I need a plug-in timer that I can turn something ON for 5 minutes every hour. What can you suggest? Henry

1) Set current time:
Press reset button to clear all programs , display should flash 12:00 AM Monday
Press and hold CLOCK button.
Press Hour, minute and day buttons until current hour minute and day display.
Release Clock button.
Next step is to program the timer
Example shows how to turn on at 5PM each day and turn off at 11 PM each day.
2) Programming review: Each program requires ON time to be set, and then OFF time to be set For example you set Program1 ON 5:00PM for ALL days. And then you set Program1 OFF 11PM for ALL days. Minimum on-off set time is 1 minute.
3) Programming steps: Press PROG button until Timer 1 ON appears on display Use Hour button to set 5 PM Use MIN button to set :00 Default selects ALL days (If you want other days, press DAY button until display shows correct block of days) Press PROG button again to save Program1 ON 4) Now for Program1 OFF 5) To set Program1 Off Press PROG button until Timer 1 OFF shows in display. Use Hour button to set 11 PM Use MIN button to set :00 Default selects ALL days (If you want other days, press DAY button until display shows correct block of days) Press PROG button again to save Program1 OFF 6) Program 1ON and Program1 OFF have been set ... so press the CLOCK button to return to current time. If you want to set another program, press PROG button until Timer 2 ON displays 7) After setting programs, press Clock button so current time shows. 8) The manual shows one more thing ... if you program the timer during the hours 5-11pm, and the timer should be ON during those hours, you have to 'tell' the timer to turn ON by pressing the manual override ... after that the timer will operate normally.

Open following link to identify TM311 timer:
http://www.amazon.com/Intermatic-TN311C-Heavy-Grounded-Timer/dp/B00002N5FO

1) First of all, you would need more turquoise 107TN222 ON and red 107TN221 OFF trippers.

2) BUT big problem is that TN311 time dial is divided into half-hour segments, so minimum on-off is probably 1 hour since it takes 2 trippers for on-off cycle, and width of 2 trippers is same width as 1 hour.

3) Open following link for plug-in timers with 15 minute segments shows Woods 49664 & Stanley 31192 & Sylvania SA110
http://waterheatertimer.org/Woods-timers-and-manuals.html#49664

4) Notice the 49664 dial, that each hour is represented by 4 segments. This says timer on-off period is 15 minutes.

To set this timer, you would pull up all segments around the dial, and then push down 1 segment for each hour that you want timer to turn on for 15 minutes.

5) TN311 has 3 prong grounded outlet, Woods 49664 has 2-prong outlet.

6) Stanley 31192 timer and Sylvania SA110 have 3-prong grounded outlets and 15 minute intervals.

7) You cannot accomplish 15 minutes intervals for 12 periods a day with programmable digital timer.
Most digital timers allow 1 minute program times, but are limited to 6 or 7 programs, and not the 12 separate on-off periods needed for your project.

You need to program the timer so it turns on-off at specified times.

But first we need to identify your timer for sure.
Have a look at link below.
http://waterheatertimer.org/Woods-timers-and-manuals.html#59203
If your timer does not show, then add a comment with description of timer.
I have extensive files on timers.

Intermatic DT300, GE 15091, and Woods 59203 are the same timer.

Here are instructions for Woods 59203:
Plug timer in until battery is recharged.
If display will not show, then timer battery needs to be plugged into outlet for 1 hour until internal battery is recharged, or timer is bad, or electric circuit is tripped off, or electric circuit heeds to be tested with circuit analyzer.

Once display shows, then unplug timer for programming.
Set current time:
Press and hold CLOCK button.
Press HOUR and MINUTE to set correct time with am and pm.
Press Day button to set current day.
Release clock button.

Program timer:
Press PROGRAM button until "1 ON" displays. This is program1 ON.
Press MINUTE and HOUR buttons to set ON time for program1
Press DAY button to choose day or group of days for program1 ON

Press PROGRAM button until "1 OFF" displays. This is program1 OFF
Press MINUTE and HOUR buttons to set OFF time for program1
Press DAY button to choose day or group of days for program1 OFF

Press PROGRAM button until "2 ON" displays. This is program2 ON.
Repeat steps above to set ON and OFF time for 5 programs.

When programming is completed, press CLOCK button to exit programming.
Press ON/AUTO/OFF button until Auto displays.

Make sure lamp is turned on.
Make sure bulb is good.

If instructions don't fit your timer, then add a comment with model number or full description and I'll post those instructions.
Also you can take advantage of Fixya phone service where expert speaks with you over the phone for a price.

1) Open link below so we are talking about same type of household system
http://waterheatertimer.org/Water-heater-recirculation-system.html

2) 15 minute interval is misleading.
Pins located on timer dial divide 24-hour day into 15 minute intervals.
You set timer pins and decide which 15 minute intervals you want ON-or-OFF. Do this by moving pins inward or outward with your thumb or ink pen. To check settings, manually rotate timer dial clockwise and listen for pump turning on-off..
Set timer pins for 4 consecutive 15 minute intervals, then timer runs for 1 hour.
After pins are set, then manually rotate dial to set current time.
Dial rotates as time passes, and pins click a lever that turns pump on-off.

3) 5-year Life span. Like all things plumbing, if you have hard water or sand-n-dirt in water lines, then pipes clog. And pumps clog.
Once motor begins to slow down, it overheats and burns out.
Water softener can keep sediment out of lines, but shortens life of water heater.
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html

4) Real question: do you need a circulation pump? Do you need hot water at your faucet? Can you schedule hot water use, or does recirculation pump have to run several hours per day?
Recirculation pumps causes water heater to run more, the pump consumes 25+ watts depending on pump, and water savings claims of 15,000 gallons per year are fabrication.
Realistic water savings is 700-2000 gallons per year, assuming several folks in the home use water sporadically across a full day, and each time water is used people are waiting for hot water. It also assumes that you never want cold water at the tap and that refrigeration ice maker line prefers hot water to cold.

Hi, My Name is Henry. I am one of the technicians here.

It may be that the battery has gone totally flat and needs boosting to start charging or simply that its dead. Another possibility is your ac adaptor charge. You need to check to see that that is working.

If still not working. I suggest you invite a Laptop repair technician.

Please do not forget to rate my solutions to you.

Regards
Henry

You will need a more sophisticated timer than most hardware stores carry. Go to Smarthome.com and click their timers and automation section. There you will find many levels of sophistication in timers. good luck
