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 (Æ Fig. 7, page 33).

B Fit the grommets and connect the cables (Æ Fig. 8, page 33).

BUS connection

B Connect BUS subscribers with two BUS connectors in series

(Æ Fig. 6, page 33) or BUS subscriber [B] with one junction box [A]

in a star configuration (Æ Fig. 9, page 33).

B All LV leads must be routed separately from cables carrying mains

voltage to avoid inductive interference (minimum separation

100 mm).

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).

B Fit the cover and plug in the power supply unit supplied.

4 Commissioning

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 (Æ 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 (Æ Fig. 6, page 33) for at least 5

seconds.

The factory-set login details are restored.
