Hunter ICC: New Station Defaults to 1 Minute Instead of 20

Added a new station to an existing Hunter ICC system. When setting run time to 20 minutes, it reverts to 1 minute. All other stations hold 20 minutes correctly.

Complete Installation Checklist

Verify each step was done correctly:

1. Wiring - Two wires to new valve: Common (white) + zone wire from available ICC terminal
2. Valve test - With common connected, touch new zone wire to ICC test port → valve should open
3. Module check - If ICC uses expansion modules, new station must be on a black ICM module

Controller Memory Reset (If All Above Correct)

1. Turn dial to RUN
2. Remove battery
3. Hold Minus (-) + Right Arrow + PRG simultaneously
4. While holding, press and release RESET button on back of front panel
5. Hold all until display flashes 12:00
6. Release - all memory cleared, reprogram from scratch

Why This Happens

The ICC may not have recognized the new station during initial setup, leaving it in a default/undefined state. The full memory reset forces re-initialization of all station parameters.
