Estimating the term…
The present invention provides an irrigation control system in which a device (irrigation scheduler) automatically modifies irrigation schedules of installed irrigation controllers to affect irrigating of the landscape based on the water requirements of the landscape plants and comprises: providing an irrigation controller programmed to execute irrigations on watering days by closing an electrical circuit connecting the controller and at least one irrigation valve; providing an irrigation scheduler programmed to execute irrigations on substantially equivalent watering days as the irrigation controller; and the irrigation scheduler selectively interrupting the electrical circuit to control the execution of irrigations on watering days. Preferably the microprocessor uses either an ETo value or weather data used in calculating the ETo value to at least partially derive the improved irrigation schedule.
A method of controlling irrigation, comprising:
An irrigation scheduler that cooperates with a separate irrigation controller having an electrical circuit that extends from the controller to an irrigation valve, the irrigation scheduler programmed to:
An irrigation scheduler that cooperates with a distinct irrigation controller having an electrical circuit that extends from the controller to an irrigation valve, the irrigation scheduler programmed to:
