Auto Top Off

[monkiboy]

Which option did you setup your JBJ ATO ? Mode B that has both sensors in the sump or Mode A that only has one sensor in the sump ?

both in the sump. i use a BRS ATO pump so running dry isn't a problem. Edited April 10, 2013 by monkiboy

So the 2nd sensor for the JBJ can either

 

1) be used to stop the pump in case the first sensor screws up and keeps the pump running (max level), therefore preventing water on the floor

or

2) be used as a sensor in your top off resevoir to stop the pump in case your out of water (min level), preventing a burned out pump

 

Is this correct?

 

Just comparing this to the tunze nano, which in scenerio 1, uses a timer instead.

 

Thanks.

That's what I expect. Maybe someone with a JBJ ato with this "Mode B" -> 1) can confirm it. "Mode A" -> 2)
