On a single stage system it's going to be harder to set the humidity since the system only runs at 100% or Off. With a variable speed system or even a two stage system, you will have better control of the humidity because the system runs longer and slower. My variable speed system sometimes goes into Dehumidifing mode which is running at a very low speed specifically to lower the humidity.

To clarify, most HVAC systems in The Villages do not have the capability to "increase" the humidity in your house. This requires a humidifier that actually sprays water into your duct. What you do have is an optional humidity setting on your thermostat that can "reduce" the relative humidity by increasing the cooling time or by overcooling your house to a few degrees below the temperature setting. Even today, when it is raining, my thermostat is set on 79 degrees, the optional humidity feature is turned off, and the relative humidity in my house is a comfortable 43 percent. It seems to me that if you need to set your humidity setting to 55 or 60 percent, you must be leaving a door or window open, or you are adding outside air into your house. The relative humidity in my house never gets that high.
