At a casual glance, you'd never know that a ventilation fan is at work above your shower. While the Broan 744SFL looks like a recessed light, inside is a humidity sensing switch that triggers a cleverly concealed and quiet 70cfm (cubic feet/minute) ventilation fan. The switch knows when the shower begins by sensing a quick jump in humidity. It also shuts off automatically when the job is done so the fan isn't running all day and wasting energy.

Humidity control automatically turns the fan ON but it can also be activated with two wire manual operation for odor control which turns the fan ON when the wall switch is cycled ON, OFF and back ON. The fan will remain ON for a user-adjustable 5 to 60 minutes after humidity has stabilized and is below set-point or after manually initiated through power line cycling. It will save energy because unit runs only for the time required as opposed to turning it on and forgetting you have done so. A unit controlled with a wall timer may keep the fan ON longer than required or turn it OFF before room is sufficiently ventilated.
