CONFIGURATION
The Thermokon Bluetooth-Dongle (Item-No. 668262) is required for Communication between
USEapp and USE-M/USE-L LRW-products. Commercial bluetooth dongles are not compatible.
Application-specific reconfiguration of the devices can be carried out using the Thermokon USEapp.
The configuration is carried out in the voltage-supplied state.
The configuration-app and the app description can be found on the website

USER ADVICE
After a certain time, dirt in the air can collect on the filter and then adversely affect the operation of the sensor. Under normal ambient condition an
annual maintenance is recommended. Rinse the filter after cleaning with distilled water and dry it using clean oil-free air or nitrogen. Extremely
contaminated filters should be replaced. At extreme ambient conditions, e.g. corrosive gases, the humidity sensor may have to be changed.
The bluetooth dongle snaps in the connector, when removing the bluetooth dongle hold the board down to
prevent pulling out the board.

MOUNTING ADVICE
For detection of water condensation, the sensor must be mounted on the coldest point of the
medium. Please ensure a good thermal contact to the measuring medium. A thermal
connection between sensor und medium with heat conducting paste is necessary. Mounting
effects by means of included cable ties (binders). Mounting can be made directly on a pipeline.
The sensor surface may be damaged by an aggressive and solvent-contaminated ambient.
Always keep the sensor clean and free of dust and dirt. A dirt film may affect the sensor's
switching characteristic.
Note the mounting side of the metal strip (see the figure A).
In order to avoid dust deposits, the sensor should be installed at the bottom of the pipe if
possible (see the figure B).
