SmartExhaust Time Switch - Bathroom Fan Switch - White - 4.5 x 1.75 Inches - Precise Ventilation Control, Delay Function

Very Pleased - owned less than one week: Here in the SE, you can have enough ventilation for a bath or water closet; so the timer is worthwhile to keep it in check when the heat or AC are ON ... to prevent over-ventilating; I like the fan-timer (it stays on for xx minutes after you turn off the light); and I like the yy minutes per hour feature, too, which would be useful in some circumstances to keep a bath or water closet ventilated a bit per-hour; it meets ASHRAE whole-house ventilation requirements and comes with a decal stating as much. I expect this device to be reliable and to save some costs due to leaving a water closet fan on all day (accidentally). Here in the Southeast (Georgia), humidity is the usual battle.

I ordered two of these and I'm glad I did. The installation was fairly simple with the basic wiring knowledge I have. I can now walk away with my bathroom fan still running and know it will turn off in 10 minutes. This will help with motor life, wasted power and also keep the mold and mildew down in our bathroom. The delay time is adjustable and it also features an hourly exhaust feature which will run the fan automatically for the selected minutes every hour. The unit also has a separate power source for a light if you need it. If this switch lasts it's a definite home run.

Works exactly as described, easy to install, easy to set.

Works exactly as advertised. Easily installed -- though it's a bit beefy and installs best in a deeper box. My only complaint is that, although I ordered "white," the switch looks ivory to me. Package says it's white. It's definitely a different color than the white switchplate and other switches installed in the same electrical box.

The internals are breaking and now randomly turn off the fan. Sometimes it goes close to the set ~15 minutes before turning off, sometimes as short as 20 seconds, and anywhere inbetween. The switch has become difficult to operate. It's a good idea, but I don't want to replace it so often for the price. There are cheaper solutions if you have the space in the junction box that can be wired in.

This controller is an excellent option for those who are looking for a unit which is elegantly simple. Controls are set behind the cover plate and the user just has access to a toggle switch. This gives the illusion of a simple on/off control with hidden, intelligent automation happening behind the scenes ensuring adequate ventilation. Great for users that don't like fiddling with fancy gadgets.

Toggle Switch wasn't even assembled, poor engineering.

Easy to install, and easy to set
