»MOUNTING ADVISE ROOM SENSORS
The Accuracy of the room sensors are influenced by the technical specifications as well as the positioning and the installation type.
During Assembly:
•Seal mounting box (if present).
•Installation type, air draught, heat source, radiation heat or direct sunlight can affect the measurement.
•Bulding material specific properties of the installation place (brick-, concrete-, partition wall, cavity wall, …) can affect the measurement.
(e.g.: Concrete accepts room temperature variation slower than cavity walls)
Assembly not recommendet in…
•Air draught (e.g.: close to windows / doors / fans …)
•Near heating sources,
•Direct sunlight
•Niches / between furniture / …
»BUILD-UP OF SELF-HEATING BY ELECTRICAL DISSIPATIVE POWER
Sensors with electronic components always have a dissipative power, which affects the temperature measurement of the ambient air. The
dissipation in active temperature sensors shows a linear increase with rising operating voltage. This dissipative power has to be considered when
measuring temperature. In case of a fixed operating voltage (±0,2 V) this is normally done by adding or reducing a constant offset value.
Thermokon transducers can be operated with variable operating voltages. The transducers are set at the factory with a reference operating voltage
of 24 V =.
At this voltage, the expected measuring error of the output signal will be the least. Other operating voltages, can cause a measurement deviation
changing power loss of the sensor electronics.
A recalibration can be carried out directly on the unit or via a software variable (app or bus).
Remark: Occurring draught leads to a better carrying-off of dissipative power at the sensor. Thus temporally limited fluctuations might
occur upon temperature measurement.
»APPLICATION NOTICE FOR HUMIDITY SENSORS
At regular environmental condition, it is recommended to calibrate the sensor annually to check the compliance with the accuracy
required in the application. The following conditions can damage the sensor element or lead in long therm to loss of the specified
accuracy:
Contamination (e.g. dust / fingerprints)
Aggressive chemicals
•Ambient conditions (e.g. condensation on measuring element)
Do not touch the sensor
elements!
Re-calibration or exchange of the sensor element are not subject of the general warranty.
»INFORMATION ABOUT SELF-CALIBRATION FEATURE CO2
All gas sensors are subject to drift. The degree of drift is dependent on the use of components and product design. In addition, the following
environmental conditions, among others, can accelerate/ favor the aging and wear of the sensors:
•Mechanical stress (also due to temperature fluctuation)
•Contamination (dust / fingerprints e.g.)
•Abrasive chemicals
•Environmental influences (high humidity / condensation on measuring element)
An internal self calibration function with dual channel technology
»INFORMATION ABOUT INDOOR AIR QUALITY CO2
EN 13779 defines several classes for indoor air quality:
CO2 content above the content in outdoor air in ppm
Standard indoor air quality
Moderate indoor air quality
»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.
