How to hook up a low water float shutoff

[kobelka]

Hi,
I have a neptune jr controller and would like to hook up a float switch to turn the pump off should the water level ever drop too low in the return compartment. I have no idea? Laymans terms please, from the plug in to the float and all parts between.
Thanks
Dave

Do you have a breakout box? Without the breakout box, it will be difficult.

Sorry not sure what a breakout box is?

If you have the serial plug for the bottom of the unit I think it is pins 1&2 if you check the neptune site the manual is there

Instructions on how to wire a switch are on page 23 of your manual. http://www.neptunesys.com/images/dow...Serial_web.pdf
