I have 2 Aube timers that keep losing the program. These are brand new units. Has anyone else had an issue with them and had to replace them ? When I arrived on site last week it was flashing as if it had lost power but no power was lost on the one for the front yard. Another one on another property same thing. I have about 2 dozen of these installed but 2 failures out of 24 isnt acceptable to me. I reprogrammed it and it worked fine that night but the next day nada.
