Product Description - Vaillant VAZ RC Betriebsanleitung

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.
Note
Select eco mode in order to ensure
that, even in strong wind, the room
is ventilated correctly and the air
humidity is regulated.
3.4.2 eco mode
In eco mode, the ventilation function is
deactivated and the wind guard fins on the
ventilation units are closed.
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. If the air exceeds the preset limit
value, 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 standby mode.
The limit value for the air humidity can
be adjusted over three levels using the
buttons on the remote control.

Feedback:
– When activating eco mode, the LED at
the MASTER flashes red once.
– If eco mode is active, the LED at the
MASTER flashes white and red once a
minute.
– If preset limit values are exceeded, the
LED on the MASTER lights up red and
remains lit.
3.4.3 Aeration/ventilation
The aeration or ventilation function can be
activated in manual mode. In this case, the
ventilation units operate permanently at
the highest ventilation speed.
When aeration is activated, all of the vent-
ilation units continuously convey fresh air
from outside to inside the building. In doing
so and where necessary, the regenerators
in the ventilation units emit stored heat to
the inflowing outdoor air.
When ventilation is activated, all of the
ventilation units continuously convey used
air from outside to inside the building.
Feedback:
– When activating the aeration/ventilation,
the LED at the MASTER flashes red
once and then flashes red again after
three seconds.
– If the aeration/ventilation is active, the
LED at the MASTER flashes red once a
minute.
Note
To achieve improved exchange
of air, it is appropriate to also
open the windows when ventila-
tion/aeration is activated.
3.4.4 Cross-flow ventilation
In manual operation, the cross-flow vent-
ilation function can be activated. In this
case, the ventilation units operate perman-
ently at the lowest ventilation speed.
