IMPORTANT
Protect homeowner investment and peace of mind with active monitoring of
system operations through the Lennox S40 Smart Thermostat. This feature is
free of charge and provides basic maintenance reminders, alerts homeowner

diagnostics with the Lennox dealer to troubleshoot and fix problems. This
proactive care helps eliminate downtime and avoid unnecessary service
visits and repair costs, ensuring nothing short of perfect air.
Please share this information with homeowner as you ask them to accept the
Advanced Diagnostics & Remote sharing permissions.
