NOVELTY - The apparatus (10) has a power supply judgment unit (41) judging that electric power is supplied among a commercial power source (12), an independent electric power generator (13) and a storage battery (14). A starting control unit (42) is started in low load to preset an air-conditioner (21) if operation of the air-conditioner is turned ON when judging that the electric power is supplied from the storage battery in the power supply judgment unit. A power supply signal receiving unit receives a storage battery use signal from a managed apparatus when supply of the electric power is received.    USE - Control apparatus i.e. personal computer, for a home energy management system (HEMS) to control distribution of electric power supplied with respect to a managed apparatus from a commercial power source, an independent electric power generator e.g. solar cell, fuel cell and internal combustion engine electric power generating apparatus, and a storage battery e.g. lithium ion battery, nickel-hydrogen battery and NAS battery. Uses include but are not limited to a lighting equipment, TV, air-conditioner, laundry apparatus, electric vehicle and a refrigerator.    ADVANTAGE - The apparatus allows operation of the air-conditioner to reset to a normal operation mode with big power consumption when the electric power is supplied from commercial power sources or independent electric power generator, so that performance of the air-conditioner can be fully exhibited and comfort within the apparatus can be improved. The apparatus ensures operation that stabilizes other managed apparatuses, while receiving supply of electric power from the storage battery.    DETAILED DESCRIPTION - The power supply signal receiving unit is a power supply signal reception section. The managed apparatus is a lighting equipment (22) and a TV (23).
