Has run about 20 minutes and I took the picture. About a minute after the picture was taken it shut down, still 'Heat On' showing and 3 degrees short of the goal. It started back up within a minute.
I didn't look at the basic setup yet so I still have to do that. Sorry, got lazy after wrestling trying to get the printer going with the switch I bought.
I'd be more motivated to get this straightened out if we didn't have any heat at all. I've called the electrician, hopefully they can work us in sometime today.
The furnace just shut off again as I'm typing. 'Heat On' still showing and we're at temp too. It started up again and I just heard a 'click' from it. 'Heat On' is now off, so I think it's in the cool down phase that it goes thru.
More to come...and thanks to all for helping.

Based on that, you're cycling off of limit. The Heat on indicates you've got a call for heat. The fact that it remains on when the furnace turns off tells me you're cycling off of limit. I'd call a heating contractor (well, I wouldn't because I am or was one) and have them check the system out. Make sure you check your air filter or filters before you call someone to come look at the system. I've seen some attic systems have a primary in the wall or ceiling of a home but also have one at the furnace.
Edit: One more thing. Make sure all of your supply registers are opened and none are blocked off too.
