Selecting this icon will bring up user and installer
menus. A red circle with a number inside of it indi-
cates a notication is active.
Function Away
When the away icon is touched, the system will au-
tomatically use energy saving settings - heat-to 62
(16.5) and cool-to 85 (29.5). Temperatures can be
adjusted by pressing on the available temperature
setting (i.e., heat-to or cool-to). To exit away, press
the cancel icon. In a zoning system, all zones are
set to a single heat-to and cool-too setting. Note
that when manually selecting Away from the home
screen, the Smart Away feature (if enabled under
settings) will be temporally disabled until Away is
canceled.
System Status Heating System is heating the home.
System Status Cooling System is cooling the home.
System Status Humidifying
If humidication equipment is installed and cong-
ured, the system will display this message when
adding humidity to the air in the home.

Table 1. System and Event Icons
Icon Function Screen Text Purpose
System Status Dehumidifying
The system can be used in cooling mode to help
remove excessive humidity as determined by the
user setting. Go to menu > settings > humidity >
and turn on dehumidify. Then adjust the acceptable
low and high humidity levels in the home with the
dehumidication set-point slider.
System Status Defrosting The system is defrosting the outdoor unit coil (only
when required). Heat pump only.
System Status Emerg. Heat
All heat pumps operating in northern climates below
35°F (1.6°C) normally need a supplemental heating
source. Usually it is in the form of electric heating
provided by the indoor unit. Other sources could
be gas, oil, or hot-water back-up systems as well.
The supplemental heat is also referred to as “sec-
ond-stage” or “back-up” heating, with “rst-stage”
being the heat pump only. Emergency heat is when
you use your supplemental heat (2nd stage) by it-
self, without the use of your heat pump (1st stage
heat). Not available for non-heat pump systems.
System Status Aux. Heat
Is only available with heat pump system. If outdoor
temperature is above the high balance point, only
the heat pump will operate - default 50°F (10°C)
high. If outdoor temperature is below the low bal-
ance point, only auxiliary heating will operate - de-
fault 25°F (-4.0°C) low. If outdoor temperature is
in-between the high and low balance point, both the
heat pump and auxiliary heat sources can operate.

10
Table 1. System and Event Icons
Icon Function Screen Text Purpose
System Status Will start soon
A ve minute safety delay prevents the compressor
from operating too soon after shut-down to allow in-
ternal pressures to equalize.
This delay icon will also appear when immediate-
ly changing demand. For example immediately
changing from cooling to heating (gas, electric or
heat pump heating).
System Status Ambient lockout
This indicates that either the outdoor temperature is
above or below the balance point temperature set-
tings. The low balance point setting prevents heat
pump heating below the set point and back up heat
will be used. Typically the default is 25°F (-4.0°C),
but that setting can be adjusted by your dealer. At
25°F (-4.0°C) or below for example, only auxiliary
heating (electric or gas) is used.
If the high balance point is set to 50°F (10°C ) for ex-
ample, which is also adjustable by your dealer, then
auxiliary heat will not be allowed. Only heat pump
heating will be used. Anytime the outdoor tempera-
ture is below or above the balance point tempera-
ture settings, the ambient lockout notice will appear
on the home screen.
Function Transitioning to
next schedule
The system is following an active schedule and is
transitioning to the next temperature setting based
on a time indicator.

Function System Under
Test
Typically occurs when the system has had a power
interruption. The thermostat starts to look for the in-
door and outdoor controls. Sometimes the outdoor
control takes longer to boot up and therefore does
not respond to inquiry by the thermostat. Recycle
power to system may resolve issue.

tem is in away mode, the horseshoe is grayed-out
and shows the “away” status text. In order to exit
away mode, the user can press the “cancel” icon.

Smart Away
Smart Away is a feature that can be enabled once
you have created and registered your account. Both
Home Info and Account options must be completed
before this option can be enabled.
Smart Away is a feature that can be enabled once
you have created and registered your account. Both
Home Info and Account options must be completed
before this option can be enabled.
The Smart Away feature depends on the iComfort
Thermostat App running on your mobile device
(smart phone or tablet) and being logged in to your
account. It is also required for Wi-Fi and location
settings to be enabled on your mobile device. An-
droid devices must also have the location mode set
to “high accuracy.” Consult your mobile device user
guide for instructions.
Smart Away can also be enabled from your mobile
device once you have installed the Lennox iCom-
fort Thermostat App and logged in. Go to the menu
> settings > away and turn ON Smart Away. To
allow the mobile device you are on to use this fea-
ture, turn ON participate. The away fence option will
appear and by default, the setting is two miles (3
km). The range for this setting is 2 to 6 miles (3.00
to 9.50 km).
Inner and Outer Away Fences
The inner away fence is set by the user anywhere
between 2 to 6 miles (3.00 to 9.50 km) on the
mobile app. This setting can be di󰀨erent for each
participating mobile device. When any of the partic-
ipating mobile devices are located inside of its inner
away fence, the system will not be in Smart Away;
the system will use the temperature set points de-
ned by the schedule or what was manually set.
Once the inner away fence is set, the outer fence for
each participating mobile device will be automati-
cally calculated by the Smart Away algorithm.
Transition Set Points
When the closest participating mobile device is
between the inner and outer away fences, the ther-
mostat will show the Smart Away indicator. The
system will use transition set points to heat or cool
the home. The transition temperature set points are
automatically calculated by the Smart Away algo-
rithm using a combination of the home and away
set points.
Away Set Points
Once all participating mobile devices have moved
outside the transition range, the thermostat will
continue to show the Smart Away indicator, and the
user-set away set points will be used to control the
system.
Example: Away set points are 65ºF (18.5ºC) for
heating and 85ºF (29.5ºC) for cooling. When the
away fence is set to two miles for all participating
mobile devices, and the closest participating mobile
device is within the 0-2 mile (0 to 3.22 km) range
of the home, the system is considered home; the
system will use the set points from the schedule or
what was manually set. If the closest participating
mobile device moves into the 2.1 to 8 miles (3.40 to
13.04 km) range, the system is considered in tran-

20
sition, and the system will start to either increase
or reduce the heating or cooling set point. Once all
participating mobile devices have moved beyond
the 8.1 mile (9.50 km) range from the house, the
system sets the set points to the away set points
(65ºF for heating and 85ºF for cooling).
Multiple Devices
It is possible to have more than one mobile device
participating in Smart Away for this system. The
away fence can be set to the same value or di󰀨erent
values for each mobile device. The thermostat will
not show the Smart Away indication until all devices
have moved past their inner away fence, and the
system will not reach the user-set away set points
until all devices have moved past their outer fence.
NOTE: Starting with Android version 10, when
allowing the mobile app access to device
location, you must select “Allow all the
time” for the Smart Away feature to work
correctly.

determining the “feels like” temperature based on
outdoor temperature, indoor temperature plus in-
door relative humidity. On/O󰀨:
