Temperature Measurement
Select, whether a
malfunction object
is to be sent if the sensor is faulty.
Use
Offsets
to adjust the readings to be sent.
The unit can calculate a
mixed value
from its own reading and an external value. Set
the mixed value calculation if desired. If an external portion is used, all of the following
settings (threshold values, etc.) are related to the overall reading.
The
minimum and maximum readings
can be saved and sent to the bus. Use the
"Reset temperature min/max. value" objects to reset the values to the current readings.
The values are not retained after a reset.
