Abstract: An air-conditioning management apparatus includes: a management-side communication device; a management-side input device that receives an instruction; a management-side display device that displays information; and a management-side control device that includes a management application processing unit. The management application processing unit includes a management individual processing unit and a management comprehensive processing unit. The management individual processing unit includes: an air-conditioning-operation processing unit; an air-conditioning-initial-settings processing unit; an air-conditioning-state-monitoring processing unit; and a processing unit that performs processing. The management comprehensive processing unit performs comprehensive processing on data processed by the management individual processing unit.

Abstract: An operation device includes a control board, a case, a base member, and a protective cover located inside the case and protecting the control board by separating, inside the case, a space defined by the base member and the case into a first space for the control board and a second space exposed to the base member. The base member has an annular rib surrounding an installation hole. The protective cover has, on a surface facing the base member, a recess in an area corresponding to the rib. The rib is fitted in the recess with a leading edge in contact with the bottom of the recess. A screw inserted in the hole has a head inside a third space defined by the rib and the bottom of the recess.
