Need more info (If you know the exact components, that would be very helpful):

1. Is each zone separately timed?

2. If yes, separate timer or programmable stat?

3. Which boiler (make and exact model)?

If the boiler uses pump overrun, then the pump will be wired directly to the boiler. So you will need an Automatic Bypass Valve fitted after the pump and before the zone valves.
