    You boiler connection should be to the “isolated end switch” terminals next to the thermostat terminals, not the pump end switch terminals.

    Also, make sure that your zone valve wires are in the proper order.

    IDK. You haven’t shown what valves you have or how they’re wired.

    If they’re Taco 3wire valves, then follow the diagram. If they’re something different, then post some pics.
