NOTICE
Use this thermostat only as described in this manual.
icomfort Wi−FitThermostat
The communicating icomfort Wi−Fi thermostat is an electronic 7−day
programmable touch screen thermostat with 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)
capability, and equipment maintenance reminders. The thermostat’s au-
tochangeover 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 wireless Wi−Fi access point. After online registration is com-
pleted, weather information is automatically sent to the thermostat, and
you will have full access to the thermostat from anywhere using a remote
internet connection via computer, smartphone, or iPad.
The thermostat stores system parameters in nonvolatile memory (re-
tains data when electrical power fails or is turned off), and includes on-
board help screens.
Indoor Air Quality accessories are supported with time-based notifica-
tion of consumables including media filters, UVC bulbs, humidifier pads,
and PureAircatalyst service / replacement.
Thermostat Lock−out
A lock" icon at the bottom center
screen (shown in the picture), indi-
cates the thermostat is either par-
tially− or fully−locked.
Partially−locked, any user can adjust the temperature up or down to set a
hold" for a selectable time.
Fully−locked, no one can make any changes to the thermostat’s settings.
To unlock, press and hold the lock" icon for 5−6 seconds.
To lock the thermostat, access Screen lockout" through the dash-
board’s display settings" described on Page 7.

icomfort Wi−Fi7−Day Programmable Communicating Thermostat

Start up
In event of power failureIf a power failure occurs,
when the power comes back on, the thermostat will reboot
and when complete, the HOME screen will return.
What the Home screen tells you...
After the thermostat and the
system has been fully con-
nected and powered on, the
icomfort Wi−Fithermo-
stat’s Home screen is dis-
played. Figure 1 shows a
display and describes what
the thermostat is telling you.
Note that set to heat or
cool communicates that the
system is operating in
manual mode; if it were in
program mode, the heat or
cool button would read
summer program is on (or
other named program).
Other information...
Until and unless the indoor temperature is at or between
the two settings (70 to 75 degrees in this example), the system
should run until it does measure within that temperature range.
The Wi−Fi indicator is (not ), therefore, the thermostat is
connected with your wireless network router.
Away mode sets the thermostat for energy saving while you are gone
for an extended period of time. In this mode, the system will only
come on if indoor temperature falls below 62 degrees (for heating) or
if indoor temperature rises above 85 degrees (for cooling).
What you can do from the Home screen...
Typically, what every homeowner wants from an air
conditioning system is to be able to control that
system using a convenient device to
adjust heating, cooling, and the
level of humidity in the home.
From this screen you may:
− adjust temperature
settings
− access menus to change
the program mode
− change how the
fan operates
− access the dashboard"
(fig. 3) by pressing
− access and view active
service alerts by pressing
the icon
− access help screen by
pressing the ?" icon.
Adjusting the temperature and changing the
system mode of operation is described fully
beginning on Page 14.
Adjusting the humidity, even if no physical humidifier or
dehumidifier is present, may also be available, provided the
installer has implemented the feature during setup.
See Page 16 for details on humidity control.

spring...program is ON) indicates which program is running. In this
mode, change temperature by pressing a set temp button, which pro-
duces an up or down arrow, then use the arrows until the cool to" (or
heat to") number is at the desired temperature (see Ain figure 19).
While changing the setting, the other options menu appears (see Bin

You may select one of the hour buttons (1, 2, 8, or 24) if desired. If you
select custom, a time/date appears and you have the option of setting
the hold for any length of time (see Cin figure 19).
After a hold is set, the other options menu disappears and a message
will state when the hold expires, along with a cancel option should you
choose to revert back to the program.

ting will be that the program is held until the next period.

Setting humidity controls
NOTICE
Humidifier and dehumidifier controls must be setup by the in-
staller or these controls will not be visible. If your system has one
or both of these features and the controls are not visible, contact
your Lennox dealer for proper setup.
If the controls have been setup, they will appear and will be ON.
To adjust humidity controls (either to humidify or dehumidify), click the
button to go to the dashboard controls; then select system settings
button. Some systems may have a humidifier and some may have a de-
humidifier, while still other systems may have both (as shown in figure
20). You can control either or both from this screen.
Both controls work identically. Touch the button of the humidity control
you want to address; if it says (de)humidifier is OFF, one touch will
change it to (de)humidifier is ON and bring on the RH setting button be-
low that button. When you touch the set−to button, the arrows appear,
allowing you to change to the desired humidity setting.
Remember that the humidify" control only operates while in the heating
mode and dehumidify" only operates while in the cooling mode.
