Definition Of Contaminants; Smart Air Quality Details Screen - Lennox S40 User Manual

The side switch on the SAQM when in the UP position turns on the internal fan
and transmits air quality data to the thermostat.
When the switch is set to the DOWN position, it will turn off the internal fan and
stop air quality data to the thermostat.
An alert code 70003 displays, which indicates the switch is OFF. The alert code
will automatically clear once the switch has been set back to the ON position.
While the switch is in the DOWN position, the latest reading from the SAQM
will be displayed on the thermostat. It will not update that information until the
switch is moved back to the UP position.
IMPORTANT
The dealer and homeowner may receive an email indicating that Alert Code
70003 is a no cool, no heat condition. This is not true and the HVAC system
will operate normally. This type of notification is due to alert code being
classified as a Service Urgent.
