FRESH AIR

If ventilation is installed, fresh air is
periodically drawn into your home
through your heating and cooling system .
The schedule is based on installer-
calculated requirements . The thermostat
will limit fresh air when the outdoor
temperature is too hot or cold or the
indoor air is too humid . This unused time
will be banked and made up later when
outdoor conditions improve .
