CONSTANT PRESSURE (CP)
Within a limited range, the circulation pump is permitted
to regulate its speed to a constant system pressure.
Speed 1, 2 or 3 is selected based on maximum flow
requirement.
The setting is intended for underfloor heating systems.

CONSTANT CURVE (CC)
The circulation pump’s speed is fixed and no regulation
takes place. Speed is selected based on maximum flow
requirement.
The setting can be used when very high flows are re-
quired.
