Dimmable Ballast Q

[Delphinus]

OK think I found the info. On page 63 of the Comprehensive Manual (first link at the address above) I found this:

Programming for dimmable lights is a little different than regular lights or even variable voltage pumps. For
starters, you use two outlets for each ballast – an EB8 outlet for the 120vac power and a variable speed outlet to
control the dimming. This is true whether you have VHO or LED.

Guess it depends on the ballast, maybe 0 on the input doesn't shut the ballast completely off so you want to cut the power at the plug as well.. Weird because I don't think you need to do that for controllable pumps..
