M-WRG-II O/LFS, part no. 721007
11.7.1 Description
The “ventilation for moisture protection” option is used to set fixed, minimum ventilation
levels for day and night. The function is activated at the factory and cannot be switched
off by the user (who can only set higher ventilation levels). A humidity program which
increases the air flow as required runs continuously in background mode. This option
includes the mains switch without function so that the user cannot easily switch the unit
off (it can be switched off via the building’s fuse box, for example). This option changes
the button assignment on the ventilation unit control panels:
Button 1, 2, 3, (4): 20, 40, 60, (80) m
3
/h.
It may be combined with the external wireless sensor for humidity or CO
2
.
NOTICE
— This option can only be selected in conjunction with M-WRG-II units with humidity
and/or CO
2
control (excluding types -S 485, -TF, -TFC).
— It needs to be fitted at the factory.
