Question about Hardware & Accessories

1 Answer

T104 intermatic timer being used for parking lot lights. Timer works only half way through cycle. Once it cuts on it stays on and then timer stops. Here's the wiring scenario: incoming wires from breaker panel brown wire (277volts), rust color wire(0 volts), & white wire(0 volts). Incoming from lights red, black & white wire. Attached brown and rust color wires to terminals 1 & 3 respectively. Attached black and red wires(LOAD) to terminals 2 & 4 respectively. Wire nut both white wires together. All four terminals read 277 when power is on and the white wire from the lights reads 10volts(suspect this is residual voltage).

T104 is 208-277Volt timer.
Wiring is correct if timer worked fine before.

Quick troubleshooting:
Click manual override and see if lights turn on-off.
If manual override clicks clean and crisp, and lights turn on-off, then timer mechanism is working.
If manual override is sluggish and hard to push, and timer mechanism is rusty or dirty, then timer needs to be replaced.
Buy another T-104, swap out insides without changing box. Put wires back as before.

If the dial stops moving, then replace clock motor.
T104 uses the t-100 series 208-277 clock motor that Grainger sells for around $20

If the dial operates fine, the trippers may be worn out.
Grainger also sells T104 tripper

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:

Intermatic t10004rt3 pool timer cycles a loud hum/buzz noise like bad contacts or relay


T10004R control center has one T104 240V timer, with extra space for another timer or freeze control etc.
You can clean up the timer and replace clock motor to stop most noises.
The T104M (M for mechanism-only, snaps into the control center enclosure.
The T104 also snaps out of enclosure using thumb spring located top inside box.
Take image of wires before disconnecting from timer.
The T104 is identical to WH40, same parts, same trippers, same appearance, except with different override lever.
Here are photos of WH40 showing how to take apart timer and clean it, also with links identifying replacement parts:
http://waterheatertimer.org/Photos-of-WH40-timer.html
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T104

If you need to replace timer, it is cheaper to buy the ordinary T104 that comes inside a box and can be snapped out, instead of buying T104M (M for mechanism-only)

E10694 timer


Scroll down and identify timer:
http://waterheatertimer.org/Intermatic-timers-and-manuals.html
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

E10694 is imaginary number applied to all sorts of intermatic timers sold by folks who want their timer to appear unique and rare on internet. It has been used for T101 120V timer, T104 240v timer, T170 series timer with day-skipper, and also with 'cycle' timers... except all timers with rotating dial could be called cycle timers, but 'cycle timers' are normally timers with less than 24 hour rotation period.

Intermatic pool timer instructions


Timer is not identified. Do you have control center that controls heater, pump etc, or individual timer that controls pump?

Is this a new installation? Or did timer work before and stop working? What voltage are you working with?

I have an Intermatic 24hr. Dial Time Switch box (mod.T104R) that is connected to my in-ground spa by a pneumatic with a rubber push button located on the spa deck. I pushed the button a couple of days ago...


You have 240Volt T104 Intermatic timer.
The clock works, and the spa works so voltage to the timer and spa are good.

You have push button control located on spa, and it stopped working.

1) The push button does NOT control the timer. T104 is mechanical timer, and the push button cannot activate the switch contacts, and there is no solenoid inside the timer that gives that option.
The push button is a separate problem from the timer.
So replace the push button.
Example push buttons at Grainger:
http://www.grainger.com/Grainger/wwg/search.shtml?op=search&N=10866&in_dim_search=1

2) Timer problem.
What does the timer do?
If you have a push button, why do you need the timer?
T104 is mechanical single-channel non-electronic timer, and cannot override the push button once the push button is OFF. They make industrial timers that can perform multiple functions, but T104 is not in that category.
This makes me think the timer dial does not have trippers mounted on the dial, or the trippers are worn down.
Maybe the timer function is by-passed. Maybe all wires are on terminals 1 and 2.
Check how the timer is wired, and then add a comment.

T104 clock stopped running. must now use switch


Yes, you can replace the timer motor to solve the problem. For the Intermatic T104 you'll need to purchase the 208/277 volt timer motor. Part number is WG1573.
http://www.aplussupply.com/intermatic/timer.htm

If you don't want to mess with replacing just the timer motor you can purchase a new timer and swap just the guts with the old timer as long as the existing enclosure is still in good shape.

I set my T104R3 on and off clips to desired times and turned the timer on. At set time the timer went off, but the clock stops and does not continue and turn on at the desired time.


The T104 timer is miswired when it does things like that. The 240 volt clock motor is internally connected at the factory to terminals 1 and 3. That means that one of the incoming (line) 240 volt wires (pick one) _must_ be connected to terminal #1 and the other _must_ be connected to terminal #3.

The outgoing (load) 240 volt wires are connected to terminals 2 and 4.

The Intermatic wiring diagrams leave a lot to be desired. I wrote the following tip to help clarify intermatic T103 and T104 timer wiring, I hope it helps:
