BIO-A Aerobic Control Panel Applications

To make a decision on which panel will work best for your particular system, you need to figure out what the components are of your system. Every aerobic system will have an air pump, that is a given. Some systems but not all will have a submersible pump to remove the water from the system sending it either to a secondary treatment system, or commonly a drip irrigation or spray irrigation system. The type of system you have will determine which control panel functions you will need. See these options discussed further below.


The BIO-A-AV double light control panel works best on aerobic systems that include a submersible pump and a spray irrigation or sprinkler system. This panel includes three breakers for the alarm circuit, air pump circuit, and submersible pump circuit. It includes separate alarms for both high water and air pump failure. The high water alarm operates from a float switch in the tank, while the air pump failure alarm uses a pressure switch connected to the pump via a 1/8’’ airline. This panel also includes a timer which allows you to control what segments of the day you wish to have the submersible pump come on (as little as 15 minute intervals).
