Understanding Hunter Sprinkler System Components

Understanding Hunter Sprinkler System Components


The controller is the brain of your Hunter sprinkler system. It automates the watering process by allowing you to set a schedule and duration for watering your lawn. Controllers can be used in both residential and commercial settings.

Irrigation Controller

Irrigation Controller

An irrigation controller is a specific type of controller designed for managing the water distribution in your sprinkler system. Hunter offers various models to suit different needs, ranging from simple to advanced features.


Valves control the flow of water to different areas of your lawn. Each zone in your system will have a valve that opens and closes to water that specific area. Proper valve functioning is essential for efficient and effective irrigation.

Backflow Device

A backflow device is a critical safety component in any irrigation system, preventing contaminated water from flowing back into your home’s water supply. It is essential to have a correctly installed and functioning backflow device to protect your family’s health.


The display on your Hunter sprinkler system controller provides you with essential information about your system’s status and settings. It allows you to easily adjust and monitor watering schedules, duration, and other system parameters.

Control Dial

The control dial is a user-friendly interface that makes it easy to navigate and adjust settings on your sprinkler system controller. This dial allows you to select different modes, set watering schedules, and more with just a few simple turns.

  • Controller: Automates watering process
  • Irrigation controller: Manages water distribution
  • Valves: Control water flow to specific zones
  • Backflow device: Prevents contaminated water from entering the water supply
  • Display: Provides essential system information
  • Control dial: User-friendly interface for adjusting settings

By understanding these components, you can better maintain and troubleshoot your Hunter sprinkler system to ensure optimal performance.

Troubleshooting Common Issues

Wiring and Transformer Problems

Check the wiring compartment for any loose or damaged wires. Make sure all connections are secure and watertight. Inspect the transformer to ensure it is functioning properly. It may be helpful to use a multimeter to test the voltage of your transformer.

  • Make sure the RED (AC1), WHITE (AC2), and BLUE (REM terminal) wires are properly connected.
  • Verify the wire size is appropriate for your sprinkler system and replace if necessary.

Valve and Coverage Complications

Valve issues are a common source of problems in a sprinkler system. Follow these steps to troubleshoot valve and coverage complications:

  1. Inspect the valves for any debris, and clean if necessary.
  2. Make sure the valves are opening and closing properly.
  3. Check for leaks around the valves and pipes, and repair if needed.
  4. Ensure the sprinkler heads are properly adjusted to provide the right coverage for your lawn.

Battery and Power Supply Difficulties

If your Hunter sprinkler system is experiencing power supply problems, it may be due to a weak or dead 9V battery. Always keep a spare battery handy, and replace the battery if the unit is not holding proper time or data.

  • Check the battery compartment for any signs of corrosion or damage, and clean it with a soft cloth if necessary.
  • Inspect the power supply connections and make sure they are securely plugged into the unit.
  • Examine the logs in your controller to see if there are any error messages or abnormal events that may indicate a power issue.

Remember, if you continue to experience issues with your Hunter sprinkler system, it’s important to consult your user manual or contact a qualified technician for assistance.

Additional Features and Useful Tips

In this section, we will explore some additional features and useful tips for your Hunter Sprinkler System, helping you make the most out of it.

Seasonal Adjust and Manual Watering Modes

Seasonal Adjust is a convenient feature that allows you to easily modify your irrigation schedule based on the current season. To use this feature, simply turn the Seasonal Adjust Dial position to your desired percentage. For example, if you want to reduce the watering duration by 50% for the entire system, set the dial to 50%. The controller will automatically adjust the watering times accordingly.

Manual Watering Modes help when you need to water specific areas of your lawn or garden without changing the programmed schedule. Simply switch the dial position to Manual All Station and start watering as needed. Remember to set the dial back to Automatic or Off mode when you are done.

Understanding Test Programs and Flow Totals

Test Programs are designed to help you identify issues in your sprinkler system, such as leaks and broken sprinkler heads. To start a test program, press the PRG button until you see 12:00 AM, then set the dial to TEST and press Enter. The test program will run each zone for a short period, allowing you to inspect and analyze the performance of each sprinkler head.

Flow Totals are useful for monitoring your water consumption and may help you lower your water bill. To access flow totals, press and hold the Flow Totals button for three seconds. The display will show the accumulated flow rate (in gallons or liters) for each zone.

Saving and Using Easy Retrieve Backup

The Easy Retrieve Backup feature allows you to save your current program settings for easy retrieval in case of a power outage or system reset. To save your settings, press and hold the Easy Retrieve button until you hear a beep. Your settings have now been saved.

To load your saved settings, press and hold the Easy Retrieve button again until you hear two beeps. The controller will now restore your settings, ensuring that you don’t have to reprogram your irrigation schedules from scratch.

By utilizing these additional features and tips, you can optimize your Hunter Sprinkler System and maintain a healthy, lush landscape throughout the year.

Dealing with Installation and Repairs

Identifying Defective Components

When dealing with Hunter sprinkler systems, it’s crucial to identify any defective components to ensure proper functionality. Some common issues to look out for may include:

  • Malfunctioning valves causing insufficient water pressure
  • Damaged sprinkler heads, affecting coverage and distribution
  • Faulty controllers (Pro-C, ICC, SVC, Node) leading to inadequate watering days

To spot these issues, inspect your irrigation system periodically, paying close attention to water flow, coverage, and control panel functions.

Understanding Proper Installation Techniques

Properly installing your Hunter sprinkler system is essential, as it affects long-term efficiency and the overall health of your lawn. When carrying out installation or repairs, consider the following tips:
