Ventilation modes

Four ventilation unit modes:

At home — Use this mode when the dwelling or premises are occupied.

Away — Use this mode when the dwelling or premises are unoccupied, e.g. during a trip or other long absence.

Boost — Use this mode to increase the ventilation rate, e.g. when there are more people than usual in the dwelling or elsewhere on the premises.

Custom — Use this mode when, for example, you are making a fire in the fireplace. The mode is primarily used to create momentary overpressure in the dwelling.
