1.4.1. LEDs
These LEDs have a red LED chip and a green LED chip in the package and can show red, green, or amber
colors, steady or flashing.
NOTE: Smart Hub boot up time averages around 3 to 4 minutes.
Five indicators are located on the front of the Smart Hub enclosure
(near the top edge). One indicator location is reserved for future expan­
sion and has no icon and no current function. The other four locations
have icons depicting Smart Hub functions and are back-lit by LEDs.
Wi-Fi – Indicates the status of the internal Wi-Fi module and whether or not it is connected to the home Wi-Fi
network.
Thermostat – Indicates the status of the thermostat Mag-Mount and HD Display and whether or not the Smart
Hub can communicate with the HD Display.
HVAC – shows the status of the HVAC equipment in the home controlled by this Smart Hub, and whether or
not the Smart Hub can communicate with them.
ALERT – shows if there is a critical alert condition.
1.4.2. General Rules
S
Unlit indicators show there is no power to the Smart Hub or its software has suffered a critical initialization
error.
S
Steady amber indicators show Smart Hub boot up and self-check processes are in progress or have com­
pleted. Boot-up and self-checks normally complete rapidly, so amber indicators may appear only briefly
(except for the Wi-Fi indicator).
S
Flashing amber Wi-Fi indicator shows that the Wi-Fi module check is in progress. Steady amber Wi-Fi
indicator shows that the Wi-Fi module has passed its check but is not connected to the home Wi-Fi net­
work.
S
Flashing green indicators show acquisition and test of resources across wired interfaces to the Mag-
Mount / HD Display and to installed HVAC equipment
S
Steady green indicators show that the associated function is connected and operating normally.
S
Flashing red indicators shows a problem with the associated function.
S
Flashing red ALERT indicator shows that a critical alert condition exists. If one of the other indicators is
also flashing red, that is the likely source of the alert. If no other indicators are flashing red, the source
of the alert is not defined.
