PURPOSE: To lighten the overload applied to a compressor by delaying the redrive of a compressor for a certain time at the time of recovery to normal condition from power failure. CONSTITUTION: When power failure is detected after the initialization of a microcomputer, a delay counter is reset by interruption of an external connection. While the delay counter is working, even if the power recovers to normal condition, and the signal for operation on of the compressor comes in, the compressor does not start operation. It is checked whether or not there is a signal of operation on of the compressor, where the power has recovered to a normal state after the delay counter has counted up, and in case of operation on, the compressor is started. |
