Precise Comfort™ Technology

When the iComfort Wi-Fi® thermostat is used with a Lennox indoor or
outdoor unit which includes a compatible communicating control, it
becomes part of a Precise Comfort™ system.

 Precise Comfort™ Cooling (XC/XP25) — This feature keeps the room

temperature within 1/2 degree of the desired cooling setpoint. The airflow
is adjusted in increments as small as 1% to provide ultimate temperature
control.

 Precise Comfort™ Heating (SLP98V) — This feature keeps the room

temperature within 1/2 degree of the desired heating setpoint. The airflow

is adjusted in increments as small as 1% to provide ultimate temperature
control.

iComfort Wi-Fi® Thermostat

The communicating iComfort Wi-Fi® thermostat is an electronic 7-day
programmable touch-screen thermostat with a color display. It also offers
enhanced capabilities which include: humidification measurement and control,
dew point adjustment control, dehumidification measurement and control,
Humiditrol® Enhanced Dehumidification Accessory (EDA) compatibility, and
equipment maintenance reminders. The thermostat's autochangeover mode
permits control of heating, cooling, humidification, and dehumidification without
user involvement.

The iComfort Wi-Fi® thermostat can connect to the internet using your home's
Wi-Fi access point. After online registration has been completed, weather
information is automatically sent to the thermostat. You also will have full access
to the thermostat from any remote location using an internet connection via
computer, smartphone, Android™ device, iPhone® or iPad®.

The thermostat stores system parameters in nonvolatile memory to retain data
and settings when electrical power fails or is turned off. The thermostat also
includes on‐board help screens.

Indoor Air Quality accessories are supported with time‐based maintenance
notifications which remind you when to check or replace media filters, UVC
bulbs, humidifier pads and PureAir™ catalytic inserts.

Thermostat Lock-Out

A lock icon at the bottom center of the
screen (shown in the picture),
indicates the thermostat is either
partially or fully locked.

When the thermostat is partially
locked, any user can adjust the temperature up or down to hold a setting for a
selectable time period. To lock the thermostat, access “Screen lockout”
through the FEATURES screen “display settings” described on Page 8.

When the thermostat is fully locked, no one can make any changes to the
thermostat's settings. To unlock the thermostat, touch and hold the lock icon
for 5 to 6 seconds.

Start -Up

In event of power failure —The thermostat will reboot after power is

restored. When the reboot is complete, the HOME screen will return.

WHAT THE HOME SCREEN TELLS YOU...

After the thermostat and the
system have been fully connected
and powered on, the
thermostat's Home screen is
displayed. Figure 1 shows a
display and describes what the
thermostat is telling you.

When the system mode is set to
heat or cool, the system
is operating in manual

mode;

When a particular program

has
been selected, program name will
be displayed on the system mode
button (e.g., summer program is on).

OTHER INFORMATION...

The system will run until the indoor
temperature is within the range specified
by the selected cooling and heating
setpoints (70 to 75 degrees in this
example).

The “Wi-Fi” button in the bottom left corner provides access
to the Wi-Fi setting screen. Wi-Fi with a

beneath it indicates
a prior connection to the server has been lost. When the Wi-Fi
connection is re-established, the triangle goes away.

Away Mode sets the thermostat for energy-saving system operation
while you are gone for an extended period of time. In this mode, the
system will only come on if the indoor temperature falls below 62 degrees (for
heating), or if the indoor temperature rises above 85 degrees (for cooling).

WHAT YOU CAN DO FROM THE HOME SCREEN...

The Home Screen provides you with convenient

access to adjust heating and cooling setpoints,

as well as humidity levels in your home.

From this screen you may:

- adjust temperature
settings

- access menus to change the
program mode

- change how the
fan operates

- access the “Features screen”
(fig. 3) by touching

- access and view active
service alerts by touching the

icon

- access help screen by
touching the “?” icon

Temperature adjustment and system mode of

operation selection are described fully

beginning on Page 14.

If the installer has activated the indoor humidity feature,

you will be able to set the desired humidity level in your home

even if no physical humidifier or dehumidifier is present.

See Page 17 for details on humidity control.

Connecting to a Home Wi-Fi Router

Check the router utility program or contact service provider for help.

The Wi-Fi thermostat must be close enough to the Wi-Fi router to ensure a
good communications signal between the thermostat and the router. (Hint:
use a smart phone with Wi-Fi and Wi-Fi finder application to locate and
determine signal strength.)

NOTE - The thermostat will not be able to reliably connect to the router
if the received signal strength indicator (RSSI) shows a larger negative
number than 70 i.e. 75, etc.

Secure Connection Recommended! Verify that the router is
compatible with and set to operate in either 802.11b, 802.11g or 802.11n

wireless network modes. Check router utility program or contact
service provider for assistance.

Below are some possible conditions that will cause wireless interference
with the thermostat resulting in poor signal reception.

 Portable phones and bases
 Baby monitors
 Wireless speakers
 Bluetooth devices
 Garage door openers
 Neighbors' wireless devices.

To eliminate a possible source of interference, temporarily disable any
devices and see if Wi-Fi performance has improved.

Troubleshooting Wi-Fi Connection

The following terminology is used in this troubleshooting section:
 Router Signal Strength (RSSI). RSSI is an indication of the signal

strength of the Wi-Fi router being received by the scanning device (i.e.,
smart phone). Therefore, the higher the RSSI number (or less negative
in some devices), the stronger the signal..

 802.11b, g and n are wireless networking specification that extends

throughput up to 130mbps using the 2.4 GHz band.

 Internet Protocol Address (IP address). This is a numerical label

assigned to each device (e.g., computer, printer, thermostat)
participating in a computer network that uses the Internet Protocol for
communication. An IP address serves two principal functions: host or
network interface identification and location addressing.

Electromagnetic Interference Causing Poor Connectivity

Locate both 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.

Router Signal Strength (RSSI)

The ideal signal strength range for the iComfort Wi-Fi® thermostat is -1 to -69
RSSI. The signal strength can be viewed from the thermostat interface. Use
steps 1

1. Press NETWORK SETTINGS; this screen shows a graphical view of
buttons representing Wi-Fi options OPEN and SECURE wireless
networks and a button for adding a network.

507342-01

Page 24

2. Select the access point that has already been establish and connected
too. There are two options to select from which are connect and
Router info. Select Router Info and verify the RSSI strength. If the
signal is anywhere between -1 to -69, then the signal strength is
sufficient. If outside this range, the either locate the router closer to the
thermostat or add a signal repeater.

Remember that walls, appliances, equipment and other various barriers will
reduce signal strength.

Router Signal Strength (RSSI)

The signal strength can be viewed from the thermostat interface. Use the
following procedure to discover the Wi-FI router signal strength at the
installation location of the thermostat.

1. Touch NETWORK SETTINGS to display your Wi-Fi connection.
