Fixing Multiple Start Times on a Hunter EC Irrigation Controller

If your Hunter EC controller is watering the same zones repeatedly in a single cycle, the issue is likely too many programmed start times. Each program only needs one start time to run all assigned zones sequentially. Here's how to clear extra start times and restore proper operation.

Understanding Start Times

A start time initiates the entire program — all zones with run times in that program will run in order. Adding multiple start times causes the program to repeat, leading to overwatering.

Step-by-Step: Removing Extra Start Times

1. Turn the dial to Set Watering Start Times.
2. Use the + or - buttons to navigate to the unwanted start time.
3. Press the - button until the display reads 12:00 AM, then press - once more to reach OFF.
4. Repeat for any additional unwanted start times.
5. Ensure only one start time remains active per program.

Verify Zone Coverage

Confirm that all desired zones have run times assigned in the active program. Zones without run times will be skipped, even if the program runs.

Pro Tip

After editing, run a manual test cycle to verify the sequence completes correctly without repetition.
