Constant pressure auto adapt (CPAA)
The circulation pump continually regulates the flow
through the system with a great deal of freedom, to
ensure minimum pump power consumption.
The setting is intended for underfloor heating systems.
Due to optimisation to low pumping capacity, the flow
may be insufficient in certain systems.

Proportional pressure (PP)
Within a limited range, the circulation pump is permitted
to regulate its speed to an optimum system pressure.
Speed 1, 2 or 3 is selected based on maximum flow
requirement.
The setting is intended for radiator systems.
