Hunter XC Station 1 Won't Activate from Controller—Valve Works Manually

Hunter XC 6-station: Station 1 works manually at valve, not from controller. Other stations fine.

Diagnostic Sequence

1. Activate Station 1, measure 22-26VAC at controller terminal #1 vs COM
2. If NO voltage → controller output failed
3. If YES voltage → check wire continuity to valve
4. Test solenoid (20-60 Ohms)
5. If solenoid good → diaphragm worn, replace
