S line: maximum water quantity depending on the key

Hello, everyone,

i am new here and hope someone knows the following or is willing to measure it:

some models of the S-Line have besides the buttons small and large cup (1 or 2 cups each) a cup of "special coffee". What is the maximum possible amount of water for small cup, large cup and special coffee? I own an Impressa 6000 and always use "special coffee" for a large thermos cup of coffee. Now it is defective and I would like to buy a used one as a replacement. I noticed that some models (e.g. S7 and also S9 Avantgarde) do not have a button for "special coffee". I wonder if it is possible to program the "big cup" button to run through the same amount of water as the "special coffee" button.

Thanks in advance for your help!

Greetings Martin

You can program both keys as you need it, max. I think 240ml.
