Swylite LST100 timer has 4 wires. Red, Blue, Black, White
Timer has more wires than wall switch because timer has electric clock inside. And with + series Swylite timer, it also has led bulb that needs power.

Timer can replace ordinary on-off switch
-On-off switch has 2 screws, so 2 wires (plus ground wire) connect to on-off switch
-Three of the four timer wires are used when replacing on-off switch
-Red wire is not used, it is capped off

Timer can replace 3-way switch
-Three way switch has 3 screws, so 3 wires (plus ground wire) connect to 3-way switch
-One of the screws on 3-way switch is colored dark (it is crucial to identify the wire that comes off dark screw so timer can be wired correctly)

Lets replace on-off switch see diagram
Timer black goes to Hot wire
Timer blue goes to Load (light, fan, motor)
Timer white goes to Neutral
Timer red is capped off.

How to check which wire is Hot, Neutral and Load
Switch you are replacing has 2 wires > one is Hot, the other goes to Load
Remove these two wires. Separate wires so you can test. Turn on power. Tape tester leads to wood sticks so hands are away from power. Test each wire to bare copper wire.
When tester lights up >> that is Hot wire >> please connect this wire to Timer black wire
The other wire goes to Load >> please connect this wire to Timer blue wire.
Now test for Neutral. Test Hot wire to other wires inside box. Neutral should be white. When tester lights up, that is Neutral. Please connect Timer white wire to neutral. IF YOU DO NOT have a neutral, you can connect Timer white to bare ground wire until you have time to drop a Neutral into the box.

Replace a 3-way switch see diagram
Three-way switch has 3 wires.
Identify which wire connects to Dark screw on switch >> and then please connect this wire to Timer Black wire.
Timer white wire connects to Neutral
Timer blue and red wires connect to other two wires that came off switch ... they connect to either one.

SOURCE: I bought a Utilitech 7 day digital in wall timer,

HI .. if the switch has only a black and white wire attached, and there are no other wires in the wall box, then you cannot use this timer switch. You need to return it and get a timer that does not use a neutral connection. The wires you have are a switch leg from the light and there is a white wire but it is not a neutral.
If there are other wires in that wall box , tell me and we can chat more about how to remedy this .

Please Vote !!

SOURCE: My GE 7-Day Digital Timer model 15086 flashes on

A comment to samsocal's explanation:

Samsocal's explanation fixed my problem, which was the whole flashing light thing. I started with a light switch that had one black wire in and one out, and a whole mess of white wires connected together in the box that didn't connect to the switch.

In terms that would probably make an electrician pull his hair out, think of the black and red lines forming part of a loop that includes your fixture. Think of the black line as entering it, and the red line as exiting the timer. The red line of the timer goes on to connect to the black line of your fixture.

So:
black power wire -> black timer wire -> into the timer
out of the timer -> red timer wire -> black _FIXTURE_ wire

The white line of your power cord splits into two separate paths. One connects to the white wire of the timer. The second goes off to the white line of your light.

So:
|--> white timer wire
white power wire --|
|--> white FIXTURE wire

<<!!>> If any of your black, white and red wires are connected directly to each other, you've done something wrong. <<!!>>

At its simplest, the FIXTURE loop looks like this:
Fuse box -> black power wire -> (wire nut 1) -> black timer wire -> timer -> red timer wire -> (wire nut 2) -> black FIXTURE wire -> fixture -> white fixture wire -> (wire nut 3)^1 -> white power wire -> fuse box
Your fixture is the box on the wiring diagram that says "Lights/Fans/etc.".

^1 The white timer wire is not a part of the FIXTURE loop. It ties in at wire nut 3 and allows the timer to get power.^2

^2 This doesn't necessarily help you wire things up, but for completeness, technically your timer is in its own loop. It runs:
Fuse box -> black power wire -> (wire nut 1) -> black timer wire -> timer -> white timer wire -> (wire nut 3) -> white power wire -> fuse box.

<<!!>> Although I offer ** NO OPINION ON THE SAFETY ** of what I did, I do not have a ground as my house is too old so I did not connect it to anything, and the timer works just fine. (I cut the ground wire cleanly, stuck a wire nut on the end and then used electrical tape to make sure that it wouldn't come off). <<!!>>

Timer is not identified.
If digital timer does not function as before, try resetting timer and then re-program.
If timer has battery, then change battery and reset timer.
If reset does not restore functionality, then timer has gone bad. Most in-wall timers have 1 year limited warranty.

