Coralife aqualight digital power center timer

[ITS_JUST_ME]

hello, i am trying to help a co-worker with his coralife aqualight digital power center timer. he has the type with the digital clock on the top with day, hour, min, clk, mode, and prg buttons as well. i have followed the directions in the users manual and set 7 time cycles to turn the daylight outlets on @ 7:00 am and turn off the daylight outlets @ 8:00 pm all week long (sunday - saturday) i am confused what to set the mode setting to. when i set the mode to automatic, the night lights turn on (even though it is not after 8:00 pm when the day outlets get turned off) the day outlets come on when i set the mode to "on". which mode shall i set the unit to so the day outlets will be on from 7:00 am - 8:00 pm sun-sat as i have set all 7 time cycles to, and turn on the night outlets after 8:00 pm when the day outlets are turned off? i hope this has not confused you too much! i tried to explain the situation as best as i could! thank you in advance for your help. have a nice day
