How many L ports does the GHL Aquarium fan controller use?

[Harry_Fish]

I'm considering adding the GHL Aquarium fan controller unit
but the question I have is how many L ports does it use?

I would Assume only 1 but just want to make sure.

Also is it jumper selectable as to the port?

Thank you.

Harry, it only uses one L port. I don't know about the jumper, we may have to wait for Michael or Mattias to jump in on this.

Which fan did you get? 3,4 or 5?

I want to get one, I have to see which one will fit right, I want it to go across my sump 18" so it blows on the water flowing down my baffle. Where the water is nice and thin.

No fan yet, still thinking on it.
