- I installed this timer without recording it. It's a basic install. No neutral required. Two black wires come out of the device. I also talk about how to program the timer.
Model # EJ351 Night Sentry Solid State Timer
Thank you... I found this in the house I got and is a nightmare. I will be change it soon. But for now it works.
Definitely change it.
I had a timer just like that. Never worked right. This model timer only works with incandescents, and I wasn't going to be chooching 540 watts of incandescent all night. At that rate, it's half a kilowatt-hour per hour for 12 hours every day, just for light you're never going to see!
The timer actually has some pretty advanced features. It's made by Intermatic, and according to their website it's still made. The website states it can be used with Decora or Standard switch plates.
Apparently, it can handle multiple on/offs throughout the day, up to 48. If you don't program the times, it will remember the on/off for the first day, so if you turn it on at 5PM and off at 5AM, the next day it will do the same just by itself. I always found it rather "hokey" the way it needs to be programmed.
It claims it has a 15 minute memory against power failure and will remember the settings. It also has a "random" function that will turn the lights on and off at _slightly_ different times every day to make it appear not programmed, but I think that's more of a function of it requiring no neutral!
Intermatic sells other timers, ones that have LCD screens so help you "see" the time you're setting for on and off. Those timers either have a Ni-MH battery that eventually will not recharge, and then the whole timer would have to be replaced, or a Lithium battery that will last for several years before junking it. Planned obsolescence.
They also sell motor-driven mechanical timers, but those require a neutral. They are the best type since they can control any type of load, as they are physically flipping a metal switch contact inside. That will work with any type of light, including CFL, LED, plasma, and whatever other "eco-green" lighting technology incompatible with the rest of the world will be. It can even turn a motor on or off whenever.
But the problem with a timer for lighting is the time for it to go on and off really needs to change every week! The days keep getting longer and shorter, so the wisest move is to use a photocell. When it gets dark it turns on, when it gets light, it shuts off. Fully automatic.
When replacing one of these with a normal switch how do it do it being it’s no white negative
Should just be the two wires on the switch.
@@xjoe81x 3 way switch thanks I figured it out tho
Okay.
