"With a DC system the hygrometer controlled dehumidifier..." Hygrometer is an instrument one can use to measure relative humidity in air. Humidistat is an electronic device that senses RH and can regulate a dehumidifier and/or humidifier. Terry Farrell ----- Original Message ----- As Steinway generally puts is, controlling the whole room is best but not always feasible and when that is the case a DC system is the way to go. If I understand you correctly, you have measured the humidity and have not noticed any lows dipping into the forties during the active season there. If that is the case, a DC dehumidifier only system with under/back covers would prove adequate for the summer performance season. The low winter temperature if kept steady will probably keep a steady humidity profile for the pianos. With a DC system the hygrometer controlled dehumidifier bars will shut off when they are not needed and you don't have to worry about baking the piano. I doubt a full system with humidifier would be properly maintained if the camp is shut down for the winter. You mention they are in a room kept to 50 degrees. I don't know how cold that area gets but it is possible that humidity levels are acceptably high-enough during the winter. Of-course putting a hygrometer in the room that tracks high and low extremes would reveal any problems. Since it is a presumably small room it may be possible to plumb in a low maintenance humidifier if that is needed for the winter.
