What model is it?
I assume you mean Cunill? Ive got a Tranquilo, and Ive removed the timing board as it didnt do the job properly. From memory the timer setting went up to a bit over half a double basket worth of grounds. Thats not a fault as such, its what its designed to do.
As I said, I removed mine cause it was a pain. I now just have the on-off switch, which is much nicer.
