Sensors Sewi KNX AQS and Sewi KNX AQS/TH-D
• Version: 10.09.2018 • Technical changes and errors excepted.
* Follow the instructions on
Measuring accuracy
.
The product conforms with the provisions of EU directives.
1.1.1. Measuring accuracy
Deviations in measured values due to interfering sources (see chapter
installation site
)
must be corrected in the ETS in order to achieve the specified accuracy of the sensor
(offset).
During
Temperature measurement
, the self-heating of the device is taken into con-
sideration by the electronics. The software compensates the self-heating by reducing
the measured temperature by 1.0°C.
