<p>When an infrared transmission/reception section (13) of an indoor unit (1) receives from a wireless remote controller (3)a command signal for turning on ventilation operation, a first EEPROM (11) of the indoor unit (1) and a second EEPROM (23) of an outdoor unit (2) store information on the turning on of the ventilation operation. A blower in a humidifier unit (22) is activated, and a switching damper connected to an air supply/discharge tube (6) is switched to discharge indoor air to the outdoor or to suck outdoor air into the indoor. When the ventilation operation is stopped once by power supply failure, the ventilation operation is resumed, after the power is recovered from the failure, based on the information of the turning on of the ventilation store in the first EEPROM (11). This prevents inconvenience of ventilation operation being stopped despite that fact that no command by an operator to stop the ventilation operation is received.</p> |
