Irrigation/error code 2


I have a Nelson smartzone EZ which has worked well for years, this year when I swithced it on a message error2 comes up on the screen and I cannot program it although the system works ok on manual/test. I have changed battery and turned power off for a minute , but no good. please do you have any ideas? thanks

The owner's manual states "Er2" indicates the controller has more then 24hrs of runtime programed.  Solution;  Review your total run times on all programs and correct -OR- Press reset and select + at the same time to return to factory default settings.

I am able to answer any questions related to lawn irrigation systems and backflow devices. But pumps are not my speciality since they are not common in my area. Most of my product experience is in Hunter, Rainbird and Irritrol components.
