NOTE:
The warranty does not apply for units
with no documented air amount measuring.
NOTE:
It is very important to write down all the
changes made to the parameters. This way the
information is backed up in case the automation
gets damaged (for example by a lightning).
Measurements view
You can follow the temperature, humidity, heat
recovery efficiency among other measurements in the
eWind Measurements list shown in the measurements
