If you want to keep it simple the Apex has what I call macros for programming, such as one for lights, one for pumps , ect, ect all you do is just fill in the varriable such as time you want the light to come on and off. Very easy, when you want more advance features you can switch to the advance mode. If you are interested I suggest downloading the New User Manual that is stickied to the top of the Neptune support forum on this site. Very well written and easy to understand.
Hope that helps and did not confuse.
