What is the main function of an irrigation controller?

The main function of an irrigation controller is to automatically open and close valves according to a set schedule. This allows for precise management of water application to landscapes, fields, or gardens by regulating when and how much water is delivered. The controller is programmed to operate based on time, weather conditions, and specific irrigation needs, ensuring that water is used efficiently and effectively. By managing the timing of water delivery, it helps in conserving water, promoting healthier plant growth, and minimizing waste.

Other functions, like measuring soil moisture, filtering contaminants, or increasing system pressure, are important in the context of an irrigation system but do not align with the primary purpose of the irrigation controller itself. These tasks may be handled by other components of the irrigation system or additional equipment. In this case, the controller's primary role is centered on scheduling and managing water flow rather than these other aspects.
