Abstract
An apparatus can prevent a voltage drop a the power supply that would occur when AC power is supplied to a large number of air conditioners from the same power supply simultaneously as when recovering from a power failing. The timing of applying the reset signal to a microprocessor in the apparatus is set arbitrarily by a time setting circuit. A time setting switch is used to set to an arbitrary value for the time elapsed from the generation of the reset signal to the start of an air conditioner compressor. According to the setting of this switch, the microprocessor performs a control to change the delay time for the start of the air conditioner. When the power is restored after a power failure, it is possible to prevent the air conditioners from restarting simultaneously and therefore reduce the voltage drop in the power supply.
