An air-conditioning control apparatus controls an air-conditioning unit used in a central air-conditioning system that conditions a plurality of rooms in a house by a single air-conditioning unit. In the apparatus, a microcomputer starts an output of an ON command signal when started, subsequently continues the output of the ON command signal when a detected temperature inside a room is lower than a predetermined determination temperature, and stop the output of the ON command signal when the detected temperature is equal to or higher than the predetermined determination temperature. A protective opening and closing unit closes a first power supply path between a voltage input terminal and an internal alternating-current power supply line when the ON command signal outputted from the microcomputer is supplied, and opens the first power supply path when the supply of the ON command signal is stopped.
