HOME VENTILATION
Control from a Premium cooker hood
Selectable functions
The control panel of the cooker hood has three pushbut-
tons. Besides switching the cooker hood's lighting on and
off, two control functions can be set as follows:
• Fan speed. The fans in the ventilation unit can be con-
trolled to operate at three speeds: away/home/boost.
The supply air fan can operate at a lower speed than
that of the extract air fan. The period for operation
in the boosted speed mode is preset to 60 minutes,
after which the ventilation unit fans will decelerate to
normal speed.
• The shut-off damper of the cooker hood. When
preparing food or carrying out a similar activity, a 30,
60 or 120 minute damper-open period can be se-
lected.
Demand regulation (control)
Demand control is possible with the following optional
equipment:
• Timer. 24-hour/weekly timer with settable times,
for when you want the ventilation unit fans to run
at normal speed. At other times, the unit runs in the
economical minimum fan speed mode.
• Boost timer. A manual pushbutton switch that can
be installed at an optional location. The pushbutton
switch can be located in a laundry room or the like, for
example.
• Fireplace switch. A manual pushbutton switch that
can be installed at an optional location. The function
generates excess pressure in the home and in this way
causes an updraught in the chimney, which prevents
smoke from entering the room when you light the
log-fire.Negative pressure compensation. When the
cooker hood is in use, negative pressure arises in the
home since the extract airflow becomes substantially
higher than the supply airflow. This function compen-
sates the negative pressure by automatically increasing
the supply airflow.
• Home−Away switch. Should be located close to the
front door. When the button is pushed, the ventilation
unit switches to operation in the Away mode and this
saves energy.

• Presence detector. The sensor detects movement in
the home and transmits a signal to the ventilation unit
to increase the fan speed. This function is well-suited
for use in premises not used around the clock, such as
in schools, day nurseries, offices, etc.
• Humidity sensor. The sensor detects when the
humidity rises and transmits a signal to the ventilation
unit to increase the fan speed. It can be located in a
sauna, a bathroom, a laundry room, etc.
• Carbon dioxide sensor. The sensor detects an in-
crease in carbon dioxide and transmits a signal to the
ventilation unit to increase the fan speed. It is suitable
for use in rooms where the number of occupants var-
ies.
