Wiring zone valve in Crown Boiler AWR series

Hello everyone. I purchased a new gas boiler(Crown AWR series) and replaced my old one recently. I am very happy with its efficiency. However, I need help finding a solution to wiring it to my old zone valve. I only have one circulator and 3 zone valves which are Honeywell v8043s. Now I open all zones manually and use one thermostat temporarily. But I want to wire it to 3 zone valves and three thermostats. Thank you.

    Get a Taco ZVC4 zone control panel and follow the wiring instructions.

    You can choose to do what you want, but you cannot choose the consequences.

    The instructions that come with the Honeywell zone valves (also available on line) is easy to follow, OR you could get a Zone Valve control panel like the Taco ZVC-403 (or ZVC-404 if you plan to add a zone in the future) to make for easy trouble shooting in the future.

    After you make that expensive repair and you still have the same problem, What will you check next?
