Circulator functions
All functions are activated or deactivated using the control
button, while the LED indicator shows the circulator's operating
status.
VARIABLE DIFFERENTIAL PRESSURE Dp-v
When the control knob is turned to the left, the
pressure differential value is increased in a linear
manner between 1/2 H and H of the flow rate
range allowed, up to the maximum characteristic
curve. Operating mode recommended when the
system's (pipes) pressure losses are higher than
those of the heating system. For example: radiator
systems with thermostatic valves
CONSTANT DIFFERENTIAL PRESSURE Dp-c
When the control knob is turned to the right,
the pressure differential value is kept constant
at the value set as the flow rate varies, up to
the maximum characteristic curve. Operating
mode recommended when the system's (pipes')
pressure losses are much lower than those of the
heating system. For example: Floor radiant panels
and old systems with large diameter pipes.

VENT FUNCTION
When the control knob is turned to the central
position, after a 3 second delay the vent function
is activated. This will last for 10 minutes and is
indicated by the green LED flashing quickly. During
this time interval the pump operates alternately at
high and low speed, pushing air bubbles towards
the system's vent valve. NOTE: The vent function
removes air that builds up in the pump's rotor
housing, but does not affect the heating system.
