KNX WPM
1 Installation
To prevent damage to electrical components, at least the follow-
ing precautions must be taken:
Before handling the components, touch an earthed object. It
is not sufficient to avoid touching the dangerous compo-
nents, as static electricity can result in voltage peaks of up to
10 kV and electric arcs of around 1 cm.
All materials must be stored in their original packaging for as
long as possible. If necessary, remove the PCB from the
packaging and place it in an anti-static packaging. Do not
touch the equipped side of the PCB!
Do not use static plastic bags, polystyrene or packaging
foam.
To avoid electro-static induction and discharge, the PCB
must not be passed directly from one user to the next.
The heat pump manager (HPM) must be disconnected from the
power supply / de-energised before the KNX extension can be in-
stalled.
1) Remove the "Serial Card/BMS Card" cover using a screw-
driver (see figure 2);
2) Remove the pre-punched cut-out on the cover using angled
tongs to free the opening for the 2-pin plug (see Figure 3);
3) Install the KNX expansion in the designated slot; ensure that
the KNX expansion is seated correctly (see Figure 4);
ATTENTION!
!!
The installation of the KNX expansion and the plug can prove difficult due
to the small amount of space available and the two plastic overlays; the
circuit board should be inserted diagonally and turned until the plug is in
the correct position.
4) Close the cover. Ensure that the plug is fed through the
opening in the cover (see figure 5).
2 Settings
For the communication between the KNX expansion and the
heat pump manager, settings must be made depending on the
software version.

The DCA (Device Configuration Apps) device for integration in
the ETS can be loaded under www.knx.org. Further information
and a detailed description of the configuration for the KNX ex-
pansion can be found under www.dimplex.de/wiki.

The device only guarantees a function isola-
tion between the power supply of the control-
ler and the serial bus, meaning that the
controller on which the KNX expansion is
installed must be supplied via a SELV source
