The Miele DSM 400 Control module can
be used to combine the cooker hood
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 cooker hood 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 cooker hood can
only be operated when the window is
sufficiently open (see also "Warning
and Safety instructions").
When the window is closed the cooker
hood fan cannot be switched on. The
indicator lamp for the On/Off touch
control on the cooker hood will flash.
The same applies to operation with an
external motor (depending on model).
The cooker hood lighting is not affected
by this.
Take care when ventilating the room
through an open window that ventilation
is not impaired by a closed blind or
curtain.
Operation with Control module DSM 400
If the control module is disconnected
in order to operate the cooker hood
without the window contact switch
(e.g. after moving house) the cooker
hood electronics must be reset by a
Miele service technician.
Potential free connection
This enables an external appliance to
be controlled according to the switch
setting on the cooker hood fan.
– For instance it can be used to ensure
a sufficient supply of fresh air when
the cooker hood 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 cooker hood
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 cooker hood, to
be switched off when the cooker
hood is in operation.
