Abstract: A wired remote controller is provided. The wired remote controller includes a display panel, a wired interface that is connected to an indoor unit by wire, a memory in which information on a power capacity for each indoor unit model is stored, and a processor that receives power from the indoor unit through the wired interface and communicates with the indoor unit through the wired interface, wherein the processor is configured to receive information on power consumption of the indoor unit through the wired interface, identify a power capacity corresponding to the indoor unit based on the information on the power capacity stored in the memory, and adjust the brightness of the display panel based on the identified power capacity and the received power consumption of the indoor unit.

Abstract: An air conditioner device includes a first and second communication lines configured to provide communications between a first slave device and a master device through a voltage difference. The master device having a voltage sensor configured to sense a voltage between the ends of the two communication lines and a processor configured to, based on the sensed voltage being less than or equal to a preset voltage, transmit a command to perform connection control such that one of a first resistor on a side of the master device and a third resistor on a side of the first slave device serves as a pull-up resistor, and to perform connection control such that at least one of a second resistor on a side of the master device and a fourth resistor on a side of the first slave device serves as a pull-down resistor.
