Depending on the use and configuration, the push-fit connections on the
rear of the user interface must be occupied.
When configuring the Modbus-RTU plug:
• The jumper for activating the Modbus-RTU terminating resistor must
be inserted ex-factory.

Connection to other control units in the Control 8000
series or to a network
The connection options are presented in Chapter 11, page 14.
7.6
Connection of modules
Mains voltage
The 230-V power supply must be ensured for modules inserted at slots
1...4 via a push fit connection on the power supply module. The modules
supply voltage to one another via additional plug-in connections.
If voltage is not supplied to the module or its 230-V components
(e.g. because the plug-in connector has not been inserted), the
components assigned to this module (e.g. pumps) are not switched on.
This malfunction cannot be detected at the control unit itself as the
display and control functions are independent of the 230 V voltage.
7.7
Other connections
Other connections may need to be established, depending on the
function of the modules.
▶ Observe documents and connection diagrams of the installed modules.

Adjust
The settings, operation, commissioning, fault display and
troubleshooting of the control unit and the installed module is performed
via the remote control of the master control unit.
The settings of the modules FM-MM, FM-WM are described in the
documents of the master control unit.
The settings of the module FM-AM, are described in the documents of
the module.
▶ Observe the documents of the master control unit.
8.1
Setting the control unit address
If several control units are networked, each control unit in the network
must be given a different address. A fault is indicated on the display of
the control unit if the same address is allocated more than once.
Order of the control device addressing:
▶ First all control units that actuate a heat source.
▶ Then all control units that only actuate consumers.
Control units that actuate a heat source may not have a higher control
unit address than control units that only actuate consumers. If the
sequence of awarding the address is not observed, this leads to
control units with higher control unit addresses no longer being visible.
The address ( Fig 7, [5], page 10) is set at the control unit on the back
of the remote control.
▶ Remove the remote control.
▶ Set the control unit address (e.g. using a screwdriver).
The default setting of this control unit is pre-set to control unit address 1.
Address Description
0
Stand-alone control unit (default setting):
• Either as boiler (burner control) or as substation
(only for consumers)
Master (lead control panel):
• Always connect the outside temperature sensor to the
master.
• The master recognizes if an address has been allocated
more than once. A fault is indicated on the display of the
user interface.
• All networked control units transfer their set values to the
master. The master generates the overall set value from
these.
• Only 1 master is permitted in each network!
▶ Observe the documents of the master control unit.
1...15
Slave (control units subordinate to the master):
• The address 0 must never be assigned to a slave.
• Each address is only allocated once.
▶ Observe the documents of the master control unit.

8.2
Terminating resistances
The terminating resistances (jumper) J1 and J2 ( Figure 7, [7], [6],
page 10) are closed in the delivered condition (activated = inserted). If
a network is established via the BUS connections ( Figure 7, [2], [3],
page 10), the jumpers at the BUS nodes in the centre must be opened.
The jumpers remain closed at the first and last BUS node.
