2.2. Installation location
The
Sensor Vari KNX 3L-TH-D
can be installed outside or inside the building.
The device should be protected from condensation. For critical applications in which
the formation of condensation is expected, please consult Elsner Elektronik about spe-
cial solutions.
Select an installation position on the building where the sensors can measure sunshine
without any obstructions. The weather station should not be shaded by structures or,
for example, trees. Ensure no shadow is thrown on the device by an extended awning.
Temperature measurements can also be distorted by external influences such as
warming or cooling of the building structure on which the sensor is mounted (sunlight,
heating or cold water pipes). Temperature variations from such sources of interference
