9.5.5.1 Damper control states and message texts on the display
When the damper control is activated/deactivated, the operating states of the
damper actuators are shown on the display. This makes it possible to analyze any
faults that occur while the actuator is opening or closing.
The damper control state and the display of this state on the PMI are dependent
on the limit value for open or closed dampers OR on the state of the 'Main
damper'.
