IMHO, you are not missing a thing. In fact, I think you are right on. =
That is why I recommended the Sears dehumidifier with electronic =
humidistat. I used one for years and it kept my shop (in muggy Florida) =
within a couple percent of 45% RH. I did set a small fan on top of the =
unit and kept it on low to insure good air circulation.

  I can't give you specific recommendations (research required), but I =
would not be so quick to drop the idea of a room humidifier, especially =
in a basement space.  Most of the time, unless the basement is naturally =
dry, some type of dehumidifying process is necessary, even apart from =
the presence of a piano.  I'm sure there are varying quality units, as =
well as perfectly reliable humidistats that can be optained.  It may =
well be that you would have to rewire a unit to bypass the built-in =
sensor if you want to run it through a better grade humidity-sensing =
switch, but I wonder why you couldn't just use a standard (quality) =
appliance and adjust the setting based on whatever hygrometer is being =
used (also, hopefully of some quality), ignoring the nominal setting on =
the appliance entirely.  Am I missing something?

    He did this, however the controller on the dehumidifier in very =
inaccurate.  With the controller set at 40%, it cut out when the =

precise.  He has searched for higher end units, but even the =
manufacturers of these do not guarantee the precision of their =
controllers.

    I would prefer to control the environment in the studio because it =
"should" be a straight forward thing to do.  I feel a Piano Life Saver =
System will simply always be fighting the higher humidity in the room.

    I have thought of using a Piano Life Saver humidistat to control a =
simple room de-humidifier.  Would this work?  Would he need a relay  =
between the humidistat and the de-humidifier?

    Any thoughts, and especially experiences, welcome.
