Toro Vision II Controller Repeatedly Cycles and Won’t Shut Off

A 20‑year‑old Toro Vision II 9‑station controller cycles continuously. The seasonal‑adjustment slider broke, but the issue likely stems from start‑time programming.

Troubleshooting

1. Ensure only one start‑time slide switch is set to the desired time; the other two must be in the “Off” (left) position.
2. Verify no overlapping programs are active.

Given the controller’s age, replacement is advisable. The Irritrol Rain Dial series is a durable, easy‑to‑program alternative that lasts 12‑15 years.
