4.1 Ventilation stage button
The desired ventilation stage can be selected via the "Ventilation stage" button
The five ventilation stages + "OFF" can be selected by repeatedly pressing the button.
The factory setting upon delivery is ventilation stage 0.

The sequence of ventilation stages is 0 ("OFF") -1-2-3-4-5 and ventilation stage 0 starts again when the button is pres-
sed again after ventilation stage 5. The selected ventilation stage is indicated via the LEDs 1-5.

4.2 Operating mode button
There are three operating modes available "reversing mode with HR", "cross ventilation" and "supply air mode". An
operating mode can be selected by pressing the button
> supply air mode. Operating mode „ reversing mode" starts again when the button is pressed again during operating
mode "supply air mode".
The factory setting upon delivery is operating mode "reversing mode" (i.e. heat recovery).

– Reversing mode (HR)
The "reversing mode" function enables maximum heat recovery. In reversing mode, the KWL EC 45 units change bet-
ween supply air and extract air mode. The heat accumulator integrated in the KWL EC 45 unit absorbs the heat from
the passing air in extract air mode and emits this heat into the incoming outside air in supply air mode. Thus, up to 88
% of the extract air heat is emitted into the outside air. The reversing mode (change of fan direction) activates every 60
seconds.
– Cross ventilation mode (CV)
The "cross ventilation" function enables ventilation without heat recovery. For this purpose, the KWL EC 45 unit, which
is connected to terminal 10, is switched to supply air mode. The KWL EC 45 unit, which is connected to terminal 11, is
switched to extract air mode.
– Supply air mode (SA)
The "supply air mode" function enables the combination with a extract air fan (ELS, M1). For this purpose, the KWL EC
45 unit, which is connected to terminal 10, is switched to supply air mode. You can also set whether the units, which
are connected to 11, also change to supply air mode.
