What is a zone?
FAQ , Thermostats , Troubleshooting Modified: March 19, 2026
A zoning system enables greater control of temperature in areas of a home. By directing air flow to a specific zone in a household, homeowners may benefit from enhanced comfort. A zone corresponds to an area of your house where you can independently control the temperature from other zones. Each zone is controlled by its corresponding Lennox S40 Smart Thermostat or Lennox Smart Zoning System.
