»NOTES ON DISPOSAL
As a component of a large-scale fixed installation, Thermokon products are intended to be used permanently as part of a building
or a structure at a pre-defined and dedicated location, hence the Waste Electrical and Electronic Act (WEEE) is not applicable.
However, most of the products may contain valuable materials that should be recycled and not disposed of as domestic waste.
Please note the relevant regulations for local disposal.
»INFORMATION ABOUT INDOOR AIR QUALITY CO2
EN 13779 defines several classes for indoor air quality:
Category
CO2content above the content in outdoor air in ppm
Description
Typical range
Standard value
IDA1
<400 ppm
350 ppm
Good indoor air quality
IDA2
400.. 600 ppm
500 ppm
Standard indoor air quality
IDA3
600..1.000 ppm
800 ppm
Moderate indoor air quality
IDA4
>1.000 ppm
1.200 ppm
Poor indoor air quality
»INFORMATION ABOUT SELF-CALIBRATION FEATURE CO2
All gas sensors are subject to drift caused by components. This fact results generally in the need to recalibrate the sensors regularly.
With dual channel technology Thermokon integrates automatic self-calibration for different fields of operation. In contrast to common used ABC-
Logic sensors with self-calibration dual channel are suitable for applications operating 24 hours, 7 days a week as for example hospitals.
Manual calibration is not necessary!

»CONFIGURATION (POSSIBLE ONLY WITH TYPE LA + CO2 A)
The Thermokon bluetooth dongle with micro-USB is required for communication between USEapp and
USE-M / USE L (Item No..: 668262). 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 in the Google Play Store or in the Apple App
Store.
»APPLICATION NOTICE
The housing cover must be completely closed in order to ensure the accuracy and reproducibility of the measured values during
a test or service log via USEapp.
The Bluetooth dongle snaps into the socket easily. When removing, please fix the plug-in card (option PCB) so that it is not
unintentionally pulled out.
