Can someone figure out my dehumidifier

[Howard]

It's a Whirlpool AD50GEUSX.

This is the closest manual I could find:

https://www.whirlpool.com/digitalassets/MLPDF/Use and Care Guide - 1317161.pdf

I checked every single manual on this page, hoping one would have the same panel:

Power button > Fan speed (bucket full, 3,2,1) > dehumidification level (1,2,3) > sleep timer, air filter sensor? > ?

I think the last one is heat. So far it seems like we're OK. Thanks!
