I took a garden-variety Aprilaire humidity sensing unit
(call it what you want, I'll call it a humidistat), rewired it to
'make' on humidity rise, wired it in series to my setback
thermostat. Welcome to read my comments from 2 or 3 years
ago if you know how to do a proper Google search.
I believe I also mentioned that my utility bill went down, too.

MB It makes the A/C unit function as a whole-house dehumidifier. Makes

MB During the night, the humidity can get down to being drier than in
MB the Sahara Desert, and people wake up with dry throat, dry eyes,
MB etc. The humidistat cuts that out. After all, you can have a
MB comfortable 83 degrees, or a very muggy 75 degrees. The humidity
MB is the primary factor, in spite of thermostats controlling
MB most A/C units.


MB Can you tell that I've installed one on my unit?

Nope. what you are trying to do takes a lot more than a "dehumidistat"
a humidistat is for humidifiing only, or if you have the proper equipment
it
can slow the fan down to dehumidify the air more during cooling.
Those HUM terminals are for a humidifier
