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.

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.

9.4 Heating circuit data

The heating circuit on the central module (PK, SR, FZ) can be used either as a heating circuit with mixer or as a boiler circuit. If a system component is used in a function, the other system components can no longer be used for the other function.

Example: if SR is used as the mixing valve for the boiler circuit, PK cannot be used for a heating circuit without mixer.

When used as a heating circuit, this is displayed as heating circuit 00.

Display of heating circuits

The designation assigned to the heating circuits depends on the slot of the heating circuit module. The heating circuits are numbered according to the sequence of slots. This means that the heating circuits at slot 1 are displayed as heating circuit 01 and 02. The heating circuits at slot 2 are displayed as 03 and 04. If a different module is inserted at a slot, these heating circuit numbers are omitted.

If a name has been assigned to the heating circuit, this is displayed.

Only the heating circuits that are available via modules are displayed. The heating circuit symbols turn grey if heating circuits are available but not active. If heating circuits are available and active, the heating circuit symbols are displayed normally in white.

This means that walls with a high thermal storage capacity (Heavy) respond slowly to changes in outside temperature. Walls made of bricks, for example, take longer to reach the outside temperature. This means they store up heat which keeps the house warmer for longer at low outside temperatures.

With a low thermal storage capacity (Light), the room to be heated quickly responds to changes in outside temperature. A house made of wood frame walls, for example, has no storage mass, which means that only the insulation in the walls influences the specific heat energy demand of the building.

10.2.2 Insulation standard

The specifications for the Insulation standard refer to the insulation capacity (heat transfer) of the wall construction material. This means that walls with thick thermal insulation (Good) respond slowly to changes in outside temperature. For example, it takes longer for walls with thick thermal insulation to reach their storage capacity limit, and therefore for this to be noticeable. For the same reason, brick walls with thick thermal insulation stay cool or longer. This means they store up heat which keeps the house warmer for longer at low outside temperatures.

Underfloor heating system

In buildings with underfloor heating systems, the Insulation standard should be set to Good. The underfloor heating system (heat-up time of the floor construction) has a similar inertia to thick thermal insulation in a house.

Control 8313 – 6720859567 (2017/03)

Settings

Examples of settings to be used when setting the heating system for the first time are shown below.

• House 1: brick walls with 20 cm thermal insulation – Building: Heavy – Insulation standard: Good

• House 2: prefabricated house made of wood frame walls and 20 cm thermal insulation

x Input voltage in V (default setting) y Set boiler water temperature in °C

When programming a curve with a negative slope (e.g. 0 V = 90 °C) make sure that all 0...10 V inputs of a control unit are connected. An open input corresponds to 0 V and thus to a heat requirement of e.g. 90 °C.

10.3.2 Output 0...10 V

If Output has been selected for the 0...10 V input, the boiler responds exclusively to this requirement. This means the control unit will not take any further requirements into account (e.g. domestic hot water, heating circuits).

If you selected Output for the 0...10 V input, you can adapt the curve, if required, to the external output.

The start value (start-up point) of the curve is set to 0.6 V with a positive curve ( Fig. 16).

10.3 External heat requirement

An external heat requirement can be applied at the terminals WA1/2/3 with this function.

Several functions are available for selection:

• Off/On of the heat requirement via the terminals WA1 and 3 – Contacts WA1 and WA3 open = heat requirement Off – Contacts WA1 and WA3 closed = heat requirement On

When a heat requirement exists, the boiler runs until it reaches the maximum possible temperature (Maximum shutdown temperature).

• Temperature-based control or output control via 0...10 V signal via WA1/2

– Temperature-based control ( Chapter 10.3.1, page 31) – Output-based control ( Chapter 10.3.2, page 31).

11.1 General settings regarding boiler parameters

11.1.1 Setting up the pump function

The terminals of the PWM signal are not working.

Activation of the boiler circuit pump via 0...10 V

The boiler circulation pump can be connected in modulating operation via a 0...10 V output (PK MOD).

▶ For the minimum and maximum voltage values of the pump, refer to

the specifications of the pump manufacturer.

▶ Setting the Voltage for min. flow temp and Voltage for max. flow

temp parameters.

0...10 V According to temperature difference

The pump modulation is activated so as to achieve the set temperature differential between the system flow/differential sensor and boiler water temperature sensor.

Recommendation with low loss header: set 0...10 V Output.

11.2 Maximum shutdown temperature

With EMS boilers, the maximum cut-off temperature is specified by the SAFe of the heat source, which is connected to the control unit. The maximum cut-off temperature can only be reduced in the control unit menu.

The maximum cut-off temperature is set in the Boiler characteristics menu under the menu item Maximum shutdown temperature.

If the heat source does not reach the maximum cut-off temperature that has been entered, it may also be limited by external parameters. This could be for example:

• a control unit in the boiler used

• a burner control unit (SAFe) in the heat source used

• a 0...10 V signal of an external setpoint value

11.3 Information on the FM-SI module

When several items of safety equipment connected to the safety module are triggered, only one fault display appears. Only the input with the lowest number appears as fault display. If additional safety equipment has been triggered, these are displayed in the Monitor data menu.

Example

The safety equipment at FM-SI1 and FM-SI4 has been triggered. Only the triggering of connection FM-SI1 appears in the display. Both of the triggered connections can be seen in the Monitor data menu.

0...10 V according to output

The 0...10 V signal is subject to the currently required burner output:

• 100 % burner output = 10 V (maximum pump modulation)

• Minimum burner output = 0 V (minimum pump modulation)

Recommendation: install heat exchanger for system separation.

The boiler circuit pump must be sized to suit the heating system hydraulics to ensure perfect operation:

DANGER:

Danger to life due to electric shock!

Before opening the device:

▶ Isolate the mains voltage. ▶ Secure against unintentional reconnection.

Checking fault: ▶ Remove sensor terminals. ▶ Check the resistance at the temperature sensor cable ends

using an ohmmeter.

▶ Check the temperature at the temperature sensor with

a thermometer.

The following tables show whether the temperature and pressure drop value correspond.

The sensor tolerance for all curves is ± 3 % at 25 °C.
