Why does my Lennox S40 Smart Thermostat say, "Transitioning to Next Schedule"?
FAQ , Thermostats , Troubleshooting Modified: March 19, 2026
If your system is currently running a schedule, and you have Smooth Setback Recovery enabled, the thermostat knows how long it takes to achieve the temperature for the next setpoint and will start to cool or heat your house to achieve the setpoint by the start of the new time period. When this occurs, the "Transitioning to Next Schedule" status message appears in the left side of the home screen.
