8. Error codes for Indoor and Outdoor Units

This list contains all possible values shown in Modbus register 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.
Error Description
