    What is your question? Do you have a wiring schematic?

    Sorry to tell you but you have the wrong mult contol for your application.

    SR relays are for multiple pumps- pump for each zone, not zone valves.

    ZVC relays are for multiple zones using one pump and zone valves.

    you would need a ZVC 403 control,

    Here is a link to the Taco site and the ZVC control.

    Ha, I didn't read it close enough I guess. Eric is right, you need a ZVC 403. There is a way to get it to work but it may be more complicated than just getting the right unit for the application. Guess I better read closer.
