Is there a resolution to this problem or do I just have to live with it?

BH can you try going to 2 and then zero to see what difference this makes.  sounds like a spread to keep the cycling on and off to a minimum.  Maybe with that understanding you can live without a true fix if there is none.

Yes, it is generally called hysteresis, and for example, in air conditioning systems can be as wide as 4 degrees, 3 degrees normally about minimum around the controlling parameter, and is used to protect "short cycling" or rapid cycling of freon systems, the firing of the capacitor on the compressor, etc.  I was actually surprised to hear how tight the Nyle hysteresis band is, and I the grand scheme of things, in the real world it is set wider, and is there to protect the mechanical system.   
YellowHammerisms:

Take steps to save steps.

If it won't roll, its not a log; it's still a tree.  Sawmills cut logs, not trees.

Kiln drying wood: When the cookies are burned, they're burned, and you can't fix them.

Sawing is fun for the first couple million boards.

I am seeing a hysteresis on my unit that is even tighter than what K-guy is saying that it should be based on my settings.  I wonder if others have seen this or is it just my one unit.

You can change it if you want, the instructions are in the manual. The factory setting are our suggestion on what we think is best.

I have it set at the factory settings, but the problem is that my unit does not function the same as what you told me in reply #23.  From your reply #23, I should be seeing this:

Wet bulb setting = 101F
HyCompressor parameter setting = 1F
Compressor turns on at 103F
Compressor turns off at 101F

But below is what I am seeing:

Wet bulb setting = 101F
HyCompressor parameter setting = 1F
Compressor turns on at 103F
Compressor turns off at 102F

I am just wanting to understand why my unit turns off the compressor at 102F instead of 101F?
