Help with airlift system

[Rockettlauncher]

I just purchased a truck with an Airlift/Lance system with two cab controllers. The truck has rear airbags, and 4 adjustable Rancho 9000 shocks. One controller is black, has three buttons and two LED readouts on the right side on top of each other. I did see a nother diplay next to the button on the left . That button also has a small red light that comes on one in a while. The displays all currently read 0. The bottom controller has an LCD display with /- buttons on the left and right sides. It seems to display the airbag pressures, left and right, but when I air them down with the - buttons they seem to air up again after a while. Anyone know how this sysems works? I have tried various button combos but no joy. Lance never responded to my phone calls and Airlift is still looking for instructions. This is a 2005-2006 system.
