V50, who tells me the air-conditioning automatic

Hello people, I have to out as a “depp” today. I don’t have access to the control of the automatic air conditioning system. Often the car blower thunders much too much at the start of the journey, so that I can quickly put it off again (it’s nice to say otherwise). The temperature control should actually happen with a “turn”. Instead of that, somehow you have to always click from the driver, then on the passenger to the two to regulate the temperature. With the instruction I did not really make sure at the operation. Maybe someone can give me very practical adjustment – operating tips. For example, the following questions have surfaced: Does the temperature control work without air conditioning as far as possible? Does the car blower run only in connection with climate or independently? What criteria does the blower strength of the car function depend on? How do you do that..? Thank you for your help.
