The building management system includes: a central control system connected with a network and centrally controlling at least one sub-system accommodated in a building; a multi-air-conditioner system including an outdoor unit and one or more indoor units connected with the outdoor unit; a BACnet gateway serving as a connection passage of the central control system and the multi-air-conditioner system to allow the central control system to centrally control the multi-air-conditioner system; and a remote integrated management server that controls the multi-air-conditioner system by interworking with the BACnet gateway. Because detailed information can be managed through the remote integrated management server, that an existing building management system fails to do, the user convenience can be improved.

Abstract: A test handler (122) of the present invention includes a main body, a window (142) formed on a surface of the main body and having a size corresponding to a Hi-Fix board of M×N array (where M and N represent an integer greater than a value of =), a cover (170) detachably fixed to the main body t close a part of the window and convert the window into the test site having a size corresponding to a [M?A)×(n?B)] Hi-Fix board (where A is an integer equal to ot greater than 0 but smaller than M, and B is an integer having a value other than 0). In the test handler, the size of window is easily modified to adapt that of the Hi-Fix board of M×N array by closing or opening a part of the window using the cover. Therefore, the test handler is capable of applying Hi-Fix boards having different sizes.
