Question about Intermatic T104 24h 208-277v Mechanical Time Switch

Open Question

I set the time and the clock does not run

I have intermatic Model T104P3 timer to turn the pool pump on and off. I can see the gears moving in the back part of the enclosure but not the gears in front. The timer does not keep the day of day - I set it and it does not move.

SOURCE: i moved the time pinter by accident. now the timer

Did you mix up the pointers? One of them is for off and one for on. Dont know any other reason. If the timer is working all the pointers do is manually trip the lever as it comes past. On and Off should be stamped on the pointer.

The T-104 is a 240Volt timer that will not work for 120V circuits
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

The above link gives you information about the T104 T103 T101 in case you need to buy another timer
The difference is the voltages on the lines and voltage of the clock

1) How to sort out what you have:
-Which circuit breaker operates the timer and pump? If your circuit breaker is 240, then the pump is 240 and the timer is 240 so you most likely have the T-104
-To double-check: turn off the power and look at the name plate on the pump >>> the name plate will show voltage of the pump
-If breaker is 120, then you have T-101 that has three terminal screws inside the timer, or you have T-103 with 5 terminal screws inside the timer.

OK that's the basic information:
You say your trippers don't work.
Does the manual override work?

2) If the manual override does NOT work when you click it back and forth, and the unit has electricity, then the timer is probably bad. You can buy a new timer, and swap out the insides with old timer without replacing box.

3) If the manual override DOES work, then best news of all ... you may need new tripper pins

The timer wiring provides power for the clock itself. If it is incorrectly wired or if the clock is not working, the pump will not turn on.

SOURCE: Can you send a scematic

No. I don't have a wiring schematic without knowing what voltage you are using, specifically what Intermatic timer you have, specifically what wires you have coming from breaker box, what wires are on the pump, and what pump rating plate says, what the wiring diagram shows on side of pump, whether you are wiring a 2-speed pump to a single-speed timer, specifically what is the polaris timer clock, and why this pump needs two timers if that's what you mean.
Add a comment with specific information so electrician is not guessing.

What position is lever on intermatic pool timer t104p3 for timer to work?


Lever automatically moves back and forth as trippers pass.
Move lever to ON position, move to the right.
If timer dial is not rotating, then check wiring, or replace clock motor:
If timer worked before and stopped working, but dial still rotates, the trippers are worn down, replace trippers:

Pool pump clock


T104M used WG1573 clock motor:
http://waterheatertimer.org/How-to-troubleshoot-Intermatic-timer.html
http://waterheatertimer.org/How-to-replace-Intermatic-clock-motor.html
http://waterheatertimer.org/Intermatic-trippers-and-parts.html#T100
The timer mechanism has metal gears, while the clock motor has plastic gears. If the metal gears get dirty and bind, it will strip the plastic gears.
Turn off power, pull timer out of box, Clean out timer with compressed air, and spray WD40, add a bit of white grease to lever where trippers make contact, then replace clock motor ... and buy another set of trippers to have on-hand since they are designed to wear down so timer will last longer.
If timer body is broken so dial does not rotate, then buy new T104 and snap new mechanism into old box. Buying whole T104 with enclosure is cheaper than buying T104M mechanism only.

How do I connect my Jandy AE-TI heat pump to my intermatic T104P3


1) Copy following link for wiring illustration ... assuming timer is supposed to control pool pump:
http://waterheatertimer.org/images/T104-to-contactor.jpg

2) T104P is 240Volt (208-277V) SPDT timer in P plastic outdoor enclosure.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T104

3) Jandy AE-TI is 208/230V pool heater.
http://www.bestbuypoolsupply.com/media/aemanual.pdf

4) Page 13 of Jandy manual shows single-phase residential wiring diagram.

5) First of all, power to main contactor is not interruped by timer, since this powers 24Volt transformer that controls the chip board and general operation.

6) The timer is connected to 'Auto-heat contactor.'
The confusion is what Load connects to this contactor? The water pump? Load is shown on diagram as 'pump time clock.'
I assume the load is the PUMP??

Intermatic t104p3 pool timer will turn pump ""ON" with Manual Switch but will not shut "OFF" using Manual Toggle. Pool store showed me how to remove and look at the contacts on...


Thank you for including model number so answer can be accurate as possible.

T104P3 timer works with manual override so timer is basically sound.
Clock dial rotates and keeps good time, so WG1573 240Volt clock motor is good.
Trippers do not click on-off lever, so trippers are suspect.
Trippers are made to wear down so that timer mechanism lasts years longer.

Order extra clock motor and trippers at Grainger

How do i reset and restart my intermatic T104p3 after power outage? the gears don't turn and the timer is new.


You should be able to grab the timer dial and pull towards you, now spin either direction to the desired time. If you are at a time where the clock is about to turn on or off you may have to move it a little bit more or less
