I need a replacement for a 120VAC, 24 hour, Paragon model 4004-20S timer with two sets of NO-NC contacts. Timer operates when clutch is de-energized.

Timer brand and model number are not shown.
Brand and model appear on inside of timer door.

Moving stationary pointer will not affect on-off operation of timer. The pointer is just reference for setting current time.
Worn trippers can cause problem.
Trippers are softer metal and designed to wear down so timer mechanism lasts for decades.

Intermatic pool timers use set of 156T1978A trippers.

Tork timers use P47 tripper on 24-hour clock dial
http://www.frontierlighting.com/find.jsp?a=1&ID=,Photo.Cells...Time.Controls,Replacement.Trippers
Paragon 4000 series uses X2772 tripper. Paragon timers are discontinued and trippers hard to find.

Open following links for different timers:

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.

You posted under Paragon 1015 timer.
Open following link to identify timer and download manual.

Timers are 24 hour, but some have 7-day capability:
Manual says: to set 7-day grasp large 24 hour dial and rotate either direction until correct day of the week appears below Day Set red dot and 12 noon on large 24 hour dial is below red pointer.
To set 24 hour, grasp large 24 hour dial and rotate either direction until correct time appears below red pointer.
Red pointer is stationary at 6:00 position.

I cannot find a brochure showing specific paragon tripper numbers.

You have Paragon 42013-20 timer, DPST 10Amp 2Hp, Nema3 indoor-outdoor, 24 hour-timer with 48 trippers built into timer dial.
http://waterheatertimer.org/Paragon-timers-and-manuals.html#42000
If trippers are worn out, you can possibly work-around by rotating dial 12 hours so fresh trippers can be accessed using same dial. The only difference is nighttime hours shown on clock face will now represent daytime hours.

Difference between your paragon timer and suggested intermatic, it that Paragon throws both terminals at same time, while Intermatic has alternating NO NC terminals.

http://waterheatertimer.org/Paragon-timers-and-manuals.html#defrost

According to e-mail I got from Paragon in Nov 2010, Paragon is no longer making timers and parts.
Except for defrost timers.

I don't know how narrow the Paragon defrost line has become, if they still making their commercial refrigeration timers, or if they're just making smaller refrigerator defrost timers.
Or if Paragon has parts for the 8025
http://www.uni-line.com/common/custserv.aspx

1) Paragon is no longer making timers and parts except defrost timers.
4004-71M is not defrost timer.

2) Manual shows 4004-71M is DPST 40 amp 240Volt timer.
4000 series is 24 hour repeat timer

3) To buy replacement timer, Intermatic crossover guide shows T104M used for pool and spa controls and to replace timer mechanism

T104M at amazon
http://www.amazon.com/Intermatic-T104M-Mechanical-Mechanism-208-277/dp/B001DNYMV6

4) Or you can buy T104 with Nema1 indoor box, or T104R with Nema3R outdoor box
Googel search model number for vendor

Paragon 4001 is 120Volt SPST indoor timer.

I've never seen knock-outs for these timers on top because the timing mechanism is in the way.

Turn timer sideways, the timing mechanism still works.


Timer flipped 90 degrees so KO is on top

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.
