With a version 3 controller you are able to use tweo pumps with one Aquaero cause of the ID-jumper. You are able to change the LEDs and the engine smoothness ought to be a little bit improved.
A version 3 controller can not be overclocked with the old jumper trick
Every controller version should work without problems. To use all features you need at least a controller with firmware 1.05. Below you are not able to adjust the pump but it will work.
And for theseeker: something is strange, you asked him if his pump looks exactly like the picture which I posted. That is a version 3 controller but the picture of his Aquaero says firmware 1.07 for the pump which is a version 2 controller.
