It will run the A/C to dehumidify your house.
It will make your house cooler to do this. Up to 3°.
52% isn't bad.
If you don't have a VS blower, I woouldn't set humidity any lower then 50%.
I noticed that the "Indoor Dehumidification Control" is not activated on my TH8321 Vision Pro. What happens if I activate it? How does it work when activated? What are the ideal indoor humidity levels? Presently the stat reads that my indoor humidity is 52%.

I do have a VS blower on the furnace. I guess the humidity setting on the stat would want to run the compressor on first stage for longer periods with the fan speed at slower levels. Does the stat control the fan speed or does the furnace board? Does the stat simply give up after awhile? For example, if I set the humidity at 40% (not that I intend to), does the stat just give up once the inside temp is 3 degrees below the temp set point, notwithstanding whether it has hit the humidity set point? In the winter how does it react to a call to raise the humidity?
The VP does not control the blower speed. it turns on cooling, and yes, it will only cool down 3 degrees less, and shut off.
Thanks you for the responses.
Sounds like the VP humidity control doesn't offer much difference from simply lowering the temp set point on the stat.
But in the winter how does the VP react to a call to raise the humidity? Also, FYI I have a duel fuel, heat pump if that makes any difference.
No, it's said that Honeywell didn't make this works like it really should. :-(
It will only work on Cool mode, won't affect heating.
Well, that being the case I think I'll just leave it off. (Also, the humidity has dropped to 50%, not bad for a rainy day in Ga I guess).
Seems like the humidity control concept isn't bad, but to be implemented correctly the stat would have to control the VS blower, and ideally hold off going to the second stage compressor for as long as possible. Although the VP may be doing the best it can in regard to the compressor because it doesn't move to 2nd stage until 1st stage is running at 90% capacity. However, I suspect the VP's 90% capacity determination is based on software assumptions as opposed to electrical load measurements, and accordingly could and should be altered for humidity control.
