aprilaire analog humidstat 4655 by Alfred R. Lang (Caledonia MI US)

I am very pleased with my analog humidstat, it is so easy to adjust now. before we had to down the stairs to our lower level to adjust the humidstat. we did not do that often enough because of our age and health. now we can adjust the humidy percentage so easily. wish we knew about this humidstat a number of years ago.

humidistat replacement by Doug ( )

I bought this to replace an older one that had not been working. This was about 200 to 300 percent cheaper than if I had gone through the plumber. Although I am not the handiest guy in the world, it only took me about l5 minutes to install.

Works much better than the digital, automatic humidistat that was installed with the humidifier.
