  Hello,
  i want to control the wall temperature with a powersource. Is this possible in Fluent.

  Yes. You can use expressions in the latest version(s). Take some care not to change the source too quickly and take some time to figure out the maths to calculate the source heat flux.

  Thank you. Expression Editor is recommended, i read.
  Why do i have to type in the source power in W/m^3 and not in W, is it possible to change it to W?

  Source terms are the amount added to that fluid volume.
  For example, I want to add 10 Watts to my domain. If the volume is 1m3 the source is 10W/m3: if it's 0.5m3 it'll become 20W/m3.
