the irrelevant parts, saved, and then uploaded it here.

I think we've found your area of expertise... while I'm savvy when it comes to HVAC, 'puters are another thing. Don't worry about the rep, I get my share.
