Honeywell Zone Valve

Is the V8043F series compatible to a ZVC406 Taco zone-valve controller?

I would just like to simplify wiring with a singular control board instead of daisy-chaining all of the end-switches to the pump relays R-W terminals. The secondary loop was re-piped with a differential bypass to bleed off the extra flow as zone-valves open and close.

To simplify my question, can I use this zone valve in a 2-wire application?

Thinking about it and trying to answer my own question, it seems that I should be able to use terminals 1 & 2 of the Taco ZVC to wire in the TH and TR terminals to power open and close, jumper 3&4 on the ZVC controller for end-switch, and run my T-stat leads to the R&W of the ZVC. (?)

I met you in Denver at Wetstock III and appreciate your books. You have helped me get leap years ahead of where I was. Thanks in advance.

    since nobody replied.

    I could not read the details on your Taco controller, but if it's anything like some of the Taco controllers I have seen, I dont see a problem. 2 wire zones are the easiest to adapt to other applications, 3 wire needs alittle thought and planning but I think you should be OK.

    This zone valve is definitely compatible with the Taco controller you selected.We distribute both and match them all the time
