The only difference between a zone for each room and using TRVs is how
accurate the temperature sensor is in each case.

A zone stat will include a switch to signal demand, a TRV doesn't.

You site the main house stat in the area of most demand.

(Yes, you can get programmable TRVs with radio switching - that's
just sticking the zone state in the valve head.)

I can see zoning being useful in commercial premises but not really worth
the bother in the average house. Unless it's set up to alter temperatures
in each area automatically. And you have door closers everywhere.
