• The user manual specific to your controller model

Having this information ready will prevent interruptions during the programming process and help ensure accuracy.

Step-by-Step Programming Guide

Programming your Hunter sprinkler system follows a logical sequence. Below is a general overview of the steps involved:

1. Set the current date and time
2. Enter zone information and assign names if supported
3. Configure individual zone run times
4. Set program start times
5. Apply seasonal adjustments as needed
6. Review and save all settings

Each of these steps is detailed in the sections that follow.

Setting the Current Date and Time

The first step in programming your Hunter sprinkler controller is to establish the correct date and time. This information is critical because many scheduling features depend on accurate timing. Follow these steps:

1. Press the Program button on the controller.
2. Navigate to the date/time setting using the arrow keys or dial.
3. Enter the current year, month, day, and time using the numeric keypad.
4. Confirm the entry by pressing Enter or OK.
5. Exit programming mode by pressing Run or Back.

Once the date and time are set, the controller will automatically adjust for daylight saving time if enabled.

Configuring Zone Information

After setting the date and time, you need to configure your zone information. This step involves identifying how many zones your system has and assigning them appropriate labels. Here is how to proceed:

1. Press Program and select the zone setup option.
2. Enter the total number of zones connected to your controller.
3. If your model supports naming zones, assign descriptive names such as “Front Lawn” or “Vegetable Garden.”
4. For each zone, specify the type of sprinkler heads installed (rotary, spray, drip, etc.).
5. Save the zone configuration and exit.

Properly labeling zones helps you manage and troubleshoot your system more effectively.

Creating Watering Schedules

Hunter controllers typically allow you to create multiple watering programs, often labeled A, B, and C. Each program can have its own schedule, making it easy to accommodate different plant types or seasonal needs. To create a watering schedule:

1. Select a program (A, B, or C) by pressing the corresponding button.
2. Choose the days of the week when watering should occur.
3. Set the start time for the program.
4. Assign which zones will run under this program.
5. Repeat for additional programs as needed.

For example, you might use Program A for turf areas that require daily watering and Program B for shrubs that only need water twice a week.

Adjusting Run Times for Each Zone

Run time refers to how long each zone operates during a scheduled watering cycle. Setting appropriate run times prevents overwatering and ensures deep root penetration. To adjust run times:

1. Enter programming mode and select the program you want to modify.
2. Choose the zone whose run time you wish to change.
3. Use the arrow keys to increase or decrease the duration.
4. Press Enter to confirm the new value.
5. Repeat for each zone in the program.

As a general rule, lawns need about 10 to 15 minutes per zone, while shrubs and trees may require 20 to 30 minutes depending on soil conditions and sun exposure.

Setting Start Times

Start times determine when each program begins its watering cycle. Most Hunter controllers allow up to four start times per program, which is useful for large properties with multiple zones. To set start times:

1. Select the program and navigate to the start time menu.
2. Enter the desired start time using the numeric keypad.
3. Repeat to add additional start times if needed.
4. Save the settings and return to the main screen.

It is recommended to schedule watering early in the morning to minimize evaporation and reduce disease risk.

Using Seasonal Adjustments

Hunter controllers include a seasonal adjustment feature that allows you to scale run times up or down based on weather conditions. This function is especially helpful during extreme heat or cool periods. To use seasonal adjustments:

1. Access the seasonal adjustment menu in programming mode.
2. Select a percentage value ranging from 5% to 200%.
3. Apply the adjustment to all zones or specific ones.
4. Save and exit.

For instance, during a heatwave, you might increase run times by 25% to compensate for increased evaporation.

Programming Advanced Features

Many Hunter controllers offer advanced features such as rain sensors, freeze protection, and remote access capabilities. These features enhance system efficiency and protect your landscape from adverse weather conditions. To program advanced features:

• Rain Sensor: Connect the sensor wire to the designated terminal and enable the sensor in the settings menu.
• Freeze Protection: Set a temperature threshold below which the system will not activate.
• Remote Access: Download the Hunter Hydrawise app and follow the setup instructions to connect your controller to Wi-Fi.

These features can significantly improve water conservation and system reliability.

Troubleshooting Common Issues

Even with careful programming, issues can arise. Here are some common problems and their solutions:

• Controller won’t turn on: Check the power source and replace batteries if applicable.
• Zones not activating: Verify that zone wires are securely connected and that the correct program is selected.
• Incorrect run times: Double-check the run time settings and ensure seasonal adjustments are not interfering.
• Display is blank or dim: Replace the backup battery and check for loose connections.

If problems persist, consult the user manual or contact Hunter customer support for assistance.
