3.0 OUTSIDE Mode
NOTE: Ventilation Rate
Ventilate rate represents how much air is introduced into the indoor space from the
outside. Low values indicate low ventilation rates and potentially poor air quality.
High levels indicate excessive ventilation and potential excessive energy usage.
To obtain an accurate measurement, readings should be taken 2~3 hours after
occupancy has stabilized in a space or at a peak in daily CO2 concentrations
.
With indoor air quality control, CO2 value is an indicator of ventilation rate.
400 ppm
(Parts Per Million) is the default CO2 concentration outside (according to
ASHRAE: American Society of Heating, Refrigeration and Air conditioning
Engineers).
