Connection of the temperature sensor
Connect the cable of the measuring sensor to the clamp (No. 4) of the evaluation
electronics (connection is reverse polarity protected). The cable connection may be
extended up to 20 m maximum. Connect the bus +/- to the KNX terminal (No. 1).
Notes on installation
Evaluation electronics must not be exposed to water. This could result in the electronic
being damaged. A relative air humidity of 95% must not be exceeded. Avoid bedewing.
Maintenance
The temperature sensor should regularly be checked for dirt and cleaned, if required.
Due to safety reasons, the sensor should always be disconnected
from the bus current when performing maintenance and cleaning
works (e.g. by deactivating/removing fuse).
