Setup and Customization Process  
Set Up the S40 Smart Thermostat  
The S40 Setup Pending badge displays on the thermostat’s home screen  
after the dealer or installer has completed their portion of the Setup Process.  
Homeowners can then complete the Setup Process by adding the Lennox®  
S40 Smart Thermostat to their user account and later customizing their  
thermostat. See “Customize the S40 Smart Thermostat” on page 8.
