Appendix A

Requirements according ISO 9869-1:2014

4.1

Always use the supplied double-sided adhesive tapes to mount the sensor since it has been calibrated for it.
Inside and outside sensors must be mounted exactly opposite to each other at the same wall for good
results.

Use the supplied sensor clips to mount the sensor. 
Avoid direct solar radiation onto the sensor. 
Place the sensor between 5-10cm next to the heat flux or surface temperature sensor. 

The duration of the measurement should be at least 72h.
A temperature difference between inside and outside temperature of at least 5°C during the entire period
is recommended.
If surrounding conditions are strongly fluctuating it might take longer than 72h to assess an ISO 9869
compliant U-value. In this case a multitude of 24h is recommended on top of the 72h time period.

Mounting of the surface temperature sensor and the (combined) surface temperature/heat flux sensor

Mounting of the ambient temperature sensor

DISCLAIMER: 

The above restrictions, recommendations, materials, etc. do not cover all possible

cases  and  items.  This  document  is  not  to  be  considered  complete  and  is  subject  to  change
without  prior  notice.  In  particular,  greenTEG  assumes  no  liability  for  damages  caused  by  the
installation/de-installation of the system to/from the wall.

Charging of the Measurement System

With the supplied power supply, it takes approximately 5 hours to charge the Base Station, however we
recommend it not to be unplugged as battery life is only 48 hours. 
The node battery lasts approximately 2 years and can be replaced once empty. 
For additional chargers and batteries visit our e-shop or contact us.
