Automatic air recirculation
control AUC
Principle
Automatic air recirculation control AUC detects
pollutants in the outside air. The supply of out‐
side air is shut off and the interior air is recircula‐
ted.
General
When the system is activated, a sensor detects
pollutants in the outside air and controls shut-off
automatically.
When the system is deactivated, outside air
flows into the interior continuously.
Continuous recirculated-air mode deteriorates
the air quality in the interior and condensation on
the windows increases.
