Why does the HCC 2.x.x.1 not reset a change from main to backup pump after the end of the manual operation in "double pump mode"?

If no sensors are used for error monitoring, it is not guaranteed that the device will permanently change the main pump if an error occurs. In order to change the pump permanently and user-friendly via the manual operation, for example to maintain the main pump, the change from main to backup pump must remain active even after the manual operation.
