When using one setting and display unit as the display unit for multiple control units, this signal is
used to inform the control unit that it has been changed as the local display unit.
When this signal turns ON, the currently selected screen reappears at the rising edge of the signal.
The setting and display unit's screen is still showing the display screen for the control unit before
the changeover, so the local screen display is changed by inputting this signal.
The display part system of a dual part system can be changed.
The display part system is changed at the rising edge of each display changeover signal.
The screen display for a dual part system is a screen for displaying one of the part systems. Thus,
which part system to be displayed is determined by these signals.
If both of these signals are started up simultaneously, they will be invalid.
