摘要： PROBLEM TO BE SOLVED: To provide a multiple-type air conditioner comprising a plurality of indoor units operated in the same mode, in a state where operating conditions except for the mode can be independently set in each indoor unit. SOLUTION: Slave units 3b-3d are operated in a mode according to an operation mode of a master unit 3a. The master unit 3a accepts setting of the operation mode and setting of operating conditions except for the operation mode from a remote controller 100a corresponding to the master unit 3a. The slave units 3b-3d accept setting of the operating conditions except for the operating mode from remote controllers 100b-100d corresponding to the slave units 3b-3d, but does not accept setting of the operation mode. Since each of the indoor units 3a-3d is operated under conditions suitable for each indoor space, even when the indoor units 3a-3d are installed in the different indoor spaces, more comfortable air-conditioning control is made.
