PROBLEM
CAUSES
SOLUTIONS
There is no display.
Check AC power wiring.
Correct any errors.
The display reads "ERR".
Electrical noise is entering the system.
Check the SmartPort
®
wiring harness.
If the wires were extended then they
will need to be replaced with shielded
cable. Contact your local distributor for
information on shielded cable.
The display reads "P ERR".
There is a ground fault in the wire to the
pump start or master valve.
Check the master valve or pump start
wire for continuity. Replace or repair
the broken wire. Check that all wire
connections are good and water tight.
The display reads a station number
and ERR, such as "2 ERR".
There has been a ground fault with the
wire leading to that station.
Check the station wire for continuity.
Replace or repair broken wire. Check that
all wire connections are good and water
tight.
The display reads "NO AC".
There is no AC power present.
Check to see if the transformer is properly
installed.
The display reads "SENSOR OFF".
The rain sensor is interrupting irrigation
or not installed.
Slide the Rain Sensor switch on front
panel to the
BYPASS
position to bypass
rain sensor circuit.
Rain sensor will not shut off system.
Make sure sensor is micro-switch type
such as Mini-Clik
®
. Rain Bird
®
,
Rain Check™ is not this type and will not
work. Check that the the jumper has been
removed from the
SEN
terminals.
The controller recognizes 15 stations
all the time.
Make sure AC power is connected.
Reset controller using method described

The controller does not respond to all
stations. Example, the controller has
12 stations but the display will only go
to 6 stations.

Turn off the power to the controller and
remove the battery. Check all module
connections to the controller. Power the
controller back up. The microprocessor
will recognize all modules.
TROUBLESHOOTING GUIDE
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. 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.
