I have just purchased an Elite 400 and some of the modes need to be set using the app. I don’t have a cell phone so where does that leave me with setting them? Can it be done manually or not? One such mode which seems to be important is the Grid Self-Adaption Mode that protects from unstable generator or grid power, etc.? What is the alternative if I can’t activate this setting? Does it just leave the unit and connected devices unprotected?
