2.10. Filters
The HRU 400 has two filters, one for each airflow. Both filters
are placed in the ventilation unit in such a way that they protect
the exchanger from contamination. In addition, the filter in the
air supply also protects the user against dust and other
contaminants in the sucked in outside air.
There are different types of filters:
●
Filter ISO16890 Coarse 65% (G4) .
This coarse filter is mainly used to filter relatively large dust
particles from the air. This mainly protects the heat
exchanger against penetrating dirt.
●
Filter ISO16890 ePM1 55% (F7).
In addition to the coarser dust particles, this fine filter also
stops finer dust particles (pollen). People with allergy
complaints in particular can benefit from this.
Over time, the filters will become dirty, which will increase the
energy consumption of the ventilation unit. It is therefore necessary
that the filters are cleaned according to the instructions and
eventually replaced.
2.11. Interface
The device is equipped with an interface with two buttons and two
LEDs. On the interface, the filter warning can be reset using the
button at the top (A). The LED (1) shows the status in terms of
messages and errors. The wifi connection can be activated with
button (B) and the status of the appliance and that of the wifi mode
is shown with LED (2). In the event of error messages, both LEDs
flash.

ä Attention
!
In the case of a new house, the filters of the ventilation unit must
be cleaned after 1 week and replaced after 3 months!

Warning!
The HRU 400 must be fitted with the matching original filters
at all times! Without filters, the unit can suffer irreparable
damage.
