Rain Bird RC Series Pump Start Wiring: Use Master Valve Output

To connect pump start relay to Rain Bird RC series:

1. One pump start lead → controller Master Valve lead (White/Orange).
2. Other pump start lead → controller Common (White) with valve commons.
3. Tape unused Master Valve lead if not used.

This sends 24 VAC to pump starter when any zone runs. Verify 24 VAC at pump starter coil.
