Disclosed herein is a control method for four-way valves of a multiple heat pump. In the control method, if even at least one of four-way valves (20) of respective outdoor units (A, B and C) is not switched to a desired mode upon switching of all of the four-way valves to the desired mode, the other four-way valves (20), switched to the desired mode, is switched to an opposite direction of the desired mode, and then all of the four-way valves (20) are switched again to the desired mode, thereby simply and rapidly correcting switching error of the four-way valves (20), resulting in normal operation of the multiple heat pump. |
