380 Band failure: Setpoint is outside the expected range
The watchdog processor detects a band failure.
Setpoint or actual value of an actuator is not in the
expected range.

381 Actuator dynamics is missing
The ÜP has not detected the required dynamics for
at least one actuator.
Problem: The actual position of the actuator has not
changed in the last 24 hours.
– Check air damper and gas damper for jamming.
– In case of stiffness, clean the damper and
make it smooth running again.
– Check the function of the actuator without
damper and replace if necessary.
– Reset fault and switch mains voltage OFF
and ON again.
– If the error still exists, replace the device.

required data are missing
Reason:
– Invalid channel configuration
– A non-existing channel is activated
– An inactive channel is marked in the channel
