This means that the maximum of the central control address equals the number of connected
indoor units.
However, if an address is omitted, the maximum of the central control address differs from the
number of connected indoor units. In this case, set the maximum of the central control address
according to the table below.
Note:
The system works normally when the set value is larger than the maximum.
However, it will result in communication loss.
