May I respectfully point out that the Damppchaser is *not* fighting itself. The wooden parts of a piano take a finite amount of time to begin to react to the changes induced to the humidity control system. You might liken this to the idea of *thermal* drag...i.e. Stone houses are comfortable year round because of the great mass of material. By the time the dc changes from one mode to the other the wood has not begun to *catch* up to the change. I have seen representations from others from time to time about *changes* induced into tuning by humidity control systems switching. I would love to see *hard* data. In my own very sever climate humidity control of a home is near impossible. Those clients who have pianos controlled save thousands of dollars in tuning fees over the years, not to mention lack of cracking soundboards.
