BMS as control with digital predefined load via CAN bus.
The LMV51... system is connected to a BMS via the AZL51... and an external e-bus
interface.
The BMS contains the controller and transmits the load (manipulated variable) and the
heat demand signal to the LMV51... system.
In this operating mode, the load controller inside the LMV51... is not required.
