Abstract
An indoor unit performs a control operation to not supply power to a load device through a power/communication line simultaneously with other indoor units. An air conditioning system may includes an indoor unit including a microcomputer to output a power application signal to supply power to a load device through a power/communication line, and a duplicate power application prevention unit to interrupt the power application signal from the microcomputer when the power is simultaneously applied to the power/communication line by a different indoor unit, to prevent the power from being duplicately applied to the power/communication line.
