Hunter ACC2 Advanced Flow Management 12 Station Outdoor Controller


Hunter ACC2 Advanced Flow Management Outdoor controller

The multi-flow monitoring and management capabilities of ACC2 make it the best choice for complex projects.

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

At its core, the ACC2 has a powerful transformer, allowing it to safely run up to 14 valves simultaneously, bringing maximum efficiency to large watering schedules. The ACC2 can be configured for any commercial project, from 12 to 54 stations, with up to 6 flow meter inputs, and up to 6 pump/master valve outputs. Its easy-to-read color backlit display and unique reversible facepack make program setup and diagnostics fast and efficient.

The ACC2 has built-in intelligence, with the ability to maintain preset flows on up to 6 flow zones simultaneously. It continually monitors the system for breaks, leaks and electrical faults, interrupting irrigation and pinpointing the source should problems arise. It can even respond to sensor input with specific actions like switching water supplies when water levels drop, or initiating a program when soil moisture is low, and other creative special applications.

The ACC2 offers extreme flexibility with 32 independent programs, 10 start times, and a variety of overlapping, stacking, and flow management configurations. Innovative Conditional Response features use sensor input and other conditions to automatically take pre-programmed actions.  Optional external alarm output alerts maintenance personnel to alarm conditions, and the available Wi-Fi module works with nearly any mobile device.

With the ACC2, you’ve got the most advanced commercial controller available, with maximum capability for your largest projects.
