taco zvz404 to circulator?
The Taco has been working flawlessly since Nov. on a three zone system we put in as a temporary fix for 3 sunken boilers in my apartment building. Was messing with the boiler his weekend to rig a male plug into the boiler wiring so I could run it off a generator or battery. Works fine either way.
Only thing I noticed: The circulator continues to run after the thermostats has been satisfied and all zones valves are closed. I checked the wiring diagram and it appears that the zone valve control should be wired directly to the circulator via the pump end switch. I swear it wasn't runing like this at the time of install and that I read in the manual that we didn't need to hook up the circulator when the electrician and I were trying to figure out the wiring. But we were both pretty tired post Sandy so who knows?
Time for adult supervision or should I just switch the circulator wires from the New Yorker's control board to the Taco? Looks pretty straightforward, but I'm not sure what that's going to do to the Honeywell relay it is plugged into.
Thanks in advance.
