Installation

Installing the Hunter ICC2 is straightforward for anyone comfortable with basic electrical and irrigation wiring, but you might want a pro for larger systems or when integrating two-wire decoders. The controller supports both multi-wire installations and the EZ-Decoder two-wire system, offering flexibility depending on how complex your valve layout is.

Pre-installation checklist

Before you start, make sure you have the mounting screws, appropriate wire gauge for your valve runs, and optional modules if you plan to expand immediately. Also check your local codes to ensure compliance if you’re installing in a commercial or regulated environment.

Step-by-step basics

You’ll mount the cabinet, run the wires to the appropriate terminals, connect the transformer and sensors, and then set program parameters on the dial and LCD. If you choose the EZ-Decoder system, you’ll strip only two conductors for the whole system and connect decoders at each valve location, which reduces trenching and simplifies wiring for large installations.

Setup and programming

Programming the ICC2 is friendly for both homeowners and pros. The dial-based interface is intuitive, and the controller supports four separate programs and up to eight start times per program, so you can run different zones with unique schedules and frequencies.

Programming modes and schedule flexibility

You can create varied schedules for turf, flower beds, trees, and vegetable gardens using separate programs and different weekly, interval, or odd/even day options. You’ll find it easy to tailor run times per zone to soil type, slope, and plant needs.

Seasonal adjustments and water savings

With the Solar Sync sensor compatibility, the controller can automatically adjust watering based on local evapotranspiration (ET), so you’ll reduce overwatering during rainy periods and increase it during dry spells. The built-in flow monitoring provides another layer of water management by alerting you to leaks and abnormal usage patterns.

Flow monitoring explained

One of the standout features you’ll benefit from is the integrated flow monitoring system. It tracks real-time water flow and can automatically notify you (or shut down the system if configured) when flow rates indicate a leak, broken head, or sudden pressure change.

How flow monitoring helps you

Flow monitoring can prevent costly water waste and landscape damage by catching problems early—before they become large-scale issues. You’ll reduce your water bills and avoid plant stress from unnoticed over- or under-watering.

Setup and alerting

You’ll usually install a flow sensor in the main line feeding the controller zones; the ICC2 reads that sensor to compare current flow against expected values for active zones. If the controller detects deviation beyond configurable thresholds, it can generate an alarm, skip a zone, or lock the system out until you investigate.

Expandability and modular options

If you’re starting with a small property but anticipate growth, the ICC2’s modular expansion is invaluable. You can begin with the 8-station base and add modules or decoders to reach up to 38 stations without replacing the entire controller.

Adding stations with modules

Optional plug-in station modules allow you to add 8 or more stations at a time depending on the configuration you choose. This means you can budget your upgrades over time while keeping a consistent control platform.

Two-wire EZ-Decoder system

If you prefer minimal wiring, the EZ-Decoder system uses two conductors that run from the controller to each decoder at the valve location, greatly simplifying installation on larger landscapes. You’ll save on trenching and wire costs, and you’ll find future expansion considerably easier.

Compatibility with sensors and accessories

The Hunter ICC2 is designed to work seamlessly with popular Hunter accessories, which gives you more control and automation options. You can connect the Solar Sync sensor for weather-based adjustments, use the ROAM remote for on-site manual control, and integrate with decoders for two-wire installations.

Solar Sync for automatic adjustments

When paired with Solar Sync, the controller automatically modifies run times based on real-time weather and historic ET patterns. You’ll make smarter watering choices without daily tinkering.

ROAM remote and professional control

If you need to manually run zones from a distance, the ROAM remote gives you handheld control—handy for contractors and homeowners who are often working on the landscape. This is particularly helpful for spot watering or testing individual zones during maintenance.

Performance and reliability

In day-to-day operation, the ICC2 performs like a professional-grade controller designed for heavy use. The dial-driven interface reduces accidental programming mistakes and the hardware has a proven track record in residential and commercial settings.

Real-world operation

You’ll notice that programs run reliably even when power blips occur; the internal memory retains schedules so you don’t have to reprogram after minor outages. The built-in transformer and robust terminal design minimize connection issues over time.

Durability in different settings

Whether you mount the controller in a garage, on an exterior wall, or in a small service cabinet, it resists the humidity and temperature swings common in outdoor environments. For coastal or very humid climates you should still inspect seals and connections periodically to guard against corrosion.

Maintenance and troubleshooting

Keeping the ICC2 running smoothly requires routine checks of valve wiring, sensor integrity, and occasional software confirmations. Most maintenance tasks are straightforward, and the controller provides clear indicators for fault conditions.

Routine checks you should perform

Check your flow sensor and valve wiring at least once a season, verify that your seasonal adjustment sensor is clean and unobstructed, and run manual cycle tests to ensure each zone activates correctly. You’ll also want to back up your programming or document settings in case you need to swap controllers.

Common issues and quick fixes

If a zone won’t run, check valve wiring continuity and the fuse or transformer output first. For flow monitoring alerts, confirm the sensor is properly installed and calibrated, and verify that no recent landscape changes (like a new drip line) are skewing expected flow values.
