Lennox iComfort S30 Smart Thermostat Operating, Troubleshooting And Technical Cheat Sheet page 5

1.4.3. Center Push Button Indicators
The center push button has a RGB (red-green-blue) LED backlight that indicates the Lennox-managed local
network communication status of the Smart Hub, and if the Smart Hub is transferring a software image from a
flash drive plugged into the USB port. While this LED indicator can show any color, it is currently limited to am­
ber, green, or blue.
When the Smart Hub is in a normal steady state -- when the Smart Hub is in normal day-to-day operation -- the
center push button backlight shows:
S
Steady blue when there is only one Smart Hub in the home and it is not connected to a mobile device
running a iComfort
S
Steady blue when there is more than one Smart Hub in the home, but this Smart Hub is not connected
to any other Smart Hub.
S
Steady blue when the Smart Hub is connected to another Smart Hub in the home through a Lennox-man­
aged local network.
During various Smart Hub transient states -- when the Smart Hub is engaged in a special task that should
complete soon -- the center push button backlight shows:
S
Steady amber (briefly) while the Smart Hub conducts self tests and boots up.
S
Flashing amber while software or firmware updates for an iComfort
nected field-upgradable HVAC asset is being transferred from files on a flash drive plugged into the Smart
Hub USB port.
S
Steady blue while the Smart Hub conducts checks on its internal Wi-Fi module and remote HVAC assets.
(icon indicators show progress.)
S
Flashing green when the Smart Hub is attempting a Lennox-managed local network connection with an­
other Smart Hub in the home or with a mobile device running the iComfort
application.
S
Steady green when the Smart Hub is connected to a mobile device running the iComfort
maintenance application through a Lennox-managed local network connection. (This is considered a
transient state because the mobile device will disconnect from the Lennox-managed network when the
task at hand is complete.)
1.4.4. Wi-Fi Connection
The following terminology is used in this troubleshooting section:
S
Router Signal Strength (RSSI). RSSI is an indication of the signal strength of the Wi-Fi router being re­
ceived by the scanning device (i.e., smart phone). Therefore, the higher the RSSI number (or less nega­
tive in some devices), the stronger the signal.
S
802.11a, g and n are wireless networking specification that extends throughput up to 130mbps using the
2.4 GHz band.
S
Internet Protocol Address (IP address). This is a numerical label assigned to each device (e.g., com­
puter, printer, thermostat) participating in a computer network that uses the Internet Protocol for communi­
cation. An IP address serves two principal functions: host or network interface identification and location
addressing.
S
Electromagnetic Interference Causing Poor Connectivity
Locate both the thermostat and router away from other devices that could possibility interfere with wire­
less communications. Some examples of other devices that could interfere are:
n
Microwave ovens
n
Wireless cameras
n
Portable phones and bases
n
Baby monitors
n
Wireless speakers
n
Bluetooth devices
n
Garage door openers
n
Neighbor's wireless devices.
To eliminate a possible source of interference, temporally disable any devices and see if Wi-FI perfor­
mance has improved.
