Understanding Multiple Programs on a Rain Bird Controller

Program A vs. Program B Zone Times

The user is confused why zones have different run times on Program A versus Program B on a Rain Bird controller.

How Multiple Programs Work

Most controllers allow multiple independent programs (A, B, C). Each program can have its own start times, days, and zone run times. Zones always run in numerical order within a program; you cannot reorder them (e.g., zone 5 before zone 8).

Consolidating to One Program

If multiple programs are unwanted, go to Program B, set all zone times to zero, then enter the desired times in Program A. All zones will run sequentially in a single program.
