Methods and systems of controlling the operation of a pump according to a pump operation schedule are described. In one constructions, a pump controller enters a programming mode and monitors a number of inputs received through a user interface while in the programming mode. The programming mode is then exited and a delay time is defined equal to one hour for each input received through the user interface while in the programming mode. A stored pump operation schedule is accessed and operation of the pump is initiated according to the pump operation schedule after a period of time equal to the delay time has elapsed since exiting the programming mode. Operation of the pump is again initiated according to the accessed pump operation schedule every twenty-four hours since the pump operation schedule was last initiated.
