Looking for a smarter way to manage your heating this winter? We’ve been testing the new Aqara Radiator Thermostat W600 to see how quiet, accurate and easy it is to use around the home. Click here read our review.

That will depend on what’s on the other ends of those wires. I guess you have a bell transformer somewhere? And a button? I guess that the 4-core wire with the blue/green/white striped cores goes to the button - check inside the button to confirm.
Thanks for the quick response mate,yip still trying to find out where the old bell transformer is as someone had installed a new bell but wasn't working Wonder why I do have a doorbell attached to door frame outside but never has worked

Isn't what you've written a little confusing? Surely 1 & 2 go to the bell push whether or not batteries are fitted (and also to the transformer/power supply if there are no batteries and power is coming from a transformer) - not just "when batteries are fitted"?

If bell push to 1 and 2 the transformer would need to go 0F to 1, and a link 2 to T3.
With a transformer, the voltage is 8 volts AC, and with batteries voltage 6 volts DC, the coil has a higher impedance with AC to its resistance with DC, so higher voltage, there is no way you can have a transformer and batteries, it is either/or not both.
I would say your description is very confusing, I read it "also to the transformer" that would be a direct short when the bell push is pressed. Also, massive difference between DC power supply and a transformer, the DC power supply would need a very high current and would need to be massive, and also a lower voltage, to AC. We see a transformer rated at around 8 VA, but when bell push is pushed it uses well over that current, around an amp, (16 VA) but for such a short time it does no harm to a basic transformer, a power supply with diodes in it however would be different. It could very well be damaged.

Yes, I was for from clear enough.
Agreed - as above, although my brain knew what I wanted to say, my typing fingers made a mess of it. Apologies.

I am the same, I blame dyslexic problems, I know what I want to say, but it does not read the way I intended. That's the whole thing with a forum, someone proofreads what one has said.
Seems I made an error also, it is 8 volt AC. Thanks to @opps for finding the instruction set.
Well spotted. I'll bet they were the L and N, which originally fed a transformer, wich then fed a bell. Since when, the transformer, and bell, has been replaced, with a newer chime, which used battery.
Bet, if the OP fitted a set of batteries, and reconnected those wires, to terminals 1 and 2, the chime would work.
Yes, it will have been a doorbell with a built-in transformer once upon a time.
Seem to recall they were all the rage in the early 2000s.

My thinking with the “do you have a multimeter?” question was to follow up with “what do you measure on the wagos, 8 V AC, 240 V AC, or nothing?”.
