2.2. Installation location
Install and use only in dry interior rooms!
Avoid condensation.
The
Sensor Sewi KNX TH-L-Pr
is installed surface mounted on walls or ceilings.
For
capturing movement
make sure that the desired area is covered by the sensor's
coverage angle and that no obstacles obstruct the recording.
When selecting an installation location, please ensure that the measurement results of
temperature and humidity
are affected as little as possible by external influences.
Possible sources of interference include:
•
Direct sunlight
•
Drafts from windows and doors
•
Draughts from ducts coming from other rooms or the outdoors
•
Warming or cooling of the building structure on which the sensor is mounted,
e.g. due to sunlight, heating or cold water pipes
•
Connection lines and empty ducts which lead from warmer or colder areas to
the sensor
Measurement variations from such sources of interference must be corrected in the
ETS in order to ensure the specified accuracy of the sensor (offset).
