Profilux II plus aquarium controller

[bourbon]

ok niloc16 so you mention that you are waiting for a y connector to connect the fans to the L1 port - so does this mean that you have all of your L ports used up? because they ports are labelled L1/L2 I'm assuming that you can connect 2 devices per port but need a y connector. Is this right.

I also remember reading that if you connect 2 tunzes to L1/L2 that you can't operate them independently - you have to use L1/L3 which takes up 2 ports. I'm concerned about the amount of L ports I will need. So by similar logic I'm assuming that if you have more than 1 LED you will have the same problem - i.e. use L1/L2 but not control them independently or use L1/L3.

Can you comment on these ports?

if my lighting had dimmable ballasts how does the profilux dim them - via a ramp down on voltage through the electric plug on the ballast or a special connection between say a L port and the light itself?

Thanks
