Question:
I have a toy hauler and I replaced the tanks sensor system with the Seelevel II 709-4. It is working correctly. I actually have 2 black tanks on in the garage. The system can handle up to 7 tanks. Can I wire in a send black tank to the existing system or will I need a different display?

Hey Larry. The SeeLeveL RV Holding Tank Monitor item # SE84VR can only monitor four tanks which is why there's only buttons for Fresh, Gray, Black, and Galley tanks. The Fresh, Black, and Galley tanks can have two sensors, or senders, installed inside them, which I am guessing is where you got seven from.
Unless you have an extra spot open you'll need to purchase another display like item # SE97VR and sensor item # SE27VR for your second black tank.
