Operation with DSM 400 control module
The Miele DSM 400 control module can
be used to combine the rangehood with
other components.
It enables the following:
Connection to a window contact
switch
If adequate ventilation to the room can
only be ensured by having a window
open when the rangehood is in use at
the same time as a heating appliance
which depends on the air from the
same room, then the control module
can be used to connect a window
contact switch (not supplied) to the
appliance.
Once connnected, the rangehood can
only be operated when the window is
sufficiently open (see also "Warning
and Safety instructions").
When the window is closed, the
rangehood fan cannot be switched on.
The indicator lamp for the On/Off touch
control on the rangehood will flash.
The rangehood lighting is not affected
by this.
EXT models can also be connected to a
window contact switch.
Take care when ventilating the room
through an open window that ventilation
is not impaired by a closed blind or
curtain.
The window contact switch must be
tested for safety after it has been
connected.

If the control module is
disconnected in order to operate the
rangehood without the window
contact switch (e.g. after moving
house), the rangehood electronics
must be reset by a Miele service
technician.
Potential free connection
This enables a further appliance to be
controlled by the switch setting on the
rangehood fan.
– For instance, it can be used to
ensure a sufficient supply of fresh air
when the rangehood and a heating
appliance which also depends on
the air in the room are being used
together, by switching on an air
intake fan, or opening a motorised
inlet flap as soon as the rangehood
fan is switched on.
It is important to ensure that the fan
power is sufficient and that the air
intake has a suitable cross-sectional
diameter.
– If a sufficient air intake cannot be
guaranteed, then the potential free
contact will enable a heating
appliance, which depends on air in
the same room as a rangehood, to
be switched off when the rangehood
is in operation.
See also "Warning and Safety"
instructions.
All appliances must be tested for safety
after they have been connected.
