Overview of the ventilation programs
There are different ventilation programs available for selection, depending on the type of
ventilation unit. The ventilation unit informs the wireless remote control which ventilation
programs it supports.
The individual ventilation programs are identified by symbols (see section 7.4 on
page 20) on the LCD display. The symbol for the active ventilation program and the dot
representing the selected ventilation unit flash. The description of the individual ventilation
programs relates to the factory default settings.
8.1
M-WRG-II ventilation programs
NOTICE
For ventilation units from the M-WRG-II series, the ventilation level and volumetric
flow rate are related as follows: ventilation level 10
corresponds to 10 m
3
/h, ventilation
level 20 corresponds to 20 m
3
/h, ..., ventilation level 90 corresponds to 90 m

8.1.1 “Supply air operation (summer mode)”
Symbol
Default view
Description
The ventilation unit only transports supply air; the extract air is
switched off. This operating mode allows the cooler outdoor air
to be routed into the building on summer nights, for example
(supply air 50 m
3
/h, extract air 0 m
3
/h).
NOTICE
Avoid using this ventilation program at cold times of year.
Otherwise the ventilation unit will constantly activate the
frost protection function or switch off altogether.
8.1.2 “Extract air operation”
Symbol
Default view
Description
The ventilation unit only transports extract air; the supply air
is switched off. This operating mode can be selected to route
used air to the outside (extract air 50 m
3
/h, supply air 0 m
3
/h).
Cross-ventilation:
If there are two ventilation units present,
cross-ventilation can be achieved on one level by setting one
ventilation unit to supply air operation and the other to exhaust
air operation.
NOTICE
Avoid using cross-ventilation at cold times of year, otherwise
the ventilation unit that is set to supply air operation will
constantly activate the frost protection function or switch off
altogether.
