This timer only works with incandescent light bulbs. It does not work with CFL's (compact flourscent light bulbs). Intermatic model ST01C will work with CFL's and LED's. I ordered one today from They had the best price.

Timer has worked in the past as programed. However, upon resetting timer to correct time of day then setting "ON" & "OFF" porch light seems to come "ON" two hours...

I test timers.
Timers go bad.
EJ351 has 1 year limited warranty.
Wiring is correct or timer would not operate.
Bulb is good.

I would reset timer again and re-program.
If timer still will not function, then timer has gone bad.
Following page has manual:
Reset instructions: Move the control lever to the OFF-CLEAR position for about
20 seconds. The red indicator light will go off and any previous
time settings will be cleared from memory.

Superswitch programmable wall light switch - when timer is in off position lights glow dim when using energy saving bulbs.

Manual say 'incandescent' light bulbs only.

What can I control with my EJ351C? The EJ351C timer is to be used with standard base incandescent light bulbs only! It should not be used to control lighting such as:
  • Compact Florescent
  • Energy Saver
  • Flood lights
  • Halogen
  • Mercury Vapor
  • Christmas lights
  • Candelabra bulbs

I have the EJ351 model and when it is programmed the lights come on at the desired time; but it never turns the lights off. Manually it works fine and turns the lights on and off.
See the manual

I think you forgot to set the OFF time that corresponds with the ON time, or your on-off times conflict with each other

Make a chart of you on off times

Clear programming
After setting present time,
Rotate dial clockwise to first ON time, push button in to set ON time
Rotate dial counterclockwise to first OFF time, push button to set OFF time

Repeat this up to 8 times >>> but don't overlap your ON-OFFs

There is also a way of setting it by simply turning the light on and off at the desired time. Can yu help?


The manual says:
"To automatically program, letting the switch
timer "record" your ON/OFF activities over a 24-hour period,
storing them as programmed settings:

Move the control lever to the OFF-CLEAR position for about
20 seconds. The red indicator light will go off and any previous
time settings will be cleared from memory.
Move the control lever to the ON position. The Red indicator
light will start flashing.
Press the dial as an ON/OFF switch to turn lights ON and OFF
at the ON and OFF times you desire for the first 24 hours.
At the end of the 24-hour period, the switch timer will be programmed
and the Red indicator light will stay ON, indicating
that the switch timer is in AUTOMATIC mode."
