P22-T

[Farrell]

Perhaps try placing a good hygrometer (with max and min memory) inside the piano for monitoring RH, and two old fashioned 120V clocks with hands - one plugged into the humidifier and the other plugged into the dehumidifier. Ideally, the owner would monitor these instruments daily and record the data. That would at least give you some info on if and how the DC is operating - it will show you how much RH has changed and how long each part of the DC system has been in operation.
