My first modification to our new Flagstaff 831KRSS was installing the Hunter digital thermostat (Model 4299B). I followed these great instructions
I found on google. I could not find the author name, but wanted to give him credit. The entire project took about 1 hour with some minor soldering required. Cost of project was about 30-35 bucks depending on what stuff you have lying around.
This mod works great... it keeps the temperature within 1 degree of where it is set. You will notice the addition of a rocker switch under the thermostat, this allows for a low/high fan speed, instead of just having auto and on for the fan. Most homes don't have low and high on the AC fan like RV's, so not wanting to give up this option, I installed the extra switch.
If anyone has questions on this please email me anytime. Frank
