What does the feature of multiple programming on automatic controllers allow?

The feature of multiple programming on automatic controllers allows for more than one watering schedule or program. This is particularly beneficial in various landscaping scenarios where different types of plants or zones may require different amounts of water based on their specific needs. For example, a garden area with drought-resistant plants might need less frequent watering compared to a lawn that requires consistent moisture.

By having multiple programs, users can customize watering times, durations, and frequencies for different areas of their irrigation system without having to manually adjust settings each time. This not only promotes water conservation but also enhances plant health and growth by ensuring that each area receives the appropriate amount of water tailored to its individual needs.

Other features like changing the water source, automatic adjustment of water pressure, or remote access to irrigation settings do not directly pertain to the ability to create diverse watering schedules within one system, which is the core function being highlighted by the multiple programming feature.
