Florescent bulbs are not discontinued.




Incandescent bulbs are being phased out so you can save electricity to run your great-big 600 watt TV....

Or, in a few years from now, you can support the economy and buy another timer:

Buy new EJ600... same keypad as EJ500, except different wiring since neutral wire required

or

Buy ST01 or Ei600 timer: identical wiring to EJ500, same dawn-dusk or programmable options, higher load rating, works with any voltage, CFL, LED etc, different programming steps, different battery.

Ej500 has 1 year wareanty

ST01 has 1 year warranty

Ei600 has 5 year warranty

My wall installed intermatic timer will not shut offf. Either by the program or the manual switch. Help appreciated


Timer model is not known.
Last ditch troubleshoot for ST01C, EJ500, and Ei600 programmable timers is to change battery and then reset timer.
Battery is inside compartment located below programming buttons.
Make note which way battery/batteries come out for easy replacement.
How to reset these timers: Hold down on-off button. Push reset momentarily. Keep holding down on-off until display shows INIT. Release on-off button and 12:00 is flashing. Reprogram timer.
If functionality is not restored, then timer is bad.
ST01C and EJ500 have 1 year limited warranty.
Heavier duty Ei600 is same as ST01C, but has 5-year limited warranty.

I have a Intermatic Wall Timer Model EJ500 and I only have 3 wires and can I usethe Wood Model #59028 and where can I get one if it works. I had a single pole switch when I installed the Intermatic. The...


Yes you can use 59028 if you have Neutral or bare ground wire.

EJ500 is battery operated.
Woods 59028 uses electricity to power internal electronics. Like plugging in alarm clock so timer mechanism works.
That's why 59028 has white wire and EJ500 does not.

EJ500 can be used for 3-way switching, so it has extra red wire that is capped off in single pole operation. EJ500 blue wire connects to Load (light,fan, motor)

59028 is for single pole only. The red wire connects to Load.

Here's how to wire 59028:
http://waterheatertimer.org/Woods-timers-and-manuals.html#59028
1) Timer-green-wire connects to bare ground wire.
2) Connect 59028 red wire where EJ500 blue wire was connected.
3) Connect 59208 black wire where EJ500 black wire was connected.
4) When electric box does not have white neutral wires, then connect timer-white to bare ground.
5) Turn on electricity, and push door on 59028 timer to activate on-off override. If Load comes on, timer is wired correctly. If Load does not come on, then reverse timer-red and timer-black wires.

You posted under EJ500 Intermatic battery-operated timer.
If you have different timer, add a comment.
I have tested EJ500 timer.

A) If this is new single-pole installation and lights click on-off when timer turned on, then you connected red wire where blue wire should be connected.

Manual says for single pole switch:
Timer-black-wire to Hot; Timer-blue-wire to Load (lights)
Here's how to wire timer correctly:
1) Timer-green-wire connects to bare ground wire.
2) Switch has 2 wires. Take switch wires and connect them to timer-black-wire and timer-blue-wire. Choose either one for now.
3) Put wire nut on red wire.
4) 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-blue and timer-black wires.

B) If you are replacing 3-way switch, view wiring diagrams shown on link below, and then add a comment saying exact color of wires. To wire this timer for 3-way can require additional wire between switches. This is because EJ500 blue wire must always go to Load (light, fan, motor)
http://waterheatertimer.org/ST01C-program.html#EJ500-wire

C) If this is older timer that stopped working, check your bulbs. Then check timer battery. Manual says if timer stops working and bulbs are good, and battery good, then reset timer and reprogram. How to reset timer. Press reset button while holding down Next/ON-OFF button.
EJ500 manual has long list of programming instructions: Add a comment if you forgot parts of programming.

Battery-operated Intermatic timers can develop problems.

1) Battery may need to be replaced.

I answer questions for free.
I specialize in timers.
According to Intermatic, they no longer make the light switch timer.
I cannot find the instruction manual on Intermatic.
http://www.intermatic.com/customer%20service/instruction%20manuals.aspx

From my experience, I suspect that the timer is old and does not function any more.

Intermatic also makes another timer that is simple to operate.
It is called the EJ351 but it has to be wired into the wall.

EJ500 has 1 year warranty. The reset button sits naturally lower than other buttons.

The manual shows troubleshooting.
http://waterheatertimer.org/Intermatic-ej500c-manual.pdf

If timer is blank: display bulb burned out; press next/on/off, other timer or switch has turned off power to EJ500.

Maybe a new timer is needed. ST01C (1 year) & EI600 (5 year warranty) each offer same 40-programs per week.

Timers shown above are battery operated, and cannot operate load farther than 100' from timer.

EI500 & GE 15086 offer 7 programs per week ... 7 on events and 7 off events.
