My CH and HW are both pumped but there is only one motorised (on CH circuit). All radiators have TRVs including the hot water tank (I think bathroom rad is also on HW circuit). Is it possible to install a room stat and cylinder stat so that when both are satisfied the boiler&pump are switched off (instead of purely relying on boiler stat)??

Yes indeed. Ay system will benefit from a cylinder and room stat.

Thanks for useful Honeywell link, will have to see if it covers my arrangement. The single MV on my CH circuit is a simple on/off (HW tees off before it) and becos of this I believe the black (or orange) wire from the MV has to be linked into HW circuit - does this wire stay live if MV closed (during a CH programmed on-period)?? At present I have TRVs so presumably MV never closes.
