Where are the best locations to have the Smart IAQ Monitor installed?
FAQ , Air Quality , Installation Modified: March 19, 2026
The Smart Air Quality Monitor needs 24V power connection, so we recommend your dealer uses the same connection used for the S40. If you wish to have it installed in a different area, your Lennox dealer can use a 24V transformer for power as long as it is within reach of the allowable communication range of the S40 thermostat. You can place the Smart Air Quality Monitor in a common living area. The Smart Air Quality Monitor needs to be installed on the wall.
