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.

I recently replaced my Intermatic EJ500 with a new unit, I noticed it works perfectly fine for one day then the batteries that control the timer drain completely the following day, what could it be?


Line voltage usually controls the timer functions when properly wired until a power outage occurs; then battery power takes over until utility power is restored. Should utility power be off for an extended period of time, eventually the battery will drain completely
Double check to make sure you wired your wall switch timer properly.
Make sure there are no loose wiring connections.
Even though you purchased a new replacement timer wall switch, it could be a manufacturer's defect.
Has your home electrical system experienced any signal spikes? Electronic components are very sensitive to impulse spikes/surges and can be damaged very easily.
If you are experiencing surges or spikes, perhaps investing in a whole house surge protection system (Intermatic IG series) would be the way to go as well. It'll protect all your electronic devices and appliances through-out the house.

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.

What color plug where i ve got three colors blue,red,black


If I understand correctly, you are replacing a switch with the EJ500 timer.
You mention a 'plug'

The EJ500 has 3 wires: Black Red Blue.
If you are replacing a single-pole switch:
The switch has 2 wires, one of these wires is the Hot-from-breaker and the other wire goes to Load:
Timer-black connects to Hot-from-breaker.
Timer-blue connects to wire-going-to-Load.
Timer-red wire is capped off. Red is not used for single pole switch.
If you connect wires and your lights blink, then you put the red wire where the blues wire should go.
If you connect wires and lights do not operate, try reversing the blue and black wires.

I posted images of EJ500 wiring (the Intermatic EJ500 and ST01C have identical wiring
http://waterheatertimer.org/ST01C-program.html#ST01C

If you are replacing a 3-way switch, the wiring is more complicated.
The EJ500 can not replace a 3-way switch wire-for-wire.
Diagrams on link above show wiring for 3-way.
Add a comment if you need more help.

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.

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.

Timer quits shutting the lights off and time flashes 12:00AM


Intermatic is a reliable mfg. if you have a it wired to directly to a light and only a light, you most likely have a defective timer. Bring it back and purchase a rotary timer with on-off switch. more reliable. I too installed the same type of timer and went through 3 before installing intermatics rotary timer/switch.
