The ACC brings the versatile features of modularity to the most advanced large-scale commercial controller in the Hunter line. The adaptable design not only allows configuration to the number of stations you desire, it also makes it easy to upgrade to two-way communication with a Hunter Central Control System. What truly sets the ACC apart is its sheer power. Intelligent overlap settings and its powerful transformer allow ACC to run up to 6 programs simultaneously, packing the most watering into the shortest water window. Real time flow monitoring allows the controller to dynamically respond to overflow conditions by station, and track system water use. The ACC boasts a total of 6 independent and 4 custom programs and the ability to assist the water manager in conforming to watering windows. Plus, the ACCs large backlit LCD display offers the user a convenient means to personalize on-screen station and program names. ACC also has built-in support for the water-saving Solar Sync sensor.

WATERSENSE® SMART WATERING CONTROLLER BY ADDING SOLAR SYNC
By adding a Solar Syncto your Hunter controller, it transforms into a smart controller using local weather conditions to tailor watering schedules to actual conditions on the site. A Hunter controller with Solar Sync has been independently proven to have a detailed list of water saving features and has been approved by the EPA as a WaterSense Smart Watering Controller.
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. Used with a normally-closed Master Valve. Alarm parameters are user-programmable. Flow totals are also recorded in controller memory to report system water usage.
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.
ONE TOUCH MANUAL START AND ADVANCE
Allows the user to manually start/test any station by simply pressing and holding the right arrow button, and then adding a run time to the appropriate station.
PROGRAMMABLE RAIN DELAY
The Programmable Rain Delay feature incorporates a user specified number of days to keep the controller in the OFF mode, then allows for the system to automatically revert back to scheduled irrigation. This will prevent watering during an extended period of inclement weather, but will resume watering automatically without requiring a return visit to the controller. The controller displays the number of days remaining before watering resumes.
This feature offers protection against unreliable power, retaining current time, date, and program data.
AUTOMATIC SHORT CIRCUIT PROTECTION
Automatic short circuit protection is a feature found in all Hunter AC powered controllers. This feature automatically detects electrical faults, which are typically caused by wiring issues. Stations that have shorts detected are skipped, allowing watering to continue for those stations where faults are not detected. There are no fuses to blow or internal circuit breakers to trip, so complete irrigation system shutdown is avoided.
SEASONAL ADJUSTMENT: GLOBAL, BY PROGRAM AND SOLAR SYNC FOR ACC
This feature allows for quick adjustments to irrigation run times through a percentage scale. During peak season, set the seasonal adjust to 1%. If weather conditions require less water, enter the appropriate percentage value (i.e. 5%) to cut down irrigation run times without the need to adjust each station in the program. The ACC offers three different ways to use Seasonal Adjustment to reduce water usage:
Global: Provides a seasonal adjustment value to all selected programs.
By Program: Each program may be assigned a different fixed Seasonal Adjustment value, if necessary.
Solar Sync: When connected to the ACC, the Solar Sync ET sensor implements an automatic daily adjustment based on measured local weather.
DELAY BETWEEN STATIONS FOR I-CORE AND ACC
A delay in watering between individual stations as the controller moves from one to the next. The delay may range from a few seconds, to permit slow-closing valves time to shut down, or much longer to allow pressure tanks, etc., to refill or recharge. In ACC and I-Core, Delay Between Stations may be set by individual program.
SENSOR PROGRAMMABILITY FOR ACC
Each of the ACC's 4 Clik sensor inputs can be configured to shut down any of the 6 automatic programs in Suspended or Paused modes, offering a variety of sensor response options for different conditions.
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 for unique soil and site conditions.
NO WATER WINDOW
User-specified periods of time during which the controller will not allow automatic irrigation. No Water Window can be used to comply with local watering restrictions or to prevent conflicts with pedestrian traffic. This setting does not affect manual watering options for local maintenance.
SOLAR SYNC DELAY
Solar Sync Delay allows the installer to specify a number of days before automatic weather adjustment from the Solar Sync sensor begins, as well as a global percentage to use during the delay period. This allows a period of non-adjusted irrigation for grow-in or plant establishment purposes, without requiring a return visit to the site to enable the Solar Sync water saving feature.
SIMULTANEOUS STATION GROUPS
Allows for the ability to group stations into larger irrigation units that run together within automatic programs. This permits consolidation of large systems into fewer items to program and can be used to control system flow in high capacity installations.
TOTAL RUN TIME CALCULATOR
This feature adds up all run times, and calculates the total duration of a program to instantly display the full length of an irrigation cycle. This information can be used to determine the time when watering will end.
