Abstract: Disclosed herein are methods and systems for improving performance of sprinkler control systems using aggregations of flow controllers. As an example, to facilitate control of multiple controllers, a system may generate a virtual flow controller by aggregating the two or more flow controllers. A schedule for the virtual controller is set or received and then translated into schedules for the aggregated controllers. In another example, schedules may be set for individual watering zones, which are then translated into watering schedules for flow controllers corresponding to the zones. The system then transmits these schedules to a respective flow controller, which then carries out an irrigation routine according to the schedule.

Abstract: A control system includes equipment and a controller. The equipment produces a resource by executing a first process when in a first state, and produces the resource by executing a second process when in a second state. The controller calculates a minimum second state operating time based on estimated cost savings resulting from operating in the second state relative to the first state. The minimum second state operating time is a minimum time amount that the equipment must operate in the second state for the estimated cost savings to offset cost of transitioning into the second state. The controller predicts whether the second process will be available for the minimum second state operating time during future time steps. The controller transitions the equipment from the first state to the second state in response to predicting that the second process will be available for the minimum second operating state time.
