Indoor Air Quality system settings tables
The following tables contain the Indoor Air Quality system settings and their
details. Default settings are shown in bold. Some settings are only present
dependent upon the value of other settings.
The use of the included outdoor temperature sensor (recommended) enables
additional Indoor Air Quality functionality. If the outdoor temperature sensor
was not enabled in the HVAC system settings, HVAC system setting 16 (Outdoor
Sensor) will be presented before entering the Indoor Air Quality system settings.
