To provide an electric equipment device for displaying information regarding a first electrical unit and a second electrical unit by a display unit wherein a communication means between the first electrical unit and the second electrical unit is constituted by a communication means different from a communication means between the display unit and the first electrical unit, the information regarding the second electrical unit is transmitted to the display unit through the first electrical unit, and thereby the display on the display unit can be achieved even when the communication means between the units is different.
This electrical equipment device is provided with the first electrical units 36 and 43, the second electrical unit 45, and the display unit 4 for displaying the information regarding the first and the second electrical units 36, 43 and 45. The communication means 48 between the first electrical unit 36 and the second electrical unit 45 is constituted by the communication means 48 different from the communication means 49 between the display unit 41 and the first electrical unit 36. The information regarding the second electrical unit 45 is transmitted to the display unit 4 through the first electrical unit 36.
