SOURCE: Changing Pool Timer

As long as you get a new timer that is 220/240v and is the same amperage or larger, you should be fine. Wiring would be the same.

SOURCE: Install a timer to control pool operation

Another option would be to get an electronic timer like the Intermatic P1353 that has 3 circuits on it that you could program to cut on and off at different times. For example, you could have one circuit that controls the pump and turns the pump on, then the second circuit would turn on the booster pump at a set time after the filter pump had come on and then the heater could be set to also run at a preset time after the pump circuit was activated. Since the pump, booster and heater are all 220, it's a straight forward hookup with everything in one timer box.

The lights, as stated before, would be on a separate circuit (110) and have its own timer or photosensitive eye set in line.

SOURCE: hello i hooked up a t104 timer to a 220 pool pump

I assume it's an Intermatic T104. I believe this has a 230V motor, which is best for your application. Since you only have 2 hots and a ground I assume you're only switching one leg to the motor. That's why the timer won't run. It need 240V to run the motor. You need 5 wires. Two "hots" coming in, and two going out to the motor along with your equipment grounding conductior (green). This will disconnet all power to the pump when off. Pay attention that you put the two incoming leads on correct terminals which I believe is #1 and #3. That's because those terminals also power the clock. Then connect the motor to #2 and #4 which go to the motor. 1 closes to 2 and 3 closes to 4. The equipment grounding conductor connects to the GR terminal (Green)

Check timer wiring.
And
Check that timer is getting voltage.

I write complete answers, and know the GE timer line.
Open links to illustrate discussion.
Aug 2011, Jasco does not show a manual for 15351 timer.

They show 120V 15350, which is identical to 120V 15306.

That makes me believe that 240Volt GE15351 is identical to 240V GE15307.
BUT the 15351 might be a DPST with NO and NC terminals >>> add a comment if your instructions say anything about NO NC terminals.

If 15351 and 15307 are identical, then your wiring is 100% correct, assuming you connected hot leads to terminals L and 1.
http://waterheatertimer.org/images/GE-15307-wiring-250.jpg
http://waterheatertimer.org/GE-timers-and-manuals.html#15306

Checking details:
1) You checked that terminals L and 1 are not connected by a brass bridge.
The 120Volt timer comes with a brass bridge across L and 1
2) Timer mechanism is attached to enclosure with 2 screws. Remove timer mechanism from enclosure, and compare back of your timer with following image to confirm timer is DPST.
http://waterheatertimer.org/images/IMG_9334-GE15307-500.jpg
3) Test 10-3 wire from breaker box. Test each wire to bare ground to confirm the hot wires. Then test each hot wire to other wire to confirm neutral wire. Tape tester leads to wood sticks to keep hands away from power and stand on dry boards.
4) Read nameplate on motor to make sure it is single-speed 240Volt.
5) IF motor is 2-speed, then look at wiring diagram and then add a comment with that information.
6) If pump motor trips breaker when connected directly, then pump might be shorted out. Double check wiring diagram on pump.

7) Take photos of problem. Post photos on flickr. Then add a comment with links to photos so I can see wiring diagrams, for possible help.

I need help to install pool pump to mechanical intermatic timer switch GE to replace the digital control.


Question is not clear.
Add a comment with missing information for exact wiring diagrams.
Voltage is not known.
Timer model numbers are not known.
You have two timers.
You are replacing unknown electronic timer with unknown mechanical timer.
Intermatic timers and GE timers are different companies, and each makes many different timers
Each box timer has identification on inside of timer door.

Pool pump starts randomly (as if there is a short) even when it is not set to start and stop. Otherwise works fine, not sure if I need to replace unit or dissassemble and clean or ????? T21004R


Sounds like 240Volt WG1573 clock motor has gone bad and needs replacement. But more checking is needed.

You posted under T2100-4R which is 60 amp Intermatic control panel with a single T104M 240Volt timer mechanism.
All Intermatic timer mechanisms can fit into same control center, so you can possibly have different timer mechanism inserted into the T2100-4R control center.
The control center can have up to 4 circuit breakers.
Instruction manual shows that timer can also have fireman's switch that is wired to pool heater and causes pool heater to turn off 20 minutes before pool pump turns off.
http://www.poolandspacontrols.com/products/mechanical%20controls/60%20amp%20pool%20and%20spa%20control%20panels.aspx

(1) First thing: If you have T104 mechanism, do a troubleshoot run-down to see if trippers, clock motor, or wiring are suspect:
http://waterheatertimer.org/How-to-troubleshoot-Intermatic-timer.html

(2) Next would be to check the circuit breakers for loose wires, burned connections, or the smell of burning or crackling sound that says breaker is loose on the busbar.

(3) Check for loose wiring on T104 and test circuit:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
(a) Push the manual override lever to OFF position and test across terminals 1 and 2 and then across terminals 3 and 4 to make sure timer is turning off power to pump. Both tests should show 0 volts.
(b) Push manual override lever to to ON position and repeat test above. Both tests should show 240 volts.
If the test fails, then buy new T104M timer mechanism.

(4) If the T104 timer is turning off both lines in the 240Volt circuit, then pump cannot turn on since neither wire is Hot.
However if your T104 timer is actually a T101 timer or if timer has different wiring, where timer is turning off only 1 leg and not both legs of 240Volt circuit, then pump has one hot wire available and a short to ground could cause pump to turn on unexpectedly.

I'm hooking this up to a pool,quickset 10x30. this is not working for me help.......


What exactly are you trying to do?
Please explain in detail. For example, (I'm trying to connect the pool pump to the timer and set the pump to run 12 hours per day, on for an hour off for an hour, but I don't know how to to set the pins.)
So the more information you can provide the easier it'll be to help you achieve exactly what you're requesting.

My Ge Mechanical Time Switch (Model number 15087) is losing time. Is there any way to adjust the timer so that it keeps correct time?


There is no adjustment if timer clock is running slow.
Timer clock motors run slow when the motor starts to fail.
There are no replacement clock modules this timer.
Buy a new timer at Home Depot, and swap out insides of timer using 1/4" hex nut driver, and then return defect timer in new box.

Pentair pool pump vs 3050


These pumps should not be hooked into an intermatic mechanical timer. It should always have power supplied to it, meaning it should be installed to the line side of the power supply. Scheduling is done either in pump itself or thru an external controller such as a suntouch or easytouch controller, etc. When you have it wired into a timer like intermatic, power is interupted to the pump every day when the timer setting is for off. It is very hard on the drive of this pump, it does not like it, and will shorten the life of the drive. The pump was designed to always have power supplied to it, even when it is not scheduled to run. This may be the problem you are experiencing. HTH
