Nano Ballast

My Coralife timer did that to with my MH ballast.. before you go to bed, switch it from ON to AUTO and it should work when the new signal for ON comes on. A bit weird, but otherwise it wouldnt work the first cycle if I started it in the AUTO (when lights were supposed to be on).

Check also if you have the correct time and sequence times.. I thought my timer was broken at first, but its working well now
