M-WRG ventilation programs
NOTICE
For ventilation units from the M-WRG series, the ventilation level and volumetric flow
rate are related as follows: ventilation level 1 corresponds to 15 m
3
/h, ventilation level 2
corresponds to 20 m
3
/h, ..., ventilation level 9 corresponds to 90 m
3
/h and ventilation
level 10 corresponds to 100 m
3
/h.
8.2.1 “Supply air operation (summer mode)”
Symbol
Default view
Description
The ventilation unit runs in supply air operation with limited
heat recovery. 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 15 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.
8.2.2 “Extract air operation”
Symbol
Default view
Description
The ventilation unit runs in extract air operation with limited
heat recovery. This operating mode can be selected to route
used air to the outside (extract air 50 m
3
/h, supply air 15 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.
