I - (Minimum) the Pump runs at a constant fixed speed and therefore on
a constant curve.
II - (Medium) the Pump runs at a constant fixed speed and therefore on
a constant curve.
III - (Maximum) the Pump runs at a constant fixed speed and therefore
on a constant curve.
*Quick venting of the Pump can be achieved using speed III for a short
period.
AUTO - the power rises and falls in line with the system flow rate. *Ex
- factory setting.
(Night Mode) - the Pump reduces power automatically,
After 2 hours it drops to its minimum level (5-10 Watts).
*After 7 hours the pump reverts to its original setting.
PP1 - (Proportional Pressure 1) the duty point moves up/down on the
lowest proportional pressure curve. Head pressure is then reduced and
increased at falling and rising heating demand respectively.
PP2 - (Proportional Pressure 2) the duty point moves up/down on
thehighest proportional pressure curve. Head pressure is then reduced
and increased at falling and rising heating demand respectively.
CP1 - (Constant Pressure 1) the duty point of the Pump moves out or
in the constant pressure curve depending on heating demand. Head
pressure remains constant irrespective of heating demand.
CP2 - (Constant Pressure 2) the duty point of the Pump moves out or
in the constant pressure curve depending on heating demand. Head
pressure remains constant irrespective of heating demand.
