Bosch BCC100 Quick Start Manual page 19

Please 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 System
Mode, it will only change the
mode for the current
program. If you change to a
different program, your
System Mode will follow the
new program that you have
selected.
The mode selection is for the
current program (Home). You
can't assign different modes
within a program.
Tap "Edit" to enter the
Programming screen (detailed
instructions shown on the
next page). Tap "Go" to enter
a list of available programs on
your account from the Cloud.
From there, you can switch to
a different program.
You can opt to turn
the System Off to
shut down all HVAC
operations including
fan operation.
Emergency Heat
(Em Heat) mode is
only available if you
have selected Heat
Pump as your Heat
Type and enabled
the Emergency
Heat function in the
setup menu.
