Decide which times of day your car should be heated
In the DEFA app you can set your departure times for each day of the week, and have your car heated and ready when you leave for and from work. In “automatic” mode, the system starts heating in time based on a reading on the outside temperature. In “manual” mode, the system will start heating according to pre-determined heating durations.

Monitor the temperature and start heating when you need it.
You can monitor the temperature outside your car in the DEFA app and turn the heating On and Off manually. You can still have a warm car, even if your plans change or the temperature suddenly plummets.

Make sure your battery is fully charged
The DEFA app also lets you monitor the status of your battery. When connected, the WarmUp system charges your battery and helps ensure that your car will start, even in severe cold.

Receive alerts if you forget to plug in or plug out
The DEFA app will alert you if you forget to unplug the cable before you start the car.
