Function description

Important The ventilation system must always be running!
With the exception of the four hours during which the unit can be stopped from the
control panel, stopping the unit is not recommended. Stopping the unit for longer peri-
ods of time may result in the condensation of fresh air in the pipe installations and ven-
tilation unit, which carries a risk of water damage in the building's construction, damage
to the unit, and hygiene problems.
Stopping the ventilation, even for longer holiday periods, is therefore not recom-
mended. If necessary, turn the unit down to fan step 2 or 1 in manual operation instead.
Function The unit blows fresh outside air into the house.
Contaminated and humid air is sucked out of the kitchen, living room, bathrooms, etc.,
and then led through the unit, which uses the heat from the old air to heat the fresh
outside air, before the latter is blown into the house.
Control panel The control panel is used to set the unit's functions.
The control panel is described in greater detail on page
Automatic demand When the unit is running in automatic demand control mode, the volume of air used is

humidity sensor, which is located in the ventilation unit's exhaust duct.

• At a humidity level lower than 45% RH, the unit will make a slow downward adjust-
The set point for the automatic demand control can be adjusted using the wireless re-
mote control.
Automatic demand control is always recommended because it ensures the air change is
carried out as needed, while preventing the house from becoming excessively dry for
inhabitants, particularly during winter months.

ment. If the humidity is very low over a longer period of time, the unit will finally run
at fan step 1.
