PROBLEM TO BE SOLVED: To perform control in a specified mode at the time of single operation of an indoor unit by stopping the operation temporarily upon detection of a failure at the time of single operation of the indoor unit and setting the blade direction and fan speed for the case satisfying specified conditions even if those conditions are not satisfied when the indoor unit is operated again independently. SOLUTION: An air conditioner indoor unit control section 1 determines the operating mode and delivers drive signals based on the fan speed, blade angle and liquid crystal display data to a fan motor 2, a blade drive motor 3 and a liquid display 4. At the time of single operation control of an air conditioner, an internal/external communication abnormal flag is turned on when the operation is interrupted temporarily due to abnormal internal/external communication and the air conditioner is operated at the blade direction and fan speed for the case satisfying specified air conditioning conditions under a specified operation mode only when the internal/external communication abnormal flag is turned on. Consequently, the blade direction and fan speed for the case satisfying specified air conditioning conditions can be realized even it that conditions are not satisfied. |
