The first normally closed switch of the bypass contactor and the fan are connected with the power supply in series. The temperature control switch and the coil of the electricity-saving contactor are connected with the power supply in series. The coil of the time relay is connected with the power supply. The two-shift control circuit and the coil of the bypass contactor are connected with the power supply in series. The third normally closed switch of the bypass contactor and the multi-shift control circuit are connected with the power supply in series.
