Here are two possible solutions, since timers are made different ways:

1) Diehl timer has 5 terminals
Drawing below shows wiring for Diehl SPST:
need wiring diagram SPST  power to timer  timer to - geno_3245_259.jpg

2) Your timer might also be wired as follows:
Two screws marked 'timer' are for 120Volt Hot and Neutral that power the clock motor (in drawing above, these are terminals 1 and 2).
Another Hot wire connects to COM. (in drawing above this hot wire shown connecting to terminal 3)
Load wire connects to terminal NO (in drawing above this wire shown connecting to terminal 4)

3) NO is Normally-Open turns ON when tier turns ON
NC is Normally-closed is ON all the time, EXCEPT when timer turns ON. So NC terminal turns OFF when timer turns ON.

I need a wiring diagram for an Omron H5CX-A timer


Wiring will appear on side of timer.
Test the timer with multimeter to see which terminals are connected. When timer has no power, then Com and NC terminals will have continuity.
H5CX-A Timer has 11 screw terminal connections and timer is rated 100V to 250Volt AC 50-60Hz.
Input is power IN > this is the 100V to 250Volts coming from breaker box or transformer. For example input terminals might be labeled A and B.
This will give power to timer, but remainder of screw terminals have no power.
To put power to relay terminals, jumper the power from Input terminal A to COM terminal.
For example Com terminals might be 7 and 9.
So jumper Hot wire from Terminal A to terminal 7.
This action will put hot on Com terminal 7, but also give power to the NC terminal.
For example the NC terminals might be 1 and 3.
So when timer is OFF, the NC terminal has power.
Then when timer turns ON, the NC terminal no longer has power, but the NO terminals are Hot.
NO terminals might be 4 and 6, and these terminals turn on-and-off when timer turns on--and-off

HOW I INSTAL ,CONNECT SWITCH TIMER TE502 ? IT


Wiring diagram shows on side of timer and looks same as to following illustration:
http://waterheatertimer.org/images/NO-NC-timer-200.jpg
For more complicated illustration showing din rail and modular timer wiring variations:
http://waterheatertimer.org/images/NO-NC-timer.jpg

With din rail timers, the power connects to screw terminals 1 and 2 and this will run the clock and relay.
The TE502 image is bad, and I can't see wiring diagram exactly.
It appears that terminal 4 is common. This is typical for din rail timers.
Put Hot lead to terminal 4.
Terminal 3 appears to be the NO terminal, so put wire going to Load to terminal 3.

How i can do the instalation


1) Need more information.
Heres some help to get you started, then you add a comment and fill in details so I can give accurate answer.

2) You posted under Paragon 7008-00 timer.

3) People post under Paragon when they have Tork, so I need exact model number and what voltage you have and what Load you are trying to wire.

4) Also what terminals appear on timer, since any timer can be in a box that is marked 7008.
Then add what color wires you have coming from breaker box, what size breaker, and if same breaker is going to supply voltage to timer and to Load, and what color wires are going to Load.

5) Open following link to identify timer for sure, and see manual and wiring diagrams.
http://waterheatertimer.org/Paragon-timers-and-manuals.html#7000

6) Typical wiring diagram for 7008 showing one set of NO NC terminals:
http://waterheatertimer.org/images/Paragon-7008-00-timer-wiring-350.jpg

7) 7008 timer has 120Volt clock motor. So power to terminals A and B has to be 120V.
But timer can still control 120V or 240V loads.

8) According to manual, 7008 timer has 2 NO (normally open) terminals that are OFF when timer is OFF
Timer also has 2 NC (normally closed) terminals that are ON when timer is OFF

9) Both sets of terminals reverse when timer turns ON.

10) NO and NC terminals are frequently used for continuous-operation 2-speed motors, for example.
You do not want power to both speeds at same time, or motor will burn out. So low speed is connected to NO terminal, and high speed is connected to NC terminal. This way the motors windings are kept separate, and either low speed is ON or high speed is ON.

11) Another example of NO NC terminals could be store lighting. When store closes, the timer turns off exit signs and store-room lights inside store, and at same moment timer turns on burglar alarm and outdoor lights. In this example the timer controlled 4 different circuits: exit signs, store-room, alarm, and outdoor lights. With 2-NO and 2-NC terminals, that is possible.

How do I connect my 2 speed pool motor?


1) You might need a different timer.
240Volt T106 has one NO terminal and one NC terminal.
http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/t106r%20-%20english.ashx

2) Terminal 1 is NC terminal
NC terminal is 'normally closed' so electricity flows continually through this terminal.
For example you can connect this terminal to speed-1.
So speed-1 is on until timer turns on, and then electricity is turned off to NC terminal and speed-1 stops.

3) Terminal 4 is NO terminal
NO terminal is 'normally open' so electricity flows through this terminal only when timer turns on.
For example you can connect this terminal to speed-2.
So NO terminal only has power when timer turns on.
When timer turns off, NO terminal turns off and NC terminal turns on again.

4) As you can see, the problem with T106 timer is that pool motor is continually running.
Either speed-1 is on, or speed-2 is on.

5) Here's how to wire T106 for 240V two-speed pump:
Two hot wires arrive from breaker box: 1 black wire and 1 white wire.
White connects to terminal A
Black connects to terminal 3.
Three wires go to motor.
Speed-1 connects to terminal 1 probably black wire
Speed-2 connects to terminal 2 probably red wire
Remaining motor wire connects to terminal A probably white wire
Ground wires connect to green ground screw.

