3? Goes nowhere.

If you look back at the diag 3 and 2 have been swopped over for some bonkers reason which is why I used a multimeter to make sense of it all.
Basically power goes from 1 to the bimetallic stat. When it closes,i.e. calls for power it connects to the load connection which then makes the relay back at the consumer unit close so power goes to the under floor heating element. Once the temp rises to the point at which the stat opens power to the relay is cut off and the element gets no more power until the reverse happens.
So it works. It is either closed or open, and in the open position the power goes nowhere.

Ah you see information is king :).

So all it’s doing is switching a relay somewhere else that takes the load for the floor element.

Why I didn’t think of that when you said you were gonna connect the load across a bimetallic switch :vb-groan2:.

There are 5 zones at 10 amps and one the lounge-diner the biggest room at 20 amps if you look at the consumer unit. But these are then subdivided, for example, the guest wing has 3 zones, 2 bedrooms and the night hall and the bathroom.

I used the term "load"as that is what the frogs call it. But it sure as heck ain't the full load!!
 
Friday the defender failed the mot due to the break fluid having to much moisture in it over here thay insert a probe in the reservoir for a reading, I should've known better ! But all sorted now so back tomorrow, also cleaned all the sensors what a difference it has made . Good night was had at are village food and drinks and dancing to the excellent band all home produces the prosciutto was marvellous and I piged out on it ☺

I would also add that the switch makes the connection (would agree bimetalic switch) to P & N but the load, your floor element maybe off terminals 5&6.

Who knows what goes on behind?

5 and 6 are supposed to light a lickle LED light or summat, which is there but don't work as far as I can tell. But I don't need it. ;)
 
How can anyone be so stupid.
It's people who are in their own little bubble and only think of themselves, their immediate needs and no-one/no-thing else.
My NDNEEBS spring to mind.
Out in the front garden chop-sawing wood for a new floor, plumes of sawdust up in the air and...all over our cars and our front garden.
