(I can't seem to open a ticket using Firefox so I'm posting this here)

I purchased a third PropellerBreeze 3-6 and installed it. However, it pushes almost no air, even when 10v is sent to it via the Profilux 4 (connected to an Expansion Box 2) compared to the other PropellerBreeze units.

The only difference in the installation of this one compared to the other two is that it is farther away so I had to use a longer RJ11 cable that I purchased elsewhere. I can't test it with the cable that came with the controller without some difficulty (cables are in place and can't move the expansion box closer...).

If I unplug the RJ11 cable from the controller, the fans stop. However, if I set the L port to "Always off" instead of "Temperature 1" and save the settings, the fans continue to spin...

I have one 0-10v expansion card in the Profilux 4 so the 0-10v interfaces on the Profilux go from 1 to 10. Can someone confirm that the L3/4 port on the Expansion Box 2 corresponds to 0-10v interface 13, without using a Y splitter?

Thanks!
