Replacing a Main Hub
You must record the system configuration settings from the old Main Hub’s memory
before replacing the unit (refer to Step 1 below). You will program the new Main Hub
with this information. If the Main Hub is programmed incorrectly, the system will not
work. If the Main Hub is not functioning, get the configuration settings from the
As-Built Document that was created as part of the original installation.
