SOURCE: 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

SOURCE: how to connect an omron h3y timer into a circuit

I see your comment to ignore:
To protect timer, read following:

1) Max load on this timer is 5 amp at 240volts
http://waterheatertimer.org/pdf/Omron-H3YN0302.pdf

2) If load exceeds 5 amps, then use timer to control contactor.
Here is crude drawing showing basic wiring for pin timer controlling heavy amp load.
http://waterheatertimer.org/images/10-pin-wiring2-1000.jpg

3) If amp rating on incoming wires exceeds 5 amp, for example is circuit breaker feeding circuit is 20-30 amps etc, then protect wires to timer using busman in-line fuseholder with fast-acting 5 amp cartridge fuse.

I need to run a contactor ( 40 amps 3 phase ) with the help of thermostat..i have connected L1,L2 n L3 and output coneccted in T 1 T2 T3 . now how to connect A1 and A2 .... i want that contactor should...


1) Copy following links for illustrations showing timer controlling contactor in 3-phase environment:
http://waterheatertimer.org/How-to-install-3-phase-timer.html
http://waterheatertimer.org/images/3-phase-timer-diagram-24Vac-865.jpg

2) Substitute thermostat instead of timer for switching control.

3) I don't know what thermostat you have, or if it's functioning or the rating.

4) Which contactor do you have?
Do you have a 3-phase contactor??
Or two-pole single phase contactor?

5) Match thermostat output voltage with contactor voltage:
Thermostat output is 24 volt? Then use 24Volt coil on contactor.
Thermostat output 120 or 277 > then use contactor with same coil rating.

6) More information is needed.
I don't understand description of your wiring.
Add a comment and compare with illustrations sent, so I can visualize ... or attach photo and/or give product numbers so maybe I can locate wiring diagrams.

How do I connect my Jandy AE-TI heat pump to my intermatic T104P3


1) Copy following link for wiring illustration ... assuming timer is supposed to control pool pump:
http://waterheatertimer.org/images/T104-to-contactor.jpg

2) T104P is 240Volt (208-277V) SPDT timer in P plastic outdoor enclosure.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T104

3) Jandy AE-TI is 208/230V pool heater.
http://www.bestbuypoolsupply.com/media/aemanual.pdf

4) Page 13 of Jandy manual shows single-phase residential wiring diagram.

5) First of all, power to main contactor is not interruped by timer, since this powers 24Volt transformer that controls the chip board and general operation.

6) The timer is connected to 'Auto-heat contactor.'
The confusion is what Load connects to this contactor? The water pump? Load is shown on diagram as 'pump time clock.'
I assume the load is the PUMP??

How do I program the H5CX ASN timer to turn on 5 mins and off 25 mins in an endless cycle. I don't understand the term Output Mode so from that point the instructions become meaningless.


Omron:
https://www.ia.omron.com/support/
http://waterheatertimer.org/pdf/h5cx_sell-sheet-wiring.pdf

I believe you have 230Volt 50 Hz electric power.
Omron is rated 50-60 hz
US timers are rated 60 Hz.
Maximum load on Omron timer is 5amp at 230 volt
Timer should be connected to 2-pole contactor (relay) instead of directly connected to pump.

Does Amazon sell percentage cycle timer in your country?
A cycle timer makes one full revolution each hour, or 4-hours, or 12 hours. Then percentage is set for 8% for 1 hour cycle.
Contact Intermatic and ask if they have 50 cycle percentage cycle timer, or ordinary cycle timer in 50 Hz.

You want 3 minute 'off delay' timer.
When timer is energized with push button or momentary electrical signal, circuit remains ON for set amount of time, and then turns OFF.
http://waterheatertimer.org/How-to-wire-Dayton-Off-Delay-Timer.html
Aug 15, 2011 Dayton/ Grainger website is offline

Most delay timers have 1 amp capacity rating, so circuit needs fast acting 1 amp fuse, and timer controls separate relay or contactor unless Load is equal to 100 watt light bulb.

I am a Home Inspector. How do I override the timer controls to produce heat at the ETS units so my clients can see that they work. I put the timer lever in the manual position however after 30 minutes no...


You posted under ET70415CR. This is a complicated timer with many wiring and programming capabilities.
Open following links for ET70000 series image and ET70414CR instructions:
http://waterheatertimer.org/images/ET70115C-copy.jpg
http://waterheatertimer.org/pdf/Intermatic-et70415cr.pdf

Among the features, this timer can be programmed for pulse or momentary action to control external latching contactors:
Page 36 of instruction says:
Note: Using the manual On/Off keys to switch this type of contactor On or Off may not provide the expected result and may cause damage to the contactor coil. For this application external Momentary Pushbutton may be added for both circuits or the circuits may be programmed for override pulses.
So instruction is saying that additional wiring is needed to override specific types of circuits.

The timer has 8 internal contactors, and each can be controlled separately by the timer to control 8 different electric circuits. This is called 8-channel timer since all eight timing contactors can be programmed separately.
Each contactor is wired separately to control any type of electrical appliance including 440V lights, and 24V alarm system, and 240V heat, etc.
For example contactor1 might be for lights, and contactor2 for controlling a latching contactor, and contactor3 for controlling a boiler, contactor4 etc...

To override the system, you have to identify which contactor controls the system in question.
Then there are 2 options:
1) Reprogram the timer on that channel
2) change the wiring temporarily: Each of the 8 contactors has 3 screw terminals: COM, NO, NC. If there are wires on all 3 NO NC COM terminals, you have to reprogram timer. If there is a wire on NC terminal -or- NO terminal, typically you would move that wire to the COM terminal to by-pass timing operations.
