I've seen $250 humidity detecting fans (Broan?). I have a timer on my bath
fans, and motion detectors on my hallway lights (installed when my dad was
dying), so I can't believe they can't make a wall switch which detects
humidity. ANyone see one? Couldn't find one with google. Besides the
bathrooms, I'd wonder if I can't have one for the house when I'm away and
don't want to have the heat or cool on just to prevent mildew. I hadn't used
cooling in years and the upstairs duct perspired onto my ceiling.

Googling "wall mount humidistat" will return hits like the following:

Broan DH100W
Honeywell H46C
Honeywell H8908B
Honeywell H600A
Ranco J10-821

There are many humdiity detectors available today. None as a switch,
as they require a good air flow (and a switch won't have any air-flow)
but you can mount them in unobtrusive places (such as near the fan) if
you wanted, and use the wall switch as a master on/off.

Mold in a shower is normal and easily killed by laundry bleach, mild
elsewhere is caused by water, either leaks or condensation in winter.
A humidity fan wont fix what you think it will and will trigger on a
rainy day bringing in more humidity.

I have been using one for 3 months and I like it. I also had trouble finding it.
Think DEW.

Order this one:

http://www.ontimemall.com/nortec-115...midistat..html

It's on sale for $930 but you won't have to spend $250 on a new fan.

Understood. Most of my mold problems are nowhere near the shower.
(Pointing, siding shingles and duct perspiration might be implicated.) When
my mom was alive, we never had mold in the house. After my dad also died, it
blossomed. I stopped using heat and cool because I essentially "borrowed" it
form my godparents upstairs. I had by heat at 57F and cool at 87F and it
almost never turned on. I also kept the rooms locked up because I was rarely
home.

In fact, I have learned over the past six months, when I sudeenly found
myself spending more time working from home, to push the temperature duing
rain so as to trigger more ventillation.

I live where the East and FLushing rivers empty into Long Island sound,
and I am at 45ft elevation on a hill that peaks at 150, but zero elevation is
on the other side of my block, probably swamp landfill. Last year, was
especially humid, our local beaches were closed, dark green from storm drain
overflow.

Do you ever just run your furnace fan for air circulation, without
heating or cooling. ALso, do you do a lot of cooking to raise the
humidity that high?

I bought 2 army surplus one years ago, high quality stuff! I used it to
totally rebuild a donut proofing box because none of the original parts
were available. (the donut proofing box circulates warm humid air
around the raw donuts so they rise without drying out). A fan, a
stainless steel container like in a salad bar with a generic water
heating element installed in it, the humidistat, and a larger container
of water to siphon water in the small "boiler". Sorry I can't recall
where I bought them.

To *measure* humidity, the easiest I've found are the HIH-4000 series
from Honeywell. Vout is very nearly linear against percent relative
humidity (a second-order fit improves it a little at the cost of some
computations). Feed it 5 VDC, read with an ADC, simple.

For a setpoint, though, the GE HS12 or HS15 are cheaper. They must be
driven by AC (no DC bias allowed) and the impedance range is over 4
decades, so it is not just a simple ADC hookup. But just to get a trip
point reading would be fairly straightforward.

Yes I probably bought the same ones years ago. Wrapped in sealed
bags. I just tried using one in my bathroom.
They are not reliable near the extremes. You cannot set it to 80 % hummidity.
The horse hair mechanism is too critical up there. I was able to set it
to about 60%, and one rainy day it just came on. i mounted it uo in the air
box which I had taken out the fan and used an in-line fan for noise control.Its
works OK with the Dew Stop condensation sensor,
but I really need more CFM.
Most mechanical sensors have the wrong connection for fan use.

greg

In my opinion you are all wet, at temperature you have outline Humidistat
would be useless unless you have Dehumidifier run at all times,
and at 57 Deg. F not likely that you will get below 50% rh
so all you doing is wasting your time but lots luck.
