Hunter Hydrawise Pro-HC 24-Zone Indoor Wi-Fi Controller (PHC2400i)

Pro-C and ICC to Hydrawise: Retrofit Guide for HOA Boards

Most associations already own Hunter Pro-C or commercial ICC / ICC2 cabinets in pump rooms and entry walls. An HOA Hunter controller upgrade to Hydrawise often means changing the facepack—not trenching new wire. This retrofit guide is written for board packets and property managers.

Hub: HOA irrigation controller upgrade. Deep dives: Pro-C → Hydrawise · ICC/ICC2 → Hydrawise · HPC-FP vs PC-WIFI comparison.

Why retrofit beats rip-and-replace

  • Reuse the enclosure, transformer, and station wiring
  • Minimize landscaper downtime (often hours, not days)
  • Lower capital cost versus new pedestals everywhere
  • Still gain app control, Predictive Watering, and reporting

Pro-C path: HPC-FP facepack

If the wall unit is a Pro-C / HPC family cabinet in good condition, the HPC-FP Wi-Fi facepack is usually the board’s best first vote. It converts the controller to Hydrawise while keeping the existing station modules.

Board checklist:

  1. Confirm model label (Pro-C / PC-series compatibility)
  2. Verify Wi-Fi reach at the cabinet
  3. Photograph station labels before the swap
  4. Budget rain/freeze sensor if missing

ICC / ICC2 path: HCC-FPUP and 941500

Commercial ICC and ICC2 metal cabinets commonly take the HCC-FPUP retrofit kit or the 941500 HCC-FP facepack depending on the exact panel generation. Match the kit to the cabinet before the meeting—wrong facepacks delay projects.

When to buy a new Pro-HC or HPC instead

Choose a new enclosure when the cabinet is corroded, flooded, undersized, or on a platform Hydrawise cannot retrofit cleanly. Mid-size sites often land on Pro-HC 12-zone; modular growth favors HPC-400.

Economics for the reserve study

Facepack projects concentrate spend in hardware + short labor blocks. New multi-controller campuses cost more but can include flow meters and outdoor APs in one mobilization. Ask for both options in the Quote Center so the board can compare NPV against water savings.

Frequently Asked Questions

Will residents notice downtime?

Usually only for the swap window. Schedule during cool mornings and temporarily pause irrigation; restore Hydrawise schedules the same day.

Is PC-WIFI the same as HPC-FP?

No. PC-WIFI and Centralus paths differ from full Hydrawise facepacks. Read the comparison article before voting.

Do we keep existing rain sensors?

Often yes—verify wiring and compatibility during the audit. Replace failed sensors while the cabinet is open.
