A heat-pump type refrigeration cycle includes at least a compressor capable of switching between cooling and heating modes. A first memory stores first reference temperature data for the cooling mode, and second reference temperature data for the heating mode. A second memory stores first set data for setting a cooling temperature and second set data for setting a heating temperature. A mode selector compares room temperature detection data with the first and second reference temperature data, in accordance with an automatic operation instruction, and outputs a first signal for selecting the cooling mode or a second signal for selecting the heating mode. A controller sets the heat-pump type refrigeration cycle in the cooling or heating mode, in accordance with the first or second signal, and controls the compressor in a drive state or a stop state, so that a comparison difference between the first or second set data and the room temperature detection data becomes zero. A monitor is connected to monitor the stop state of the compressor, and, when the stop state continues for a predetermined period of time or longer, to provide a re-selection instruction equivalent to the automatic operaiton instruction to the mode selector.
