Hunter ACC2 Decoder Controller

Powerful. Intelligent. Flexible. Hunter’s new ACC2 controller delivers advanced water management to meet the demands of large-scale commercial projects.

The ACC2 Decoder controller is specifically designed to manage Hunter ICD decoders on large projects, and is expandable to 225 stations. The controller offers extreme flexibility, with 32 independent programs, 10 start times, and a variety of overlapping, stacking, and management configurations.

The powerful Flow Manager takes full advantage of sophisticated irrigation designs, watering as much as possible in the shortest possible amount of time —up to 20 simultaneous solenoids.

The all-new design features a full-color LED display in a reversible facepack that operates all functions in either position, making field service a breeze. Finally, advanced features such as Flow Monitoring deliver fast diagnostics of abnormal flow conditions and accurate histories for up to six flow zones.

For the ultimate reliability in large-scale commercial irrigation management, the ACC2 Decoder controller is second to none.
