TOPGREENER Circulator Switch, Hourly Fresh Air Timer for Ceiling and Wall Ventilation Fan and Bathroom Fan, Countdown Time Delay, LED Indicator, 120VAC, 1/4HP Motor, 3A Max Fan Load, TDTS5-W, White

It has a hour and minute timer. Easy to install. Works great. Just as good as the expensive air circulator controls. I use these often for bath fan installs that meet ashrae specs for state weatherization work.

These are great! Easy to instal. Easy to set........great product!

I bought the 4-pk since we have 4 bathroom fans in our new-to-us home. Our neutral wires (required for installation) were shoved all the way in the back of our light switch boxes, so we didn't think we had them at first. Once we found them and pulled them forward, installation was easy. I will say that in one location we had 4 toggle switches on the same wall plate. Once we replaced the old fan toggle switch for this "rectangular" style (and moved it to the end to fit the new cover plate which I also ordered off Amazon--one with 3 toggle switch openings plus 1 rectangular opening), getting all the wires shoved back in the box was a challenge. This product does take up more room.

Easy to install.

Easy to install and easy to use. Much better than the old turn type, simple button on with led light.

Not the first version of this timer to hit the market place, but a very good value nonetheless. This 2-pack is a nice deal. I frequently install these in pairs so I like this deal. A few notes: 1. mine came with additional slide-on face plates: light almond and black (even though not mentioned in the description). 2. The default setting is a single flash for the button selected and then there is no visual indicator after that. If you press and hold the 1 and 5 for 3 seconds, it will keep the selected button lit. My experience with this type of timer is that if the power goes out, it will revert back to the single flash mode. Since most people prefer the constant-lit mode, it seems that should be the default. 3. This timer does seem to operate just fine in parallel with another timer controlling the same fan. Just be sure that your two timers are on the same circuit, so you don’t accidentally send 220v to your fan (done by being on two separate phases from the service panel).

Nice switch. I buy these often when installing Ashrae 62.2 bathroom exhaust fans.Great quality comes with wire nuts and good instructions.

I installed it by myself, it took me 20 minutes to finish everything.The only thing I can't figure out that where can I purchase I cover to make it look like a regular switch?

easy to install. however I did need to use a little extra piece of wire cooper for the ground connection (I was not expecting that). The back of the timer is big so, it requires a little extra effort pushing and organizing wires inside the wall but it was expected base on other reviews. I do recommend this timer. the 2 hour or 4 hour option may sound excessive for some people but in my case my bathroom does not have windows and it has a little problem with moist and humidity so the 2hr-4hr are perfect for my bathroom.update review 05/12/2020It has been 15 month since I bought the timers. Everything perfect.

Works very well and saves electricity. I have it working on my electric towel dryer in my bathrooms for several months now. I used to switch on the towel dryer and forget to switch it off costing me fair chunk in power bills. Not anymore, I switch it on the 1 hour setting and use a warm towel every time I shower and there is enough time/heat to drive some moisture out after use and the towel nice and dry for next use n a few hours. Having multiple settings is very handy to use it to stay on exactly as you need it to be. Great product, excellent quality.

These are my 2nd batch of these timers. First batch almost 2 years old, and still working great.As timers have a much larger “body” than a regular switch, so you have to make sure the electrical back box is large enough to accommodate the new timer…

Love them. Easy to install. The range of timer is good for a bathroom with a shower, although 4H is a bit of an overkill.The only complaint is that the indicator lights don't change when the time counts down. If you set an one hour timer, the indicator stays at 1H.

Good product but it’s bulky little bit hard to install in the box
