Rain Dial 6/9/12 Station Controller Dead After 10 Years: Reset or Replace

10-year-old controller. Stopped working last week. Buttons do nothing. Display shows "80" and "1112" upper right. New battery no change.

Short Lifespan, Try Reset

"My experience with these controllers is that they have a fairly short lifespan. You can try to reset it by removing the power supply and the battery for several minutes, then reconnect and reprogram. If this doesn't help, you probably need a new controller."

The cryptic display codes ("80", "1112") suggest microprocessor lockup. Power-cycle reset is the only user-level fix.
