http://waterheatertimer.org/Intermatic-st01c.pdf

1) Manual shows troubleshooting steps. Since ST01C is battery operated, it will not work on loads farther than 100 feet away. If a wire is buried underground, this can interfere with operation. Other electrical devices can interfere with operation. Check for interference issues.

2) Try reprogramming timer
To program the ST01C:
http://waterheatertimer.org/ST01C-program.html

3) ST01C has 1 year warranty + troubleshooting steps in manual, implying short life expectancy. Similar EJ500 has troubleshooting + 1 year warranty. Similar Intermatic EI600 battery-powered has troubleshooting + 5 year warranty. Each offers 40 programs per week.

3) Other in-wall programmable timers offer 7 on and 7 off events per week. Clock operates on 120V instead of battery. Ttroubleshooting is: reprogram.

The timer flashes, "no-op". Refuses to turn


no-op means 'no operation.

The manual says last resort to revive non-working timer is RESET timer.
This action will delete current day setting and all programming

Hold down ON/OFF and use paper clip to push in reset button for 2 seconds.
Release reset button but keep holding ON/OFF button down until INIT flashes on screen
Then release ON/OFF button and 12:00 should display.

At this point, timer can be re-programmed.
Simple step by step shows on following link:
http://waterheatertimer.org/ST01C-program.html

If timer will not accept programs, or operate after RESET, then timer has gone bad.
ST01C comes with 1 year limited warranty.
Most in-wall timers have same limited warranty.

Replacing timer:
-Advantage of ST01C is timer does not need Neutral wire to operate, and wiring can be simple.
-If you are using ST01C for 3-way switching, then easiest thing is to replace with same timer.
-If you are using timer as astronomic dawn-dusk, then replacements include EJ500, Utilitec 0192773, Aube T1034, T1070, T1072, T1073.
-If you are using timer for 7-day operations then there are numerous options:

My wall timer controls an outside lamp with an outlet...when I plug in a timer for my outside lights,the switch turns off after blinking a few times....this does not happen when I plug in the out side...


If you have a battery operated timer like Intermatic ST01C, it may not operate another timer.
The ST01C will not operate circuits farther away than 100 feet, or operate when wires are located underground. Sounds peculiar doesn't it.
I assume these parameters are because of how the battery interacts with electronics inside the timer.
On the other hand, maybe your battery is getting weak.

http://waterheatertimer.org/Intermatic-st01c.pdf
The manual shows incandescent, fluorescent, motors and DC loads.
But manual doesn't specifically include or exclude other electronic devices that might put electronic feedback on the line.

I'll run a test on the ST01C next couple days, and post result on this thread.

The wall timer to my outside lights says "noop"


noop means no operation.
This usually shows on older timer.
You posted under Intermatic ST01C.
Other have written to fixya with same symptoms.

CR2 battery might be bad. Replace battery.
Replace battery quickly and current time remains in memory.
Battery out of timer longer than 30 seconds, then current time and day disappear.
Programming remains inside timer forever with or without battery until timer is reset.
Others report they changed battery and timer never came back to life afterward.
http://waterheatertimer.org/ST01C-program.html#battery

Manual troubleshoot section also suggests resetting timer, and then re-programming.
Manual:
http://waterheatertimer.org/Intermatic-st01c.pdf
To reset timer, hold down ON-OFF button and push small round reset button with paper clip.
Push reset for 3 seconds and release.
Keep holding down ON-OFF until INIT shows on display.
Release ON-OFF and wait for display to show.
If display never shows, then battery is dead or timer is bad.
ST01C comes with 1 year limited warranty.

Advantage of Intermatic battery operated timer is simple wiring, plus astronomic function (dawn-dusk).
All in-wall timers have advantages and disadvantages.

In the Intermatic ST01C, what is the function of the red wire in a two-switch set-up, which [after the second switch] goes to the same place as the [timer-switched] blue wire?


