The sequence
Put the dial or the menu on the current date and time first. A program that thinks it is a different day will water on the wrong morning. Then turn off every start time you are not using. Extra start times left over from a nursery program are why a yard runs three times before noon.

If the clock will not hold the time after a storm, call 346-642-6161. That is often a battery, a transformer, or a short in the field, and those are different parts.
