Why does my Hunter Pro-C Controller keep repeating or continuously watering?
If your Hunter Controller is repeating itself or continuously watering, even when it should not be on, it's likely due to too many start times being programmed. Only one start time per active program is required.
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 doesn't my Hunter Pro-C rain sensor shut off the system?
If your rain sensor will not shut off the system, it may be due to an incompatible rain sensor or the jumper was not removed when the sensor was installed. Ensure the sensor is a micro-switch type such as Mini-Clik[®]. Check that the jumper has been removed from the SEN terminals. Confirm proper operation (see “Testing the Weather Sensor” on page 15).
What does “SP ERR” mean on my Hunter Controller display?
If your Hunter Controller display reads “SP ERR,” it indicates that electrical noise is entering the system. Check the SmartPort[®] wiring harness, ensuring the red wire is attached to the AC1 terminal, the white wire to the AC2 terminal, and the blue wire to the REM terminal. If the wires were extended, they will need to be replaced with shielded cable. Contact your local distributor for information on shielded cable.
Why does my Hunter Pro-C Controller display read “NO AC”?
If your Hunter Controller display reads “NO AC,” it indicates that there is no AC power present, meaning the controller is not receiving power. Check to see if the transformer is properly installed.
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.
