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 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), for safety reasons the

cooker hood electronics must only

be reset by a Miele service

technician.

Potential free connection

This enables a further appliance to be

controlled by 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.
