1. Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your Hunter Sprinkler ICM600 I-Core 6-Station Plug-in Expansion Module. The ICM600 is designed to expand the zone capacity of compatible Hunter I-Core irrigation controllers, allowing for the addition of up to six (6) conventional irrigation zones. Please read these instructions thoroughly before proceeding with installation or use to ensure optimal performance and safety.
2. Safety Information
WARNING: To reduce the risk of electrical shock or injury, always observe the following safety precautions:
- Keep this product out of reach of children.
- Avoid direct contact with skin and eyes during handling and installation.
- Always disconnect power to the irrigation controller before installing or removing the expansion module.

3. Product Overview
The Hunter ICM600 is a plug-in expansion module specifically designed for the Hunter I-Core series of irrigation controllers. It provides an additional six (6) conventional station outputs, allowing you to manage more irrigation zones from a single I-Core controller. This module facilitates easy system expansion without requiring a complete controller replacement.

4. Setup & Installation
- Power Off Controller: Before beginning, ensure the main power to your Hunter I-Core controller is completely disconnected. This prevents electrical shock and damage to the module or controller.
- Locate Module Slots: Open the controller's front panel. Identify the available expansion module slots within the controller. These are typically labeled.
- Insert Module: Carefully align the ICM600 module with an empty slot. The module is designed to fit in only one orientation. Gently push the module firmly into the slot until it is fully seated. Do not force the module.
- Connect Zone Wires: Once the module is securely in place, connect the irrigation zone wires to the corresponding terminals on the ICM600 module. Ensure each wire is stripped appropriately and securely fastened under its terminal screw. Refer to your I-Core controller's main manual for specific wiring diagrams if needed.
- Restore Power: Close the controller's front panel and restore power to the I-Core controller. The controller should automatically detect the newly installed module.
5. Operation
After successful installation, your Hunter I-Core controller will automatically recognize the ICM600 expansion module and the additional six zones it provides. You can then program these new zones using the standard programming interface of your I-Core controller.
- Zone Assignment: The controller will assign sequential zone numbers to the new stations provided by the module.
- Programming: Access the programming menu on your I-Core controller to set start times, run times, and watering days for the newly available zones, just as you would for the controller's built-in zones.
- Testing: After programming, perform a manual test of each new zone to ensure proper operation of the connected valves.
6. Maintenance
The ICM600 module requires minimal maintenance. Regular checks can help ensure its longevity and reliable performance:
- Visual Inspection: Periodically inspect the module and its connections for any signs of corrosion, loose wires, or physical damage.
- Cleanliness: Keep the controller enclosure clean and free from dust, dirt, and insects, which can interfere with electronic components.
- Environmental Protection: Ensure the controller and module are protected from extreme weather conditions, direct sunlight, and moisture, as specified in the I-Core controller's manual.
7. Troubleshooting
If you encounter issues with your ICM600 expansion module, consider the following troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Module not detected by controller | Module not fully seated; power not cycled; faulty module. | Disconnect power, re-seat the module firmly, then restore power. If issue persists, contact Hunter support. |
| New zones not activating | Incorrect wiring; zone not programmed; faulty solenoid; module issue. | Verify zone wiring connections. Check controller programming for the new zones. Test the solenoid at the valve. If the module has an indicator light for the zone, a red light typically indicates a wiring fault or short circuit on that zone. |
| Controller displays error related to module | Module malfunction; communication error. | Power cycle the controller. If the error persists, try moving the module to a different slot (if available) or contact Hunter technical support. |
