@CMD-Ky which one do you have? I've looked at new ones until I'm cross-eyed.
It is a Trane that came with the installation and I don't know much about it. It is a very simple electronic thermostat. It has very limited programing ability, one speed fan. I can change its sensitivity and that is about it. I set it Winter and Summer on one temperature (72 Winter and 77 Summer) and leave it alone. We have a lot of leafy trees, shad for Summer and sun for Winter) so our electrick bills are not bad. If I get another, I will pay more attention to the visibility of the screen, I need a magnifying glass, literally, to see what I am doing with it and my eyes, that having looked at the world for seventy-four years, are still rather good.
