Aprilaire 4655 Manual Humidistat With 24V Transformer – Open Box

This is an open-box Aprilaire 4655 manual humidistat, and it's in excellent, like-new condition.

It even comes with the 24V transformer included!

The box might be open or a little beat up, but the unit itself has no signs of wear.

It's the perfect controller for your in-duct whole-home humidifier.

You just dial in the humidity level you want, and it handles the rest.

White color, classic Aprilaire reliability, and it's ready to mount on your return duct.

A great deal on a unit that's practically new without the full retail price tag.
