If I understand correctly, you are controlling 240V water well pump with Intermatic C8866 Repeat timer.

So you must be using pump to irrigate, and want to turn pump on at certain times of day for short periods ... and want this schedule to repeat continually non-stop.

1) The c8866 repeats the same program every 4 hours so this is good choice for irrigation and it just turns the circuit on-and-off so it works fine with well control box (unless you want more complex programming).
Many types and prices of cycle timers
More cycle timers

Let me give a buckshot answer and see if I hit one of the targets you have.

2) C8866 according to manual:
a) You have on-off trippers
b) First ON tripper turns on load for 32-40 seconds
c) Each additional ON tripper will lengthen ON time by 30 seconds

3) To lengthen ON time: add successive ON trippers into dial. Each successive tripper adds 30 seconds. Let's say you want ON time to be 3 minutes, you need 6 successive ON trippers.
Maximum timer setting is 240 minutes, so your ON-OFF program repeats every 4 hours.
10 Tripper pins come with timer.
Buy more pins at Grainger for 2.69

4) Did you say the clock stops running after hitting the tripper? If so, maybe you need a bit of grease on the pins ... or a new clock motor? Buy clock motors at Aplus
5) Review the wiring
Hots from Breaker connect to COM and CLOCK poles
1 Hot to Load connects to NO normally open pole
Other Hot to load connects to CLOCK pole

6) You can reverse ON-OFF programming by the following:
Change Hot to Load from NO to NC pole and this will reverse on-off programming

Wire a time switch to a pool pump motor


Yes.
240Volt can be turned ON-OFF by cutting power to one of the two 120Volt wires in the 240Volt circuit. You need Neutral wire for 120V, while 240V does not require neutral wire.

Hi - My Intermatic T101P3 timer motor stops after it turns off the pool pump. I have one start and one stop time in a 24 hr period. I have to manually start the pump at the timer in the morning,...


Sounds like the clock leads are on the wrong posts, or at least the hot one is. If if was moved to the load side then manually starting the timer will also power up the clock motor. As soon as the clock trips the off timer, the pump and the clock motor are both off. Examine the clock leads to the wiring diagram inside the clock box cover to ensure they are connected correctly. I bet you'll find one of the wires is misplaced.

1) Order 240V T100 series clock motor.
http://www.grainger.com/Grainger/timer-accessories/timers/electrical/ecatalog/N-8hi
http://www.amazon.com/Intermatic-Clock-Motor-Leads-WG433-20D/dp/B0031DOHLG

2) Order extra trippers too since they are designed to wear down so they don't damage tripper lever.
Put dab of white (bicycle) grease on the tripper lever.

3) Turn power off.
Mechanism snaps out using thumb-spring located inside box at top.
Clock motor is held with two star-screws. Buy bit at auto parts store.
Clock motor wires attach to terminals 1 and 3
Reattach terminal screws very tight against copper wire and make sure wire-insulation is not caught under screw clamp.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
To re-set current time, lift and rotate dial until current time lines up with silver pointer.

4) See next generation of Intermatic pool timers that snap into same box.
New timer controls 3 separate circuits with different schedules for each circuit, so the single timer can replace both mechanical timers. Wiring is complicated, programming is complicated. I am still reading the manual, and it makes sense to me, so you can trust fixya to help in event that you replace your timers next ten years.

You have C8866 repeat cycle pump, that repeats the same program each hour.

Your well pump is 240Volt which is why you have two Hot wires.

One Hot wire connects to COM terminal.
Your Neutral wire connects to Clock terminal.
This will power the clock motor.

One hot wire to Load connects to NO normally open terminal.
This terminal turns ON when timer turns ON.
NC terminal is ON at all times, EXCEPT when timer turns ON, and then NC terminal turns OFF

Your second Hot wire runs directly to pump and does not connect to timer.
See diagram below:

Don't know what is it used for,and how it operates?I don't have any instructions for it.


You posted under T101 timer.
Most box timers have model number and instructions pasted on inside of door.
Instructions can seems a foreign language sometimes.

If your timer is different than T101, then add a comment with timer number.
I have extensive files on timers.

Box timers are generally used for heavy amperage loads like outdoor lights, swimming pool pumps, water heaters, parking lot lights and lighted outdoor signs.
They are surface mounted near breaker box, or in attic or basement, or garage.
Box timers are used in schools to ring bells, and inside factories to run processes and fans.
Some are complicated electronic devices used to control machines with one second precision.
Mechanical box timers are noisy when turning on-off, so are generally not installed in living area of house.

