Hi Luke,
I know what you mean mate.... Those modes, Sunny Hot ,Sunny warm, Cloudy dont exist anymore with the new Advance Controller.( they were factory preset modes on the ALC version)
They are now replaced by P1 (Programable)P2 and P2+lightning.
S1, S2, S3 are all Static modes, in other words they dont ramp up or down.
The beauty of the new P1 and P2 etc is that you can now program your curve/ramping to what ever you like for each segment of the day.
This will enable you to put in different values too, and therefore you could get a cooler/warmer colour temperature or you could put in a dimmer value and thus simulate a cloud passing.
Studys have shown that clouds passing or even different wave amplitude can stimulate zooxanthellae reproduction.
