I would like to clarify how a ventilating dehumidifier such as the Aprilaire 1700 works (probably similar questions, answers for Thermastor too). I understand the 1700 to be cheaper to buy and less efficient to run, than the Thermastor -- that's an OK tradeoff in some situations. I also understand the 1700 has a somewhat better control system.
Is the 1700 designed to ventilate whenever the AC runs? The furnace? My thought here is that it might over-ventilate in the peak summer conditions if something does not reduce the intake of outside air. Or are the Aprilaire designers way ahead of me?
With recent weather not calling for cooling in humid S.Texas, I am just possibly selling myself on adding such a device. It's a whole set of reasons, not least of which is ventilating with that fresh air intake. Although I own a Santa Fe Rx stand-alone, I am just about enthusiastic enough to have a "do again" type of purchase.
Thanks very much -- Pstu