ST01C is battery operated timer with red, blue, black & green wire.
Red wire is used when replacing 3-way switch (for ex: light switch at each end of hall)

Red wire is capped off when replacing single-pole switch.

If red and black wires are combined, lights will blink.

If red and blue wires are combined, timer reverses ON-OFF function (just like a 3-way switch reverses).

See wiring diagrams for ST01C

What is Noops meant? Intermatic Inc. ST01C Digital In-Wall Timer


No operation.
Either battery is bad or timer quit working.

ST01C takes CR2 battery, but folks post on fixya that ST01C quit working even with new battery:

Yes i have an intermatic timer for my outside lights mounted on my wall inside. it seemed to have stopped working. nothing is on display and i changed the battery


If you have a battery-operated Intermatic timer, then it is the ST01C or EJ500.
The advantage of the battery is simple wiring when you replace a light switch.

http://waterheatertimer.org/Intermatic-st01c.pdf

http://waterheatertimer.org/Intermatic-ej500c-manual.pdf

Both of these timers have troubleshooting in their manuals.
Both timers come with a 1 year warranty.

I have tested the wiring, operation and programming of the Intermatic timers and many other in-wall timers.
If the display does not light up on ST01C or EJ500, then the battery is the only reason.
If the battery is not working, then the timer is broken.
You might try cleaning the battery terminals and connectors located inside the pull-out tray.

geno_3245_3.jpg

These small electrical devices do not have repair parts.
When the timer goes bad, you buy a replacement timer.


You can buy another Intermatic battery-operated timer and keep the simple wiring:
http://www.aplussupply.com/intermatic/timer.htm

You can also buy Aube T-1034 rechargeable-battery-operated timer.
The T-1034 is strictly sunrise-sunset.
The T-1070 is sunrise-sunset -and/or- multi-day programs

The page below explains the Aube
http://waterheatertimer.org/Aube-timers.html

The links below sell the Aube
http://michaelselectric.com/catalog/index.php?manufacturers_id=60
http://www.amazon.com/Aube-Honeywell-TI070-3W-Switch-Programmable/dp/B001QFZ404

T-1034 and T-1070 wiring is slightly different than Intermatic, and you can add a comment and I will help you with any wiring question.

Suddenly the timer is not turning on the lights. The screen on the timer says "SOU". ????


Here is link to product manual at Intermatic. Manual shows troubleshooting, but doesn't show "SOU"
Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} http://www.intermatic.com/products/timers/consumer%20indoor%20timers/in-wall%20timers/st01c.aspx

ST01C works on a 3-way circuit > If another switch is involved, or if switch or timer are not grounded properly, it might affect timer. Troubleshoot says disconnect red wire from 3-way circuit, and see if problem continues, and then suggests replacing timer.

Manual says if CR2 batteries are weak, then BATT shows on screen. Also says weak batteries will cause circuit not to work.
Check the CR2 batteries: Timer holds programming while you replace batteries and clean terminals.

ST01C programmable timer works on circuits up to 100 feet >> I assume because it's battery operated >> electrical interference affects the circuit because troubleshoot lists 'buried wire' as cause of failure. I guess nearby electrical devices could affect performance of timer.

Timer is rated for 15 amps which means practical maximum of 12 amps >>> so 120 volts x 12 A = 1440 watts max or 14-100 watt bulbs >> if you are running more watts, or running close to maximum, or if timer gets warm during operation, this would shorten lifespan simply by heat affecting the circuit.

Interesting that the EI600, EJ500 & ST01C battery-operated timers each has troubleshoot section in manual >>> implying these timers are problematic. ST01C has limited 1 year warranty. EI600 has limited 5 year warranty.

ST01C has 40 on-off programs per week.

If 7 on-off events per week can do the job, you can switch to the EI500 [click on EI500 to access manual]
http://www.intermatic.com/products/timers/in-wall%20timers/digital%207-day%20time%20switches.aspx
>>> the manual shows no troubleshooting section. The EI500 requires connection to neutral or white wire, since the timer runs on electricity instead of battery

[you can use ground wire instead of neutral]
