How do I switch the Bluetooth function on or off on the Truma Cooler?

To switch on the Bluetooth function, press the “<>” button four times on Single Zone models and five times on Dual Zone models. You can then use the plus and minus keys to switch the Bluetooth function on/off. 

If you press “<>” and the plus key simultaneously for three seconds, you can also adjust the Bluetooth mode. You have two options here:

CLO (CLOSE): A Bluetooth connection is only possible if the QR code provided is scanned. This approach ensures that third parties are not able to change your settings on their own Truma Cooler App
OPE (OPEN): The appliance can be found via the Bluetooth function on mobile devices. This approach allows anyone in the immediate vicinity with the Truma Cooler App to control your appliance.
