Fridge freezer controls

Question

I have a CDA 796 integrated fridge freezer which is running far too cold.

I have looked all round the fridge freezer and cannot find any controls to adjust the freezer, the fridge has controls at the top inside the fridge but this does not adjust the freezer.
The freezer is so cold that any icecream or similar products that you put in there go far too hard.

Does anyone know if there are any controls anywhere on the freezer (ie on the back or side) I havent took the freezer out of the built in unit yet as it is very heavy so thought it would be worth knowing if there is likely to be any controls before I move it
