Come on, I have to set the AC to 82 for a 76.
My digital replacement is like that too. The old manual one would have a 3-4 degree swing... If I set it at 74 degrees, it would let the temp get to 78 before the AC kicked on, then would cool to 70 before it shut off. Its annoying, but tolerable for adults. We had a newborn baby trying to sleep in those conditions whose body temperature doesn't regulate nearly as well. That was unacceptable.
We bought a digital thermostat and installed that. The temp on the display is off by a lot, maybe 4 or 5 degrees, but it holds the temperature pretty steady. We have an indoor/outdoor digital thermometer, so I just dial the temperature in right and leave it alone.
I wasn't able to find any way to adjust my Coleman-Mach thermostat.
Don't forget that while you have a higher end RV, some components are the same standard components that you would find in my lower end JayFlight...
