Air Quality Thresholds
If Air Quality is selected in Display Settings, the device will monitor each CO2, TVOC, PM, RH, and Temp sensor
present and will display accordingly. The device will calculate an average air quality based on up to 5 sensors
and display good, fair, or poor accordingly.

The average air quality is calculated as follows for the sensors that have been enabled(see Air Quality settings on
page 9):
1.
Each reading is rated according to the above thresholds and given an air quality rating. For each sensor,
a good rating is given 90%, fair is given 60% and poor is given 0% air quality.
2.
The average of all sensors’ air quality is calculated.
3.
The average air quality is assigned based on the following thresholds. These thresholds can be adjusted
in AV28 Good-fair and AV29 fair-poor.
a.
Good
≥
75
b.
55 < Fair < 75
c.
Poor
≤
55