Below are common 7-day timers, but there are many different brands:

You posted under Woods 7-day timer: except Woods timer does not astronomic dawn dusk function. Woods 7-day is same as Tork 7-day and GE 7-day, and they do not have astronomic function.
http://waterheatertimer.org/pdf/Woods-59018-59028.pdf
http://waterheatertimer.org/Woods-timers-and-manuals.html#59028
Reset button is small round button.
Push in reset with toothpick or paper clip.
Then reprogram timer.

If you have Intermatic ST01C or EJ500 battery operated timer: Replace battery, then to reset timer: push-and-hold ON_OFF button, and then push reset button. Keep holding on-off button until display changes. Release on-off button and display will flash 12:00. Then reprogram timer.
http://waterheatertimer.org/Intermatic-timers-and-manuals.html

If you have Utilitec astronomic timer, then press reset button and reprogram:

I am an electrician and my client wants me to reprogram the digital timer (Intermatic) I don't know the model # but it looks like the one on the previous page. Probably the most popular digital wall timer...


Below are links to digital timers to help identify your timer.
Manuals for each timer appear on page.
Programming takes patience, which might be why your customer wants you to do it.
And these 1-year warranty timers go bad, and then timer will not reprogram, which may be another reason why customer wants you to do it.
Intermatic EJ500 and ST01C are battery operated, and will not program if battery is low.
Aube has rechargeable battery that is not replaceable, and this timer will not program if battery is bad.
Other timers shown below have clocks that operate on 120V circuit and require white neutral before display lights up.

Generally each programming is same: You set current time. Some timers you set daylight savings time. Some timers are 7-day, and some offer dusk-to-dawn. For 7-day, you set event1 ON and then event1 OFF for up to 7 programs. You choose the days for each event to operate. Before programming, make a schedule so there are no overlaps or conflicts in programming.
With Intermatic EJ500 and ST01C, event1 is the ON event and event2 is the OFF event, up to 40 events.

Add a comment if you hit trouble spot when programming.
Also fixya offers live phone support for a price.

Programming remains in memory forever, so you may only have to re-enter current time.

I have a utilitech 7 day in wall digital timer and would like to install it but have no clue how to. can you get me started


You want to install Utilitec in-wall 7-day timer that has 4 wires: red, white, black and green.

You are replacing a single pole switch that controls a light or several lights.
There is not a second switch that controls same lights.

The switch has 3 wires.
Generally there are two insulated wires and a bare ground wire.
Add a comment any time.

Here's what to do:
I have tested these timers for wiring and programming.
Get started and instructions will make sense as you go.
Turn off circuit beaker to switch.
Remove old switch.

1) Timer-green-wire connects to bare ground wire using one of the yellow wire nuts included with timer. Put two wires together so they are even at ends. Put wire nut over wire ends. Rotate wire nut clockwise between fingers until very tight.

2) Switch has 2 insulated wires. Take switch wires and connect them to timer-black-wire and timer-red-wire using two more yellow wire nuts. Choose either one for now. You may have to reverse these two wires in a minute.

3) In back of electric box are white wires twisted together and covered with wire nut. Remove the wire nut, but do not untwist the white wires. Connect timer-white to these wires. Then put original wire nut back over white wires.

4) If electric box does not have white wires described in step 3, then connect timer-white to bare ground, along with timer-green wire.

5) Turn on electricity, and push ON-OFF button. If lights come on, timer is wired correctly. If lights do not come on, then reverse timer-red and timer-black wires from step 2.

Does not turn on exhaust fan motor in bathroom. Display functions work. Could it be the battery or the unit?


The problem can be either battery or timer.
Several people wrote fixya over past months saying that ST01C failed completely after installing new CR2 battery.
http://waterheatertimer.org/ST01C-program.html#battery

Battery operated timer, then weak battery can cause timer to malfunction.
ST01C troubleshoot says BATT advisory does not always display.
ST01C has 1 year warranty.

Advantage of battery-operated timer is simple wiring when box does not have neutral or ground wire.
Battery-operated Intermatic EI600 has 5 year warranty
