it turned cool here to day so decided to turn the heat on. I noticed that no heat comes out till temp is set to 80. Is there any adjustment to allow heat to start flowing at a lower temp?

Two years later - still no adjustment. Think of it as a sundial and accept it for what it is - hardly precision!!!

Don't know, but when it's in the 20s outside we get plenty of heat when it's set to 70.

Is the diverter door working, as well as the thermistor located on the plenum in the passenger footwell? Just noticed you are in Florida - how cold is it? If there's not enough differential between inside and outside temps you won't get a lot of heat.
