CP: Constant Pressure
The head (pressure) is kept constant, irrespective of the heat demand.
CP1: lowest constant pressure curve
CP2: intermediate constant pressure curve
CP3: highest constant pressure curve
CP Auto Adapt: highest to lowest constant pressure curve
The Auto Adapt function enables the circulator to adjust the pump performance
automatically to the size of the system or the variations in load over time.
CC: Constant Curve
The circulator runs on a constant curve.
