So just an update on my fixture. Yesterday I got home from work to find a new bulb at my door step. Unplugged the fixture , did the bulb swap . When I plugged it back in the display showed ATI and nothing else. I unplugged for a few than plugged back in and across the display was a solid bar . Unplugged it a couple of times and the same thing showed on the screen. I waited maybe an hour, of course freaking out that now I don't have a light over my tank and plugged it back in and it finally let me adjust the clock and the lights came on. When I adjusted the clock the display showed that the lights were on at 187% yes 187% , so I adjust everything down and had it set to the normal settings . Meanwhile (back at the bat cave) during this time I had emailed ATI about my situation and Keith Smith got back to me this exact same night ...which is amazing , thank you Keith. Said I probably needed a new timer and I should try to set the system back to default by holding all the buttons down for 7-8 sec. and then reset the fan , gave me a link to you tube to show me how. I didn't want to mess with it at that time because it was working . When I got up 5 am this morning the lights were on full blast and the settings were all messed up so I just unplugged the unit and will deal with it when I get home today.
