Why does D11 light when I have defined only D9?

[bobcov]

<div> pinMode (CONTROLLINO_D9, OUTPUT);</div><div>

and

digitalWrite (CONTROLLINO_D9, HIGH);

delay(100);

digitalWrite (CONTROLLINO_D9, LOW);

delay(100);

makes D11 light, but not D9. Is that a fault?

Is there a diagnostic sketch somewhere to test everything?
