The Lennox S40 Smart Thermostat is the pinnacle of comfort, performance, and efficiency. This innovative thermostat seamlessly connects to all Lennox communicating products, automatically configuring and controlling your heating and cooling system. Enjoy a hassle-free setup process with the convenience of model and serial number recognition.

Enhance your home's comfort further with advanced accessories such as the Smart Room Sensor, Air Quality Monitor, and Wireless Extender. The S40 Smart Thermostat maintains efficient operating conditions by receiving real-time information from digital controls and the Pure Air system. It also supports conventional HVAC systems and offers Smart Zoning capabilities, providing you with precise control over your home's climate.

Boasting a user-friendly 7-inch capacitive touchscreen display with a resolution of 1280 x 800 and a 16:9 aspect ratio, this thermostat ensures a personalized and convenient experience. With multiple schedules, the Smart Away feature, live weather data, and easy installation via the Lennox Smart Technician app, the S40 Smart Thermostat adapts to your lifestyle and preferences.

Troubleshooting, system warnings, and maintenance alerts are clearly displayed on the intuitive interface, allowing you to stay informed and proactive about the health of your HVAC system. The S40 Smart Thermostat is compatible with most 24VAC furnaces, air conditioners, air handlers, and heat pumps, providing a complete total-comfort system.

To ensure a hassle-free experience, the Lennox S40 Smart Thermostat comes with a 10-year warranty against any manufacturing defects or malfunctions. It is essential to have the thermostat professionally installed by a certified HVAC installer to maintain the warranty validity. Failure to use a professional HVAC installer may result in the warranty being voided, and the item cannot be returned or refunded. Instructions on how to register for the warranty are included in the box.
