Review on ENERLITES Countdown Timer Switch For Bathroom Fans And Household Lights, 1-5-10-15-20-30 Min Settings With Manual Override, Always On Blue LED, Neutral Wire Required, UL Listed, HET06A, White, 2 Pack by Bryan Finken

I have long wanted fan timers in our two bathrooms because we tend to forget the fans they run all day long, so i couldn't resist this deal when I saw it. The timers came attractively packaged with their wall plates and fasteners and wire nuts, so it was a simple swap with the existing switches and they work as expected.There are six buttons that correspond to the amount of time to run the fan. Simply push the one you want and walk away knowing that you did your part to clear the air without emptying the house of its heat. The larger button on the bottom will either run the fan for the amount of time last used (for which one of the timer lights will be lit, so you know how long), cancel the fan, or put it into manual override to stay on.Each button has a light on it. The light on the big button goes out whenever the timer is active (fan is on). The lights on the individual buttons light only for the currently selected one and blink shortly before the timer is about to time out, All of the lights go out when the timer is set to run in manual override, which is done by holding the big button in for about three seconds. The LEDs are all tiny, but extremely bright. This shouldn't be an issue but I thought it worth mentioning.When considering this switch, remember that it requires four wires to work. A hot (Black), a neutral (white), a switched output (red), and a ground (green). All four will almost always be present if this is replacing a switch where there is already an existing fan circuit. If you have any question about this then you probably shouldn't be doing electrical work in the first place.
