Brand: Hunter Industries SKUs: ICM-400 / ICM-800
Product Overview
The Hunter ICM station-module family expands compatible Hunter ICC2 and HCC irrigation controllers. This Big Frog Supply product includes the ICM-400 four-station module and ICM-800 eight-station module. Each plug-in module adds conventional 24 VAC station outputs, allowing the controller capacity to be increased as the irrigation system grows without replacing the complete controller.
Hunter identifies both modules as current ICC2 expansion options with enhanced surge suppression. ICC2 plastic wall-mount controllers can be expanded from eight stations up to 38 stations, while compatible metal and pedestal enclosures can be expanded up to 54 stations. HCC Hydrawise controllers also use ICM-400 and ICM-800 modules for conventional station expansion. The exact allowable module combination depends on the controller family, enclosure, open module positions, base station count, and whether a 22-station ICM-2200 module is installed.
Key Features
- Plug-in conventional station expansion modules
- Compatible with supported Hunter ICC2 and HCC controllers
- Enhanced surge suppression
- Four- and eight-station variants available
- Allows phased controller expansion
- Does not require replacement of the compatible controller enclosure
Variant Options
-
ICM-400: Adds four conventional stations
-
ICM-800: Adds eight conventional stations
Common Uses
- Adding zones to an ICC2 irrigation controller
- Expanding an HCC Hydrawise controller
- Replacing a failed compatible station module
- Phased residential, commercial, or municipal irrigation expansion
Compatibility and Installation Notes
- Confirm the controller is a compatible Hunter ICC2 or HCC model.
- Verify the enclosure’s maximum station capacity and available module positions.
- Disconnect controller power before installing or removing a module.
- Do not exceed the controller’s maximum station count or permitted module combination.
- The ICM-2200 22-station module is a separate product and is limited to one per compatible controller.
- These modules add conventional outputs; decoder operation requires the appropriate decoder hardware.
Frequently Asked Questions
How many stations does each module add?
The ICM-400 adds four stations, and the ICM-800 adds eight stations.
Can these modules be used in a Pro-C controller?
No. Pro-C and HPC controllers use different module families. Confirm the controller model before ordering.
Do these modules include valve solenoids?
No. They add controller station outputs only. Valves, solenoids, and field wiring are separate.
