Programming Stations and Zones

Each zone connected to your Hunter XC controller needs to be configured with a run time. Here’s how to assign durations:

1. Press PRG to enter programming mode.
2. Navigate to the Station Run Time menu.
3. Select a station number (e.g., Station 1).
4. Enter the desired run time in minutes using the + or – buttons.
5. Press Start/Next to move to the next station.
6. Repeat for all active stations.
7. Press Start/Next until you exit programming mode.

Typical run times range from 5 to 30 minutes depending on plant type, soil condition, and sun exposure.

Creating Watering Schedules

After assigning run times, create watering schedules that determine when each zone activates. Follow these steps:

1. Press PRG to enter programming mode.
2. Select Start Times from the menu.
3. Choose a program (A, B, or C).
4. Set the first start time using the + or – buttons.
5. Press Start/Next to add additional start times if needed.
6. Navigate to Watering Days and select which days each program runs.
7. Assign individual stations to programs under the Station Program Assignment menu.
8. Exit programming mode by pressing Start/Next until the main screen reappears.

You can use multiple programs to accommodate different plant types or watering frequencies within the same system.

Using Seasonal Adjustment

The seasonal adjustment feature allows you to increase or decrease all station run times simultaneously based on changing weather conditions. To use it:

1. From the main screen, press the Info (i) button.
2. Scroll to Seasonal Adjust using the + or – buttons.
3. Enter a percentage value (e.g., 80% for reduced watering in spring).
4. Press Start/Next to confirm.

For example, setting the adjustment to 120% increases all run times by 20%, which is useful during hot summer months.
