PP: Proportional Pressure
The head (pressure) is reduced at falling heat demand and increased at rising heat demand.
PP1: lowest proportional pressure curve
PP2: intermediate proportional pressure curve
PP3: highest proportional pressure curve
PP Auto Adapt: highest to lowest proportional 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.
