1. A control apparatus comprising:
a controlled-object selecting switch configured to select a specified object to be controlled from a plurality of objects to be controlled and switch the object to be controlled to the selected one;
an adjustment-value changing operation unit configured to change an adjustment value indicating an adjustment amount for each of the plurality of objects to be controlled;
a control unit configured to make the selected specified object to be controlled adjust the adjustment amount by transmitting, to the selected specified object to be controlled, an adjustment-value changing command for adjusting the adjustment amount to the one indicated by the adjustment value;
a storage unit configured to store, when the object to be controlled is switched from the specified object to be controlled to an object to be controlled other than the specified object to be controlled by the controlled-object selecting switch, a pre-switching adjustment value indicating the adjustment amount before the switching of the specified object to be controlled; and
an indicator configured to indicate a position of the adjustment-value changing operation unit indicating the pre-switching adjustment value,
wherein the adjustment-value changing operation unit includes an adjustment-value changing lever that moves along a groove formed in a top surface of a housing,
wherein the indicator includes a plurality of lamps arranged side by side in a moving direction of the adjustment-value changing lever along the groove, and
wherein, when the object to be controlled is switched from the object to be controlled other than the specified object to be controlled to the specified object to be controlled by the controlled-object selecting switch, the control unit starts, after the adjustment-value changing operation unit indicates the pre-switching adjustment value by lighting a lamp of the indicator located at a position indicating the adjustment position of the adjustment-value, transmitting the adjustment-value changing command to the specified object to be controlled, and thereby makes the specified object to be controlled adjust the adjustment amount to the one indicated by the adjustment value.
