Default Zone valve wiring Taco

I have installed 3 taco zone valves in my 3 heating loops in my house. I need to purchase a Taco 569 transformer and need information on how to wire it. Can anyone explain this in simple terms rather than the vague diagrams on the box or the internet? I have 3 thermostats also, what wires go where? Thanks in advance! bryan

Any 120 to 24 volt transformer will work. Just get the mounting you want and if you are wiring 3 zones valves, make sure the transformer is a 40 VA or more.
How many post are on the zone valve and how are they tagged?

I probably can if you answer my question. I ask you how many post or wires are there in the zone valve? and if its wires what color are they. Your pic. did not show that. Paul

I will ask you one more time. You say there is 3 post. now those three post have to be marked so do they say 1-2-3 or a-b-c or like TH-TR, you might even have instruction that came with the valves. Do you have a two wire stat or Three wires on your stat. What runs your boiler now? You just installed the three zone valves, was there old one there before? You will have to give more info so i know what you are doing. Paul
