Irritrol RD-600 Runs Daily Despite M/W/F Programming: Check Programs B & C, Battery Not the Issue

Program A Set for M/W/F, But Runs Every Day

First, check Programs B and C — if they have days set (e.g., Sat, Sun, Tue, Thu), they'll run on those days. Clear B and C.

Battery only holds memory during power outage. No battery → defaults to 10 min daily at 7 AM after power loss. Install battery to prevent this.

Controller panel may need repair or replacement. Remove panel (pull ribbon, snap hinges), take to irrigation store or Irritrol (1-800-634-8873).
