Answer:
Step-by-step explanation:There are two possible causes to take into account while troubleshooting an irrigation zone that is not turning on at the scheduled run time.
Timer or Controller Issue: The timer or controller that is in charge of turning on the irrigation zone is the first likely culprit. Verify the programming of the timer or controller and that the run time for the impacted zone is set correctly. Additionally, make that the timer or controller is powered on and operating normally. A programming error, a bad connection, or a broken part inside the controller or timer could all be to blame.
