Want to use two External Level sensors with one controller..

[keener]

OOPS! I posted this same question in the German section, can someone delete that one, thanks!

--
Do I need the level sensor Y-splitter for this? Is the connection the same as the other level sensors (optical and float switch) ?.

If this works I assume I just plug the two External Level Sensors into the y-splitter and then the y-splitter into the level1&2 socket on my profilux III?

Oh, and I would also like to know if it is possible to have 3 level sensors? The two external level sensors I plan to use for an automatic water change system and if possible, I'd like to use the third level sensor for an auto top off. Yes I know I can reuse one of the two level sensors for ATO but I don't want to do that. I would like to have a separate one in a separate tank.

edit: I just figured out that the EX kit has a third level sensor socket, so that should work.
Thanks!
