The Lennox Wireless Extender improves the connection between the S40 Smart Thermostat and smart sensors, such as the Smart Room Sensor and the Smart Air Quality Monitor, in larger homes or areas with reduced coverage or “dead spots”. This strengthened connection nearly doubles the coverage area and thus enhances reliability, performance, and usability.

Get the most from your communicating equipment by making sure they have the strongest connection.
