One of the most common reasons for a sprinkler system to water intermittently and show the word DELAY on the display is because a delay time was programmed into the controller. This video will show you how to get rid of this delay
The Pro-C controller is equipped with a delay between stations function. This feature allows the user to select a time delay between the end of one station run time and the start of another station's run time. The delay can be as short as a one second or up to 4 hours. The delay is a convenient feature when working with slow closing valves or slow well water recovery.
NOTE: The Master Valve/Pump Start circuit will operate during the first 15 seconds of any programmed delay to aid in the closing of the valve and to avoid unnecessary cycling of the pump.
