Wire and wire installation are key factors in successful decoder installations. Substitution of recommended wire and wire splices is at the installer’s own risk and is a major cause of start-up service troubles. Hunter provides two types of wire for use with decoder systems
ID1 WIRE: Two-conductor, solid-core, twisted, color-coded red and blue, direct burial PE jacket 14AWG/1.6 mm dia. copper wires. Suitable up to 10,000 feet.
ID2 WIRE: Two-conductor, solid-core, twisted, color-coded red and blue, direct burial PE jacket 12AWG/2.05 mm dia. copper wires. Suitable up to 15,000 feet.
- Each two-wire output run of wire is called a "path".
- It is not necessary to connect the paths to one another. Each path runs from the controller to the last decoder in the path, and simply stops there.
- Never connect a wire path from one controller to the wire paths from another controller.
Hunter requires twisted wire meeting the listed specifications on all paths. The twist in the wire is an essential part of surge suppression. As lightning damage is never covered by warranty, it is in the installer’s best interest to share what Hunter has learned in nearly two decades of decoder installations, by using twisted wire that meets all the above specifications. Wire may be substituted provided it meets or exceeds these specifications. The red/blue coding is a convenience for matching the wires to Hunter decoders. Color coding the two different conductors is mandatory.

All connections and splices in the red and blue two-wire path (IDWIRE) must be made with waterproof DBRY-6 or equivalent connectors.
- All Hunter decoders come with DBRY-6 connectors.
- All "-6" connectors are rated to 600 V direct burial and feature high-temperature resistance.
- Additional splices and connections in the two-wire path must be made with equivalent connectors.
When a splice or connection is made, it's important to leave adequate slack in the wires. Leave 5' (1.5 m) slack to keep wire contraction from damaging connections and allow splice removal from the valve box for service or inspection. Wire slack may be coiled neatly or around the inside of the valve box.
You may order Controllers in decoder versions as complete model numbers. Decoder and conventional output modules come in different configurations, so avoid installing them in the same controller at the same time.

Earth grounding of decoder systems is another part of installation that requires planning and careful installation. Properly grounded decoder systems perform very well, even in regions with frequent lightning storms. Poor grounding often results in unnecessary equipment losses and irrigation downtime.
Earth grounding rules for ACC2 Decoder Controllers are the same as for previous ACC/ICD Controllers. When retrofitting a new ACC2 Decoder Controller to an older ICD installation, there's no need to change grounding or field wiring if it was to specification originally. A large ground lug, or clamp, is provided in the controller to connect bare copper wire to earth grounding hardware.
Decoder installations also require earth grounding in the two-wire path itself to protect the decoder investment. Hunter ICD Decoders feature integrated surge suppression, and each is equipped with a bare copper wire for connecting to earth ground hardware.
