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.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Terry Farrell</FONT></DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; = BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: = black"><B>From:</B> <A title=davidskolnik@optonline.net href="mailto:davidskolnik@optonline.net">David Skolnik</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A = title=pianotech@ptg.org href="mailto:pianotech@ptg.org">Pianotech</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Thursday, July 14, 2005 = 4:38 AM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> Re: room climate = control</DIV> <DIV><BR></DIV>Jurgen -<BR><BR>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?<BR><BR>David = Skolnik <BR><BR><BR><BR>At 03:01 PM 7/13/2005 -0700, you wrote:<BR><BR> <BLOCKQUOTE class=cite cite="" type="cite">I have a client with = a 7' Kawai grand in a basement studio.  The Relative Humidity  is = always on the high side (60%).  I urged him to monitor the humidity with = an electronic hygrometer and to get a dehumidifier.<BR><BR>He did this, = however the controller on the dehumidifier in very inaccurate.  With = the controller set at 40%, it cut out when the humidity is still above 60%.  The manufacturer told him they are all not precise.  = He has searched for higher end units, but even the manufacturers of these = do not guarantee the precision of their controllers.<BR><BR>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.<BR><BR>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?<BR><BR>Any thoughts, = and especially experiences, welcome.<BR><BR>Jurgen Goering<BR><A = href="http://www.pianofortesupply.com">www.pianofortesupply.com</A> </BLOCKQUOTE></BLOCKQUOTE></BODY></HTML>
