For the new units, certain wired controllers support the access of multiple IDUs where these IDUs will then form a "wired
controller group". In CCM-270A/WS, these IDUs will be treated as a single virtual IDU, and in the icon view in "Control" the
wired controller group of IDUs will have its own icon. The name of the wired controller group is the same as the name of
the smallest IDU.
Note: Refer to the relevant manuals on wired controllers and indoor units for specific information on how to set the address of the wires controller group
