The light has 3 plugs because 1 is for the lunar lighting, 1 is for the actinics, and 1 is for the 10K. You can figure out which is which by just attaching the plugs to a regular outlet and see which bulbs that they power. Then just mark it with a piece of tape. You cant control all 3 on the current timer that you have. When the yellow outlets are on, then the blue ones are off and have no power. You can attach the plug that powers the lunar lights into one of the blue outlets, and attach the plug that powers the actinic into the yellow outlet. Then set the timer for the time that you want the actincs to come on and shut off. When your actinics come on in the morning (start of day cycle) then your lunar LED
's will shut off. In the evening it's the reverse, actinics shut off and the LED
's come on.
The problem is that you want to have the 10K come on part of the way into your day cycle (will be on at the same time as the actinic) and shut off while the actinic is still running. That is going to require a seperate timer to plug the 10K into.
Coralife makes a powerstrip called a "dual power center" that actually has 2 timers, one at each end of the strip that will handle the 3-plug lights and that's what you need. This one has 3 different timed outlets, Black for LED
's, Blue for Actinic, and yellow for 10K.
Otherwise you either have to add another timing device, or manually switch the 10K lighting on and off.
Look at the "dual" controller at the above link and that will give you an idea of what you need.
