Pos. Description
• Push-button for selection of pump setting
• Every time the push-button is pressed, the circulator setting is changed
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.
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.
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.
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.
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.
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.
AutoADAPT (Factory Setting)
• This function controls the pump performance automatically within the dened performance range
(shaded area). AutoADAPT will adjust the pump performance to system demands over time.
