3.4 Operating modes

3.4.1 Automatic mode
In automatic mode, the connected ventila-
tion units each ventilate and aerate altern-
ately for 70 seconds at the lowest ventila-
tion speed. A regenerator in the ventilation
unit absorbs the heat from the room air
during aeration, and emits it back into the
inflowing outdoor air during ventilation.
A light sensor in the MASTER monitors
the brightness in the room. Night mode or
day mode is switched on depending on the
brightness.
A sensor in the MASTER monitors the air
humidity in the air. If the limit values are
exceeded, the ventilation units therefore
start to reduce the air humidity:
– In day mode, the air is exchanged via
alternating aeration and ventilation at an
average ventilation speed. In this case,
a regenerator in the ventilation unit ab-
sorbs the heat from the room air during
aeration, and emits it back into the in-
flowing outdoor air during ventilation.
– In night mode, the air is exchanged
via cross ventilation in one direction
(MASTER aerated) at the lowest vent-
ilation speed in order to keep noise to a
minimum.
If the value falls below the limit value again
by five per cent, the ventilation units return
to normal mode.
The limit value for the air humidity can
be adjusted over three levels using the
buttons on the remote control.
Feedback:
– When automatic mode is activated, the
LED at the MASTER flashes white and
red once.
– If preset limit values are exceeded, the
LED on the MASTER lights up red and
remains lit.
