Whiye Rodgers Zone valve's. Thank you!

Hey everyone,
Thank you for all the input that I recieved on this subject. I wasn't sure how to address this one piticular thread so I figured I would just post a new message. I had the polarity back wards on terminals #1 & #2. I didn't think they were polarity senesative. I went back and switched the #2 from common to hot, and made #1 Common. In the schematic that comes with the zone valves. It does not really show you which is hot and which is common. Yet on another schematic I found that it showed which was which. Now some of you may be saying No way it couldn't be. I wired many that way and never had a problem. If that is the case then I had a loose wire because it is working. I did so many different things I can't remember everything I did. I'm sure you have had a time like that once or twice. Anyway I really appreciate all the input and I learned alot.
Thank you all.

That is because you

must have a control center on a Weil-McLain CGa boiler. That requires a special wiring hookup. If you e-mail me I will send you the diagram.

Normal wiring is the Hot "R" terminal goes to #1 and the "C" common goes to # 2. With the CGa it is different.
