Control from a Premium cooker hood
Selectable functions
The control panel of the cooker hood has three pushbuttons.
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 have three speeds:
away, home and 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 selected.
Demand control (optional equipment)
Demand control is possible with the following optional equip-
ment:
•
Separate 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 mini-
mum fan speed mode.
•
Separate 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.
•
Separate 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 compensates the negative pressure by
automatically increasing the supply airflow. The switching sig-
nal can be transmitted to the ventilation unit from the cooker
hood or a differential pressure switch, for instance.
•
Home−Away switch.
Should be located close to the front
door. When the button is pushed, the ventilation unit switch-
es to operation in the Away mode and this saves energy. An
ordinary electric switch can be used.
•
Occupant detection sensor.
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 increase 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 varies.
•
DDC control.
Enables you to change the fan speed from a
remote controller, for instance.
•
Modbus gateway.
A Modbus field bus card for remote
control of the ventilation unit.
