I had a timer installed today for my 2 pool lights. They come on only if I manually flick the switch or rotate the timer.

The timer does not seem to rotate. It was sitting at 18:30 for 2-3hrs today.

Could it be wired wrong?

Pls See attached picture

No neutral for the clock to work??

????

1) Pool lights -> I assume you want to switch on/off the transformer for the pool lights (submerged) or where do the red and blue wire go to?

This timer switch is meant to switch 230V AC.

2) Two wires, how could this work?

It has four terminals:

Power S1 and S2

Load L1 and L2

My idea:

AC phase to S1

AC neutral to S2

L1 to transformer terminal (1)

L2 to transformer terminal (2)

But wait for the real experts

AND before I kill you: if the blue/red wires are directly going to the lights NEVER contact AC to that thing!!!!!!

Yes it's mean to switch the pool light transformers on/off. There was a simple switch there before.

The pool guy brought in his electrician to hook it up, guess i will ask for another electrician to check it out and hope he knows more. Thanks for the tips.

KhunBENQ has it right.

So I assume (and you should test with a phasing tester!):

The red wire is AC phase (hot wire, always on).

The blue wire goes to one of the transformer terminals.

The other transformer terminal is fixed to neutral.

So the thing could work if you connect S2 to AC neutral as asked about in post #2.

Means you have to supply a third wire from AC neutral to the switch.

Would be a working three wire solution.

But as written: no chance with two wires.

The assumption could go wrong, if that "electrician" instead switched AC neutral

I'm really no expert, glad for the tips here. I will find out if the electrician coming next week comes from the trade.

He is coming to install a t-cut for the house, we already have a t-cut for all lower level (gardens, pool etc.).

These timers need constant power applied so the clock works. That means at least 3 wires needed - active+neutral supply to power it, and switched active out.

Refer your electrician to the schematics.

I got ot it hooked up now through a proper electrician and we didn't get electrocuted after our evening swim.
