In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I have a question regarding wiring a ZVC to a boiler that has built in DHW Priority (Triangle Tube Prestige Solo 175).
I have a ZVC 406-4 and am planning on using this in NON priority mode to be able to power up to 6 zones (4 currently in use). I would like to use the boiler's built in DHW priority switching so that I don't have to use one of the ZVC zones for DHW. In this case, how would the system circulator be wired?
The Taco instructions indicate the circulator should be wired directly to the ZVC, but it seems like this could end up ignoring the boiler's DHW priority control. Instead, I feel like I should only wire the temp relay from the ZVC to the boiler and then run the circulator from the boiler's circulator outputs. Is this correct? In that case, do I still jumper the 120v to the dry contacts on the ZVC or leave those contacts empty, only powering the relays?
Thanks a TON.
