Explanation
Lights up if fan stage 1 is active, or with fan speed
1 – 32 % (Starting strategy is not taken into account).
Lights up if fan stage 2 is active, or with fan speed
33 – 65 % (Starting strategy is not taken into account).
Lights up if fan stage 3 is active, or with fan speed
66 – 100 % (Starting strategy is not taken into account).
Lights up if the cooling valve is open.
Flashes if opening of the cooling valve is delayed, because the heating
valve is not completely closed or the time between heating and cooling has
not elapsed.
Lights up if the heating valve is open.

programmed yet.
Lights up if the device is in test mode.
When used as a window contact:
Lights up if contact is closed.
When used as an actual value sensor:
Stays off in normal temperature range (i.e. -10 °C .. 60 °C).
Flashes in case of interruption or short-circuit in the sensor line and
temperatures outside the normal range.
For use as a window contact (only with supported function = heating or
ventilation):
Lights up if contact is closed.
With supported function = heating and cooling or cooling:
Flashes at condensate alarm, regardless of source for condensation
monitoring.
