Thereafter, the main controller 300 of the control target heat exchanger 400 controls the operation of the control target heat exchanger 400 according to the control signal of the heat exchanger received from the corresponding block controller 200 (S170). As the operation of the target heat exchanger 400 is controlled, the operation state information of the target heat exchanger 400 to be controlled is transmitted to the corresponding block controller 200 by using power line communication (S180).

Next, the block controller 200 transmits the operation state information of the control target heat exchanger 400 to the central monitoring server 100 (S190), the central monitoring control server 100 is a block controller ( The operation state information of the control target heat exchanger 400 received from the display 200 is displayed on the screen through the setting display unit 120 so that the administrator can check and monitor the operation state of the heat exchanger (S200).

Through the above process, it is possible to effectively control and monitor the operation of the total heat exchanger 400 installed remotely from the central monitoring control server 100.

On the other hand, the central monitoring control system of the total heat exchanger according to an embodiment of the present invention is not only the central monitoring server 100, but each block controller 200, the main controller 300 or the room controller 500 independently of the total heat exchanger. 400 can be controlled and monitored.
