To initiate the Hunter Quick Check test procedure:
Press the , , and buttons simultaneously. In the standby mode, the LCD will display all
segments (helpful when troubleshooting display problems).
Press the button to begin the Quick Check test procedure. The system will search all stations to
detect a high current path through the station terminals. When a field wiring short is detected, an ERR
symbol preceded by the station number will momentarily flash on the controller LCD display. After the
Hunter Quick Check completes running this circuit diagnostic procedure, the controller returns to the
automatic watering mode.
Clearing Controller’s Memory/Resetting Controller:

If you feel that you have misprogrammed the controller, there is a process that will reset the memory to
factory defaults and erase all programs and data that have been entered into the controller. Press and
hold the button. Press and release the RESET button on the back of the front panel. Wait until the

HUNTER ICC QUICK CHECK AND RESET FEATURES
Clearing Non Volatile Memory:
Turn the dial to RUN
Press the , ,and buttons down simultaneously.
Whilst the 3 buttons are being held down, momentarily press and release the RESET button
Release the , ,and buttons. The LCD display will show 12.00am
Test Program:
The ICC allows the user a simplified method for running a test program. This feature operates each
station in numerical sequence, from the lowest to the highest. You can start with any station. This is a
great feature to check the operation of your irrigation system.
To initiate the test program:
Press and hold the button. The station number will be flashing.
Press the or button to scroll to the station you would like the test program to start with. Use
the or button to set the run time up to 15 minutes. The run time needs to be entered only once.
After a 2 second pause, the test program will begin.
Hunter Quick Check™:
Irrigation professionals are continuously looking for ways to more efficiently and effectively diagnose
programs in the field. Instead of having to physically check each field wiring circuit for potential
problems, the user can run the Hunter Quick Check™ circuit test procedure. This circuit diagnostic
procedure is very beneficial because of its ability to aid in quickly identifying “shorts” commonly caused
by faulty solenoids or when a bare common wire touches a bare station control wire.

To initiate the Hunter Quick Check™ test procedure; Press the , , , buttons. In the
standby mode, the LCD will display all segments (helpful when troubleshooting display problems). Press
the button to begin the Quick Check™ test procedure. Within seconds, the system searches all
stations in an effort to detect a high current path through the station terminals. When a field wiring
short is detected, an ERR symbol preceded by the station number will momentarily flash on the
controller LCD display. After the Hunter Quick Check™ completes running this circuit diagnostic
procedure, the controller returns to the automatic watering mode.
