Understanding Program Display on Toro Gatekeeper 212 Controller

A user with an older Toro Gatekeeper 212 controller cannot get "Program A, B, or C" to display when the switch is set to Run, despite all settings being configured. The system runs manually but not automatically.

How the Display Works

When the switch is in the Run position, the controller executes all programmed schedules simultaneously—it does not display individual program letters (A, B, C). Those letters only appear during the programming phase for each specific program. Ensure all desired functions (start times, run days, station durations) are set within each program you intend to use.

Troubleshooting Automatic Operation

If programming is correct but the system still won't run automatically with the switch in Run, the controller may be faulty and require replacement. Verify that the Auto/Off setting isn't disabling automatic cycles.
