I am looking to setup a dual loop with the D5 Aquacomputer USB Aquabus pumps. If I chain the Poweradjust 2 Ultra to the Aquaero 5 XT (That I know how to do), on the two free Aquabus interfaces that are on the Poweradjust 2 Ultra can I install the pump Aquabus cable and still use the fan headers to control for instance the radiator fans?
The Poweradjust has two Aquabus ports and can be daisy chained together, but MPS devices only have one so they need to be used with splitter cables. Not sure what you mean by two free aquabus on the poweradjust 2 ultra? ... one is input / one is output to the next device.
So you would have the aquabus high port on the AQ5 connected to the fist aquabus port on the poweradjust, then the second aquabus port to a splitter cable that connects to both of the aquabus ports on the two D5 USB's
