After an installation of an apparatus, although a state confirmation is necessary, if a display having a high display capability is mounted to the apparatus to facilitate checking, the apparatus becomes large. Further, although it is considered that a terminal such as a personal computer is connected to an apparatus to display state information, when the apparatus is installed in a high place or a narrow gap, the connection is difficult. An apparatus is provided which includes a storage unit that stores state information on a plurality of types of states, a switching unit that switches a to-be-output state from among the plurality of types of states in response to receiving a switching operation by a user, an identification information output unit that outputs a first indication for identifying a type of a to-be-output state, and a state information output unit that outputs state information on a to-be-output state.
