Accenta G3?

Hi,

i've read the manual and cannot work out how to set the program modes! It says it comes with 3 program modes. I want to make program mode 3 do the following (only have 2 PIR and 1 door sensor).
1. Silent set + instant
2. Set PIR 3 (upstairs) to be disabled.

However when ever i try to enter the program mode via the instructions it bounces me out and does not respond. Can anyone talk me through the keypresses to achieve the above?
