"aquabus version (53170):
The aquabus version of the farbwerk can be connected to an aquaero 5 or aquaero 6 controller. The aquaero can then be configured to control the outputs of the farbwerk or to transmit sensor data from the aquaero to the farbwerk to be processed by the farbwerk. Up to two farbwerk controllers can be connected to an aquaero 5/6 simultaneously. As a matter of course, this version can also be used as an USB device without aquabus connection."
