I have a Laars mascot 2, 2 zones with taco 570 zone valves, 1 taco 007 circulator and a taco sr502 relay. Need help with the wiring please.



Thanks,



Pete

    Question

    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.
