Question
I have a Hunter EC four station indoor control panel that worked perfectly last summer but now won't cooperate.  I can't get the time to update no matter what.  I've disconnected the power and reset the system several times using the reset button without any luck.  When putting the system to update the time, it only allows me to update the hours and not the minutes or days.  I've tested the arrow button that allows for updating functions in other settings and it works fine, so it's not the button.  I've tried to be smarter than the controller by just running off the display time, but that won't work either because the days won't update.  Where do I go from here???  Any help will be greatly appreciated, thanks.

Answer
Sounds like youve tried everything I would have tried.  You might make an attempt to clean the circuit board by gently spraying it with one of those canned air devices, and gently brushing it with a soft brush.  Otherwise, I'd have to say the controller should be replaced.
