Question about level control with 2 sensors

Hello,
I have a Profilux II Plus and I'm looking to install a level sensor in my sump to turn off the return pump in case of a water shortage. Additionally, I want to place a second sensor in my aquarium that will also shut off the return pump if the overflow gets clogged, preventing water from the reserve tank from flowing into the sump.

Could you please guide me on how to program the Profilux level control to accomplish this? Any helpful information would be greatly appreciated.
