A/C push button control module displays temperature in Celcius not Farenheit
 

I just had a new A/C push button control module installed in my 1996 S320 Mercedes. When I turned the unit on I noticed that the temperature was displayed in Celcius not Farenheit. Can anyone help me convert the unit to display the temperature in Farenheit? Is there a code to input on the control module?

Thanks
