Lennox iComfort thermostats deliver precise comfort control, holding your home’s temperature to within 0.5°of your chosen setting. The iComfort S30’s and iComfort E30’s SmartAway™ Mode helps you stay energy efficient, even when you’re not at home.

When you return, Smart Away changes your system to a normal schedule and more comfortable temperature.
Other smart features include Allergen Defender, which monitors the air quality and pollen levels in your zip code and automatically turns the fan on to clean your home’s air when outdoor levels are high, and Feels Like™, which considers temperature and humidity to make your home feel exactly like you want it. ComfortSense thermostats give you the ability to customize settings for every day of the week, and even let you compare your monthly heating and cooling usage, so you can adjust your settings to reduce energy consumption.
LENNOX THERMOSTATS AT A GLANCE
S40 Smart Thermostat
Welcome to your home comfort command center.

FEATURES
The S40 smart thermostat from Lennox was designed alongside other smart home devices, offering compatibility with other smart technology. This can create an HVAC system that’s more efficient and easier to use than you thought possible. The S40 was developed in tandem with the Lennox Smart Air Quality Monitor and Smart Room Sensor, ensuring seamless interconnectivity.
The S40 can generate automatic maintenance and service reminders for important tasks like changing the air filters, helping keep your equipment in better shape for longer. You can even send diagnostics information to your nearest Lennox dealer, minimizing the risk of problems with prompt notifications.
The core benefit of a smart thermostat is its ability to balance optimal comfort and energy use. It can learn from your usage habits to create the most energy-efficient schedule for heating and cooling, managing adjustments for you. Pair the S40 smart thermostat with Smart Room Sensors for advanced features like adjusting individual room temperatures based on occupancy.
With the S40 smart thermostat, you can also control indoor air quality equipment such as air purification systems. Lennox strives for perfect air, which includes clean and healthy indoor air, free from pollutants and microorganisms.
