Pos. Description Pos. Description
• Push-button for selection of pump setting
• Every time the push-button is pressed, the circulator setting is
changed
Constant Pressure I
• The duty point of the pump will move left and right along the lowest
constant-pressure curve depending on water demand in the system.
The pump head (pressure) is kept constant, irrespective of the water
demand.
III
High Fixed Speed
• Runs at a constant speed and consequently on a constant curve. In
Speed III, the pump is set on the maximum curve under all operating
conditions. Quick Vent of the pump can be obtained by setting the
pump to Speed III for a short period.
Constant Pressure II
• The duty point of the pump will move left and right along the middle
constant-pressure curve depending on water demand in the system.
The pump head (pressure) is kept constant, irrespective of the water
demand.
II
Medium Fixed Speed
• Runs at a constant speed and consequently on a constant curve. In
Speed II, the pump is set on the medium curve under all operating
conditions.
Constant Pressure III
• The duty point of the pump will move left and right along the highest
constant-pressure curve depending on water demand in the system.
The pump head (pressure) is kept constant, irrespective of the water
demand.
I
Low Fixed Speed
• Runs at a constant speed and consequently on a constant curve. In
Speed I, the pump is set on the minimum curve under all operating
conditions.
AutoAdapt (Factory Setting)
• This function controls the pump performance automatically within the
defined performance range. Automatically adjusting the pump
performance to system demands over time.
