Hunter ICM Station Expansion Modules for ICC2 & HCC

Expand the capacity of Hunter ICC2 and HCC irrigation controllers with modular ICM station expansion modules. Available as ICM-400 (4 stations), ICM-800 (8 stations) and ICM-2200 (22 stations), these plug-in modules let you add zones without rewiring so you can scale a system as needs change.

• Flexible increments: Add 4, 8 or 22 stations per module (ICM-400, ICM-800, ICM-2200) to reach up to the controller’s maximum capacity.
• Plug-in installation: Tool-free, plug-in modules that the controller recognizes automatically—install during initial setup or add later.
• Integrated surge protection: Each expansion module includes enhanced surge suppression to protect station outputs and improve reliability.
• ICM-2200 placement rule: The 22-station ICM-2200 must be installed in the controller’s last two module slots; earlier slots should be filled with ICM-800 modules.
• Wide compatibility: Works with ICC2 and HCC controllers; optional EZ-DM decoder expands conventional and decoder outputs for up to 54 stations.
• Remote monitoring & flow: ICC2 systems can use Hunter Centralus (or compatible communication kits) for Wi‑Fi, Ethernet or 4G LTE connectivity and enable flow monitoring with HFS/HC sensors.

These ICM modules provide a straightforward, service-friendly way to grow commercial and municipal irrigation systems—bringing dependable zone expansion, built-in protection, and recognized Hunter compatibility for professional installations.
