5.4 Electrical connection! DANGER
Risk of fatal injury due to electric shock.
− For electrical installation, you are required
to observe the relevant electrotechnicalregulations of the country of use as well as
the regulations of the local power
suppliers. Therefore, such work must be
performed by trained and experienced
personnel.
− The terminals 20, 22, 25 and 28 allow the
integration of safety equipment which havea direct influence on individual electric
actuators and pumps. If this is not the case,connect a jumper from terminal 18 toterminals 20, 22, 25 and 28.
Î Do not connect ELV cables (according to
VDE 0100) to these terminals.
Î Before performing any work on the terminals, disconnect the voltage supply
from the heating controller.

kept when the lines are installed in acabinet.
Î Install the lines for digital signals (buslines) and analog signals (sensor lines,
analog outputs) separately and awayfrom each other.
Î In plants with a high electromagnetic
noise level, we recommend using shielded cables for the analog signals.
Î Ground the shield at one side, either at
the control cabinet inlet or outlet, using
the largest possible cross-section. Connect the central grounding point and thePE grounding conductor with a cablewith at least 10 mm² wire cross-section
using the shortest route.
Î Inductances in the control cabinet, e.g.
contactor coils, must be equipped withsuitable interference suppressors (RC elements).
Î Shield control cabinet elements with highfield strength, e.g. transformers or frequency converters, with separators providing a good connection to the PE
grounding conductor.
Î Use wires with wire cross-sections as listed in Table 5-1 for terminals.

Notes on electric wiring
Î Install the 230 V power supply lines andthe signal lines separately and awayfrom each other.
Î To increase immunity, keep a minimum
distance of 10 cm between the lines.
Make sure the minimum distance is also

Installation

Overvoltage protection

Wiring of a room panel− If signal lines are installed outside buildings or over large distances, make sureappropriate surge or overvoltage protection measures are taken. Such measures
are indispensable for bus lines.

Î Connect as shown in Fig. 5-4.

− The shield of signal lines installed outsidebuildings must have current conducting
capacity and must be grounded on bothsides.

− 0 to 10 V control output: use cables witha minimum wire cross-section of
0.5 mm².

− Surge diverters must be installed at thecontrol cabinet inlet.
Connecting the heating controller
Î If the controller housing and the basehave not yet been separated: unscrew
the screws on the bottom left and top
right of the housing to open it to connect
the wiring.
Î To feed through cables, make holes in themarked locations at the top, bottom orback of the base of the housing and fit
suitable grommets or cable glands.
Î For wall mounting: ensure that the lines
are not subject to torsion or bending by
taking suitable precautions, e.g. a cable
duct, before inserting them into the base.
Î Connect as shown in Fig. 5-2 orFig. 5-3.

Connecting the water flow sensor
Î Connect as shown in Fig. 5-5.
Connecting actuators− Three-step or on/off outputs: connect cables with at least 1.5 mm² suitable fordamp locations to the terminals of thecontroller output. We recommend checking the operating direction on start-up.
Connecting pumps
Connect all cables with a minimum 1.5 mm²
wire cross-section to the terminals of theheating controller as illustrated in the wiring
diagram.
Note
The electric actuators and pumps are not automatically supplied with a voltage by thecontroller. They can be connected over terminals 20, 22, 25 and 28 to an external voltage supply. For an internal power supply,
place a jumper from terminal 18 to terminals
20, 22, 25 and 28.

Connecting sensors
The wire cross-section of the sensor cables
must not be smaller than 0.5 mm².

5-4EB 5573-1 EN

Installation! DANGER
Risk of fatal injury as a result of failing toobserve the permissible touch voltage.
Separation of the circuits is absolutely essential when SELV equipment is connected toterminals 20, 22, 25 and 28 as this equipment has a different intended use of the supply voltage than specified in the technicaldata (230 V AC).
The creepage and clearance present in thebase and controller do not guarantee the required dielectric strength and the safe separation of the 230 V supply voltage and theother circuits.
Î Take appropriate safety precautions (e.g.
by using coupling relays for the controlof electric actuators operated with 24 V
or for ELV fault signaling contacts).
Î Only connect 230 V equipment.

As described in the error list, sensor failures are indicated by the 'Sensor failure' error message in the error level. For detailed information, exit the error level and view the different
temperature values in the information level: each sensor icon displayed together with threedashes instead of the measured value indicates a defective sensor. The following list explains
how the controller responds to the failure of the different sensors.
− Outdoor sensor AF1: when the outdoor sensor fails, the controller uses a flow temperature set point of 50 °C or the 'Max. flow temperature' when the max. flow temperature(PA1, 2 -> P07) is lower than 50 °C. With the setting CO1, 2 -> F05 - 1 (underfloor
heating), the flow temperature set point is 30 °C in the event of a malfunction.
− Flow sensor(s) in heating circuit(s): when the flow sensors in the heating circuits are defective, the associated valve moves to 30 % travel. DHW heating which use such a sensor
to measure the charging temperature is suspended.
− Flow sensors in the DHW circuit with control valve: when the flow sensor VF4 fails, thecontroller behaves as if VF4 has not been configured. As soon as the control of thecharging temperature becomes impossible (VF2 defective), the associated valve is closed.
− Return flow sensors RüF1/2: when the return flow sensor fails, the controller continues
operation without return flow temperature limitation.
− Room sensors RF1/2: when the room sensor fails, the controller uses the settings for operation without room sensor. The controller, for example switches from optimizing mode
to reduced operation. The adaptation mode is canceled. The last determined heating
characteristic remains unchanged.
− Storage tank sensors SF1/2: when one of the two sensors fails, the storage tank is nolonger charged (exception: solar system).
− Solar circuit sensors SF, VF, RüF: when one of the two sensors fails, the storage tank inthe solar circuit is no longer charged.

