ELECRICAL LOAD SIGNAL LAMP CONTROL PART BARISTER GRY SSR71 SSR72 RY71 RED RY72 RY73 Like the above circuit, pin 1 of CN71 suply the power. And electrical load suply the power when electricaload operated. operated refrigerator, freezer to fact comp operation And if it is needness of defrosting operation, performed comp' electrical load is off, it is security of circuit. In fact, each s operation is operated to temp. sensor and absoluteness defrosting isn' operated with comp. MOVEMENT PRINCIPAL like the grid waves appear in initial power on is recieved throngh switching diode and option is judged for matrix method. when option changed power furnd off, after change and power turns on.
