Electrical wiring
The connection cables for the power supply and
the connection to the KNX-BUS must be provided
by the customer.
The connection to KNX/EIB is established via a
bus connection terminal.
An IP interface requires additional operating
voltage for operation. Also refer to the manufactur-
er's documentation for this.
Only carry out the work described below when
the KNX module is supplied with voltage! If you
carry out the work described below without the
KNX module being supplied with power, the
heat pump cannot be commissioned.
Connect the terminals [3 & 4] of the already
installed KNX module with the on-site power
supply and the KNX-BUS. Now remove the RJ45
plug from the I/O module and plug it into the free
interface on the KNX module (labelled Touch Dis-
play [1]). Now take the free end of the network
cable attached to the interface [2] labelled I/O
module and plug it into the freed up socket in the
I/O module. (see Fig. 2 or Fig. 3)
