Thanks! Last time I heard that was when I applied for Social Security a little too soon.

I am moving in to tv in 2 weeks. I am interested in installing the humidity control device. Is there a way to use a portable dehumidifier and let that do its job. Can I get the handimans phone #

If the humidistat is wired to turn on the AC when a relative humidity level is exceeded, that might be of value. However, most are wired to keep the AC from turning on until the preset humidity level is reached regardless of the temperature setting.

As the temperature climbs the relative humidity drops for a given amount of moisture in the air. Thus the amount of actual moisture inside your house can keep climbing as the temperature climbs yet still be under your preset level.

We used the humidistat at our place in S. Florida for the first decade while we were away in the summer, thinking everything was fine -- lower electric bills, things looked ok, no mold etc. But things slowly started deteriorating...

It turns out the temperatures were getting into the high 90's inside the our place and, in spite of what conventional wisdom is about mold etc. not growing under 65% (we had our humidistat set to 55% just to be safe) the fabric on our sofas got patches of yellowed areas; clothes developed spots; cameras and other electronic stuff with plastic areas became sticky and gooey.

With the temperature in the 90's and high moisture content (but under the preset 55%) all sorts of problems slowly developed.

who was the contractor for our HVAC system. Last year, I talked to Sun Kool when the did the semi-annual cleaning/tune-up. They said there had been problems with dehumidistats (or humidistats, I can never keep it straight). You know, the thing that's supposed to be good when you're gone for several months in the summer.

Anyway, they talked me into this new thermostat that included the dehimidistat thing and set it at 60%. When we're gone we set it at 80 degrees. This summer we still have tenants in and out, so next summer will be the test, but didn't notice that it was especially hot when I was there earlier this month and had the temp set at 76 during the day (I've tried, but unless I'm sitting still, can't stand it warmer - of course, being there for short periods I'm almost always still doing some project when I'm not shopping, golfing or at the pool. That may change once we actually live there and spend more time watching TV or whatever.
