the best feature of the VarioS controller is a 0-10v input which will
allow a 3rd party controller such as Neptune System’s APEX or Reef Angel
to take over the pump and tell it what to do. In this mode, the new VarioS
controller becomes an interface between the system controller and the pump
allowing you to create intricate programs using your system controller
native language. This is unprecedented controllability on a skimmer or
water pump. In essence, you can use your system controller as your DC pump
controller!
