3 floats

[thoughtiknew]

Is there any way using the ra+ to connect 3 floats without an expansion module I would like to have a low ato high ato and high shipmate currently my actinic channel is vacant can it be used as an input?

I have my sump high and low wired in parallel to ato high. If either go off i disable return and skimmer. My ato low is connected to an avast marine skimmate locker. I also treat the two switches as a single standardato which i use during my automated water change. My actual ato is gravity so it's always spot on.
