Every day use of ventilation
Ventilation is controlled with a simple and easy-to-use
control panel that is based on actual use situations.
Operation modes based on these situations cover
all the ventilation needs at your home. Selecting an
operating mode changes the functionality of the
ventilation unit accordingly. The installer of the unit
will apply the operation mode parameters when
commissioning the ventilation unit.
The control panel is normally in stand-by mode with a
dimmed display. You can activate the unit by pressing
any button.

2 = Home (when at home)
3 = Home (when at home, with boosted ventilation)

F-PL = Overpressure (when lighting a replace)
HEAt = Heating on / heating o mode
