Profilux II plus aquarium controller

"i'm setting it up right now like that but the controller only recognizes up to 19 sockets" - i have no idea what you mean.

You can program the START NUMBERING for a digital powerbar. If you program "1" as a start number the powerbar will have sockets 1,2,3,4,5,6 (this is default).
If you program "2" as a start number -> sockets 2,3,4,5,6,7
and so on until 19
if you program "19" as a start number the powerbar will have sockets 19,20,21,22,23,24
Where do we loose here sockets?!?

"the outlets are identical to 1st digital bar and i cannot control them different."
-> you must program different start numbers for them. See manual "Digital powerbars"
