Help with programming Zetlight?

[Atf22]

Hey guys, i bought this Zetlight from a reefer on here and i love the light! Super bright, looks sleek and overall really well done. But i don't know how to program it. I've got the time set and when it should turn on and everything, but it's not doing it. Can anyone help me out with this? First time having a programmable light so odds are i just don't know what i'm doing! Thanks
