If you simply want to start over or if your controller is not responding to your commands, you can reset the X2 controller easily. This will return the controller back to factory defaults and erases watering schedule and settings.
Turn the dial to the RUN position. Remove the lower wiring compartment door by pushing straight down. More info here.
Press and hold the program button.
Press and release the RESET button located inside the lower wiring compartment. The button will require the use of a small pointed tool; e.g. paper clip.
When the display reads the controller station count; (e.g. 14) then DONE, release the PRG button.
The display should now read 12:00 am and set back to factory defaults.
