Abstract:
The apparatus and method according to the invention comprise a controller (7) to form a control signal, which controller is arranged to receive pressure data on the CR system, and into which controller pressure reference data is set. In addition, the apparatus also comprises a module (9) to form an internal pressure reference value to replace the set pressure reference value when forming the control signal.
