How to set heating time for SIME 80c format Boiler?

Hi
I'm looking for the same thing but for a 80E sime, i don't know if they have the same switch but this is what i found :
The clock in the middle is for the time, the teeth around the outer edge is for the duration of the heating, if theres a three way switch in the middle then one way is off, the other is one and the middle is for the clock setting. Sorry, to be honest i'm still a little lost but maybe that might help you
