Cos Φ(P) - meteocontrol Power Control Operating Manual

Power quality analyser and main computer are the currently supported
measurement devices (see section 6.4 Details on the PCU device
configuration -> Selection GCP source).

With this procedure, the displacement factor cos φ is used as the control
value. The requirement P is received from the selected measurement device
and is assigned to the control value with a linear equation.
