Hunter EC Controller Stations 1&2 Not Working: Power Surge Damage

Hunter EC Controller Loses First Two Stations After Power Failures

A Hunter EC 6-station indoor controller skips stations 1 and 2 in auto mode, jumping directly to station 3. Valves 1 and 2 are clean and functional. Wiring swapped with working stations—no change. Recent power failures occurred. Controller reset attempted.

Diagnosis: Controller Terminal Failure

Since valves and wiring test good (swapped with working zones), and controller reset didn't help, the issue is almost certainly damaged output circuitry for stations 1 and 2 on the controller board. Power surges during outages commonly damage triac outputs for specific stations.

Warranty and Repair Options

• Check if controller is under warranty (Hunter typically 2-5 years)
• Contact Hunter Tech Support: 1-800-733-2823
• If out of warranty, replacement is more cost-effective than repair
• Consider surge-protected power supply for new controller

Surge Protection Recommendations

• Plug-in surge protector rated for 120VAC equipment
• Whole-house surge protector at electrical panel
• Dedicated circuit for controller if possible
• Unplug controller during severe storms if practical

Replacement Controller Options

Hunter Pro-C or HCC (WiFi) are current equivalents. Rain Bird ESP-ME3 or ESP-TM2 are also excellent alternatives. All offer better surge resistance than older models.
