Technical advice
Important information on the replacement/con-
nection 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 in-
structions of the corresponding pump! If the control
signals of the controller and the pump are not coordi-
nated, an operation is not possible.
To avoid malfunctions and severe damage to installa-
tions 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 dif-
ferent control signals, operating safety is no longer
guaranteed. Wrong control signals may cause da-
mage 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:
– Switch pump to “ON” in the manual menu (relay
test) – the pump is in operation now.
– Now switch pump to “OFF” in the manual menu –
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.
