Low battery protection
This mode is particularly well suited to the use of auxiliary batteries, which are not relevant for starting the vehicle.
Medium battery protection
This mode is suitable for the vast majority of situations. It is particularly well suited for when a modern starter battery is in place.
High battery protection
This mode is suitable if, for example, older car batteries are used, which may be relevant for starting the vehicle.
