Can you turn off the circuit by moving the on/off lever manually, or by turning the time dial manually? Does the time dial rotate and keep time? If not, I'd double check the wiring diagram on the door of the enclosure first.

Intermatic HB35R timer has its current time correctly set with both on and off trippers also set correctly.....Tier will not come on @16:30 as programmed......Have to use manual switch to turn on and then...

Place green tripper at ON time & red tripper at OFF time. Twist timer dial one or more times until current time of day is aligned on pointer. When twisting timer, the trippers should actuate the manual knob on and off each time you make a full turn. Make sure trippers are fully inserted so that they engage the "catch" of the override knob - if not they will not cycle power to the output.

How wiring intermatic timer t51211bc i have one circuit control by timer ....and one circuit contro by photocel indor lite and outdoor lite

T51211BC is 120Volt timer that can be wired many different ways because there are two internal relays, and each relay has NO and NC terminals. One relay is controlled by timer dial trippers, and other relay controlled by dawn-dusk photo eye

Timer wiring cannot be fully explained with words.
Below is basic hook-up for your 120Volt wiring application, and then you can use a tester and experiment with the knob settings, and tripper settings.

1) You have 4 cables:
one cable from circuit breaker box;
one cable going to photo control;
one cable going to outdoor Load (lite);
one cable going to indoor Load (lite).

2) Cable from circuit breaker has 2 wires:
Black Hot wire connects to terminal 1
White Neutral connects to terminal 2
This will power the clock motor and timer relays.

3) Photocell has 3 wires:
Black connects to terminal 1
White to terminal 2
Red to terminal 3.
Photocell turns relay on-off for Circuit B
Do not mix different size wires under same screw terminal, or smaller wire will come loose over time. Also do not mix stranded wire and solid copper under same screw terminal for same reason.

4) Terminals 4 thru 12 are 'dry'.
Dry terminals receive no power when power is applied to terminals 1 and 2.
To put power on dry terminals, so that Load will have power, attach Black hot wire from breaker to terminals 9 and 12.
So add a jumper wire from terminal 1 to terminal 9 and another jumper wire from terminal 9 to terminal 12.
120Volt power is now connected to terminals 1, 9 and 12

5) Circuit B is dawn to dusk for outdoor Load.
Outdoor load cable has Black and White wire.
Connect outdoor Black wire to either terminal 10 or 11.
To test which is correct for your application, set switch to Auto, and then test across terminals 12 and 11, and across terminal 12 and 10. Repeat test after dark. Rotate knob B to each position and repeat test.
Connect outdoor White wire to terminal 2, and this will complete the circuit.

6) Circuit A is Dusk ON and timer OFF
Indoor cable has Black and White wire.
Connect indoor Black wire to either terminal 7 or 8.
To test which is correct for application, set switch to Auto, and then test across terminals 9 and 8, and across terminal 9 and 7. Repeat test after dark. Rotate knob B and repeat test.
Connect outdoor White wire to terminal 2, and this will complete the circuit.

Why do I need to use the Jumper? Does the timer close the circut on the nutrel side only or does is close both ?

EH10 has four screw terminals: 1 2 3 4
EH10 has two screw terminals exclusively for electronic clock motor.
These terminals connect exclusively to clock ... there is no internal jumper that passes power to another terminal.

Terminals 2 and 3) Black Hot lead connects to two terminals. Hot connects to terminal 2 and to terminal 3 ... so you put a jumper wire between terminals 2 and 3.

Terminal 1) All neutral or white wires connect to terminal 1, so there are two white wires on terminal 1.

Terminal 4
) Black wire going to 120V Load connects to terminal 4.

Contrast EH10-electronic-timer with T-101-electro-mechanical-timer. T-104 clock motor has two separate wires that connect to terminals A and 1. Electronic clock doesn't have those separate wires.

Your second question about closing the circuit.
When timer turns ON, it closes circuit between terminals 3 and 4.
So the Hot is closed.
Neutral is not closed, it is open at all times.
EH10 is SPST timer ... One single pole is opened-and-closed (SP), and timer completes action with a single throw (ST)

My paragon timing motors model 1015-00RSB are not timing as desired,how can i or guide me on how to programme and make schedule adjustments on it? Please help me

The Paragon 1015 timer is a 24-hour timer.
The tripper pins or tabs are built into the timer dial.
This timer has NO and NC terminals.
NO NC terminals mean the timer can control two different circuits.
One circuit would be ON when the other circuit is OFF.
When the timer turns on, the circuits change so now one circuit is OFF and the other circuit is ON.

If you have just one circuit, then the following instructions will help you.
If your timer controls two circuits, you can add a comment and I can help further.

