Pre-assembling the grommets and connecting the cables
B Open out the grommets to match the cable diameter and make an
incision on one side ( Fig. 7, page 33).
B Fit the grommets and connect the cables (
BUS connection
B Connect BUS subscribers with two BUS connectors in series
( Fig. 6, page 33) or BUS subscriber [B] with one junction box [A]
in a star configuration ( Fig. 9, page 33).
If the maximum cable length of the BUS connection
between all BUS subscribers is exceeded, the system
cannot be commissioned.

B In case of external inductive interference, shield the cables.
This ensures that the cables are shielded from external interference
(e.g. heavy current cables, overhead wires, transformer stations,
radio and television set, amateur radio stations, microwave ovens
etc).

Commissioning

During commissioning, the LED on the module
illuminates in red if neither the BUS nor the LAN
connection is made.
The router must be configured as follows:
• DHCP enabled
• Ports 5222 and 5223 not blocked
• Free IP address available
• Address filtering (MAC filter) matched to the module.
The module automatically obtains an IP address from the router. The
name and address of the target server are stored in the standard settings
of the module. If there is an internet connection, the module
automatically logs into the Junkers-Server.
The router does not necessarily have to be connected to the internet.
The module can also be operated using the local network only. If this is
the case, access to the heating system via the internet or automatic
updates of the module software are not possible.
The first time the JunkersHome App starts, you will be prompted to
enter the factory-set login name and password. These login details are
printed on the module data plate.

Testing the connection (with heating circuit 1 logged on)
You can check whether the module is communicating correctly with the
heating system.
B Press the RESET button ( Fig. 6, page 33)briefly in order to change
the operating mode for heating circuit 1 at the controller.
The controller display shows the modified operating mode (heating
or economy ).
B To conclude the connection test, reinstate the required operating
mode.
Resetting personal settings
If you have forgotten your personalised login name or password:
B Hold down the RESET button (
seconds.
The factory-set login details are restored.
