Service guide

Request replacement device

Please contact us on our service hotline or submit your complaint/service message online. Please have the following information ready: device type, serial number, commissioning report, date of commissioning, details of wiring and module type. Ideally, please tell us the event shown in the display, if known, and give us a brief description of the fault.

Take delivery of replacement device

If we are not able to further assist on the telephone, we will quickly send you a completely refurbished replacement device without accessories. You will find a return slip (RMA) for the free return of the defective device through our service partner in the parcel.

Packaging the defective device

Pack the defective device in the original packaging of the replacement device. Stick the return label to the top of the package.

Arrange a collection date

You can quickly and easily arrange a collection date online directly with the parcel service provider. You will find more information about this on the parcel service provider's website.

Hand parcel over to parcel service

Hand over the packaged device to the parcel service. This service will electronically confirm acceptance of the parcel. By using the return slip the transport costs are automatically borne by us. You can track the status of your shipment at any time using the parcel service's tracking number.
