Features and Functions

Features and Functions

The Hunter ICC2 sprinkler controller offers a variety of features and functions to help you manage your irrigation system effectively. In this section, we will explore some of the key capabilities of this controller.

Automatic Programs and Customized Scheduling

Hunter ICC2 allows you to create automatic programs to set up repeating watering schedules. You can customize the start times and station run time for each day of the week. This way, you have complete control over your irrigation system and can easily adjust the scheduling according to your needs.

Cycle and Soak

The controller’s Cycle and Soak feature helps you conserve water by breaking up watering sessions into shorter cycles, allowing the soil to absorb water more efficiently. This is particularly helpful for areas with sloping landscapes or compacted soil, as it can prevent runoff and promote deep root growth.

Seasonal Adjustment

Hunter ICC2’s Seasonal Adjustment function allows you to easily modify the watering duration based on the current season or weather conditions. This helps conserve water by reducing the run time during cooler months or increasing it during hotter periods, ensuring that your landscape remains healthy.

Sensor Input

The controller also supports a variety of sensors, such as rain, wind, and freeze sensors, for dynamic and responsive irrigation management. When a sensor is triggered, the system can automatically pause or adjust watering schedules to ensure your landscape’s needs are met without overwatering or wasting water.

P/MV Output

Finally, the Hunter ICC2 sprinkler controller features a P/MV output for managing a master valve or pump. This ensures that the water supply is controlled and optimized for effective watering while protecting your system’s components.

Wiring and Installation

Electrical Specifications

Before you start the installation process, it’s important to familiarize yourself with the electrical specifications of your Hunter ICC2 sprinkler controller. This information can be found in the product manual. Knowing the specifications will ensure the proper wiring and a successful installation.

Transformer Input and Output

The Hunter ICC2 controller requires a specific transformer input and output for its proper functioning:

  • Transformer Input: For the input voltage, make sure you have an AC power source of the required voltage specified in the product manual.
  • Transformer Output: The output voltage must match the rating mentioned in the manual. Misusing the transformer can damage your controller or cause malfunction.

Keep in mind that using a compatible transformer is crucial for the efficient working of your sprinkler controller.

  1. To wire the transformer, first turn off the AC power at the source and verify that it is off.
  2. Follow the steps provided in the manual to connect your transformer:
    • Disconnect the facepack ribbon cable, and remove the facepack.
    • Remove the cover from the junction box.
    • Strip about 0.5″ (13 mm) of insulation from the end of each AC power wire.
    • Route the wires through the conduit opening inside the junction box.

Surge Protection

Protecting your Hunter ICC2 controller from voltage surges and electrical fluctuations is essential. You can use a surge protector to prolong the lifespan of your controller and protect it from potential damages.

  • Install the surge protector as per the manufacturer’s instructions, making sure it is compatible with your controller.

  • ICM-2200: 22-station plug-in module

To install these modules, simply plug them into your controller. Remember, you can add these station output modules at any time after initial installation.

Expansion Module

For larger installations, you might need additional stations, and that’s where the ICM-2200 expansion module comes in handy. Offering an impressive 22-station capacity, the ICM-2200 module helps you truly customize your irrigation setup. By using this module, you’re giving your ICC2 sprinkler controller the power to manage more stations and efficiently water your property.

When installing the ICM-2200, keep in mind that you can only use one ICM-2200 per controller. However, this expansion module still grants you great flexibility in terms of station count and the potential for even larger irrigation setups.
