The two-wire decoder version of Hunter’s most powerful controller for command of large and sophisticated sites.

The versatility of the ACC controller grows even more powerful with the addition of the all-new, two-wire decoder system from Hunter. ACC-99D uses two-wire decoders to control up to 99 stations without giving up the arsenal of features in the ACC! The powerful overlapping, stacking array of programs, along with ACC’s dual programmable pump/master valve outputs, real-time flow monitoring, and up to four programmable sensor inputs, take full advantage of this controller’s high capacity.
Decoder installations are the fastest growing technology in irrigation control. Why? Because it saves copper wire, simplifies troubleshooting, permits rapid addition of new stations, minimizes trenching, and now, permits remote sensor operation over the two-wire path. The ACC-99D, Hunter's most powerful controller teamed with the most versatile decoders in the industry…an unbeatable combination for large sites with changing needs.
