Abstract
An air condition control unit is provided with an EEPROM previously memorizing respectively different specific numbers of indoor control units and power supply means. Further provided thereto are power supply judging means for judging whether a remote controller receives the power from another indoor control unit by monitoring power source lines, and power not-supply determining means for determining the unit of its own to be a unit which does not supply the power to the remote controller when the power supply judging means judges the remote controller receives the power. In addition, provided thereto are power supply timing means for setting a power supply timing based on the specific numbers and power supply determining means for determining the unit of its own to be a unit which supplies the power to the remote controller for making the power supply means supply the power to the remote controller when the power supply judging means judges the remote controller to be in a state that no power is supplied thereto at the power supply timing by the timing means. Consequently, the indoor control units are standardized and the power can be without failure supplied to the remote control…
