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
elements 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 airflows using appropriate meas-
urement equipment�
A low airflow when the home is unoccupied means
economical 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, mois-
ture, etc� from the air should be made�
3.2 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 after 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 vari-
ous functions of the ventilation unit in different colours�
1� Steady green glow: The ventilation unit is operating
normally�
2� Flashing green glow: The freeze protection has been
activated�
3� Orange flashing glow: The electric air heater has been
activated� (Reheating is optional equipment�)
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�
3.3 Premium cooker hood
The ventilation unit fan speeds and other settings
should be entered via the Premium control panel� When
you have entered 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
value, e�g� 60 % relative humidity (RH), is exceeded
and switches the fan to operate in the boosted flow
mode� It can be placed in a sauna, a bathroom, a
scullery, etc� The sensor voltage is 24 V DC�
•
Separate fireplace switch.
The function can be
switched in from a control panel or a Premium cooker
hood� A separate fireplace switch (push button) can
be installed in another place, e� g� next to an open
fireplace� The speed of the extract air fan decreases
and the speed of the supply air fan increases for a
few minutes� This produces excess pressure in the
home and in this way "creates" an updraught in the
chimney, which prevents smoke from entering the
room when you light the log-fire�
• Occupant detection sensor. The sensor detects
movement in the home and increases the fan speed
to the Home value�
• Carbon dioxide sensor. It is suitable for use when-
ever the number of occupants varies� The sensor
increases the fan speed to the Boost value, when a
preset maximal value is exceeded, e�g� 900 ppm�
•
Negative pressure compensation.
Negative pres-
sure arises in the home when a separate cooker hood
or central vacuum cleaner is used, since the extract
airflow becomes substantially higher than the supply
airflow� A separate sensor (e�g� one that senses the
difference in pressure) can transmit a signal to the
controller to increase the supply air flow from the
ventilation unit to restore balance�
•
Supervision (DDC).
Certain functions can be con-
trolled from the automated building management
system of the building� See the connection schedule
for optional items of equipment in Section 7, Techni-
cal data�
• Home/Away switch.
For example, systems controlled
from a cooker hood, generally have a separate Home/
Away switch (optional extra) by the front door� The
switch starts the Away function in the ventilation unit�
The switch can be a standard switch of optional type�
