Hunter ACC Decoders

The two-wire decoder version of Hunter's most powerful commercial controller
ACC-99D uses two-wire decoders to control up to 99 stations without giving up the arsenal of features provided by the ACC. Operating large numbers of valves over long distances, the ACC99D decoder controller takes full advantage of the powerful ACC feature set. Since it's two-wire powered, it also saves copper wire, simplifies troubleshooting, permits rapid addition of new stations, minimizes trenching, and permits remote sensor monitoring over the two-wire path.
