         7 . The control method of  claim 2 , wherein selecting the drying course comprises:
 setting a drying target based on a washing target that is set for the washing course according to the laundry in the washing drum; and   selecting, among the plurality of drying courses, the drying course corresponding to the drying target.   
     
     
         8 . The control method of  claim 7 , further comprising:
 performing the washing course; and   after completion of the washing course, performing the drying course based on receiving, at the dryer, the laundry from the washing drum.   
     
     
         9 . A control method for a laundry treating apparatus including a washing drum, a washing machine driving unit configured to rotate the washing drum, a washing machine first controller configured to control the washing machine driving unit, a washing machine interface, a washing machine second controller configured to control the washing machine interface, a drying drum, a dryer driving unit configured to rotate the drying drum, a dryer first controller configured to control the dryer driving unit, a heat exchanger configured to generate heated air, a dryer interface, and a dryer second controller configured to control the dryer interface, the control method comprising:
 based on the laundry treating apparatus being in a washing standby mode, supplying power to the washing machine second controller while restricting supply of power to the washing machine driving unit, the washing machine interface, and the washing machine first controller;   based on the laundry treating apparatus being in a drying standby mode, supplying power to the dryer second controller while restricting supply of power to the dryer driving unit, the heat exchanger, the dryer interface, and the dryer first controller;   based on the laundry treating apparatus being released from the washing standby mode, supplying power to the washing machine first controller, the washing machine driving unit, and the washing machine interface;   receiving a washing course through the washing machine interface;   receiving, through the washing machine interface, a control command requesting recommendation for a course to be performed by the dryer;   based on receiving the control command through the washing machine interface, transmitting, from the washing machine second controller to the dryer second controller, information related to the washing course; and   supplying power to the dryer interface based on the dryer second controller receiving the information related to the washing course.   
     
     
         10 . The control method of  claim 9 , further comprising:
 selecting a drying course among a plurality of drying courses executable by the dryer driving unit based on the dryer second controller receiving the information related to the washing course; and   displaying the drying course on the dryer interface.   
     
     
         11 . The control method of  claim 10 , further comprising:
 measuring an amount of laundry in the washing drum based on receiving the washing course through the washing machine interface;   transmitting, from the washing machine second controller to the dryer second controller, information including the amount of the laundry in the washing drum; and   displaying a predicted time for completion of the drying course on the dryer interface.   
     
     
         12 . The control method of  claim 11 , further comprising:
 setting the drying standby mode based on an elapse of a preset reference time after displaying the predicted time.
