3. Installation & Wiring Best Practices
- Location: Mount controller in a sheltered, accessible spot—avoid direct sunlight and moisture.
- Power Supply: Connect to a dedicated 120/230 VAC circuit with proper grounding.
- Valve Wiring: Use stranded #14–#18 AWG cable; colour-code common and station wires for clarity.
- Sensor & Flow Meter Hookups: Follow wiring diagrams—use common ground for rain, soil-moisture, and flow sensors.
- Network Setup: For Hydrawise models, connect to local Wi-Fi (2.4 GHz) or wired LAN as directed.

4. Programming Your Controller
- Basic Schedule:
- Set current date/time.
- Define watering start times (Multiple per day).
- Assign run durations per station.
- Set watering days (odd/even, interval, custom days).
- Advanced Options:
- Seasonal Adjust: Adjust all station durations by a percentage.
- Rain Day Skip: Manually suspend or use sensor-based auto-skip.
- Cycle & Soak: Break long runs into cycles to prevent runoff.

5. Maintenance & Troubleshooting
| Issue | Likely Cause | Solution |
|---|---|---|
| No Power/Display Blank | Blown fuse or tripped breaker | Replace fuse; reset breaker |
| Wi-Fi Connection Lost | Network changes or weak signal | Reconfigure network; move router closer |
| Valve Won’t Activate | Faulty solenoid or wiring break | Test solenoid resistance; repair cable |
| Rain Sensor Not Skipping | Sensor mis-wired or bypassed | Check wiring; ensure “rain sensor” setting ON |
| Hydrawise Login Errors | Incorrect credentials or firmware issue | Reset password; update controller firmware |

Top 10 Questions & Answers
- Which Hunter controller suits a small garden?
X-Core (4–8 zones) or NODE (6–36 stations) for battery-powered convenience. - How do I connect Solar-Sync?
Mount sensor outdoors; wire to sensor terminals; configure in controller menu. - Can I adjust watering remotely?
Yes—with Hydrawise-enabled Pro-HC or ICC series via web/app. - What maintenance does the controller need?
Annual firmware updates, fuse inspections, and terminal tightness checks. - How do I expand my stations?
Add SM-X or ST-WM modules—simply snap onto ICC or MAXI-IP backbone. - Does Hunter offer flow monitoring?
Yes—connect flow meter to dedicated terminals; set flow rates for leak detection. - Can I use a rain sensor?
Yes—wire to RS input and enable “rain sensor” mode in program settings. - What’s Cycle & Soak?
Splits long watering into shorter cycles with soak intervals to improve infiltration. - How to reset Hydrawise password?
Use “Forgot Password” on Hydrawise site; follow email link to reset. - Is professional installation required?
Basic models can be DIY-installed; complex Hydrawise or large-zone systems may benefit from a licensed irrigation specialist.
