Abstract
An air conditioner has a plurality of indoor units (3, 3, . . . ) and a single remote controller (4). The controller (4) is provided with an anomalous unit memory section (45) for a unit number of an indoor unit (3) in operation anomaly, a button operating section (42) for inputting a check signal for checking on the location of the operation anomaly, and a forcedly fan-on section (46) for outputting a forcedly fan-on signal, at the time of input of the check signal in the case that the unit number is stored, to the indoor unit (3) having the unit number. When each of the indoor units (3, 3, . . . ) causes an operation anomaly, it outputs an anomalous condition signal to the remote controller (4) and then receives a forcedly fan-on signal from the remote controller (4) to activate a fan.
