The EZ Pro Jr. 8300 Series controller has a 5-second delay before starting a manual or timed operation. If the % WATER BUDGET is set to 110% or greater, the system splits the run time in half to reduce runoff, which may create a pause between the two halves. This brief pause could appear as the system shutting down temporarily.
