To those who have participated in this thread:

If my language in my initial post sounded strong, you may attribute that to 
my horror at the many times I have found such equipment 
mis-installed.  Installation of this stuff is relatively simple and yet, if 
not done correctly, can cause some of the most profound damage to pianos as 
we have seen.

About 1 1/2 years ago I logged a post about a particularly disturbing abuse 
of a Yamaha grand where the plugs for the humidity and de-humidity devices 
were reversed on the control.  The piano exhibited visible, extreme, and 
irreparable effects from this malpractice.  I tossed out my keyed-plugs 
idea then.

Dear list,

We are aware that there are a number of people (piano technicians, movers 
and piano owners) who may not read the words on the Humidistat and plug the 
wrong component into the wrong Humidistat outlet. We view the solution as a 
2-stage process. The first stage is in process, and as suggested, is 
color-coordinating the plugs and Humidistat outlets. This should be 
implemented within the year.

The second stage involves a re-design of the Humidistat case, which will 
make it physically impossible to plug the wrong component into the wrong 
outlet. The timing of this stage rests upon other changes to the Humidistat 
that are currently under consideration.We appreciate your concerns, and 
your suggestions. We will keep you posted regarding this issue.

My original post is here:

So I am wondering if this reply was really implemented to any degree or if 
it was just lip service.

To Jerry G:  You have inferred that I was suggesting that you would 
compromise your integrity.  My apologies, for that is not what I intended 
to convey with my post, and further clarification is called for.

My point arises out of a hypothetical situation:
Let's say there was a study done, and the results indicated something 
contrary to the purported benefits used to pitch this stuff.  Would it then 
be incumbent upon me to contact my customers for whom I have installed 
these systems and tell them about the study?  It could be quite a dilemma.

I know you and consider you to be one of the most ethical people in this 
business.   I, in fact, share your philosophy of keeping the customer's 
interests at the forefront of my decision-making and that is the reason why 
I am interested in a study.  Since there seems to be no official study, it 
is questionable to me whether or not I can absolutely guarantee them that 
this equipment will do what the brochures say it will.  I also ask myself, 
"Is this really a necessary thing the customer should really pay for or 
will it be innocuous or have a marginal effect at best?"

Terry asked who would be willing to fund the study.  Well, how about our 
venerable organization, The Piano Technicians' Guild?  I think it would be 
useful to have a study on record and I would assume the PTG is impartial 
and unconcerned about losing ad revenue from DC upon 
publishing  less-than-flattering  results, should they arise.

Most likely I'm alone in my thinking and nobody cares whether there is a 
study or not.

I would be willing to participate in data collection with you 
Jerry.  Although I sound pretty biased against this hardware,  I can be at 
once skeptical and at the same time open-minded.  In my opinion, any study 
should involve at least one pair of pianos - one for the hardware and an 
"untreated" piano as a control.  The pianos should also be left untouched, 
so as to avoid any data contamination through tampering.  Unfortunately, I 
don't know of anywhere where this condition exists, except maybe for a 
store with a storage facility, which might involve rental and storage fees.

Gotta keep it interesting

Matt
