kenargo:
Can you provide some examples of what the VDM can do with the AI lights that the AI controller cannot do...other than syncronize the lights with other events (not that you cannot do that, as long as you know the timing of the other events).
Thanks
Lets start with profiles; which is the most confusion part of the programming. A profile is a set or parameters and include ramp time (up or down); initial brightness, start of ramp and ending brightness, after the ramp is complete.
The Apex has 16 profiles that you can activate at any time you want and on any condition you want; including based on the day of the week.
Next is weather mode; which is just a profile of a different type. At 1st I thought I wouldn't use it (felt the lightning was just a little hoakie) but I now use the cloud mode to enable a random brightness during the daytime hours an the SPSs so far seams to respond well. Lightning; I have a theory but I haven't done the testing except for short times; I theorize that a lightning storm every so often might make light sensative critters less sensative to people walking by the tank; but again I haven't tested it so I'd need to get back to yo uwith results later.
The AI controller is fine and yes, it is very easy to dial in the colors now that they have 3-channel but I added the AI using a PAR meter and am glad to report that I might be one of the few persons that didn't burn out their SPS when making the switch; based on many persons I spoke with who had bleached out corals. I set my colors using a profile; I created 1 with no ramp time, assigned it to the Blue and another to the white and plugged in values while sitting at my PC. I agree the dial on the AI controller would have been more simple but I wen't the other route.
A profile can also be set for moon in which case you can control lunar cycle using the Apex season tables.
One thing I did do is to connect the AI power supplies into an EB8 outlet and the outlet turns on when my daytime profiles are active or moon profile is active so I get a tiny savings by not having power to the fixture when it isn't needed; the AI controller needs the lights all powered all the time but as I said; minor savings especially considering the near $60 per month savings moving from PC + MHD to 6 LED units!
Really; the key is understanding the profiles; once you get them down it's really 'the skys the limit' to what you can do.
You can see my program on my webpage if you are interested. I have a morning and evening ramp that is separate then the mid-day ramp; giving a pause in the ramp. Required, no; but I like the affect.
Feel free to ask anything you want and I'll try to answeras best I can. I also placed a link to a strm example on my website complete with a YouTube link; a novelty for now but as I mentioned I am using cloud mode.
