    摘要: To exercise control so that, when power is restored in the case of there having been a prower cut, the motor does not run simultaneously with other devices which reqire large amounts of power when starting to run. This invention there is provided improved freezer control unit, which exercise to ccntrol by providing power cut detector 10, which detects that the power source which drives freezer 5 has undergone a power cut, and stopping the signal of signal holding circuit 4, which outputs the `Run` signal, by the signal of this power cut detector 10 when a power cut occurs so that freezer 5 does not restart automatically when power is restored.
