Hunter Controller Zone Running Too Long: Programming Error or Hardware Failure?

Zone 6 Runs Over an Hour Despite 10‑Minute Setting

A Hunter controller that drastically exceeds the programmed run time for a single zone usually has an extra start time hidden in another program (B or C).

Check All Programs

1. Review Programs A, B, C for any run time entered on zone 6.
2. Zero out all run times for zone 6 in Programs B and C.
3. Ensure only one start time exists in Program A (or whichever program you use).

If the problem persists after cleaning all programs, the controller’s microprocessor is failing and the unit should be replaced.
