Hi Jurgen, Put in a full system (H-4 wet humidistat, humidifier with smart heater bar, 2 or 3 dehumidifiers) and make sure you get the "wet" humidistat and use a full undercover and I think you will be pleased with the results. I have a client with a house that is always at least 70% RH, and sometimes 80% RH, and their grand piano finally settled down after a full DC system and lots of tuning. Sincerely, David A.
