VENTILATION THE RIGHT WAY

the air that is extracted. Outdoor air and extract air are routed in separate ducts through a cross-
flow plate heat exchanger (see section 5.2.2 on page 15). You save on heating costs, increase
your living comfort and are kind to the environment by reducing CO
2
emissions. A filter also re
-
moves pollen, dust and other impurities from the outdoor air.
The ventilation units are designed for continuous operation and can be both surface-mounted and
flush-mounted. The ventilation units are low-maintenance, but
regular filter changes
are impor-
tant.
The ventilation units M-WRG-S/Z-T(-F,-FC) have six
ventilation programs which are activated using the
InControl pushbutton sensor M-WRG-T/... (see Fig.
2). The LEDs integrated into the pushbutton sensor
indicate the currently selected ventilation program.
Up to five ventilation units of the same type can be
controlled with one InControl pushbutton sensor.
The ventilation unit M-WRG-S/Z-T-F also has a
humidity control program. In addition to the humidity
control, the M-WRG-S/Z-T-FC also has an integrat-
ed CO
2
and mixed gas control program. Mixed gas-
es are volatile organic compounds (VOCs) and are
the second important measurement, after the CO
2
content, for assessing the air quality. An integrated
microprocessor calculates the optimum air renewal
from the values measured by the atmospheric humidity, CO
2
and mixed gas sensors and sets the
correct ventilation level fully automatically.
The ventilation units M-WRG-S/Z-T(-F,-FC)-FU have
between six and eight ventilation programs, depend-
ing on the version. These programs can be activat-
ed using the wireless remote control M-WRG-FUFB
(see Fig. 3). The ventilation program functionality is
exactly the same as for those ventilation units that
are controlled with the InControl pushbutton sen-
sor. The LEDs integrated into the wireless remote
control indicate the currently selected ventilation
program at the push of a button.
Section „10 Ventilation programs“ from page 23
sets out and describes the ventilation programs for
each type of ventilation unit.
