On the "home screen", select the vehicle you want to control.
Bluetooth connections
You can download the app and pair a total of 4 smartphones
with the Bluetooth® Hub. However, only one phone can
be connected and operating the system at one time. The
first phone that enters in range of the hub will connect
automatically. After setup, your WarmUp system works even
if you disable Bluetooth on your phone. However, you must
enable Bluetooth and stay in range to be able to edit the
Pick-up times.
AC power cable alarm
We recommend that you always have Bluetooth enabled on
your phone to be able to receive an alarm if the AC power
cable is connected when the engine starts. Note:
• The phone must be connected to the Bluetooth® Hub
• Connection time is dependent on the phone model
• The DEFA app must be running in the background
• The app must have access to play the alarm sound (phone
settings) and the volume must be on
• There must be power present in the socket outlet
DEFA is not liable for any damages that may occur as a result
of moving the vehicle while the power cord is connected.
