(Problems to be solved by the invention) By the way, when a plurality of air conditioning units are group-controlled in the same operating state by the operation control means such as the remote controller as described above, the same operation is performed as a whole between the air conditioning units. In order to be able to perform, the specified air conditioning unit is specified as the master unit, and the determination operation in this master unit (for example, whether to perform either cooling or heating operation based on the room temperature,
It is common to control each air conditioning unit in the same operating state as a configuration that follows the judgment operation of the master unit as a slave unit of the master unit, while representing other components such as time management during operation with a timer. Is done in a regular manner.

The present invention has been made in view of such a point, in particular, each air conditioning unit is in a normal state in many cases, paying attention to that the air conditioning unit of the slave unit follows the determination operation of the air conditioning unit of the master unit, The purpose is to presume that the air conditioner unit of the slave unit will be in the normal state at the start of operation (when the power is turned on), and only the operation information of the air conditioner unit of the master unit is taken into the operation control means. At that time, the air conditioner units of the master unit and the slave unit are uniformly controlled so as to be in an operating state according to the operation information of the air conditioner unit of the master unit which is taken in all at once.
Start operation of all air conditioning units in the same operating condition all at once,
This eliminates the time required to sequentially capture the operating states of the air conditioner units of slave units when the power is turned on,
The purpose is to shorten the standby time from the start-up of the power supply to the actual start of operation so that the operation can be started early.
