Weighting of the temperature inputs
If the actual temperature is acquired via several temperature inputs, the values acquired can have differ-
ent weightings. The weighting can be set in the following parameters:
•
Weighting of internal measurement
•
Weighting of external measurement 1
•
Weighting of external measurement 2
If several internal measured values are acquired (multiple temperature sensors connected to physical de-
vice inputs), the measured values are averaged automatically.
Case 1: All measured values are weighted equally.
If all measured values are weighted equally, a mean value is determined from the received temperature
values. The mean value is then used as the actual temperature.
Case 2: The measured values are weighted differently – the total is 100 %
The measured values are included in the calculation of the actual temperature based on their weighting.
Example
Value 1: 21 °C; weighting 60 %
Value 2: 24 °C; weighting 40 %
(21 °C × 0.6) + (24 °C × 0.4) = 22.2 °C