T101 timer is least complicated of any timer.
It is used for ordinary household 120V circuit.
Timer has 120Volt clock motor, and controls 120Volt circuit.
For example 120Volt water heater, or 120V grow lights, or aquarium, or any application up to 2 horsepower, for example timer can be located inside garage to control outdoor lights.
T101R is raintight outdoor box, with rubber gasket on door that seals tight when closed.
Raintight boxes are installed outdoors to operate 120Volt spas and pool pumps.
When box timer is rated for indoor, there is no rubber gasket on door, and that box is called NEMA 1 enclosure.
My local Lowes sells T101 T103 T104 > and each is for slightly different purpose and each wires differently.
Link below shows wiring and manuals for T100 series timers.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101

Here's how T100 series timer works:
Lift and rotate yellow dial until current time lines up with silver pointer.
Clock motor rotates dial as time passes.
Clock motors are accurate for years, but current time has to be reset after power outage.
ON-OFF trippers are placed on outer edge of dial.
Trippers push a lever, and lever turns circuit on-and-off.
ON tripper pushes lever one direction.
OFF tripper pushes lever opposite direction.
Each time lever is pushed, manual-override lever clicks back and forth with audible sound.

I am not sure on how to wire the freeze protection wires to the time clock. i know they must go to the load side of the clock for the main pump but will this reverse the power back into controls and short...


Here's a 240V diagram with clock timer and freeze control:
Add a comment if explanation does not fit your exact timer:

geno_3245_67.jpg
See image full size:
http://waterheatertimer.org/images/Freeze-protection-500.jpg

Here's how freeze control works:
Freeze control is like regular timer, except it turns ON by thermostat instead of time-clock
Freeze control turns ON pump whenever thermostat kicks on.
Both clock-timer and freeze-control are wired to pump in 'parallel' so to speak.
Think of it as having two controls wired to same pump...
Both controls can turn pump ON-OFF.
If one turns ON, and other is OFF ... then pump is ON.
If both are ON, then pump is ON ... and electricity just flows around on extra wires.
If both are OFF, then pump is OFF.

Say it's below freezing all day.
Freeze control circuit is ON all day ... pump is ON all day
Clock timer turns ON > but circuit is already ON, so timer just opens more wires for electricity to flow around on.
When clock timer turns OFF > freeze circuit is still ON because it's below freezing ... pump is still ON.

240V wiring:
Power leads coming from circuit breaker go to terminals 1&3 on clock-timer
Same power leads connect to freeze-control-black and freeze-control-red.
Or connect freeze-control-black and freeze-control-red to terminals 1&3
This action puts power to clock and power to thermostat

Pump wires connect to terminals 2&4
Same pump wires also connect to freeze-control-blue and freeze-control-yellow.
Or connect freeze-control-blue and freeze-control-yellow to terminals 2&4
This action connects pump to both freeze-control and timer.
When either clock-timer or freeze-control turn ON, then pump turns ON.

Just installed the new t-104 and the clock runs slow


The clocks on Intermatic timer run on-time for years.
If this a new timer >> then buy another one, and swap out the insides without changing the box, and return the bad one.

Voltage variation will not affect clock speed. The only electrical thing that affects speed would be the cycles. Your household has 60 cycles. The clock motor is 60 cycles.

When you connected wires, the wires fit under a metal clamp and the screw pushes the metal clamp down against the wire > only copper wire should be under that clamp > if some insulation is also under the clamp, then the contact might not be 100% all the time, which would stop the clock. Check that all your wire are down tight.

If wires stop in a junction box before arriving from breaker box, there might be a loose connection in that box. Trace back your line, especially if this is a pool control with a junction box.

A shorting breaker can stop voltage from time to time, making it appear as if the clock is slow. If one leg of the 240V stops, the circuit stops. You can check breaker for loose screws. Does breaker feel warm? Is there a crackling sound when you jiggle breaker. You can put your timer 240 lines on similar sized 240 breaker and see if clock runs slow ... that would indicate whether the problem is clock or breaker.

If timer is old, the plastic clock gears can get worn. The metal timer gears rust or clogged with dirt. Snap out the insides and inspect for rust and dirt. Use a little WD-40. Turn off power since WD is extremely flammable.

Snap the manual override back and forth. Does it snap crisp? Or is it sluggish? The clock motor turns the dial until the tripper encounters a metal lever. The Clock keeps pushing the tripper until the tripper clicks the metal lever >>> which happens to be the same lever the manual override is connected to.

So if the manual override is very hard to push ... ... a sluggish manual override might slow the clock. You might put some grease on the lever where the trippers touch.

Finally, the clock motor can go bad.

The pump stopped working today. There is power to the pump and the circuits did not shut down. I think the clock could be bad. It has not moved so I feel the problem is the clock. the pump is new.


If you move the manual lever to the ON position the pump should turn ON. If the pump turns ON manually and the clock is not moving as you say, then, yes, the clock timer motor is bad.
