Troubleshooting and Support

Encountering issues with your Lennox S40 Smart Thermostat is not uncommon, and understanding how to troubleshoot them can save time and frustration. If your thermostat is not connecting to Wi-Fi, double check your network name and password, ensuring you’re using a secure connection physically located in your home, and never a guest network. Remember, Lennox S40 and S30 Smart Thermostats are not designed to communicate with each other. If the system is not responding to temperature changes, verify the thermostat’s settings, and that your staged heating options are configured properly.