OK, your timer controls one circuit.
Locate the tabs on the timer dial.
Push down all the tabs.
Now lift all the tabs for the times you want your Load to turn ON
So if you want the Load to turn ON from 7pm to 5am, then lift all the tabs between those times.
Now when the timer dial rotates, the tripper tabs operate an on-off lever that turns the Load ON and OFF.

Set current time of day
The timer has to be set to current time.
For example it's 6pm.
Grasp and rotate dial until 6pm lines up with the stationary red pointer

Skipper wheel:
The 1015 series has a skipper wheel that lets you skip days of the week.
On these days the timer program will not turn the Load ON or OFF
So if your regular schedule is ON from 7pm to 5am, then the Load will remain OFF for those times.

Set skipper wheel:
Locate day to be skipped on the small dial.
Raise the set screws for the days you want to skip
Raise set screw until it is tight, but do not force

After a power failure, current time of day has to be reset.

If you need more help, add a comment and I will assist.

If timer has been working fine up until now, you probably need a new tripper pin

If lever is worn out, then you need new timer.
You can but a T-101 and swap insides without changing box
The T-103 will also work because it has a 120V clock motor
The T-104 is a 240V timer and will not work
You can buy the replacement timer mechanism and swap out

When wiring new timer, put wires back the same as old timer
For T101 and T-103 wiring schematic, see following link

New 220 timer put in ,wont turn on.Vsiual chek working and its keeping time,switches look good but woont kick on?

I wish I knew the model number.
maybe the wiring is wrong, but different model numbers have different wiring.

I wrote a page on each the T-104 and T-1906 240V timers:
It shows the wiring for 2 common Intermatic timers

Now let's troubleshoot a bit:
You say the dial is rotating around.
And the dial has tripper pins in place.
What about the manual override? Does the manual override turn lights on and off?
If manual override does not turn on the Load, then your wiring is suspect.
If manual override works, then your wiring could still be wrong by one wire.

Check your tripper pins.
Are they attached and set exactly right?
Are you using both ON trippers and OFF trippers?
1565897.jpgThe OFF tripper pushes a lever. The lever is connected to Manual override. Click manual override to see if timer can turn Load ON-and-OFF

Up-vote if this information helped. Thanks for the feedback.

Clock does not work to turn pool filter on and off. do I need a new timer mechanism or clock motor

Things to check:

1) Is yellow dial rotating? If not, then clock motor is probably bad. T-100 240V time clock motor sells for $16 at grainger.
Also timer may not be getting 240V so check manual override.

2) If clock motor is turning, but manual override never clicks on-and-off, then pins are probably worn out. Buy pins at grainger

3) Does manual override work? Does it click crisp? If manual override clicks crisp on-and-off, and pool filter turns on-and-off normally, then a) the circuit is getting 240V and b) the timer mechanism is ok ... so clock motor is probably bad.

4) If manual override snaps crisp but pool timer does not turn on, then then circuit breaker could be bad, wire is loose, motor has gone bad
Test for 240 across poles 1 and 2
... or timer contacts are worn out & you need new T-104
See back of mechanical timer

5) If manual override is loose or sluggish, then you need new T104. You can buy a T-104, T-104R, T-104M etc ... and the interior body will snap into old box.

Note: Do not buy T-101 or T-103 as these have 120V motor.

You have wired it correctly assuming this is a 230V water heater. The timer should have come with the motor connected to terminals 1 & 3. You should be able to see two small wires coming from the rear. These are the motor leads. Make sure they are on terminals 1 &3 also. Check for 230V on the 1 & 3 terminals with the load off just to be sure you didn't accidentally reverse the line and load. Check to be sure timer motor is running. GOOD LUCK!

When my "off" time shuts off pool and timer. it short circuits the circuit breaker. Also, electrician installed the timer laying down to fit into breaker area, is this the cause or is this new timer...

The timer switching off has nothing to do with it's location, it has to be in the wiring, One of those wires is in the wrong place. It is sending the juice back to the ground or neutral. Inside your timer, you have a place for 2 or 4 wires? One in, one out, the switch completes the circuit, turns on, turns off, the white wire is in there to run the clock and complete continuity to the pump? which is 220 volts? If yes, then you are switching 4 wires, 2 in, and 2 out, both colored, and the ground if there is one is screwed to a green screw inside the timer. The 2 wires in(4) 2 colored, 1 white, 1 bare or green, should be on the "line" screws, the 2 wires out, (4) should be on the "load" screws. Are the in wires on a GFI breaker? Is the pump grounded? Are those screws in the right place? Does the pump run? Now that you are totally confused. Need to know some of this stuff.
