Question on sensors

[doggydoc]

I have a P3 and I am trying to set up a sensor to stop the main pump in case water levels rises inside the overflow box.
What is the easiest configuration to achieve so, and what equipment do I need?
Sorry for the questions but I am a newbie and trying to use the P3 to the fullest!!!
Thanks

1 x optical sensor and bracket assy

set your main flow pump to water level 1

set the level sensor 1 accordingly

Put sensor in overflow box

Ok. Trying to place the order, want to do it correctly. Do I need the Profilux Water Level Sensor Bar Assy and Profilux Optical Level Fastner?
