Not a KDS 20, only a KDS 19
Actually that's a KDS-19.
The KDS 20 used a different Air Diffuser. It was a metal one in the right corner compared to the plastic one.
Also, if you look at the buttons, there's missing another button: Energy Saver Dry - Heat Off.
One more thing, the panels are different.
The 20 series and above came with interchangable panels. We had the Custom 20 Series with interchangable panels, different air diffuser.
Also, the Superba 19 series had a Light Wash. and No Heat Dry Only by looking at the Air Difusser.
I'm sure Stevet could add more then I did on this model.
