Broan Model QTRE100S Ultra Silent Humidity Sensing Bath Fan. 100 CFM, 1.5 Sones, 4" ducting.
SensaireŽ technology detects rapid increases in moisture levels at the ceiling, where steam and humidity naturally rise. Regular humidistats located on the wall simply detect absolute humidity levels and are prone to false triggers, or not operating when they should.
An automated solution to fight excess humidity and mold.Our humidity sensing fans turn on and off automatically to help prevent cosmetic and structural problems associated with excess moisture.
Hands-free operation.Since you never have to worry about turning the fan on, Broan Ultra SilentT is ideal for problem areas in residential, institutional and light-commercial applications. Our exclusive SensaireŽ technology is a perfect solution for high-traffic bathrooms, or a kid's bathroom.
It turns off automatically, and that saves money.Humidity sensing fans are ideal for anyone who leaves the house before humidity is properly vented. With a fan this quiet, you can't forget to turn it off when the job is done. That saves energy and money.
NOTE: There are 2 different wiring options for this fan - see wiring guide. Use 2-function switch model 68W for option # 2.

. Humidity control automatically turns fan ON when either of these conditions is detected:
- a rapid to moderate increase of humidity
- humidity above factory set-point
. Two wire manual operation for odor control - Turns fan ON when power line through wall switch is cycled ON, OFF and back ON
. Remains ON for 20 minutes after humidity has stabilized and is below factory set-point or after manually initiated through power line cycling
. Saves energy because unit runs only for the time required. A unit controlled with a wall timer may keep fan ON longer than required or turn it OFF before room is sufficiently ventilated
