When a function is selected, the color will turn to blue
meaning that the function is now “locked”.
When the locking function is enabled, the
icon will be
displayed on the homepage. When the locked function icon is
selected, it will blink indicating that the function is locked.
When the schedule setting is locked, the system prompts the
user that the weekly schedule is locked when you try to access
the week timing mode.
Note:
If the central controller is sending locking signals
to
an IDU while the touch screen wired controller also sends
a
command to the same IDU simultaneously, the locking
command from the central controller may be invalid.
