Note that your device is always running on a programmed
schedule and the current operating mode is part of that
schedule. Thus, when you change the Mode,
it will only change the mode for the current program. If
you change to a different program, your Mode will follow
the new program that you have selected.
The mode selection is for the current program (Home).
You cannot assign different modes within a program.
