Hunter Pro-C Module Recognition Issue: Secure Expansion Modules Properly

Pro‑C (10 yr) Only Recognizes Zones 1‑4 in Programming; Manual Runs All 7

The expansion modules (for zones 5‑7) are not fully locked into the main board.

  1. Unplug controller power and remove battery.
  2. Firmly press each module until it clicks into place.
  3. Reinstall battery, restore power, and test programming.

If the issue persists, the controller may need replacement (new Pro‑C fits same footprint).
