first you need to locate the AGS control module. On my coach in is located on the ceiling of the same compartment where the inverter is mounted. On the control module there are a few settings that can be adjusted with a small flat tip screwdriver.
Here is the data sheet which shows a picture of the module and a brief explanation. My coach has the AGS-S and not the network version (AGS-N).

Hope this helps.
