Navien NCB-H 240 - Honeywell T-Stats

Member Posts: 19
I am installing a Navien NCB-H and I would like to use 2 Honeywell zone valves. Looking at the wiring diagram I don’t see “TT.”
im going to assume I can wire one yellow to normally Open and the other yellow to “common” I don’t know where to connect the red wires as I didn’t see a end switch for this. Any Information? Thanks!

You don't use the red wires, just the yellow as you wrote. Control board takes care of it0

Hello @Chris_102,
I suspect there is some language translation issues. If you use the connections in the second image, I would verify the power and functionality.
