If he wants to do the job properly and fit zones then he can do so.
If all he wants is an override for the room stat then what I said
will work too.

But there is no evidence that that is *all* he wants.

On the contrary, why would he mention *separate* control of the
conservatory, and *zoning* and *motorised valves* if all he wanted to do was
to over-ride the room stat? He clearly had something slightly more ambitious
in mind! And, as I have said so many times that I am becoming blue in the
face, what you suggested *won't* work in a satisfactory fashion.

Meanwhile, we've almost certainly succeeded in confusing the poor sod with
all these red herrings about wiring stats in parallel. He hasn't been back,
anyway!
