This system is so advanced it automatically lowers and raises the humidity set point as the outdoor air temperature changes.

Had some trouble installing this humidistat at first. Talked to a very knowledgable, very patient (60 min on phone) tech named Jay. He walked me through the whole process and more. Seems that the #56 unit has been replaced by the #60. More features, more wiring. Job done, new unit installed working fine. Thanks Jay.

This week I finally found time to upgrade the original Aprilaire humidifier controlller to the digital Model 58 controller. Installation was easy, but does require the proper tools. Being able to read wiring schematics is also helpful.
