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.

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.

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:

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.

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

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.

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.

3-minute off delay pin timer
Omron shows 120Volt 8-pin M-series-(minute) 3 minute delay timer
Part number H3CR-H8L 120volt M

I don't have exact schematic for your 8-pin timer.
Use multimeter read ohms and voltage from pin socket to pin socket.
Use multimeter set to ohms to read continuity of pins on timer.
Pin timer relays have NO NC pins.
Some pins are Normally Open (no current flows until timer turns on)
The other pins are Normally Closed (current flows until timer turns on, and when timer turns on, this circuit turns off)
