Yes, you set it for the approximate area and then you can also additionally adjust it be be closer to the current values so it will be a little off once each year unless you adjust it near the solstice dates so it can guess closer. It not like it has GPS or anything like you could do with a full house automation system. I have mine on the entry lights which is an LED lit chandelier over the pond so it only need to be approximate. I changed the lights and switch 4 years ago and all have ran without any problems. It will do both single pole (like I have it) and 3 way. The cover acts just like a normal switch for manual on a off. The timer events are simply triggers and are not altered by the manual state like some timers. If you want to shut them off early you can and they will still go on next sunset. I have mine go off around midnight since I have a street light nearby and a motion triggered spot light covering the access to the front entry area if anyone (or creatures) approaches. That's a lot more effective even if it is only to chase off a thirsty raccoon. I do have to remember to turn it off on Halloween though. Read Less

Answer: 
Kind of. You can select from South, Central, or North. But if you live far north (e.g. Seattle), it doesn't really track it all that well. If you REALLY want it dawn/dusk, you'll need to override the setting a couple times a year.

Answer: 
The installation instructions show how to connect the wires for various configurations, including a 3-way switch. Not all wires are connected in all configurations.
If you don't have the installation sheet, it is right here as a PDF on this product page of the Home Depot web site. I can't remember exactly where; right edge maybe, or under one of the tabs under the photo.

All of the wires coming off the GE 15312 timer are necessary for the timer to function. Due to differing wiring codes, age of the home, and other uncertain factors such as the electrician who originally wired the home, wiring is unable to be identified strictly by the color of the wires in the wall. Please contact a licensed electrician if you are unable to use the wiring diagram because you cannot identify each wire in the wall. This will ensure a safe and correct installation

I connected the switch's black and blue to the outlets black wire. I connected the switch's white wire to outlet's white. I capped the switch's red wire (unused) and connected the switch's green wire to a screw in back plate of outlet's box. I successfully programmed the switch, but I won't turn lights on, nor can I manually turn lights on from switch. Any solutions would be greatly appreciated. Thanks in advance.

Answer: 
Not sure you can do it. It likes the source black coming in, load black (blue on the switch) to go to the light/load, return from load to white cluster with the switch white and return to the breaker. Your wiring isn't in line with what I understand is the current electrical code. ... so you can't do it without wiring from your breaker to the junction box.

In order for a switch or timer to work there needs to be a line, load and neutral to complete a circuit. The one black wire you have connected to the timer is powering the timer. There needs to be another black wire in the box to turn the lights off and on with a switch or a timer. did the original switch turn the lights on and off before you opened the box?.

Answer: 
The previous switch was wired as a "switch leg", meaning the black of the romex is likely a constant hot from the fixture to the switch, and the white feeds from the switch back to the fixture. The neutral joins the fixture directly and never travels down to the switch. A recent code change now prohibits this type of wiring (most likely because of all the new electronic devices which require a neutral). Read More
The previous switch was wired as a "switch leg", meaning the black of the romex is likely a constant hot from the fixture to the switch, and the white feeds from the switch back to the fixture. The neutral joins the fixture directly and never travels down to the switch. A recent code change now prohibits this type of wiring (most likely because of all the new electronic devices which require a neutral). However, as long as the ground has good continuity back to the panel, it will work to use the ground as the neutral. (This is a violation and a big no-no for anything which uses much current, but for something as minimal as an electronic timer, it's fine.) Connect both the green and white of the timer to the ground. Connect the black of the timer to the black coming down from the light. Connect the blue output of the timer to the white feeding back to the light. And of course cap off the red. Read Less

Hi Tomster2000,
Thank you for your question.
Unfortunately this timer cannot be wired in a switch location with only 2 wires. This timer requires your switch location to have access to all 4 wires necessary for a lighting circuit. Your wiring should have a Line (hot), load, ground and neutral wires. A standard toggle switch will have only a Line and Load wire on it (typically it will also have a ground wire, but not in all instances.) Depending on the age of the house and who originally wired this switch, neutral return wires may not have been routed through this location. Typically the neutral wires are a bundle of white wires in the back of the box not connected to anything else. Without all 4 of the wires described above, it would be necessary to purchase a timer that does not require the use of a neutral wire (white wire on the timer.) this will allow you to install a timer in a switch location with only 2 wires.” Read Less

I just experienced this same exact problem after a very short power outage (about 2 minutes). Clock stays on and it shows the unit is "On" but none of the buttons work and it will not turn the lights off. I can't even reset it. I'm going to kill the power to it via the breaker box and hope that resets it.

Rated 3.9 out of 5 by 152 reviewers.
Rated 5.0 out of 5.0 by very nice product I purchased this G.E. timer switch to control 2 dual-brite lanterns at front entry because their photoelectric sensors had failed. I switched their little control switches to constant and now they are controlled by this timer.It's easy to install and It works great and also with the led bulbs I now use. Has been in for 3 months now. You program it to your time zone. I saw other makes on line that cost twice as much and thought that was too much for what I wanted. Then I saw this timer with good reviews and tried it. Glad I did. June 1, 2016
Rated 5.0 out of 5.0 by Nice easy to intall and setup timer Had a previous timer in the garage for outside llights. This one is easier to install, setup and use. Love the bigger numbers in the display and that it is backlit! So far so good. September 7, 2016
Rated 5.0 out of 5.0 by Very SMART purchase!!! I purchased 3 of these. Two of them I use to power on and off my external wall outlets for holiday lighting. The third is used for my front porch lighting. During the holidays I will set the external outlet timers to turn on at dusk and shut off at midnight. During this same time, I set my front porch light timer to turn on at midnight and shut off at dawn. There are a number of ways to program these to fit your needs. Instructions are very easy to read and follow. I am a DIYer and electrical is not my strong suit. If I figured it out, anyone can. You simply can't beat the price when compared to similar timer switches. January 5, 2016
Rated 5.0 out of 5.0 by Set it and forget it! Unbelievable price. For seventeen bucks, I cannot believe this thing! I almost managed to install it myself, except that one blue wire threw me. I pretty much Googled the answer but decided to hire a pro just in case. So the installation cost me $98. Oh, well, peace of mind. STILL, it beats replacing the light fixtures, programming some automation system, etc. ANYWAY, this little gadget knows exactly when the sun rises and sets based on your latitude... okay, it knows *approximately* when the sun rises and sets, but then it lets you fine tune that so with a little Google help you can make it accurate to the minute. Then as the year goes on, it adjusts the sunrise/sunset accordingly so you get perfect dusk-to-dawn functionality. Has built-in backup battery and knows when DST changes. You can even tell it if your area doesn't do DST. (Oh, as for the latitude, no it does not have GPS. You can select a zone within the U.S., including Alaska and Hawaii). So you do have to program it once on these annoyingly tiny keys (but they *have* to be tiny to fit in there), so I had a magnifier and flashlight to get that done; but then it's set forever, nothing to fiddle with, EVER, which is exactly what I was hoping for. Now, if you want to knock yourself out, it will take up to 7 programs, each with its own settings for various days of the week and when to turn on and off. So e.g., it could go dusk to dawn on MWF but on TTh it can turn on at fixed times of 8p and off at 11p. That would consume only 2 of the 7 programs, can't imagine how you would run out of options! THEN, you can press "Random," and it will vary the program by up to plus/minus 30 minutes every time it shuts on or off. All I wanted was dusk-to-dawn, and my fixtures cannot be fitted with a photocell (too small, ceiling mounted by front door), and all other options were much more expensive and involved programming (and maintaining the programming) that I did not want to do. So I am loving this thing. Seventeen bucks! Wow. August 28, 2016
Rated 5.0 out of 5.0 by Timer Review Easy to install and so far very reliable. A little involved to program, but once it was done, haven't had to touch it again. August 29, 2016
Rated 5.0 out of 5.0 by Efficient and automated make life simple Simple instructions, easy installation for a moderately skilled person. Simple to setup and features allow for multiple settings. Would recommend to anyone who doesn't want to think about turning lights on and off again. August 9, 2016
Rated 5.0 out of 5.0 by Great automatic timer for outside or inside lighting Other than the body of the switch being large and a little difficult to push into my three unit switch box because of the extra wiring in it, installation was pretty straight forward. The package comes with everything you will need to install the switch. This is the second one I have installed and if you follow the instructions, which can be a little confusing if your a real novice, they work perfectly. I like the idea that you have many different choices in the setup, like random times on/off, Dawn/Dusk and it changes with Daylight Savings. January 5, 2016
Rated 5.0 out of 5.0 by Great product Works like a charm. Love that it automatically adjust for the change in sunset. August 16, 2016
