Anyone familiar with multi zoned two pipe gas hot water systems?

I have several Navien CH240 installed in several apartments in a New Haven building. I now want to convert to a two pipe -- one pipe to feed all the radiators and another to bring back the return water -- system that extends around the entire periphery of this one floor apartment with 3 bedrooms and a large living room.



Would like to create multiple zone valves using Taco, Danfoss or other zone valves.



Need advice on the system design, whether or not to go with wireless, and how are the zone valves to be wired. Does the Navien CH 240 have any facilities to make this approach appropriate??

    Have you looked at page 19 of the I&O manual? It shows you how to do it. There is one misprint: at the bottom of the zone panel, it shows circulators. They should be zone valves instead.
