How do I set the 1 hour cycle on Briiv 2?

Briiv 2’s 1 Hour Filter Cycle allows you to set the unit running on maximum speed for one hour before it automatically returns to its prior setting.

To activate the 1 Hour Filter Cycle, touch the large dot below the speed indicator dots.

Once activated, Briiv 2 will run at full speed for 60 minutes and then return to its previous setting.
