Granting users full control of the Series II Fridge Freezer via mobile devices, the ARB Fridge Freezer app can turn the fridge on and off, as well as manually adjust (or set via presets) the target temperature and display the target temperature, power input voltage, and fridge compressor status. Note: for Classic Series I (post-2014 models), the new transmitter and app can be used to display the temperature, input voltage, and compressor status.
