The problem
I just had to replace a GE/Jasco 14287 model fan control and I ended up with a 14314 model. Both the 14287 model and 14314 model support only 3 speeds, but the 14314 currently allows any percentage from 0-100% to be set in the UI while the 14287 model will "normalize" any input to the 32, 66, or 99 value that corresponds to low/med/hi. I don't have the technical ability to create a pull request, but it appears the 14287 model received a fix for this exact issue in November 2021: #60517. I tested with my 14314 fan and the 32, 66, and 99 speeds are correct for low, medium, and high.
