ALARM OUTPUT DEVICE AND ALARM OUTPUT METHOD

Conventional technology is based on the prerequisite that an appropriate value has been established in advance as a target value for power consumption, but this does not does not take into consideration the possibility of establishment of an excessively low value. In order to solve the aforementioned problem, an alarm output device is provided, characterized by determining at all times whether or not electric power expected to be consumed within a regular interval of time exceed the set upper limit target value and by outputting an alarm in case that the electric power exceeds the set upper limit target value at approximately the point in time at which a predetermined interval of time commences or by outputting instructions for changing the set upper limit target value within such interval.
