Irritrol Rain Dial 900: Split Front/Back Yard onto Programs A and B

Programming Two Independent Schedules

1. Set switch to "SET PROGRAMS", Program A.
2. Enter run times for front zones (e.g., 1–3); set back zones (4–6) to OFF.
3. Set watering days and start time for front.
4. Switch to Program B. Set front zones OFF; enter run times for back zones (4–6).
5. Set back yard days and start time (stagger after Program A ends).
6. Return switch to RUN, dial to CURRENT TIME.

Key Point

Program switch position (A/B/C) only matters during programming. In RUN, all programs execute automatically.
