(G) Effect of the Invention As is apparent from the above description, the present invention is such that when the voltage signal or the current signal supplied from the main control unit to the remote controller changes according to the operation of the device, the voltage signal or the current signal is changed. Level is detected by the remote controller and the operating status of the device is displayed on the remote display according to the detected level.
Not only is it easy to use, but the current signal or voltage signal from the remote controller to the main controller becomes constant due to the operation of the constant current circuit or constant voltage circuit. Even if a voltage signal or a current signal supplied to the setting section changes, there is no concern that the operation signal corresponding to the operation in the setting section is affected, so that complicated and precise remote control can be performed.
