»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:
CO2content above the content in outdoor air in ppm
Standard indoor air quality
Moderate 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!
