Programming Multiple Schedules on Irritrol RD 900 (James Hardie)

A homeowner needs to configure two distinct watering schedules on their Irritrol RD 900 (formerly James Hardie) controller: daily early morning/evening runs for stations 1-2, and Monday/Wednesday/Saturday morning runs for stations 5, 8, and 9.

Program A: Daily Dual-Cycle Schedule

• Start Time 1: 5:00 AM
• Days to Water: All ON
• Run Times: Station 1=0, Station 2=0, Stations 3-4=0, Station 5=5 min, Station 6=0, Station 7=0, Station 8=5 min, Station 9=5 min
• Start Time 2: 8:00 PM (same days and station times)

Program B: Three-Day Weekly Schedule

• Start Time: 5:00 AM
• Days to Water: Mon=ON, Tue=OFF, Wed=ON, Thu=OFF, Fri=OFF, Sat=ON, Sun=OFF
• Run Times: Station 1=3 min, Station 2=3 min, Stations 3-9=0

This two-program approach leverages the controller's multiple program capability to handle completely different schedules for different station groups. Unused stations (3-4, 6-7) remain at zero minutes in both programs.
