What to do if my Hunter Pro-C display reads “P ERR”?
If your Hunter Controller display shows “P ERR”, it indicates a fault in the wire to the pump start or master valve. Check the master valve or pump start wire for continuity and replace or repair any shorted wires. Also, ensure that all wire connections are secure and watertight.
What does it mean when my Hunter Controller displays a station number and ERR, such as “2 ERR”?
If your Hunter Controller displays a station number followed by “ERR” (e.g., “2 ERR”), there's a fault with the wire leading to that station. Check the station wire for continuity, replace or repair any shorted wires, and ensure all wire connections are good and watertight.
What does “SENSOR OFF” mean on my Hunter Pro-C display?
If your Hunter Controller display reads “SENSOR OFF”, the rain sensor is either interrupting irrigation or the sensor jumper isn't installed. You can slide the Rain Sensor switch on the front panel to the BYPASS position to bypass the rain sensor circuit, or install the sensor jumper.
What does “ERR” mean on my Hunter Pro-C Controller display?
If the display of your Hunter Controller reads “ERR”, it means electrical noise is entering the system. Check the SmartPort® wiring harness. If the wires were extended, they will need to be replaced with shielded cable. Contact your local distributor for information on shielded cable.
What does “NO AC” mean on my Hunter Controller display?
If your Hunter Controller display reads “NO AC”, it means there's no AC power present, and the controller isn't receiving power. Check to see if the transformer is properly installed.
Why does my Hunter Pro-C Controller keep repeating its cycle?
If your Hunter Controller is cycling repeatedly, it's likely due to having too many start times set. Only one start time per active program is needed. Please refer to “Setting Program Start Times” on page 16.
Why won't my rain sensor shut off my Hunter Pro-C system?
If the rain sensor isn't shutting off your Hunter Controller system, it could be due to an incompatible rain sensor, the jumper not being removed when the sensor was installed, or using Manual Single Station Mode. Ensure your sensor is a micro-switch type like Mini-Clik®. Verify that the jumper has been removed from the SEN terminals. Note that Manual Single Station Mode will override the sensor. Use Manual All Station Mode to test the sensor.
How to fix a Hunter Pro-C Controller valve that won't turn on?
If a valve on your Hunter Controller system won't turn on, it could be due to a short in the wiring connections or a bad solenoid. Check the field wiring and replace the solenoid if necessary.
Why doesn't my Hunter Pro-C Controller have a start time for each station?
If the Hunter Controller doesn't have a start time for each station, it's likely due to a programming error or the dial being in the incorrect position. Ensure the dial is in the correct position. You can easily check the total number of stations by placing the dial in the SET STATION RUN TIMES position and pressing the back arrow.
What to do if the display reads “P ERR” on my Hunter Controller?
If the display on your Hunter Controller reads “P ERR,” it means there's a fault in the pump start, master valve, or the wiring for the pump start/master valve. Check the master valve or pump start wire for continuity. Replace or repair the shorted wire and ensure all wire connections are good and watertight.
