I'm installing a wiring center for UFH. I understand the wiring diagram but I only have a 2 port valve for the UFH manifold. It says to use zone4 for rads and wire L N to a vavle which can then wire to Ls and Lr on the boiler enable. Only problem is there is no valve, can i use L N to call for heat from the boiler somehow without a valve as it seems unnecessary on a combi system.

You need another zone valve as your drawing shows.
