Underhill TW-ICC-48 Decoder Module for Hunter ICC Controllers

The Underhill TW-ICC-48 decoder module converts Hunter ICC controllers to 2‑wire operation, expanding system capacity while reducing field wiring and installation time. It installs directly into the ICC module slot and is built for reliable, long-term irrigation control.

• Expands an ICC controller to support up to 48 decoder stations, enabling larger or phased system designs.
• Plug-in installation into the ICC module slot—no controller modifications required for most installs.
• Converts multi-wire systems to 2‑wire architecture, cutting cable runs and lowering labor and material costs.
• Works alongside conventional stations and accommodates ICC programming features such as rain sensors and handheld remotes.
• Durable module construction designed for field reliability; consult the manufacturer manual for warranty and technical specifications.

Use the TW-ICC-48 to simplify upgrades and system expansions on Hunter ICC controllers. Consult the Underhill user manual and wiring guide for installation steps, decoder addressing, compatibility notes, and safety precautions before beginning work.
