Important information on the replacement/
connection of controllers and speed controlled
high-efficiency pumps
In addition to the power supply cable (230 V), speed
controlled high-efficiency pumps call for a separate
cable for the transmission of the control signal.
The most common control signals are 0-10 V and
pulse-width modulated signals (PWM) of proportional
and inverted type.
The type of signal is specified in the operating
instructions of the corresponding pump If the
control signals of the controller and the pump are not
coordinated, an operation is not possible.
To avoid malfunctions and severe damage to
installations with speed controlled high-efficiency
pumps, the following must be observed:
– The pump must only be replaced with a pump with
identical control signal
− The controller must only be replaced with a
controller with identical control signal
− When combining a pump and a controller with
different control signals, operating safety is no
longer guaranteed. Wrong control signals may
cause damage to the installation and endanger
health
− The following functional test has to be carried out
when putting the controller or pump into operation
and when replacing them:
1. Switch pump to "ON" in the manual menu (relay
test) –the pump is in operation now.
2. Now switch the pump to "OFF" – the pump is no
longer in operation.
– Work on electrical installations must only be carried
out by a qualified electrician.
– Always disconnect the power supply before starting
work on electrical components.
– If not stated otherwise, all work and settings must
only be carried out by a trained tradesman.
– Under working conditions, high-efficiency pumps
are almost silent. Malfunctions caused by airlocks
could be confounded with a pump defect. This has
to be taken into account when carrying out the
functional test
The installation and operating instructions that come
with the pump, controller and station have to be read
in their entirety before installation and initial operation.
The instructions have to remain with the user of the
system. Claims of any kind due to damages caused
by the nonobservance of the instructions or incorrect
use cannot be accepted.

1. Remove the station (1) from the insulation. Pull off
the front insulation (4) and the insertion block (2).
2. Determine the position of the station on the
wall and provide two 10 mm bore holes. Use rear
insulation as drilling jig.
3. Insert the included dowels into the bore holes.
