Controller Frequently Asked Questions

How do I program my controller?

Hunter controllers allow you to start a station or an entire program manually. To do so, turn the dial to Manual Single Station or Manual All Stations, verify that the stations that you want to activate have run time, and turn the dial back to the Run position. When the station or stations finish watering the controller will go back to normal automatic operation.

Watch the four-part video series on the right or follow the links below for more detailed instructions on how to program your controller.

How can I obtain an Owner's Manual for my controller?

Owner's manuals are available on product pages under the "Resources" tab, just below the black "Get Hunter" button. Find your controller from the list at the top of this page to download your owner's manual in PDF format. Other documentation can be found in the Hunter Resource Library. Click here to view all Controllers owner's manuals.

Why does my irrigation system cycle over and over?

The most common reason for systems to cycle more than once is having programmed too many Start Times. Hunter controllers allow you to setup multiple Start Times to run programs more than once a day. At each Start Time the controller will cycle through all the Station Run Times on that given program. You can eliminate Start Times using the arrow buttons and finding OFF in between 11:45pm and 12:00am or midnight.

My controller has a blank display, what do I do?

A blank display is a typical symptom that the controller is no longer receiving power from the outlet or breaker to which it is wired. Voltage tests can be performed on the two inner 24VAC terminals. Confirm that you have 24VAC across these terminals. The controller is receiving AC Power.

Why does my controller display show "NO" or "NO AC"?

The NO or NO AC display is a diagnostic message telling you that the controller has stopped receiving AC power. The controller is running on the power supplied by the backup battery.

Check the power source by plugging a lamp or radio into the wall outlet to verify there is power at the outlet. If your controller is not plugged into a wall outlet, the power source is hardwired. Controllers that are hardwired to the power source will need to be tested by a qualified electrician.

If you do not have power to the outlet, check all wall switches, timers, or power strips that may be connected to the outlet. Have an electrician check your GFI, circuit breaker, and electrical outlet if you do not have power to the outlet.

If you can verify that you have power to the outlet, disconnect the backup battery from the controller.

If the display goes blank after removing the battery, the transformer could be damaged and may need to be replaced. A transformer can be tested with a voltmeter. Normal voltage output is 24-26 Volts AC.

What is seasonal adjustment and how do I set it?

Seasonal Adjust is used to make global run time changes without re-programming the entire controller. This feature is perfect for making small changes that are necessary as the weather changes. For instance, during hotter times of the year, the landscape may require a bit more water. Seasonal adjust can be increased so that the stations will run longer than programmed time. Conversely, as fall approaches, the seasonal adjust can be reduced to allow for short watering durations.

Where can I get a replacement key set for my Hunter controller?

You can visit the Hunter Online Store or visit a Hunter Distributor and order the keys as part #122516.

 

My Hunter SRC controller reverts back to the current time display when I try to run a station, what is wrong with my controller?

Over the life span of an SRC controller, surges and electrical strikes can wear on the internal components of the SRC's circuit boards. Unfortunately there is not much you can do to salvage the controller after this happens.

With the SRC discontinued an X-Core would be a comparable replacement.

How do I get out of the Interval mode on my Hunter controller?

Under the Water Days or Days to Water dial position on your controller you have three options. You can have the program run on specific days, an odd/even schedule, or an interval schedule.

To move out of the Interval mode and back into one of your other two options simply continue pressing the right or left arrows. Eventually you should see either a drop of water above the individual days or a drop with a circle around it and a line through it. Now you are in Day of the Week mode and the days of activation will need to be chosen.

The arrow button will move your blinking selection icon from day to day, the plus will activate a day, the minus button will deactivate a day.

How do I eliminate the delay between stations on my Hunter controller?

To eliminate a delay, start with the dial in the RUN position. Push and hold the minus button, while holding the minus button turn the dial to Set Station Run Times. The delay will appear, zero the delay out using the minus button. After doing so simply turn the dial back to RUN and the delay is eliminated.

What is the little sprinkler icon that flashes on my display?

The sprinkler icon flashes when the controller is outputting power to the station terminal or terminals activating a station. If the icon is blinking with an umbrella on the display, as in the SVC, the rain sensor's circuit has been broken and is not allowing for watering even though scheduled watering should be occurring.

Common error codes and how to troubleshoot them

Error Code Problem Troubleshooting Technique

P ERR

Amperage over draw on the pump start or master valve circuit.

Use a Volt Ohm meter and check the amperage load on the pump start/master valve circuit, and compare your reading with the maximum master valve output on your Hunter controller. This number can be found in the controller pages in our catalog under “Specifications” or on the web site on the individual Controller Product pages.

(Station Number) ERR

Amperage over draw on a particular station circuit.

Use a volt ohm meter and check the amperage load on the station circuit, and compare your reading with the maximum station output on your Hunter controller. This number can be found in the controller pages in our catalog under “Specifications” or on the web site on the Controller Product pages.

ERR

(when nothing is plugged into the “SmartPort”)

Noise entering the controller through the “SmartPort” wiring.

To fix this ERR message; install a shielded SmartPort wiring kit (Hunter Part #SRR-SCHW), available from your locally authorized Hunter distributor.

ERR

(when the ICR or ROAM remote receiver is plugged into the “SmartPort”)

The “SmartPort” may be wired incorrectly.

To fix this ERR message, rewire the “SmartPort” wiring harness. On the Pro-C and ICC controllers; starting from the bottom and going up, the red wire connects to the first “AC” terminal screw, the white connects to the second “AC” terminal screw and the blue wire connects to the “REM” terminal screw. On the SRC controllers, starting from the left and going to the right, the red wire connects to the first “AC” terminal screw, the white connects to the second “AC” terminal screw and the blue wire connects to the “R” terminal screw.
