The display itself will give you access to most of the basic settings of the controller. Have you tried to access the menus of the 850c display? If not, I would search for a user manual for that display to navigate through the menus.
yes you program your controller with proper LVC setting, Amps for the motor, wheel size, couple other settings. links to guides here https://www.johnnynerdout.com/forum/general-ebike-forum/victory-best-performance-e-mtn-bike-best-decision-ever
