Why didn't my diffuser stop diffusing after clicking Timer button (ex. 1 hour)?

In order to set your diffuser to stop diffusing after 1h/4h/8h, you MUST go through all 3 steps:

1. On the remote, click desired Density
2. Click desired Interval - 30/30s , 30/60s, 30/120s
3. Click desired Timer - 1h , 4h , 8h

By only clicking Timer, the diffuser will not stop diffusing.

Do not press any other button or else settings will reset.

Once diffuser powers off/disconnects, you will need to redo steps next time diffuser turns on.
