Standby In this operating mode, all internal functions are turned off. Frost protection remains active and
a blocking protection for the pump is guaranteed.
All controllers integrated in the RoCon-system via the CAN bus are also switched at a higher
level to the operating mode when this setting is selected.
Outputs are not free of voltage always.
