Humidistat for de-humidification bar and piano humidifier
Humidistat for climate control unit. Dial up the amount of humidity you want your piano have and the humidistat toggles on either the De humidification or the humidification 110 outlet. This in turn turns on a heater bar for de humidification (sold separately), or a humidifier unit (sold separately). Can be used for humidification or de-humidification or both depending on your need and situation
Without this Humidistat you can do harm to your piano in the winter. Often people leave their dehumidification rod in their piano turned on all year. In the winter when humidity goes lower than 39% you can do damage to your piano. Water preserves wood. When the dehumidification rod comes on when you really need humidity you can do great harm to your piano. The soundboard can crack, the pin block can become loose. Believe it or not keys can stick in low humidity as well as high. I personally believe you can do more harm to your piano by keeping the humidity too low than too high. The problems that incur because of high humidity are a nuisance. The problems you incur from low humidity can be fatal to your piano. The best scenario is a constant and consistant humidity such as the Dampp Chaser life saver system. However if you can’t afford to have a tech come and install the Dampp chaser system this is a do it your self solution for a fraction of the cost. A humidifier can be purchased at walmart for as little as $30-40.00. With this controller you can set a humidifier next to the piano and plug it into one side of the controller and but the dehumidification rod(s) in the other 110 outlet. This unit is a must for a proper installation.
