Question
Hi, we have just relocated our controller & valves for our greenkeeper. On turning the controller on there was a buzzing noise coming from the actual valve. We narrowed it down to the actual plug in station control module, station #3. The controller itself still has power but am unable to change anything on the display or reset. Any Suggestions.

Answer
Hey Dave, I would suggest taking the backup battery out of the controller, and then power down the controller for about 1 minute. Then with the battery "not" connected, power the unit back up and see if you get a better display that you can re-set. If not, then take the unit in, and it probably needs a ne micro-processor. Good luck and have a great day.
