SOURCE: I installed the Utilitech self-adjusting timer

Here's a Utilitec page with step by step wiring help:

I've done testing on the Utilitec.
Utilitec timers are made to replace 2-pole switches where one switch (or one timer) controls the lights.

If display shows after wiring timer, then wiring is usually correct
If display does not show, then electricity is OFF
If you are replacing a 3-way switch, the Utilitec is wrong timer
If the wiring is wrong the Utilitec will not function.
If you do not have a neutral wire in the box, the timer will not function

SOURCE: I just bought an older

I think you have the ET70215C SPDT
If this is not your timer, then add a comment.

Manual for ET70215C (same manual is for other models too)

Just as you figured, timer has selectable voltage.
Page 28 shows wiring diagrams and jumper settings:
Timer comes with a jumper, and then you select with voltage by installing jumper

Sample wiring diagram below shows 120Volts:
ET70125 appears to have 8 terminals.
Some models have 5 terminals.
There are many ways to wire this timer. Off hand I can think of 10 different ways.
Add a comment if you need help with a specific project.
In any case, the clock terminals are 1 and 2.
To put voltage to the timer switches in the simplest wiring options, is to put a jumper wire from terminal 2 to 3
If you are using 240-277 voltage with two hot wires, you still need to jumper from clock terminals to switch terminals. For example one jumper wire from terminal 2 to terminal 3 & then second jumper wire from terminal 1 to terminal 6

Wondering how to use a 24 hour compact pin timer to automaticlly turn on my lamps ?? bought 1 yesterday but no clue of how to work it !

Pins are usually up for on and down for off, so put them to on for the times you want the lamps on and vice versa, obviously you can check firstly to be sure which way is on and which way is off.

Can't seem to figure it out. Directions are not specific enough. We set "the time now", but the white/AM, dark/PM is weird. Please help w/ directions. We need the light for chicken house. Light on 5:00 AM...

What kind of Woods timer do you have?

Is the dial turning? The dial is the clock. And the clock needs electricity to work, just like alarm clock. If dial is not turning, the wiring is not right.

Does the manual override turn on the lights? Maybe the slider switch set to OFF? Set slider to "Timer" for timer functions to work.

Wall timer:
If you have 59017 wall timer, it has dark PM white AM. You rotate dial until correct time lines up with little triangle located on right side of center knob.

There are 48 plastic pins on dial ... when pins are moved out, the lights are off. For timer functions, set slide switch to 'Timer'
Correct wiring is needed for timer to work:
Timer black attaches to Hot wire from breaker box
Timer red attaches to wire going to Load (lights)
Timer white must attach to white Neutral (or if your box has no neutral, connect white to bare ground)
Timer green connects to bare ground

If wiring seems right but dial on front of timer is still not rotating, then reverse Timer red and Timer black and see if that sorts out problem.

If this is wrong Woods timer, please re-post question.

The timer remains on all the time. I have to actually go out there and manually turn the timer off. I don't have a manual, so I don't know what the little red plastic flag amd the little black plastic flag...

The BLACK flag is for ON time.The RED flag is for OFF time. Set the Black flag into the rotating timer for the time of day you want the timers to turn ON and the Red flag for the time you want to turn the lights OFF. Once you have the flags in rotate the timer dial by hand and note when the lights go on and off. Adjust the flags as needed. Set the timer for the correct time of day and plug in. Also, you can check the Intermatic web site for additional information.

I have a Taco circulating pump #003-BCY-3 PNP. I don't know how to set the analog timer?

Adjust dial to the correct time. Pivot the white pins out to have the pump work during that time. In other words not just one pin, but all the pins from say 6am to 8am. Was a bit confused the first time I saw this set up as well. Good luck

Wr426 getting really hot, header pipe is bright red.

I would check your coolant first off. Your bike also may be running a little rich (too much fuel) which can cause greater heat. I would try adjusting the little black knob that sticks out of your carburetor, this will adjust your air-fuel mixture. Be careful though, adjusting too much at one time and then riding it hard could damage your bike, i'd adjust it little by little and then ride a bit after each adjustment. See if that helps you work out this problem. good luck

Can't figure out how to set Intermatic timer 111c up to nightlight

Hello. I can help you with this times.

Step one - insert the pins at the times you want the night light to come on and go off. The green pins will turn on the night light and the red pins will turn it off. If you just want one on time and one off time just use one pin of each color.

After you have the pins inserted, set the correct time on the timer and plug it into an outlet that is always on [not one that is controlled by a wall switch].

The override switch will turn the device off if it is on, but just one time. As the next time it turns on it will once again be controlled by the times.

If ou want the night light to come on and off in the evening and again in the morninng, use two green pins and two red pins. Push in a green pin at each time where you want the night light to come on and push in a red pin at each time you want it to go off.

Get back if you need additional clarification.
