Question
Thank you in advance for helping!  
My Rainbird works fine, except the only way I can turn the unit off (to skip a day during rainy times) is to set the percentage % setting to zero.  Otherwise, if I move the lever to off, the unit will continue to cycle like a regular day.  What can I do?  Again.. THANKS!

Answer
Have you pulled the back up battery and unplugged the controller for 30 seconds? Seems to be an issue with the processor.  That model has been discontinued for awhile now so I'm not sure about availability of any internal parts. You may need to call the Rain Bird number on the controller if you are thinking about repairing the controller.  I have only seen a small fraction of those controllers still active in the field.
