A related question:
I have two 0-10v controllable return pumps (Red Dragon 100s) and at the moment I have each one on its own stream group so that I can control them individually (permanent, no wave and constant speed at 50%). I tried having them on the same group on the permanent setting but that didn't allow separate control.
But this takes up two of the four stream groups that are showing on my P4. A third stream group is controlling my six Tunze stream pumps and the fourth will be used to control my skimmer pump speed (BK SM 200). That means no more stream groups available?
Is there a way to have them on the same group but control them separately? For example, if one pump dies, I would need to increase the other pump to 100%...
Thanks!
