Je l'utilise sur un moteur de ventilation a la maison au besoin.

Had one of this exact model in a previous residence and it worked for over 20 years. I have every expectation that this one will continue working for that long and likely both will work until the entire system is replaced for other reasons. This timer is simple to install (about ten minutes of actual install work) and simple to use (just turn the dial). If you need a timer that is really accurate, you may need to look into a digital one, since this relies on a spring and no amount of factory calibration will make it that accurate through its entire range, and make it stay that way for decades. I am using this strictly for DC continuity control.What this does provide is a no-power, no-"smart" switch that works right every time, doesn't need your wifi password, doesn't need a subscription, doesn't lose its marbles if you have a power outage, doesn't send your data and usage habits to an aggregator... on and on.I installed this in a junction box, even though in this application it only provides continuity for 24VDC to control a furnace fan. The spring tension also would tend to twist it out of drywall if it were not adequately secured, so a J-box is a good plan. It may also be required per local code; if you're in doubt, check yours before completing your installation.

منتج ممتاز ، سهل التركيب بحيث ركبته بنفسي دون الحاجة إلى كهربائي.حل لي مشكلة نسيان مروحة تهوية الحمام حيث تطفأ تلقائيًا بعد مرور الوقت المحدد.هناك موديلان ، موديل مع خاصية Hold ، وآخر بدون ، أنا أخذت الذي بدون ، وكان المفروض آخذ الذي مع الخاصية ، والفرق بينهما أن الذي فيه الخاصية يمكنك إطفاء المروحة في أي وقت ، بينما هذا الذي أخذته إذا برمجتها مثلًا على 10 دقائق فإنك لا تستطيع أن تطفئها قبل ذلك ، بل هي تنطفئ تلقائيًا بعد المدة المبرمجة ، نعم تستطيع زيادة المدة ، لكن لا تستطيع إنقاصها ولا إطفاء المروحة أثناء المدة.

Controlo un ventilador y me permite que no se mantenga prendido por tiempo indefinido

I made up a cord and plug and receptical box with timer built in so I can control a charger that I purchased that won't go into float mode. Works great.

Just works as described.

I was looking for a 15 minute mechanical timer switch, and after reading through the reviews, decided to try this one to control my bathroom exhaust fan.The package includes all the parts you need to install the switch, and the timer readout dial plate fits right over the regular switch plate that you already have. The switch fit perfecly into my double-gang switch box, and installation was a breeze. It took less than 5 minutes. The instructions are clear and easy to understand, just two wires to unhook from your old switch, and attach to the new one.As far as construction, it seems well made. I was a little apprehensive after reading some of the other reviews, but I feel that this is constructed about as well as any off-the-shelf electrical parts you will buy anywhere. Fit and finish were fine. As mentioned in several other reviews, the knob does require some force to mount on the shaft, but that's probably a good thing. It shouldn't loosen and come off after extensive use.In operation, it does make some sound (kind of like a wind-up kitchen timer), but isn't too noticeable when the fan is running. When it reaches shut-off, it makes a distinctive click. You can adjust the time, either adding to or subtracting from it, after making the intial setting. You can turn it back to "zero" to shut it off, but I don't know if that would be good for it if done regularly. I set it for 15 minutes, then turned it back to 5 minutes, and it didn't seem to be any problem at all.Overall, I'd recommend this item. It has a one-year warranty, and was made in Tunisia.Update after 9 months of use:Still going strong as ever. I can only guess how much money it has saved me in lost-heat costs from the house when people used to forget to turn off the old, regular switch, and it would run for hours. Set it and forget it.

Timer description matched the product exactly. The instructions list three different models of this timer switch. The difference between models only appears to be how the wires connect. The timer came with two screws to mount to the electric box, and two screws to make the wire connections. It also came with the timer plate and nut to fasten the plate, and the knob. Wire connections were easy, although you have to look closely to see the molded in "line" and "load" markings. Basically its black wire feed to the line connection, then the fan (or other device) to the load connection. Make neutral to neutral (white) and ground to ground (bare copper) connections as typical of any wall switch. And like the description says, "Supplied with a molded white time dial plate designed to fit either toggle or decorator style switch plates ". That means it only comes with the timer plate, but not a switch plate. (the time dial plate is the rectangle with the time marks on it. It fits a standard wall plate with large rectangular opening).It works as it supposed to and seems accurate with its timeing. The knob was quite hard to turn the first time, but after a few days of use it has loosened up in both directions. The clicking noise of the timer can't be heard over the sound of the whole house fan that is directly overhead. With the power off, I noticed the timer is quiet enough to use with bedroom ceiling fans (which I am considering doing).All in all, its appears to be a good buy. Much less expensive than the choices at the home centers, and at 6 hour timing it is just what we needed for our attic fan.Update: The Master Flow whole house attic fan came with a rocker switch with Off, Low, and High positions. When the fan was installed, I put in a two gang electric box (double box) because I knew I wanted to add a timer. But now with this timer installed, the rocker switch Off position was no longer needed, plus finding a cover plate with the decorator opening on one side for the time, and a custom size hole for a rocker switch on the other was impossible. So I tossed the rocker and got a regular 3-way wall switch, and wall plate with the regular toggle switch opening on one side, and the decorator opening on the other. Then I wired the power to the timer, then to the 3-way. So now the timer functions as the on/off switch, and the 3-way toggle is just High and Low. Much better functionality, and nice clean wall switch plate.The whole house fan I have is a 30" belt drive model that is rated at 4 amps, so this switch is more than sufficient.BTW, the timer switch specs/ratings are:Resistive: 20 Amp, 125 VAC, 50/60 Hz10 Amp, 250 VAC, 50/60 Hz10 Amp, 277 VAC, 50/60 HzTungsten: 7 Amp, 125 VACMotor: 1 HP, 120 VAC, 50/60 Hz2 HP, 240 VAC, 50/60 HzOperating Temperature: -40¢ªF to 104¢ªF (-40¢ªC to 40¢ªC)Style: Can be used with decorator and toggletype switch platesDimensions: 2.79" H x 1.6" W x 1.19" D
