What is the primary function of seasonal adjustment in a conventional irrigation controller?

• A. To adjust the programming for different plant types
• B. To provide a global percentage adjustment for run times
• C. To set specific watering days
• D. To automatically determine watering needs

Answer: (B)

The primary function of seasonal adjustment in a conventional irrigation controller is to provide a global percentage adjustment for run times. This feature allows users to easily modify the watering schedule based on seasonal changes, such as increased temperatures or changing rainfall patterns. For instance, during hotter months, the seasonal adjustment can be set to increase the irrigation run times to ensure that plants receive adequate moisture. Conversely, in cooler months, the adjustment can reduce run times, preventing overwatering. This global adjustment is essential for efficient water use and helps maintain healthy landscapes while conserving water resources. The other options focus on specific functionalities that a conventional irrigation controller may offer, but they do not encapsulate the overall seasonal adjustment feature as effectively as a global percentage adjustment. For example, adjusting for different plant types relates more to specific programming rather than a seasonal overview, while setting watering days is about schedule management rather than seasonal responsiveness. Automatic determination of watering needs could relate to more advanced technology, such as smart controllers, which goes beyond the conventional irrigation setups that use seasonal adjustments.
