a) If there are display errors on the webpage such as header errors and wrong icon placements, use the browser's
mandatory refresh function to refresh the page (such as "Shift+F5" for the Chrome browser).
2.2 Appendix 2: Wired Controller Group
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.
Condition
IDUs in Wired Controller Group
"Control” Icon
View
When one or more IDUs are offline in the wired controller group, the wired controller group icon will display an
offline status. When there are errors in one or more IDUs in the wired controller group, the wired controller group
icon will display an error status, and the error code will be the error code in the IDU with the smallest address.
When the wired controller group is normal, the wired controller group icon will show the operating state of the
smallest IDU.
