PUMP SPEED CONTROL
The following speed control can be selected:
Variable differential pressure
∆p-v
Constant differential pressure
∆p-c
Constant speed
n=const.
Variable differential pressure (∆p-v)
This profile is suitable for use with two-line
radiator heating systems to reduce the
noise caused by the flow of liquid through
thermostatic valves. If the flow in the pipe
network decreases, the pump reduces the
head in half. This saves electrical energy by
adapting the head to the pumping capacity
requirement and lower flow velocities.
Constant differential pressure (∆p-c)
This profile is suitable for use in underfloor
heating or for piping of bigger diameters. It
is also suitable for all applications without
variable characteristics (e.g. pumps for
HW storage tank heating) and for single-
line heating systems with radiators. The
pump maintains a constant set delivery
head regardless of pumping capacity.
