Ventilation modes

The Vallox ventilation unit has five ventilation modes:
  • At Home — Use this mode when the apartment is occupied. The Vallox ventilation unit has been set up according to the ventilation plan. The At Home mode changes the indoor air at the recommended rate approximately once in two hours.
  • Away — Use this mode when the apartment is vacant for a longer period of time, e.g. during a trip or longer absence. By default, the Away mode’s ventilation speed is 30% lower than the speed of the At Home mode.
  • Boost — Use this mode to enhance ventilation when there is a large number of people in the apartment or for other reasons. By default, the Boost mode’s ventilation speed is 30% higher than the speed of the At Home mode.
  • Custom — Use this mode e.g. when lighting a fire in a fireplace. The mode is primarily used to create a momentary overpressure in the apartment.
    IMPORTANT:
    Prolonged overpressure can damage the building structures.
  • Automatic — Use this mode, if the ventilation unit should maintain optimal ventilation automatically.
