The Hunter DUAL-1 is a single-station two-wire decoder designed for use with I-Core controllers. Field-programmable and built for professional irrigation systems, the DUAL-1 brings reliable two-wire decoding to valve manifolds, helping reduce wire runs and installation labor while keeping serviceability simple.

  • Single-station decoder designed for I-Core DUAL systems; operates one valve output and supports solenoid connections in parallel (max recommended decoder-to-solenoid distance: 100 ft).
  • Two-wire path capability — supports long run distances depending on wire gauge (14 AWG up to 5,000 ft; 12 AWG up to 7,500 ft) to place up to 48 decoder stations per system.
  • Field-programmable at the controller or via the Hunter ICD-HP wireless programmer; decoders do not require serial-number entry.
  • Rugged, IP68-rated waterproof housing suitable for valve box installation with included waterproof connectors; approved to common standards (UL, cUL, FCC, CE, RCM).
  • Use DUAL-S surge protection modules as specified (recommended every 12th decoder or every 1,000 ft) to protect against power surges on long two-wire paths.

DUAL decoders simplify retrofits and new installs by reducing trenching and wire costs while preserving advanced I-Core features like flow monitoring and SmartPort® connectivity. Note: Hunter has marked the DUAL decoder line as discontinued in 2024; Hunter recommends the EZ Decoder System for ICC2/HCC controllers and ICD decoders for ACC2 controllers as replacement options. Check official Hunter documentation and the included manuals for programming, wiring diagrams, and installation guidance. Warranty information is provided by the manufacturer and is based on the decoder manufacturing date code.
