I have 3 Koralya power heads 2xtype 3 1xType 4 controlled by profilux3ex
The pumps are connected to a digital powerbar.
Pumps 1&2 are in group 1 and pump 3 in group 3.

Group 1 is programmed to random function. Until recently the pumps turned on/off randomly (as expected) but since I have updated to the latest firmware pump 1 is constantly on and pump 2 is always off.

Any ideas what is wrong?
