Hunter EC Controller Won't Update Time: Likely Failed

Hunter EC 4-station indoor controller worked last summer. Now time won't update—hours only, no minutes/days. Reset button and power cycling failed. Arrow buttons work in other menus.

Troubleshooting Attempted

Power disconnect + reset button (multiple times).
Button functionality verified elsewhere.
Display time unreliable for scheduling.

Final Steps

Gently clean circuit board with canned air and soft brush.
If no change, the real-time clock chip or microcontroller has failed.

Recommendation

Replace the controller. The EC series is outdated; modern equivalents (Hunter Pro-C, Hydrawise, Rain Bird ESP-TM2) offer Wi-Fi, better programming, and reliability.
