through the panel> You would take the common from the power supply to the zone valve motor, hot to and through the thermostat, and back to the zone valve motor. End switch of the zone valve to the t-t of the panel. Do not however use the old style heat-motor Taco zone valves with this application.

So from zone 1 hit the valve then t-stat and back to the other side of zone 1 same for zone 2? T-T sends signal to boiler to fire0 -
No, I don't think so.

You need to get 24 volt power from the panel, or from another transformer. If I remember correctly, the 24 volt power is toward the top, on the left side of the panel. Common to the zone valve uninterrupted, hot, to and through the t-stat to the zone valve. The end switch of the z-v will be used to close the connections on the panel for the circulator. Your boiler is energized through the x and x terminals.
