Data Protection Statement for the use of the communication module WCM-COM and the associated App (iOS and Android version)

The communication module WCM-COM enables you to make settings on your Weishaupt heating system. This requires you to pair your device (PC, mobile phone) with the WCM-COM via the Internet or via WiFi. You can also make the settings using the App for the WCM-COM. Personal data may be collected. Compliance with the data protection laws, and thus the protection of your personal data, is very important to Weishaupt. We would like to explain in detail the data we collect and what we do to protect your data.  

 1 The data we process, how long for and for what purpose

1.1 Using the WCM-COM

Extent of data processing. With the WCM-COM and, if applicable, the App you can monitor and control the settings of your Weishaupt heating system over the Internet. An Internet connection is only established at your request. If you select this option, you are prompted to enter a PIN for authentication. The following data is then recorded and saved on Weishaupt servers during your registration:

  • your IP address (which we do not save for more than 7 days)
  • the date and the duration of access
  • the operating system of your device
  • your chosen nickname
  • the ID required to authenticate and pair the devices
  • operating mode of your heating system (for example normal operation, setback operation), as well as
  • setpoint values, actual values and timer programs

If you access the WCM-COM via the App, the following data will also be processed:

  • your IMEI, i.e. the device number (for iOS devices: the UDID) and
  • your card number (IMSI).

Your mobile number, the name of your phone, location data or other data on your smartphone will not be stored.

In addition, we store personal data only if you provide it to us, for example if you send us a message. In this case, we will ask you for certain personal data, which is necessary to perform the service requested. All mandatory data is marked with an asterisk, any other information provided by you is voluntary.

Your data will not be shared with third parties.

Purpose and legal basis. The data above is collected solely for the purpose of enabling the use of the service (for example for monitoring and controlling your -weishaupt- heating system via the Internet, downloading updates, etc.) or to be able to respond to service requests. The legal basis is therefore the contract concluded between us for the use of the WCM-COM or App or, in the case of a service requests, the preservation of our legitimate interest. Our legitimate interest in data processing lies in the purpose as described.

Duration of data storage. Your data will be stored for 3 years after the end of the year, in which you either: (1) give up the use of WCM-COM permanently or (2) otherwise terminate the license agreement or (3) we cease the support of the App. IP addresses are stored for seven days to track abuse.

1.2 Error reporting

Extent of data processing. If there are technical problems with the App, an error report will automatically be generated. This will include the following data: the operating system and version of your  device, device type, log files. This data will be sent to us when you press the button "Send error report". If the transmitted data contains personal references, these are removed immediately after transmission.

Purpose and legal basis. The data is processed to allow us to further develop the App and to facilitate troubleshooting. The anonymous data is stored by us for statistical purposes. Processing is subject to your consent, which will be obtained via a pop-up when the App has crashed.

Duration of data storage. The anonymous data is deleted as soon as it is no longer required.  This usually happens when the updated App no longer runs on the operating system on which the error occurred.

2 Data subject

Your rights as a data subject are comprehensively guaranteed by us. The following is a brief explanation of these rights:

2.1 Advertising objection

You may object to the future use of your data for promotional purposes at any time.

2.2 Withdrawal of consent

You may also withdraw your consent to the future use of personal data at any time. 


2.3 Other rights  

If we process personal data about you, legal provisions regarding your personal data give you the right


  • to access the data, to correct or erase the data, as well as
  • to limit the use of the data, to oppose the use of the data, and to restrict data transfer.

You also have the right to make a complaint to a Data Protection Authority about the way in which we have used your personal data.

3 Security

-weishaupt- offer you the option to encrypt the personal information you send to us. This encryption protects the confidentiality of the data exchange between you and our webserver and helps to prevent the misuse of data, e. g.  through interception. We use TLS (Transport Layer Security), which is a recognised and widely used method.
