In this way, the wire control mode of the indoor unit is one-control-many, which can be divided into one wire controller connected to more than two sets of indoor and outdoor unit systems, or multiple wire controllers. Connect one set of indoor and outdoor unit systems. When one wire controller is connected to more than two sets of indoor and outdoor unit systems, according to the outdoor unit dial address of the outdoor unit and the indoor unit dial address of the indoor unit, the wire controller is controlled to communicate directly with the master indoor unit in each set of indoor and outdoor unit systems connected, and/or, to communicate indirectly with the slave indoor unit connected in series with the connected master indoor unit, so as to achieve one control multiple. When multiple wire controllers are connected to one set of indoor and outdoor unit systems, the bus system controls the wire controller to communicate directly with the connected master indoor unit, and/or, to communicate indirectly with the slave indoor unit connected in series with the connected master indoor unit, so as to achieve one control multiple.

As shown in FIG4 , the embodiment of the present disclosure provides another method for controlling a bus system, including:

S401, when the indoor unit is powered on and initialized, the bus system determines the wire control mode of the indoor unit according to the first indoor unit dial address of the indoor unit.

S402, when the wired control mode of the indoor unit is one-control-many, the bus system controls the wired controller to communicate directly with the connected master indoor unit, and/or to communicate indirectly with the slave indoor unit connected in series with the connected master indoor unit.

S403, when the wired control mode of the indoor unit is one-to-one, the bus system controls the wired controller to communicate directly with the connected master indoor unit.

By adopting the method for controlling a bus system provided by the embodiment of the present disclosure, the bus system includes multiple wire controllers, each of which can be directly connected to and communicated with a master indoor unit in one or more sets of indoor and outdoor unit systems, and indirectly connected to and communicated with a slave indoor unit connected in series with the master indoor unit directly communicating with the wire controller through the bus, so that one-to-one or one-to-many control can be achieved. The indoor units connected to the wired controller can be wired in any combination on the bus. There is no need to wire the wired controller to each indoor unit, which simplifies the wiring method and operation, and reduces the occurrence of communication failures. At the same time, the wired control method of the indoor unit is first determined according to the first dial address of the indoor unit, and then the wired controller is controlled to communicate with the indoor unit to control one or one control multiple according to the wired control method of the indoor unit, which can realize one control one or one control multiple at the same time. It is only necessary to set the first dial address on the indoor unit end to set one control one or one control multiple. During the communication process, the wired controller can be informed to control one control one or one control multiple without setting it on the wired controller end, which is convenient for after-sales and installation.

Each wire controller can be directly connected and communicated with the main indoor unit in one or more sets of indoor and outdoor unit systems, and can be indirectly connected and communicated with the slave indoor unit in series with the main indoor unit that directly communicates with the wire controller through the bus. It can realize one-to-one control or one-to-many control of the indoor units connected to the wire controller. The wiring can be arbitrarily combined on the bus, and there is no need for the wire controller to be connected to each indoor unit, which simplifies the wiring method and operation, and reduces the occurrence of communication failures. At the same time, according to the wire control method of the indoor unit, the wire controller is controlled to communicate with the indoor unit in one-to-one control or one-to-many control, and one-to-one control or one-to-many control can be realized at the same time. It is only necessary to set one-to-one control or one-to-many control on the indoor unit end. During the communication process, the wire controller can be informed to control one-to-one or one-to-many control without setting it on the wire controller end, which is convenient for after-sales and installation.
