Can't program, won't turn lites off


"If you need more programming assistance, request form #158ET9311 " from Intermatic.

Or call Intermatic: 815-675-7000

Manual shows example programming on page 17-18:
http://waterheatertimer.org/pdf/Intermatic-et70415cr.pdf
The instruction manual for this timer does not have step-by-step programming.
There is example programming on page 17-18, but it shows one example.
The timer manual doesn't have step-by-step because the timer prompts the user as the user is programming timer.
As a result, it is difficult to know what step was missed.
It is equally difficult for expert to know what went wrong.
In addition, the timer offers choice of 24 hour or 1-week or 365 day programming.
Also the timer offers choice between 'astro' dawn-dusk' or 'fixed' programming, 'pulse' bell-ringing programming, and 'interval' programming.
And then there are additional programs available for individual days throughout the year if you choose 365 day operation.
Add on top of that, the timer has 4-channel operation where each of the 4 different relay circuits are programmed separately for each of the options mentioned above.
For these reasons, I recommend contacting Intermatic about this timer.

We've lost the instruction manual for our light switch timer so don't know how to reprogram it. Directions, please!! We've just replaced the battery.What buttons do we press in what order to...


Question posted under Intermatic timer:
Open following link to identify timer and download possible manual:
http://waterheatertimer.org/Intermatic-timers-and-manuals.html

IF Intermatic timer stopped working because battery failed, then all that's needed is to reprogram current time, because the original timer programs you set are stored inside timer forever until timer is manually reset using reset button.

If you have Intermatic ST01C timer, then open following page for ez instructions:
http://waterheatertimer.org/ST01C-program.html

If you need help programming specific timer, then get as far along in manual as possible, and then add a comment.

If you have different brand timer, than each brand has link that shows on Intermatic page.

I can't download the instruction manual from Intermatic's website. I have a EJ500C timer and want to know why they caution against using it with CFL's and how to program it to shut off...


EJ500 7-day or astronomic timer is incandescent light bulb timer.
Different timers have different Load ratings.
Intermatic ST01C timer can control CFLs.
Aube timers have same wiring capability as Intermatic, and offer CLF control, but you have to choose either astronomic timer, or 7-day timer.
Open following links for manual and timer information.

Cannot figure out how to program a 2 speed pump Model T21004R


T21004R is Intermatic control center with T104M 240Volt mechanical timer mechanism.
http://www.poolandspacontrols.com/products/mechanical%20controls/60%20amp%20pool%20and%20spa%20control%20panels.aspx

Typically the T104M timer is not used to control a 2-speed pump, simply because the timer doesn't have NO NC terminals or programming capability.
Add a comment any time for more help.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

Typically, if you are controlling a 2-speed pump, then a different mechanical timer is installed into the T21004R control center, OR the P1353 programmable timer is installed.
Open following links to identify P1353 and download instruction manual.
http://waterheatertimer.org/Intermatic-trippers-and-parts.html#P1353
http://waterheatertimer.org/images/P1353ME-2-speed-motor-500.jpg
IF you are programming P1353, read instruction manual and get along as far as you can, then add a comment saying where you are stuck. Use MODE 2 for 2-speed motor applications.

How do I program this timer?


T104R3 is ordinary 240V T104 timer mechanism inside a beige metal weathertight enclosure.
Put ON-OFF trippers on dial, lift and rotate dial until current time lines up with silver pointer.
Reset current time after power outage.
Open following links for T104 Instructions:

I have digital programmable timers (Model DT121 and Model DT11) that will accept programs, but won't turn the attached lamps on and off at the programed times. The batterys are new and I've had them...


DT121 Manual
http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/dt121c%20-%20english.ashx

All Intermatic manuals
http://www.intermatic.com/customer%20service/instruction%20manuals.aspx

Intermatic does not show DT11
Intermatic shows the DT121 is no longer available

If the display shows and you can set programs, then the battery is good.
Does the manual override work? This indicates whether the timer on-off switch operates.
If manual override does not work, then I discovered that timers are no longer any good

Programming:
Set present time
Then set ON time for program 1
Set OFF time for program 1
Then set ON time for program 2
Set OFF time for program 2
Most timers will not function if there is a conflict in programming > for example Program 1 says ON at 6 and OFF at 7 and Program 2 says opposite or has overlapping times
When events are set, press SET once > this will put timer in RUN mode

If manual override works, and you set programming correctly, but timer does not carry out instructions, I guess the timer is no good.

Intermatic has 24 hour timers with 2 on-off per day
http://www.intermatic.com/products/timers/consumer%20indoor%20timers/lamp%20%20appliance%20timers.aspx
Intermatic has 7-day digital timers (all digital timers today are 7 day where you select the day that each program works)

Intermatic ej351, i ned the instructions for resetting the timer. to turn it on at 630pm and off at 100am pleae


1) Use this procedure to automatically program, letting switch timer "record" ON/OFF activities over 24-hour period.
-Move control lever to OFF-CLEAR for about
20 seconds. Red indicator light goes off and previous
time settings are cleared.
-Move control lever to ON position. Red indicator
light starts flashing.
-At 6:30pm, manually press dial 'on' >>> then at 1:00am manually press dial 'off'
-At the end of 24-hour period, switch timer is programmed and Red indicator light will stay ON, indicating
switch timer is in AUTOMATIC mode.
2) Or you can manually program times using instructions from page 1 of manual:

Need instructions to program Intermatic Model #E140C wall switch timer.


Do you mean Intermatic E104C box-type timer? Intermatic does not make E140C

Manual says "refer to programming instructions on time switch door"
http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/et104c%20-%20english.ashx

Manual says timer has 8 events per 24-hour day ... 4 'on' events and 4 'off' events. Normal operations, selectors are set to AUTO and RUN.

Using sketchy info from manual about programming:
Set sliders to MANUAL & TIME/SET
Press EVENT for event 1 ... set hour and minute using HOUR & MIN buttons ... this will be 'on' time
Press EVENT for event 2 ... set hour and minute ... this will be 'off' time
Set all 8 events ... 4 'on' and 4 'off'
Move sliders to AUTO & RUN for timer operation
