DC unit abuse

[Cy Shuster]

David,

Here's one statement from DC on their website about the requirement for a 
humidistat:

You may need to login to the Piano Tech "only" area to view it.

What wattage was the heater bar?

I still chase down rumors about the system cooking a piano when the water 
ran out.  In West Virginia, I pulled a lot of old silver 25W bars out of 
pianos.  No humidistat, and most weren't plugged in, either.  We need to 
spread the knowledge about the Smart Heater Bar and the undercover. 
(Actually, the undercover isn't mentioned on their website yet...)
