I also have the AC D5 pump installed with Aquabus, and it works just fine.
Go to AS2012, click on Aquaero 5 tab, then down tothe Outputs tab, click again, then on rhight side, scroll to bottom of page, find "MPS" section. It will list "mps D5-1" through 4. Click on the ones showing a percentage above 0.0 and to the right of that is where you can change the name of the pump and set minimum and maximum pump power.
You can also set up a controller in the Controller setion and set the mps D5-1 or-2 as outputs.
Hope this helps.
