Precise Comfort™ Technology
When used with a Lennox indoor or outdoor unit which includes a compatible
communicating control, the icomfort Wi-Fi thermostat becomes part of a
Precise Comfort™ system.
Precise Comfort™ Cooling (XC/XP25) — Keeps the temperature within
1/2 degree of the desired set point – (it does this by adjusting the airflow
in increments as small as 1% or larger as needed for the ultimate temper
ature control)
Precise Comfort™ Heating (SLP98V) — Keep the temperature within
1/2 degree of the desired set point - (it does this by adjusting the airflow
in increments as small as 1% or larger as needed for the ultimate temper
ature control)
icomfort Wi‐Fi®Thermostat
The communicating icomfort Wi‐Fi®thermostat is an electronic 7-day pro
grammable touch screen thermostat with color display. It also offers en
hanced 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 autochangeover
mode permits control of heating, cooling, humidification, and dehumidifica
tion without user involvement.
The icomfort Wi‐Fi®thermostat can connect to the internet using your home's
Wi-Fi access point. After online registration is completed, weather information is
automatically sent to the thermostat, and you will have full access to the thermo
stat from anywhere using a remote internet connection via computer, smart
phone, Android™ device, iPhone®or iPad®.
The thermostat stores system parameters in nonvolatile memory (retains data
when electrical power fails or is turned off), and includes on‐board help screens.
Indoor Air Quality accessories are supported with time‐based notification of con
sumables including media filters, UVC bulbs, humidifier pads, and PureAircat
alyst service / replacement.
Thermostat Lock-Out
A “lock” icon at the bottom center
screen (shown in the picture), indi
cates the thermostat is either partial
ly- 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 Features page
“display settings” described on Page 8.

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 connected
and powered on, the icomfort Wi‐Fi®
thermostat's Home screen is
displayed. 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.
“Wi-Fi” in the bottom lift corner is the “button” to access
the Wi-Fi settings screen. Wi-Fi with a beneath it indicates
a prior connection to the server has been lost. If a connection had
been lost, then re-established, the triangle goes away.
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 “Features screen”
(fig. 3) by pressing
- access and view active ser
vice alerts by pressing the
icon
- access help screen by press
ing 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 17 for details on humidity control.

Setting Humidity Controls
NOTICE
Humidifier and dehumidifier controls must be setup by the installer 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

Humidification and Dehumidification Settings: To adjust humidify con
trols (humidifier), click the button to go to the Feature screen; then select

pacities, increasing efficiency by operating at a higher sensible to total
ratio.
Moderate  The system supplies indoor airflow that balances effi
ciency and comfort.
Humid  The system supplies lower indoor airflow at all compressor
capacities, improving humidity removal by operating at a lower sens
