Rain Bird System Requires Manual Pump Switch – Relay or Wiring Fault

User must flip pump switch manually each cycle. Gravity flow creates puddles.

Checks

• Controller has wire on PS (pump start) or MV terminal?
• Controller outputting 22–26 VAC on that terminal when zone runs?
• Relay at pump working? Wire intact?
• Controller programmed for master valve/pump start?

Relay, wiring, or controller programming issue.
