Operating range
(maximum to minimum)
Pos. Description
• Push-button for selection of pump setting
• Every time you press the push-button, the circulator setting is changed.
III
High constant speed
• The pump 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. You obtain
quick vent of the pump by setting the pump to speed III for a short period.
II
Medium constant speed
• The pump 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.
I
Low constant speed
• The pump 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 the water demand in the system. The head 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 the water demand in the system. The head 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 the water demand in the system. The head is kept constant,
irrespective of the water demand.
AUTO
ADAPT
(factory setting)
• This function controls the pump performance automatically within the defined
performance range (shaded area). AUTO
ADAPT
will adjust the pump performance to
system demands over time.
(Hold for
3 sec.)
Manual summer mode
The pump is stopped to save energy, and only the electronics are running. To avoid
liming and blocking of the pump, the pump is started every 24 hours for two minutes at a
low speed.
