Help programming RKE myReef float switch

[gregzz4]

So, to clarify for the next poor sap reading this ....
When programming in myReef, you need to change the FUNCTION of the unit plugged into the PC4.
In my case, it is a pump and I had originally set it to Pump
I changed it to Switch, and then I was able to set the On when / Off when
Hope this helps someone else
