Nelson/Hunter Controllers: Can't Program Stations 5 & 6

Two Controllers, Same Issue: Stations 5 & 6 Unprogrammable

Nelson 6-station lost memory; new Hunter XC-6 won't program stations 5 & 6. Manual run works for all zones. Wiring checked, insulators replaced.

Diagnostic Step

Swap wires: connect valve 5 wire to terminal 4 (or 3) on controller. If it programs/runs on another terminal, the controller terminal is bad. If not, the wire/valve has an issue (but manual works, so unlikely).

Next Steps

Re-read Hunter manual carefully; follow programming sequence exactly.
Call Hunter support: 800-733-2820.
If terminal-specific, controller may have a defective output driver for stations 5/6.

Odd Coincidence

Two different controllers with same station limitation suggests a wiring or installation factor, but manual operation working makes it puzzling.
