We have been getting a lot of rain here in Nebraska for the last 6 to 8 weeks. About 5 weeks ago, I turned my controller to the "off" setting as there is no need to water grass that is getting plenty of rain.

I tried turning the controller back to the on position and the only thing on the display is the letter A and the numbers 337 no matter what function I have the dial set to. The display never changes.

I did unplug the unit from power and plugged it back in but the 337 always comes back.

Any ideas as to what is wrong with it?

Thanks in advance!
