Reef Octopus VarioS-4S Controllable DC Skimmer Pump

Reef Octopus VarioS-4S Controllable DC Skimmer Pump has a tidy, efficient and upgrade skimmer for many skimmer setups. It is quite, flexible and
automatable. The vast majority of VarioS-4S Controllable DC Skimmer Pump uses alternating current (AC) the VarioS skimmer pump boasts several key advantages over traditional AC pumps like greater energy efficiency and safer low voltage operation. In this skimmer pumps you can control the rotational speed of the motor, and that’s why it control air electronically and also control the water flow rates into the skimmer.

• REFINED CONTROL:

In addition to allowing the pump to run at 5 different speeds,

A float switch connection, which allows you to connect a float switch (included in the box) to the controller.
waste collector is full or shut off your water pump when your sump water has reached a high or low level. In
all, you don’t need another module or controller to add a float switch to your system.

Two different pause/feed modes that will shut off the pump for either 15 or 60 minute intervals. These come
handy when you are feeding the tank or conducting regular maintenance such as a water change.

And 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 pump.
In essence, you can use your system controller as your DC pump controller!

The VarioS pump features a true slow startup where the pump slowly ramps up from zero RPM to the full
preset speed over a period of approximately 10 seconds. The volute can rotate to change the pump’s output
orientation in 90 degree intervals, meaning users can output water vertically (up or down) as well as horizontally.
