Proportional pressure mode:
PP1 Lowest proportional pressure curve
PP2 Highest proportional pressure curve
The duty point of the pump will move up or down on the higher proportional pressure curve, depending on the heating demand.
The head (pressure) is reduced as the heating demand decreases and increases as the heating demand increases

Constant pressure mode:
(CP1 Lowest constant pressure curve)
(CP2 Highest constant pressure curve)
The duty point of the pump will move outwards or along a constant pressure curve, depending on the heating demand.
The head (pressure) is kept constant, regardless of the heating demand.

Fixed speed mode:
(III) Pump runs at a constant speed and consequently on a constant curve. In speed III, the pump is set to run on the Max. curve under all operating conditions. Quick venting of the pump can be obtained by setting the pump to speed III for a short period.
(II) Pump runs at a constant speed and consequently on a constant curve. In speed II, the pump is set to run on the Medium curve under all operating conditions.
(I) Pump runs at a constant speed and consequently on a constant curve. In speed I, the pump is set to run on the Min. curve under all operating conditions.

Automatic mode
In "AUTO" mode, pump power automatically increases or decreases based on system flow under certain conditions.

Night mode:
The pump works by selecting the night mode, after one hour the power turns off automatically, after two hours it will drop to a minimum between 5 and 10 watts, after seven hours the automatic mode of the pump is eliminated and restored to the original conditions.

Operating functions - control buttons.
NCE PS circulator could work:
with curves at proportional pressure
with curves at constant pressure
with curves at fixed speed
