Problems solved by technology

[0002] A conventional central air-conditioning system consists of at least one or more outdoor units, a plurality of indoor units, and a control box corresponding to each indoor unit (collectively referred to as a wire controller). Connect multiple wire bundles with the wire controller, these wire bundles are composed of mains AC power wires, low-voltage DC power wires and digital signal control wires, in view of the installation position of each indoor unit and wire controller in the central air-conditioning system The distance and spacing are different, and the total amount, length and cost of the corresponding wire bundles will also be different, and it also increases the complexity and difficulty of installation and maintenance.
