Error codes for Indoor and Outdoor Units
This list contains all possible values shown in KNX Object for “Error Code” for each indoor unit and outdoor unit.
It must be taken into account that Outdoor Units are only able to reflect a single error for each indoor / outdoor unit in
the system. Thus, a unit having two or more active errors from that list will only report a single error code
– the one of
the first error that has been detected.
