Installation / Assembly

  • How can I test the app before buying it?

    Please contact us.

    You can reach our support team at: dfreeeze [at] digades.de

  • My parking heater is not reacting. Why is that?

    First, please check whether your receiver was already installed in the vehicle when you performed the initialisation.

    Initialisation was successful if the status display shows the message “Initialisation successful software version ############”.

    If the receiver has already been connected but you are still not receiving the message, that may be because the receiver cannot connect to the mobile phone network. In this case you should move your vehicle to a location with better reception. Then perform the initialisation again.

  • The app does not recognise my installed receiver!

    Once you have set up your vehicle in the app (see section 3.3 in the user manual), the status display should show the following message: “Initialisation performed software version xxxxxxxxxx”. This indicates that your dfreeeze receiver was installed correctly and has mobile phone reception.

    Please note that initialisation can only be successful if the receiver has mobile phone reception and a power supply.
