climatronic - intake temprature

[Turbomier]

anyone knows how to activate the intake temperature?
i know how to get in the program with the climatronic airco.
but the numbers are locked and they stay on 0.0
if i turn or push any button it's tays on 0.0 or it goes out of the program back to airco.

so anyone knows what to do next, what to do to see the true intake temp.
and, are there other things i can see via the climatronic?

Thx
