Richdell 500 PR Series Hybrid Controller


I am new to sprinkler systems and recently have started using a 500 PR Series controller with 4 zones, (that came with my place). I followed the instructions and set the date and time and then set the zone start times.

What occurs is that the zone watering cycle starts but then it keeps repeating. It keeps repeating until I have to cancel the session by pressing the clear/rain button. I have tried to set a 5 to 10 minute delay between zone watering times, but that doesn't work either. I have disconnected the unit, and unplugged the battery and re set the unit a couple of times with no success.

Any recommendations?

Thank you.

Only one start time is required. When a controller is programmed with more than one start time, it will cycle again and again.
