Hi, i currently have a Profilux plus II, with a 4 head doser, and 2 old style powerbars connected.
If I was to buy a profilux 3 second hand or a profilux 4, could I use the expansion cards for the temperature and pH I have for the Profilux plus II, the 4 head doser and the old style powerbars with the newer controller?

Thanks, Di
