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 always free of voltage.
