Abstract

PURPOSE:To simplify indoor unit to unit wiring and discriminate a set membership in automatic mode by deciding automatically an indoor unit connected with an outdoor unit as master equipment and an indoor unit disconnected with the outdoor unit as sub equipment. CONSTITUTION:An indoor unit has a transmission signal from an outdoor unit since power is supplied. When a transmission signal is received, the indoor unit is discriminated as a master unit. When no transmission signal is received for a specified time, the indoor unit is discriminated as a sub unit. More specifically, an indoor unit 3 is connected with the outdoor unit 2 by way of a connection wiring 7 and serves as a master unit while an indoor unit 4 is disconnected with the outdoor unit 2 and serves as a sub unit. The master indoor unit 3, when it receives cooling operation directive from a remote controller 1, allows a control section 3A examine if a temperature adjuster is operating or not. When the adjuster is not operating, the master unit outputs stop command to the outdoor unit by way of a transmission circuit 3c. When the adjuster is operating, the control section checks a temperature adjuster for an indoor unit 4 for its operation. If it is not operating, stop command will be output to the outdoor unit 2 while operation command will be transmitted when it is operating.
