Linking zone Valves/Circuits - Nest Thermostats

[ruytf]

Don't ask me why I want to do this as it is a long story best left for a pint or two... ; ) but I have three Nests thermos, each has its own zone valve/circuit. (Temporarly) I want to to control all three zones valves/circuits with just one of these Nests thermos - whats the wiring way to achieve this? Ta

The other zones would have to be linked to the one Nest you want to use as as single controller. Probably best done in the wiring center.

Well, more information is needed then. What type of system is it? Are the 3 zones just heating zones? Is there an existing wiring center? If yes, post a photo of it.
