Probably a really dumb question. I have a two LiFEPO4 batteries in parallel in an TT. There is no second battery system. I am trying to run the setup on the BMV-712 unit and follow the manual. I enter the battery capacity in step 1.1, However, step 1.2 is not needed as I do not have a separate starting battery, I do not need a midpoint monitoring and I have no temp sensor. Yet the setup on the 712 display (not through the app) keeps insisitng about the info for aux imput by cycling into step 1.2 after I setup the battery cap in step 1.1. With only three options and no skip option displaying on the LCD screen for te 712. How do I ignore.disable this step? Thank you.
