Wiring a newly installed boiler

I am installing a new york boiler with 1 pump and 2 zone valves and a taco control, do I just conect 120 to the boiler and another 120 to the taco box? Then the pump and valves to the taco box? Doesthe taco boxmake the wiring that simple?

    Something like that. I'm assuming your talking about a taco zone relay like an SR501? You most likely didn't need it but that depends on the aquastat you're using.

    Make sure you come from the service switch on the boiler to the zone relay you need to be able to shut off the relay and pump to work on the system. Some of the SR500's have a built in 24v transformer that you need to supply the zone valves with. Then just wire the end switch on the panel in parallel to the zone valves and into the aquastat.

    If your aquastat has a circulator control (C1, C2), and most do, you don't need a zone relay at all, Just a 24v transformer.

    All on the same 120V circuit

    Slightly off topic; how would you wire/power a zone valve using the transformer in an SR501, along with the thermostat?

    You wouldn't, you'd use a ZVC, or zone valve control

    Agreed, but say you already had a 501 unit for another application and wanted to add on?
