Abstract
A controller of an indoor unit included in an air-conditioning system determines whether or not a communication error with the outdoor unit is an energization error that only occurs during an energization time in which electric power is fed from a commercial power supply to the outdoor unit. The controller can also determine whether or not the communication error is a connection establishment error that occurs at a time of establishing a connection with the outdoor unit. Based on determining the cause of the communication error with the outdoor unit, the controller can drive a fan by electric power fed from an emergency power supply.
