Replaced a very old humidistat with this model. Very easy to install and works much better than the old one.

This unit was fairly easy to hookup and came with wall anchors. This was the cheapest place that I could find on the internet that looked have way legit with my credit card information.

from Massachusetts on 2/8/2010Comments about Aprilaire #4655 Humidistat:
Replaced one that was 15 years old that had stopped working though it was receiving power from the 24v transformer. The footprint was slightly different, so I had to get out my metal shears to set it into the return. The old one was mounted flush. I noticed that the ribbon technology in the new product was identical to the old one.

from Ohio on 1/7/2010Comments about Aprilaire #4655 Humidistat:
We purchased this humidistat control to replace an old brown control that was an eyesore. We have an Aprilaire 550 whole house humidifier and this new humidistat was easy to install - in fact it was identical to the original control. Just a quick switch of wires and that was it! We're thrilled with our purchase and know this was an easy update that will help with our homes resale value.

from Mystic, CT on 10/24/2009Comments about Aprilaire #4655 Humidistat:
Product very simple. Works as advertised. I was replacing an older unit that had a larger opening in the duct, so I had to cut a larger piece of sheet metal to cover the larger hole, then made a cutout the correct size.
