I read that if you set the T-stat to 70º and the H-stat to what you
*perceive* to be a comfort level, the AC only runs to achieve the relative
humidity set on the H-stat. It went on to say that it helps to keep the unit
from cycling as often as it normally would, thereby saving electricity and
still be comfortable. The THI here for a week has been 110 - 115, and it
just got me to wondering. As inexpensive as the H-stats are I thought it
would be worth a try - or at least the time it takes to do all this typing.

Opinions appreciated!

It occurs to me that there would be 2 ways to connect the h-stat.

1) In parallal with the t-stat, so that the ac will run until both
standards are met. I'd have to review the thermostat wiring diagram
and how the AC works, or just wait until somene says, to know if this
is an easy thing to do, but it seems like it might be the best.

2) In series so that if either the temp or humidity is low enough the
AC turns off. I think this would be harder to do, and not what people
want anyhow.

If you use method 1, I have the feeling that one stat or the other
will dominate things. Once in a while the other stat will keep the AC
on, but after that it will be the first one to rise, the humidity or
the temperature, that will determine when the AC goes back on again.

Maybe this is usually the temp and that is why most ac run only on
t-stats. ???? I'm just speculating.
