Room operating modes
If a window is opened, the room controller always
switches to room operating mode Protection , i.e. the
heating or cooling output is reduced to a minimum.
Lower-priority inputs determine the operating mode.
A central operator station can use the enable Comfort
input to specify whether the room operating mode can
be switched to a higher mode than Economy , i.e. if
priority 3 influences ( room operating mode input,
presence detector, room unit) are enabled.
However, the room controller can be used to force
enabling of priority 3 influences via local Comfort mode
by ignoring enable Comfort .