6) Usually, 2-speed pool pumps are wired to dual timer like T10404R
So each speed is wired to a separate timer.
With this timer, each speed is connected to separate timer, and then the pump can be turned off when neither speed is needed.
http://www.amazon.com/Intermatic-2-Speed-Timer-208-277-T10404R/dp/B002UBPCDW/ref=pd_sim_sbs_hi_1

7) However there is a newer electronic timer P1353ME and P1353ME-6 and PE153 that can control 3 different loads. This timer snaps into any T106 box.
For example speed-1 is one load, speed-2 is another load, and a pool light can be third load, or simply do not use third load.
http://www.amazon.com/Intermatic-P1353ME-3-Circuit-Digital-Switch/dp/B001DSEC7A

http://1000bulbs.com/product/3352/ELEC-PE153.html

8) I am familiar with wiring and programming for P1353 timer, and you can post again on fixya, and I will catch the question.

Add a comment for more free help.
Also take advantage of fixya phone service.
For a price, expert speaks with you over phone while you work on timer or any do-it-yourself project.

Can I used the T103M dpst spst timer for christmas lights? I would be coming off 2 20amps breakers in a single slot. I relly don't understand what a dpst and spst are (what they do) I am trying to hook up...


T103M is 120Volt timer that can handle all the Christmas lights.
Minimum on-off time 1 hour.
Rotate dial until current time lines up with silver pointer.
Set on-off trippers on dial.
Let's go step by step.

1) T103 has terminals A 1 2 3 4 >> terminals are also called poles
DPST (double pole single throw) and SPST (single pole single throw) are two different ways to wire this particular timer.
T103 timer can be wired numerous ways... but your project is not complicated.
DPST means timer turns off two terminals/poles (double pole) with each click/throw of timer switch (single throw)
SPST means timer turns off one terminal/pole (single pole) with each click/throw of timer switch (single throw)

2) T103 timer is ST single throw, all the lights come on at same time. So this timer is 1 channel.
1 channel timers are either ON or OFF and everything turns on-off at same time.
You cannot stagger on-off times with 1 channel timer.
If you want upstairs and downstairs lights to come ON at different times, you need two timers .. or a 2-channel timer (which is different ballgame).

3) T103 timer has 120Volt clock motor that is connected to terminals A and 1.
Look at timer and you can see small white wires connected to A and 1 terminals that power 125V clock motor.
When wiring this timer, your wires from 20 amp breaker box connect to terminals A and 1.
Black hot wire from breaker must connect to terminal 1
White neutral wire from neutral busbar must connect to terminal A
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T103
http://waterheatertimer.org/B220C.html

4) Terminal 1 must be hot so when timer switch clicks ON, it sends power to terminal 2.
Your load wires connect to terminals A and 2
I made simple drawing of SPST option showing how to wire T103 to 3 receptacles.
Fixya downgrades image so it's hard to see.
Hot wire to terminal 1
Load wire to terminal 2
Neutrals on terminal A
To see image larger:
http://waterheatertimer.org/images/110-600-21Kb.jpg

geno_3245_171.jpg
If you want to wire timer for DPST, which is necessary for loads exceeding 2 horsepower (1500 Watts) on each terminal
Notice black jumper wire from terminal 1 to terminal 3
Notice all white neutral wires to terminal A
To see image larger:
http://waterheatertimer.org/images/110-600-17Kb.jpg
geno_3245_172.jpg
I made third image for guy who was wiring high amperage blowers, that show wiring for two T103 timers. Having two timers would let upstairs and downstairs lights come on at different times.

I have a 110 Pool Pump and I am trying to wire it into a Tork1103NC timer. From the pool pump I have a black, white and green wire that I need to wire into the timer. Can you tell me what position those...


0fde0d6.jpg

Here is Tork 1103 wired for single load.

1) The green pump wire and bare copper wire go to green ground screw
2) Pump black wire goes to pole 2, the NO (normally open) pole
3) Pump white wire goes to unmarked screw

4) Black from circuit breaker goes to pole L
The T1103 comes with a removable brass bar that connects pole L and pole 1
If that removable brass bar is not there, then add a jumper between pole L and pole 1 as shown in diagram above
5) White neutral from breaker box goes to unmarked pole (all whites connect to unmarked pole)

In your case, pole X is not used. Pole X is NC or normally closed > which means the power is ON continuously until timer turns on, and when timer turns ON, the NC pole turns OFF

Instruction sheet
Sales sheet

Deihl spa-and-pool timer shows a 15A DPST NC NO timer in sales sheet
Wiring diagrams show DPST.
However most 880's sold are 125V SPST.
Deihl makes 125 V, 24V and 240V models ... but I don't have product sheet that shows all models

I don't see any NO NC wall-timers while looking at: Woods, GE, Intermatic, Aube, Hagar, Leviton, Lutron, Paragon, Pass and Seymour, Swilight, Sylvania, Timex, Tork, UPM, Utilitec

Box timers by Intermatic offer NO NC:
T1900 series
T171

Ordinary 3-way switch is NC NO
Ordinary 4-way switch is NC NO can be wired to control 2 independent circuits

There are heavy load NO NC contactors (relays)
Item 2cg37
You can wire ordinary wall timer to control the contactor

HAVING TROUBLE INSTALLING A GE DIGITAL TIMER SWITCH HAVE A HOT WIRE LOAD WIRE AND NEUTRAL I CONNECT HOW THE DIAGRAM SHOWS AND GET POWER TO THE UNIT BUT WHEN IT IS SWITCHED THERE IS NO POWER TO THE LIGHTS....


OK NC== Normally CLOSED.
NO==Normally OPEN.
COM=Common.
SO IF you use the NO, the thing will BE OFF, at the start.
If you use the NC, the thing will BE ON, at the start.
The COM. Is the the common connection to all.
