Seasonal Adjust, also known by municipalities as Water Index, is used to make global run time changes without reprogramming the entire controller and is perfect for making small changes that are necessary as the weather changes throughout the year.
Please keep in mind that these run times are based on your area's hottest month. You will need to adjust water usage as temperatures cool and heat up. You can either do this manually, through your seasonal adjustment feature on your controller (select models only) or through a weather sensor, such as the Solar Sync.

For instance, during hotter times of the year, the landscape may require a bit more water. Seasonal Adjust can be increased so the stations run longer than the programmed time. Conversely, as fall approaches the Seasonal Adjust can be reduced to allow for short watering durations. This overall percentage based change applies globally to all Run Times on the controller. For example: If your Run Times in the summer are set for 1 hour and you adjust the Seasonal Adjust to 50%, your Run Times will now change to 30 minutes.
