6 Description and Function
6.1 Description of the pump (Fig.1.1 on pag. II)
The Wilo-Stratos PARA series high-efficiency pumps are wet-
running pumps with "

otor" (ECM) tech-
nology and integrated electronic regulation module which makes
an automatic adjustment of the pump output to variable system
loads possible.
This ensures optimum system efficiency in all operating modes
and with all loads, as well as the highest possible energy savings
on the pump side.
The regulation module has an axial design and can be found on
the motor casing (Fig. 1.1 Appendix page II item 5), with up to
three types of automatic output adjustment (depending on the
type of pump):
Table 6.1:
The essential advantages of this electronic regulation are:
Energy savings and reduced operating costs at the same
time,
Reduction of flow noise,
Fewer overflow valves required, e.g. in static heating cir-
cuits.
6.1.1 Types of differential pressure regulation
The selectable
types of regulation
are:
p-c
: The electronics maintain the differential pressure pro-
duced by the pump constant at the selected differential pres-
sure setpoint HS (up to the maximum characteristic curve)
across the entire permissible volume flow range (Fig. 3.1
Appendix page III).
p-v
: The electronics change the differential pressure set-
point value to be maintained by the pump linearly between
½Hs and Hs. The differential pressure setpoint decreases or
increases (Fig. 3.2 Appendix page III) depending on the dis-
charge rate.
6.2 Pump functions
6.2.1 Pump with operating button
The red button (Fig. 1.1 Appendix page II item 4) on the front of
the regulation module (Fig. 1.1 Appendix page II item 5) is the
central operating element, and offers three setting ranges.
Setting range (Fig. 1.1 Appendix page II position 1): Ana-
logue input 0...10 V activated. Fig. 3.3 Appendix page III
and Fig. 3.4 Appendix page III show the functions which are
linked to the analogue control signal (factory setting).

NOTE
º
The minimum and maximum setting values for the delivery height with
regulation types
p-c
and
p-v
depend on the pump type and can be
determined from the characteristic curve.
If the setpoint for the delivery height set via the red button falls below the
minimum setting value, then the pump operates at the minimum setting
Hmin for this type of regulation.
If the setpoint for the delivery height set via the red button exceeds the
maximum setting, then the pump operates at the maximum setting Hmax.
