Operation with DSM 400 control module
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 cooker hood 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 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 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
–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.

All appliances must be tested for safety after they have been connected.
