The following terminology is used:
• Received Signal Strength Indication (RSSI). This
indicates the signal strength of the Wi-Fi router
being received by the scanning device (i.e.,
smart phone). So the higher the RSSI number (or
less negative in some devices), the stronger the
signal.
• Internet Protocol Address (IP address). This is
an address assigned by your home router for
each network device (e.g., computer, printer,
thermostat).
Connection to Lennox server from your
Internet provider may take up to 4-5
minutes depending on your Wi-Fi speed
connection speed and how busy the
server may be.

Locate the thermostat and router away from other
devices that could possibility interfere with wireless
communications. Some examples of other devices
that could interfere are:
• Microwave ovens
• Wireless cameras
• Portable phones and bases
• Baby monitors
• Wireless speakers
• Bluetooth devices
• Garage door openers
• Neighbor's wireless devices
To eliminate a possible source of interference,
temporally disable any devices and see if Wi-Fi
performance has improved.

The ideal signal strength range for the thermostat
is -1 to -69 Received Signal Strength Indication
(RSSI). The signal strength can be viewed from the
thermostat interface.
1. Press NETWORK SETTINGS; This screen
shows a graphical view of options representing
OPEN and SECURE wireless networks, along
with options for adding a network.
2. Select the access point that has already been
established and connected.
3. When selecting the info icon, a screen will
appear which will display an option to forget
the network and IP address assigned to the
thermostat by your router, sub-net mask, router,
DNS and RSSI.
4. Scroll down to the last entry on this screen.
There the Wi-Fi signal strength will be
displayed (RSSI). If the RSSI signal strength
is anywhere between -9 to -69, then the signal
strength is sufficient. If outside the reference
range, then either relocate the router closer to
the thermostat, add a repeater, or move the
thermostat. Adjusting antenna on router may
resolve the issue.
