What if the hood lighting does not work after installation?

Check the connection of the lighting switch on terminal ①, the grounding, and that the module is properly plugged into the hood. Perform an electrical safety test.

Does the module require any special maintenance?

No specific maintenance is required. Clean the housing with a dry cloth if necessary. Ensure no moisture enters the interior.

Functional description

The control module enables the following:

• The cooker hood hob lighting can be switched on and off via a light switch integrated in the domestic installation.
  If the cooker hood has a dimmer, dimming is also possible.
• The potential-free connection is used to control another appliance depending on the switch status of the cooker hood fan.

Installation

Before installation, disconnect the cooker hood and the components to be connected from the power supply.

A position is provided on the cooker hood for installing the control module. This position is shown in the images at the end of these operating instructions. However, the control module may also be installed at another suitable location. Make sure that the control module housing is earthed. An earthing wire is provided.

• Remove the cooker hood if this is necessary to install the control module. Please observe the installation instructions supplied with the cooker hood.
  If the control module will be difficult to access after installation, connect the relevant components before installation (see "Electrical connection").

Ensure that the connection cable and electrical connections for the connected components are laid correctly. They must not be kinked or crushed.

• Secure the control module with the screws supplied.
  Insert the connection cable for the control module into the bushing on the cooker hood electronic module.

Connecting the light switch

The cooker hood hob lighting can be switched on and off and dimmed (depending on the appliance features) via a light switch integrated in the domestic installation. The lighting can also continue to be operated on the cooker hood.

Remove the lid from the control module.

Connect the light switch to connection ①.
- Secure the cable with the strain relief provided.
- Close and screw on the lid of the control module.
If earthing cannot be ensured using the fixing screws, connect the earthing wire provided.

After all components have been installed, carry out an electrical safety check in accordance with local regulations (e.g. VDE 0701-1 in Germany).

Connecting the potential-free contact

The potential-free connection can be used to control other appliances depending on the switch status of the cooker hood fan.

When connecting ventilation appliances, the advice of a building regulations inspector must be sought.

The contact does not supply a defined voltage (potential-free). This means that the connection is suitable for universal application. The maximum switching capacity of the contact is 230 V/2 (1) A. The contact closes when the On/Off button for the cooker hood is switched on. The indicator light for the On/Off button and the indicator light for the second fan setting will come on.

Remove the lid from the control module.

Connect the relevant components to connection ②.
- Secure the cable with the strain relief provided.
- Close and screw on the lid of the control module.
If earthing cannot be ensured using the fixing screws, connect the earthing wire provided.

After all components have been installed, carry out an electrical safety check in accordance with local regulations (e.g. VDE 0701-1 in Germany).

Central extraction unit

The potential-free contact of the control module A can, for example, be used in an EXT/EXTA model cooker hood that is connected to a central extraction unit. The contact can be used to actuate an electrically operated shut-off valve B, which is upstream of the central extraction unit.

The shut-off valve must be suitable for switching with a potential-free normally open contact.

The fan power is dependent on the fan used () and the design of the extraction system. The fan power is not controlled via the cooker hood control elements.

The components in the central extraction unit are not part of the Miele delivery programme.

If in any doubt, ask your building regulations inspector prior to installation.
