当温控开关打开时，若测得环境温度大于设定温度，则继电器吸合 启动电机工作；若测得环境温度小于设定温度，则继电器释放， 电机停止工作；(When the temperature control switch is turned on, if the measured ambient temperature is higher than the set temperature, the relay will suck in. Start the motor; if the measured ambient temperature is less than the set temperature, the relay will be released. The motor stopped working.)
