Pump Stop and Start -analog threshold trigger

I need to start and stop a pump based on an analog input via a transducer. I have used the analog threshold trigger for the start and stop values. It seems this works that any time the vaule is in this range the output is triggered.

This application is for keeping pressure in a domestic water system. I want an on signal when the pressure drops to 40 psi then the off signal at 60psi. Not while the pressure is dropping down thru the range. The analog threshold trigger gives an on when the pressure is any where in the range of 40-60. I also want to keep it simple so the pressures can be changed from the LOGO! screen.

any suggestions?
