Comments about Aprilaire Aprilaire #4655 Humidistat:
Had to resize hole on return air duct to replace old unit. Due to location this was a little tricky, but that would be a problem created by the original installer. However, some sort of adapter plate would be a handy accessory.

Comments about Aprilaire 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.

Comments about Aprilaire 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.

Comments about Aprilaire 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.

Comments about Aprilaire Aprilaire #4655 Humidistat:
The unit works just fine, but I had to improvise because the new unit did not fit over the "cut out" in the plenum in exactly the same fashion as the old one. I was able to use part of the old unit's "plate" to install. Don't know why they change sizes on these things.

replacement for humistadt from #560. It needed to have a different size duct opening that I had to cut with a dremel.The dremel made it much easier. Works perfect.

Comments about Aprilaire Aprilaire #4655 Humidistat:
This new control does not fit the old model cut-out , frame, flange and box originally installed with 550, luckily, the gut of control is still the same, so I had to take them apart and use only gut part in the new control and use the box and frame of old one.

Comments about Aprilaire Aprilaire #4655 Humidistat:
Replaced old nonfunctional Aprilaire 440 humidistat. The 4655 didn't fit up to the 440 opening and mounting hole. Had to make an adaptor plate with smaller cutout and hole pattern. Looks like a professional job. The new humidistat looks nice.

Comments about Aprilaire Aprilaire #4655 Humidistat:
I had an old humidity controller and was afraid the new one would work without cutting a new hole. The new controller fit inside the old holder just great. I am glad they used a standard part inside a new holder.

The humidistat is easy to use and is more attractive than the older model. It looks fine in my dining room. The installation instructions did not include wiring instructions ie which screw was for which wire. Fortunately I copied the connections from the old humidistat and they worked.

I was surprised that I was able to find a humisistat that would go with my new thermostat I had just purshased. My old ones were brown. The white ones look much better with my decor and work great.
