You are using the correct procedure - right ? Assuming that you are starting with two known-full tanks, start by SLOWLY opening one of the tank valves. (doesn't matter which one) then turn the indicator knob so that the arrow or indicator colored dot is pointing at that tank. Then SLOWLY open the valve of the other tank. The valves on both tanks must be completely open for the auto changeover valve to operate. The indicator in the center of the knob will show green and slowly change to orange or red as the propane in that tank is used up. When the color changes COMPLETELY from green to orange (or red) , that means that the auto changeover valve has switched to the back-up tank. Then switch the indicator knob arrow to point to the back-up tank , the indicator in center of the knob will change to green. Remove the original tank, get it re-filled and re-mounted and then SLOWLY open the valve. Then repeat this procedure as required. If your tanks do not change over properly after using this procedure, then you likely have a defective auto changeover valve.
The auto changeover regulator at the beginning of this short video illustrates the type that I am referring to.
