Abstract
To obtain a multiple-unit air conditioning apparatus capable of detecting, when improper wire connections are made, improper wiring and eliminating an improper wiring state without performing a re-wiring work. When an operation command for an indoor unit Y, received from indoor unit control means, does not match a refrigerant circuit of an indoor unit Y whose refrigerant circulation is controlled by outdoor unit control means, operation patterns are extracted on the basis of the number of operating indoor units Y. A refrigerant circuit in which a refrigerant is circulated is switched in accordance with the operation patterns. Each wireconnected to the indoor unit control meansof each indoor unit Y is associated with each refrigerant circuit controlled by the outdoor unit control means, and recognition of wire connections is changed.
