Replacement Furnace/AC Thermostat

[Max49]

I have a new 2018 Conquest 6238 CL C. It has the Dometic digital, touch to change, modes furnace, AC, high, low,and auto fan speed.
I do not like it at all. Eventually, I get the furnace turned on, and the AC fans start running, go to try to turn them on "auto" so supposively they wont run, but you have to go thru all the modes and usually I end up turning the furnace off because it come before the fan speed setting.
I guess I just would like to Kiss, keep it simple with a regular thermostat.
Also mine does'nt like to respond to touch like it is supposed to , especially in cold conditions.
Has any one else had trouble with this T Stat https://www.amazon.com/Dometic-33162...GXGG92H98HFT6C
It's new and still under warranty, but I'd like to replace it with a regular one. Can I use an analog one without having to change a circuit board?
