thermostat. If screen brightness is set to AUTO, the thermostat automatically
adjusts screen brightness based on surrounding room light. To set to AUTO,
go to Menu > Settings > Display and enable Auto Brightness.

Do not block the intake location. The indoor humidity percentage displays

Comfort Features

• Smart Away mode brings Lennox innovation to energy savings by doing
®
what regular programmable thermostats cannot. Rather than simply
following a set schedule, Smart Away lets the Lennox
Thermostat adapt to the homeowner's life, perfectly. Smart Away works
with the GPS in home occupants' smartphones to detect when the house is
empty. When it's sure that nobody is home, it sets the temperature to save
energy. When the Lennox
is on the way home, it returns the system to normal operation so everyone
always comes home to comfortable air.
• FEELS LIKE™ brings Lennox innovation to comfort by optimizing and
automating all the factors that affect how air feels. With the Lennox
Smart Thermostat, simply set a single temperature. The thermostat will
then take into account all the factors that affect comfort (including heating,
cooling and humidity) and create the ideal environment. It's very similar to
the "feels like" temperature on a weather report.
• Allergen Defender brings Lennox innovation to cleaner air by monitoring
the air quality and pollen levels in your zip code. When high levels of
pollutants or allergens are reported, the Lennox
automatically increases fan speed to create more clean air per hour in your
home.
• Climate IQ monitors current climate conditions and automatically removes
®
Humidity
Sensor excess humidity when necessary (requires Lennox
outdoor unit).
• Schedule IQ™ monitors for changes in the homeowner's routine. If there is
a change in routine, the S40 Smart Thermostat adapts heating and cooling
to match preset heating and cooling temperatures.
• Perfect Temperature (Single Set Point) allows a single temperature setting
to be used to cool or heat the home (non-zoning applications only).
• Supports air conditioning or heat pump units with up to four stages of heat /
two stages of compressor operation (two stages of heat pump heating, two
stages of auxiliary back-up heating and two stages of emergency heating).
• Variable - capacity / Multiple - stage Heat • Cool, universal compatibility
(gas/electric/heat pump/air conditioner). When the S40 is used with the
variable speed equipment homeowners can save up to 30% on their energy
costs over single stage equipment and 15% over two stage equipment.
• Dual-fuel capable when using Lennox
two balance points.
