Questions & Answers

What does "no neutral wire" mean?

There are far too many answers all over the place here, in my opinion. 1) "Black" isn't something you wire. to this, add "white" In most applications, the white wire serves as a neutral wire; therefore, unlike a standard single pole or three-pole circuit, this does not require neutral. switch in both directions You connect the line (which is usually black and carries the current) to the load (which is also usually black and powers the light fixture). br>2) If you're replacing a three-dimensional object with this, make sure it's a three-dimensional object. If you're using a three-way switch, you should definitely connect the common to it. The neutral wire is NOT the common wire. In a three-wire system, the common wire is HOT. way to set it up br>3) If the switch you're replacing has a ground (usually a bare copper wire or green), you should connect it to this switch.

I couldn't tell you what color it is because I couldn't tell you what color it is. I'm on the lookout for a white switch. ?

Yes, it's white; there's probably an ivory version as well, but the one I ordered and installed was white.

Is this compatible with incandescent lights?

That's correct. It's also effective with LED lights. I've been using it for about 6 months to turn on and off the lights on my porch/garage (LED Bulbs) at dusk and dawn.

Is it possible to use it as a standard on/off switch when necessary?

Yes, there is a switch hidden behind the flip cover. It is possible to turn on or off the light by gently pushing the cover.

YOU WILL NOT USE ANYTHING ELSE AFTER USING AN ASTRONOMIC TIMER
5/5

As a licensed electrician, I've installed this Intermatic, ST01K, Astronomic Digital timer in a variety of settings. They're incredible. It's a great convenience that they turn on and off with the sunrise and sunset times rather than at predetermined times. Unlike traditional light timers, which must be reset on a regular basis or the lights will begin to turn off and on at inconvenient times, this one can be set and forget. It will automatically set the sunrise and sunset times to the current times. This timer can also be used to manually turn lights on and off by pressing the center of the timer cover. This manual on/off feature has no effect on the timer settings that have been programmed. This timer also outperforms photo cell lights in terms of reliability. Photocells are prone to turning on your lights when it is only overcast outside, as well as having issues with the lenses becoming dirty and other annoyances. br>br>This timer can be used as a quick transition or replacement for any standard light switch. It can be used with a single switch or a three-way configuration. The installation instructions are simple and straightforward; the initial setup of the digital timer can be a little confusing, but it isn't that difficult once you have the instructions in hand. br>br>After using a number of them, I'd like to make the following recommendations: First, make sure it's installed in a rainproof receptacle box with a rainproof enclosure/cover if you're going to use it outside. It works well for me even in cold weather, but it won't tolerate being wet. Second, make sure this model number doesn't get mixed up with another Intermatic model with a similar name. This model, designated "ST01K," provides a complete shutoff, similar to a light switch. As a result, it can be used with compact fluorescent lights and other similar light sources, whereas other, often less expensive models simply dim the light until it is no longer visible. That model is not compatible with all light bulbs. This timer uses a battery to keep the clock going. The battery should be checked first if the timer isn't working properly. I've usually been able to get a few years out of the battery before having to replace it. I have, however, installed some in which the included battery was defective right out of the box. From the front of the unit, you can easily replace the battery. To do so, the timer does not need to be removed from its electrical box housing. br>br>Don't be hesitant to use these timers. br>br>I hope this was of assistance,br>DBbr>Leesburg, Florida.

It's simple to put together, but it's a tad tight
5/5

a few suggestions 1) Before doing anything else, insert the battery (there's a video on how to open the battery door at 2) Setup the programming BEFORE mounting this on the wall (it's now powered by the battery). Follow these steps to get from dusk to dawn every day of the week: It doesn't get any easier than this (well, it could, but it doesn't). When performing the initial RESET, make sure to follow the instructions and hold down the ON/OFF button for three seconds after releasing the RESET button. That step is easy to overlook. The most difficult part was getting the unit flush with the wall, as there was no room in the box for it with all the wires and wire nuts. So I cut the wire nuts off the RED and GREEN wires (which weren't needed for single pole installation), clipped the exposed wire ends, and wrapped shrink tubing around the ends to keep the wires from making contact; even with this modification, getting the unit into the box was nearly impossible. I'm not sure how this unit compares to others, but it does have the advantage of not requiring a neutral or ground connection. Even if it had, the additional wire nuts that would have been required would have prevented it from fitting.

If you don't have access to a neutral wire, use this timer
5/5

Because I live in an older house with no neutral wire, my options for timer switches were limited. This Intermatic appeared to be the best option for me. The process of installation was fairly straightforward. It could have been easier to program, but if you follow the instructions, you'll be fine. For me, the astronomical material was a little shaky- The shut-off time was about right, but the automatic turn-on time was a little too early for my liking (it was already dark when it turned on). ) As a result, I ended up writing my own turn-on/off programs. The battery tray is a little strange-looking. I initially thought I'd break it because I couldn't figure out how to open it. I'm hoping the battery will last a long time, so I won't have to fiddle with it too much. Overall, it's a good device, and I'd recommend it to anyone who needs a timer and lives in an older home with no neutral wire.
