1. An air conditioner comprising:

  • an air-conditioning control unit that controls air-conditioning running based on running information and operation setting information stored in a nonvolatile memory of the air-conditioning control unit, the running information is action information during running;

    a data read and write unit to which a storage medium configured to store therein data is physically and removably connected, the data read and write unit writes the running information and the operation setting information transmitted from the air-conditioning control unit in the storage medium and reads the running information and the operation setting information stored in the storage medium from the storage medium;

    a data control unit that, during air-conditioning running, transfers, at a pre-determined periodic timing, the running information and the operation setting information transmitted from the air-conditioning control unit to the data read and write unit to be written in the storage medium; and

    an operation unit that inputs the operation setting information for performing an operation of the air-conditioning running,the air-conditioning control unit is mounted on a same control board as the data read and write unit and the storage medium which stores data for the air-conditioning control;

    the operation unit that inputs the operation setting information is separated from the control board on which the air-conditioning control unit is mounted;

    whereinwhen the air-conditioning running is re-started after being stopped due to board replacement or initialization of the nonvolatile memory,the air-conditioning control unit causes, responsive to the re-start or initialization, the data read and write unit to read the running information and the operation setting information which was stored at the periodic timing in the storage medium before running was stopped,then the data control unit transfers, responsive to the re-start or initialization, after the data read and write unit reads the running information and the operation setting information which was stored before running was stopped, to the air-conditioning control unit, the running information and the operation setting information that are from before the running was stopped and that are read from the storage medium by the data read and write unit,then, responsive to the re-start or initialization, after the running information and the operation setting information that are from before the running was stopped are transferred to the air-conditioning control unit, the air-conditioning control unit runs the air-conditioning control based on the running information and the operation setting information that are from before the running was stopped and that are received from the data control unit,wherein the air-conditioning control unit automatically transmits the running information and the operation setting information to the data control unit on a regular basis,wherein the operation unit transmits, to the air-conditioning control unit, information for setting an interval at which the air-conditioning control unit automatically transmits the running information and the operation setting information to the data control unit.
