Question Dou Therm Thermostat Furnace Question

Hello, we recently purchased a used 2007 Cardinal 30LE. We just sold our home in RI, and will be traveling extensively across the great USA this fall, eventually ending up in Colorado. Of course, the unit did not come with any manuals, and last night we tried to use the furnace, as it's a little chilly in Weedsport, NY.

When I switched the thermostat from cool to furnace with the fan set to auto, then raised the temp. slider up, the a/c fan started immediately blowing cool air from the roof vents. This seemed strange, but I thought maybe the a/c also had a heat pump. I then checked the model # of the A/C (59516.336 Quick Cool) and it does not appear to be a heat pump unit. Anyway, the furnace never fired, and nothing ever came out of the floor vents. What am I missing here? Any help would be appreciated, I'm an RV newby.

I had the same problem a couple of years ago on my previous tv. Problem was a bad circuit board in the wall thermostat. I installed
a new one for about 50$ and had heat. Good traveling.
