<P>PROBLEM TO BE SOLVED: To provide an air conditioner including a configuration capable of giving an instruction for a specific treatment from the outdoor unit side without increasing cost and without opening a cover of an outdoor unit or a lid of an electrical equipment box. <P>SOLUTION: The outdoor unit serially measures temperature by using an outdoor air temperature sensor. If the measured temperature changes by 15°C or more within a unit time (one second) set in advance, the outdoor unit recognizes it as an instruction of a maintenance personnel. After detecting the temperature change, the outdoor unit measures and stores the outdoor air temperature every two seconds. The stored temperature is converted to an indication of "0" and "1" by a threshold value. A treatment (a command) corresponding to a temperature changing pattern by the indication is selected and executed from a plurality of specific treatments. <P>COPYRIGHT: (C)2012,JPO&INPIT |
