How do I use the 1 hour cycle button?

briiv’s 1 Hour Filter Cycle allows you to set briiv running for one hour before shutting off.

To activate the 1 Hour Filter Cycle, either touch or place your hand near the ‘1’ part of the interface.

Once activated, a ‘1’ will illuminate. When the ‘1’ turns off, briiv will have completed the one-hour cycle.

While running it will disable the speed controls. 

To turn it off press the 1 hour button again until it is no longer illuminated.
