Bus Activity LEDs. This is a set of green/red LEDs. When the bus is running normally, both will
be blinking. If only one is blinking (red), then it means that the bus is not connected to the Zone
Control Modules.
iQ Bus Activity/Configuration LEDs. In normal operation, this set of green/red LEDs blinking,
indicates that the Airzone Controller is communicating with the iQ Controller. During the process
of saving the configuration setup, the LEDs will be ON while receiving information from the Zone
Control modules, and will return to OFF once the configuration is saved.
