This was used to replace an Aprilaire duct mounted humidistat that was not defective, but would not go above 45% humidity setting. It was a duct mounted unit, and while the humidity in the house was running about 35% in winter, the air, running thru the crawlspace duct, was apparently being cooled enough to raise the relative humidity above 45% by the time it got to the furnace, and so would only turn on the humidifier when the inside humidity was extremely low. This Honeywell unit is capable of a higher setpoint and allows it to operate correctly, to provide humidity to the house at the proper 30-40% range here in Virginia in winter. It was smaller than the Aprilaire unit, so required the old opening to be covered with a new metal plate and the correct opening cut in that new plate. They mention an installation box, but almost impossible to locate one. With proper gasketing, it works okay without, but would have been less work with it. It would be absolutely essential to have that box if you plan to install this in an interior wall and not a duct mount as described here.Read full review

This is referenced as a Thermostat, but it is a Humidistat for controlling a humidifier in order to maintain indoor humidity to keep our nose and mouth from drying out and reduce annoyances like static electricity disacharges. It works great to maintain my home humidity extremely constant at the 50% level even when the outside temperature drops to 5 F and the heating system is doing its job maintaing 70 F inside. Honeywell is a well known and highly respected manufacturer of all types of control devices, and the H8908B1002 certainly lives up to the quality and performance I have come to expect and rely on from Honeywell control products.

Works great, as described, easy to install. It is essentially a two wire on/off switch based on the humidity setting. I use it in Florida for mold prevention in the summer when I am not here.

The humidistat functions although the factory calibration seems to be off. However, the part does provide humidity control in my application so I am satisfied with my purchase. Thanks for the expert packaging for shipment. Very well done. Quick delivery.

Nice appearance, reasonable price. It wasn't clear from the directions that a hole had to be cut when installing on a wall. Otherwise, easy to install.
