Hunter's next-generation ACC2 Decoder controller provides powerful irrigation management and monitoring capabilities for complex 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 30 simultaneous solenoids (maximum 20 per output module) at user-specified flow rates.
The all-new design features a full-colour LCD 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.

REAL TIME FLOW MONITORING
This feature permits connection of a flow meter to recognize high or low flow conditions and react automatically to alarms. The controller learns typical flows for each zone of irrigation and then monitors performance during automatic irrigation. When incorrect flows are detected, the controller can identify the faulty station and shut it down. Alarm parameters are user-programmable. Flow totals are recorded in controller memory to report system water usage.
FLOW SCHEDULING / FLOW BUDGETING
The ACC2 has built-in intelligence, with the ability to schedule stations on up to 6 flow zones simultaneously. It continually monitors the system for breaks, leaks and electrical faults, suspending 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.
EASY RETRIEVE® MEMORY
A manual back-up utility that stores complete controller scheduling and setup information in back-up memory. This allows the saved watering schedule to be restored at any time. This can be used to set a controller back to its initial settings after tampering or at the beginning of a new season.
CONDITIONAL RESPONSE
Innovative Conditional Response features use sensor input and other conditions to automatically take pre-programmed actions. Switch from one water supply to another during scheduled irrigation based on level sensors, automatically start specialty programs on sensor input, or create other responses to fit your unique needs with this all-new feature set.
PASSWORD PROTECTION WITH USER MANAGEMENT
Create multiple user IDs with individual PIN numbers and two levels of access. Crew level access allows manual operations and the ability to view programming. Admin level access allows for modifying programming and other settings. When User Management is enabled, operators will be required to enter their pin before operating the controller. You can even review user log-ins in the controller log.
MAINSAFE™ WATER SOURCE PROTECTION
MainSafe™ is an additional level of water source and mainline protection, above the flow zone level. Using a dedicated flow sensor and master valve, the MainSafe™ settings can protect long runs of mainline pipe, allow dedicated lines for manual irrigation, and monitor monthly usage budgets for multiple flow zones.
DELAY BETWEEN STATIONS
Users can program a delay between stations as the controller advances from one station to the next. This delay can range from a few seconds (to permit slow-closing valves additional time to close) to a much longer period of time (to allow pressure tanks time to recharge), based on user requirements.
CALENDAR DAYS OFF, BY DATE
ACC2 allows users to specify Calendar Days Off up to a year in advance. Create a list of dates on which the whole controller will not be allowed to run, regardless of Water Day settings.
SENSOR PROGRAMMABILITY
The ability to specify which program will be shut down in response to a specific sensor alarm. This allows programs unaffected by the sensor to continue automatic operations.
CYCLE AND SOAK
This water-saving feature allows the operator to specify a maximum cycle time for each single station in hours, minutes, or seconds, followed by a minimum soak time, to prevent runoff from slopes or saturated soil. The operator can enter any run time, and the controller will automatically divide it into cycles to allow the water to be absorbed during the soak periods. The feature is adjustable for each individual station or Block of stations for unique soil and site conditions.
