Taco Zone Valve Controllers
I have a customer who has 3 Taco Zone valves (2 for heating & 1 for DHW) He wants me to install a circ. on the DHW, but keep everything else the way it is. He has a Taco Zone Valve controller on his boiler. (I have never seen one before) but I dont see anywhere on the panel where you could connect a circ? Then i looked into getting a 3 zone switching realy, but then how would i connect the Taco zone valves into the zone panel? I mean I have 3 contacts on the taco zone vlaves, and how do I connect those to the zone panel? Any suggestions would be great! Thanks

I don't mean to sound like a jerk but the wire diagram is in glued to the inside of the cover. Page 31 of attached Taco Wiring Guide will give it to you also.

I have one other question about the wiring diagram that I am not understanding, and hopefully someone can help. On tthe instruction sheet for the ZVC404, I want to wire this for the optional system circ. & DHW, and if I am understanding this correctly, it's telling me to bring 120V into the Extra End Switch side, and what looks like to me being a 24V circut?

Yep!
Its just a switch. Closes the common when switched.

dry contact
It looks to be a dry set of contacts; that is, there isn't any power supplied from the board going to the contacts. As Eric said, it's just a switch, which completes the circuit, turning the circulator on.
