Pin2 Profilux--->Pin1 + connector
Pin3 Profilux--->Pin3 - connector

Pin2 Profilux, if you want to use L1,L3,L5 etc.
Pin5 Profilux, if you want to use L2,L4,L6 etc.
But please use an RJ12 connector, and use the right cable for RJ12 6/6 wiring.
Then you have to assign the interfaces under 1-10V settings to the pumps
