Abstract
A carbon dioxide sensor () measures the carbon dioxide concentration of inside air. An inside air control system () controls the carbon dioxide concentration of the inside air based on a measured value obtained by the carbon dioxide sensor (). If the measured value obtained by the carbon dioxide sensor () returns to a predetermined normal range after falling outside the normal range, the controller () of the inside air control system () performs a determination operation. The determination operation is an operation for supplying outdoor air to the carbon dioxide sensor () to determine whether or not the carbon dioxide sensor () is normal.
