The modular control system provides the perfect means of adjustment
for boilers and wall mounted boilers equipped with a SAFe burner
control unit to ensure the operating conditions for the specific product
are satisfied.
The control unit controls an EMS oil boiler or EMS gas boiler. As an
option, a modulating boiler circulation pump can be activated via a PWM
signal or a 0...10-V interface.
The standard equipment of the control unit comprises the boiler circuit
or heating circuit with mixer and DHW heating functions. So it can be
perfectly matched with the heating system, the control unit can be
extended by up to four function modules.
No parameter settings are lost in the event of a power failure. When the

FM-CM (cascade module)
To avoid interrupting the heating circuit numbering and as the FM-CM
has no supply voltage output, it should be mounted at slot 4 (on the far
right). If several cascade modules are used, assembly should start from
the right. With several control units, the FM-CM in the master control unit
must be installed with the address 0.
FM-RM
The module can only be installed at slot C.
FM-MW
Each control unit can only support 2 DHW heating systems, e.g. DHW
heating via the central module (ZM) and via the FM-MW.

3.1.1 Notice regarding fitted modules
The additional modules can be installed in any free slot 1...4. In doing so,
make sure that the power supply leads from module to module. We
recommend that you insert the modules in order from left to right to
ensure the heating circuits are logically numbered.
When using the following modules, it is advisable to mount them at
specific slots.
FM-AM
The module only affects the control unit in which it is fitted. If the module
is installed in the master control unit with address 0, it is effective for the
connected boiler(s). If the module is fitted in a substation, it will respond
to the heat requirement issued by that substation.
FM-SI
Due to the length of the SI connecting lead, the safety module should be
mounted at slot 1.

Installation
Note the following when making electrical connections:
• All electrical connections, safety measures and safety devices must
be implemented by an approved contractor, taking into account the
standards and guidelines that are applicable in each case as well as
the local regulations.
• Establish electrical connection as a fixed connection in accordance
with local/national regulations.
• Electrical connections are established as specified in the connection
diagram for the control unit and the module.
To prevent inductive influences:
▶ Make sure all low-voltage cables are routed separately to mains
voltage cables (min. clearance 100 mm).
• When installing the devices, ensure an earth connection is present.
• Do not exceed the total current stated on the data plate, and the
partial currents for each safety switch and connection.
• Before opening the control unit, disconnect all poles of the control
unit and secure against unintentional reconnection.
• Incorrect attempts to make connections under voltage may damage
the control unit beyond repair and lead to dangerous electric shocks.
▶ Establish electrical connections as specified in the connection
diagram of the control unit and the local conditions.
5.4 User interface connections (HMI)
5.5 Connecting the heat source to the control unit
5.5.1 Connection to the SAFe
WARNING:
Danger to life due to flue gas at the installation location!
With older SAFe software versions (not permitted here), the heat source
may start automatically in unfavourable circumstances!
Unfavourable scenario: connection between heat source (with old SAFe)
and ZM5313 is interrupted.
▶ Only use heat sources with SAFe with software version ≥ Table 3.
If a boiler with SAFe burner control unit is being connected, the EMS
connection has no function!
SAFe heat sources are heat sources that are equipped with a SAFe
(burner control unit) for burner control. The SAFe is directly connected
to the higher level plant control system (e.g. Control CC 8313).
As the software version of the connected heat source determines
whether or not the control functions correctly, the software version of
the SAFe must be checked directly following connection.
Connections:
• On the ZM5313 central module at the BUS SAFe and mains
SAFe terminals
• On the SAFe at the BUS and mains SAFe terminals.

Installation
5.5.2 Connection to a EMS heat source
NOTICE:
Material damage due to incorrect connection!
When connecting EMS heat sources:
▶ Remove jumper at the external interlock terminal.
▶ Only connect safety equipment directly at the EMS boiler.
EMS heat sources have their own basic control (control panel,
e.g. BC10). The SAFe is connected to the control of the heat source.
If a plant control system is installed, it is superordinate to the control of
the heat source.
The user interface of the control unit and the basic control
(control panel) of the heat source are directly connected.
Connections:
• On the back of the user interface at the EMS terminals
( Fig. 4, [4], page 9) with
• Basic control of the heat source at the (EMS)-BUS terminals
When connecting a boiler via the EMS terminals:
▶ Remove jumper at the external interlock terminal.
The external interlock connection has no function in conjunction
with EMS boilers!
▶ External safety equipment that lead to blocking must be connected
to the EMS boiler directly.
5.5.3 Connection via the Modbus interface
For heat sources (e.g. CHP module) that are connected via the
Modbus-RTU ( Fig. 4, [3], page 9):
▶ Connect communications cable to the Modbus-RTU connection.
▶ Consider connection to the heat source.
5.8 Connection of safety equipment and the FM-SI
module
SAFe heat source
If a boiler with SAFe burner control unit is being connected, the EMS
connection has no function!
▶ Connect safety equipment or a condensates neutraliser at the FM-SI
module.
▶ Close unused SI inputs with a jumper.
When using a condensate neutraliser:
▶ Connect condensate neutraliser to SI1 input.
EMS heat source
Use of the FM-SI with EMS heat sources is not permitted if the heat
source is connected via the EMS terminal ( Fig. 4, [4], page 9).
▶ Connect external safety equipment directly to the control of the heat
source (terminal SI 17, 18).
▶ Always connect safety equipment that shuts down the heat source to
the basic control of the heat source (EMS control).
If EMS heat source was selected in the setting:
▶ Open the safety chain (terminal SI 17, 18) at the ZM5313
without fail.
▶ Do not install a jumper!
If safety equipment is connected, a jumper is installed or a Sl module is
inserted at the ZM5313, a fault display is generated.
To avoid vagabond voltages:
▶ Only connect cable shield to one control unit!
5.6 Connection to other control units in the 8000 series
or to a network
The connection options are presented in Chapter 16.1, page 37.
5.7 Connection of modules
Mains voltage
The 230 V power supply must be ensured for modules fitted at slots
1…4 via a plug-in connector 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 are not switched on (e.g. pumps).
This malfunction cannot be detected at the user interface itself as the
display and control functions are independent of the 230 V voltage.
5.9 Remote control
If a remote control is provided for the heating circuit, this must be
connected to the BF terminals. The remote control is assigned to the
corresponding heating circuit via the coding switch in the remote
control.
5.10 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!
UM10 function module
A UM10 must not be installed in a heating system if the heat source is
activated via the ZM5313. The ZM5313 takes over the UM10
functionality.
