3. Application

3.1 To set the airflows
The home should have continuous air change to ensure a
pleasant indoor climate and avoid damage to building ele-
ments due to humidity� The ventilation unit should be stopped
only while service work is in progress�
The airflows should be set according to the ventilation plan
and applicable regulations� For estimated values, use the sizing
curves in Section 7, Technical data� A qualified person should
set the ventilation unit's and the ventilation equipment's air-
flows using appropriate measurement equipment�
A low airflow when the home is unoccupied means economi-
cal operation� This saves on fan energy and the home heating
system does not have to heat as much air during the cold
season� An assessment of whether a low airflow is sufficient
for removing emissions, moisture, etc� from the air should be
made�
3.2 Premium cooker hood
The ventilation unit fan speeds and other settings should be
entered via the Premium control panel� When you have en-
tered these settings, the functions below will be available from
the cooker hood control panel�
• The ventilation unit fan speed� The fans inside the unit
can be controlled to operate at three speeds: Away/Home/
Boost� One single press of the button will increase the fan
speed one step� The period for the boost speed is preset to
60 minutes, after which the ventilation unit will return to
normal airflow�
• The cooker hood damper� When preparing food or carrying
out a similar activity, a 30, 60 or 120 minute damper-open
period can be selected� One single press of the button will
change the setting to the next damper-open period�
• The cooker hood lighting� On/Off�
• Alarms (flashing indicating lamps)�
3.3 Premium control panel
When the power is switched on, the ventilation unit starts
up in the Home operating mode� The start time is approx� 1
minute� After that, the control panel can be used� Likewise af-
ter a power failure, the ventilation unit starts up in the Home
operating mode, if the power failure has cleared the memory�
The functions of the push buttons are described in the image�
The indicating lamp on the control panel shows the various
functions of the ventilation unit in different colours�
1� Steady green glow: The ventilation unit is operating nor-
mally�
2� Flashing green glow: The freeze protection has been acti-
vated�
3� Orange flashing glow: The electric air heater has been
activated�
4� Flashing red glow: The automated protection system has
stopped the fans due to a malfunction�
5� Steady red glow: Alarm or a service reminder�
