What to do if Hunter ACC-99D Controller display reads “Attention”?
If your Hunter Controller display reads “Attention,” it indicates an alarm, an active sensor, or trouble in the system. Turn the dial to Data History, select Alarm Logs, and review for individual alarm events. The Controller Log and Station Log may also be useful supporting information when diagnosing problems.
Why Rain or other Clik sensor does not shut down Hunter ACC-99D Controller system?
If a Rain or other Clik sensor does not shut down your Hunter Controller system, it might be due to an incorrect sensor type or connection. Use one normally-closed Clik-type sensor per sensor port (SEN1-4). Verify that one wire from each sensor is connected to + and one to –. It may also be due to incorrect sensor settings for the Program. Turn the dial to Set Sensor Operation and verify the correct response for each program to the sensor (Pause or Suspend).
Why Hunter Controller does not irrigate automatically?
The Hunter Controller might not be irrigating automatically due to several reasons: programming errors (verify all programs Days to Water, Start Times, and Station Run Times); a sensor shutdown (check display for Fault indication and press + for status); Programmable Off being in effect (check display for Off days); or time/date errors (verify controller time and date, including AM/PM/24 hour settings).
How to fix Hunter ACC-99D Controller station that does not irrigate?
If a station on your Hunter Controller does not irrigate, it could be due to a field wiring or solenoid problem. Perform a Manual One-Station start and observe the display and output light. If the light is red, check the solenoid and field wiring, including COM (common) wires. Ensure station outputs do not exceed 0.56A total.
How to fix Hunter ACC-99D Controller with no display?
To fix a Hunter Controller with no display: Check AC power to the controller. Ensure the Facepack is firmly seated and locked, and/or the 9-pin connector is fully connected. Also, ensure the gray ribbon cable is connected from the back of the inner panel to the cabinet. Connect the ribbon cable on the back of the facepack door.
What to do if Hunter ACC-99D does not recognize output module?
If your Hunter Controller does not recognize the output module, and the station size is shown incorrectly, verify that modules are seated all the way up in the wiring compartment and the module lock is On. Also, verify that no module slots have been skipped from left to right. Try re-seating the module and observe the green station light flashing when the module is recognized. If there's no station light or a red light, swap with a known-good module to check for the green light. If the new module works, replace the old module. If the new, known-good module also fails to light, check the gold and silver contacts for dirt, corrosion, or pests.
