Oh, just to add to Ian's post so people don't get confused, the 4 pump unit is an add on to the 3 pump master unit. You need at least one master unit and then can add two more of the slave units if you want for a total of 11 pumps.
Though you can run a 4 pump unit using a aquarium controller (doesn't need just to be the T01), this true?
