Help programming RKE myReef float switch

[gregzz4]

So I'm feeling all kinda short bus right now

I've tried to set up a switch to kill my return pump if the level rises too high in the overflow box.
Problem is, whenever I try to program it in myReef, I don't get an option for Trip, only Trigger
I can't find where to set Trip On/Off Open/Closed

Hope someone can help
Thanks
