First check whether the receiver was already installed in the vehicle when you carried out the initialisation. For a successful installation you will see “initialisation successful software version ############”, which is shown in the status window.
Should the receiver already be connected and you still cannot register the device, it might be that the receiver cannot connect to the mobile network. In this case, the vehicle should be moved to a location with better reception. Please carry out the initialisation once again.
2. My installed receiver is not recognised by the app!
In your app, after the entry of your vehicle (see section 3.3 in the user manual), you should see the message “initialisation carried out software version xxxxxxxxxx" in the status display. This shows you that your freeze® receiver was correctly installed and has mobile radio reception.
Please note that for successful initialisation mobile radio reception as well as the power supply to the receiver must be guaranteed.
3. When is a manual operating mode changeover possible?
Operating mode changeover (heating/ventilation/automatic) can be prescribed by the vehicle. In these cases a manual changeover is not possible.
The dfreeeze® system is connected to the parking heater via W-Bus:
- Retrofitted parking heater: Operating mode changeover is possible
- Factory-installed parking heater: dependent on vehicle
- no manual installation is possible in the app