Outdoor-temperature-compensated control

When outdoor-temperature-compensated control is used, the flow temperature is controlled
based on the outdoor temperature. The heating characteristic in the controller defines theflow temperature set point as a function of the outdoor temperature (see Fig. 16-2). The outdoor temperature required for outdoor-temperature-compensated control can either be measured at an outdoor sensor or received over the 0 to 10 V input.

Basically, the following rule applies: a decrease in the outdoor temperature causes the flow
temperature to increase in order to keep the room temperature constant. By varying the gradient and level parameters, you can adapt the characteristic to your individual requirements:

Outside the times-of-use, reduced set points are used for control: the reduced flow set point iscalculated as the difference between the adjusted values for 'Day set point' (rated room temperature) and 'Night set point' (reduced room temperature). The 'Max. flow temperature' and'Min. flow temperature' parameters mark the upper and lower limits of the flow temperature.
A separate gradient characteristic can be selected for the limitation of the return flow temperature.
Examples for adjusting the characteristic:− Old building, radiator design 90/70:

Gradient approx. 1.8− New building, radiator design 70/55:

Gradient approx. 1.4− New building, radiator design 55/45:

Gradient approx. 1.0− Underfloor heating depending on arrangement:

Gradient smaller than <0.5

NoteParticularly for control operation without room sensor, the room temperatures set for day('Day set point') and night ('Night set point') only become effective satisfactorily when theheating characteristic has been adapted to the building/heating surface layout.

Appendix A (configuration instructions)16.2.3

Underfloor heating/drying of jointless floors

Using function block setting CO1, 2 -> F05 - 1, the respective heating circuit is configured as
an underfloor heating circuit. In doing so, the controller at first only limits the value ranges of
the heating characteristic gradient and the maximum flow temperature in PA1, 2 parameterlevels:− Value range of the gradient: 0.2 to 1.0− Value range of the maximum flow temperature: 5 to 50 °C
Furthermore, it is possible to set a Boost between 0.0 to 50 °C, which is additionally taken
into account when there is a heat demand for the underfloor heating circuit of an upstream
control circuit. The Drying of jointless floors function can be activated afterwards. The function block parameters (starting with the 'Start temperature') determine the drying process: thefirst heating up phase starts at the entered 'Start temperature', which has a flow temperatureof 25 °C in its default setting. The start temperature is constantly regulated for the days entered in 'Hold (days)'. Afterwards, this temperature is raised by the value entered in 'Temp.
rise/day' within 24 hours, i.e. the default setting causes the flow temperature set point to riseto 30 °C 24 hours after the holding phase. If the maximum temperature is reached, it is kept
constant for the number of days entered in 'Hold (days)'. The 'Temp. reduction/day' parameter determines the temperature reduction downwards. If the 'Temp. reduction/day' is set to 0,
the temperature maintaining phase moves directly to automatic mode. If the function blockparameter 'Start temperature' is set to 25 °C and 'Temp. rise/day' to 0.0 °C, the drying
functions runs as specified in Part 4 of DIN EN 1264: the drying of jointless floors function

the controller switches to the maximum adjusted temperature. The further process remains unchanged. The drying of jointless floors function is activated using the adjusted 'Start temperature' by changing the setting 'Stop' to 'Start'. 'Start' is displayed when the drying function starts. The restarting stages 'Build-up', 'Hold' (holding the maximum temperature) and'Reduction' can be be selected to continue an interrupted drying process. The course of thedrying process can be monitored in the operating level by reading the measured data of theassociated heating circuit.

The drying process has been successfully completed when 'Done' is displayed. This disappears from the display after resetting the display to Stop in CO1, 2 -> F05 or after the failureof the supply voltage. If a power failure occurs while the drying process is in progress, thedrying process continues afterwards exactly at the point at which it was interrupted when the
power is reconnected. In systems in which the drying function had to be interrupted due to
DHW heating (e.g. system Anl 2.1), storage tank charging does not occur while the drying
function is active, provided it is not used for frost protection of the storage tank.

Appendix A (configuration instructions)16.2.4.1 Outdoor temperature for continuous day mode
If a heating circuit is in night mode (automatic mode, ), this circuit is switched to day mode
whenever the outdoor temperature falls below 'Outdoor temperature for continuous day
mode'. The night mode restarts after the outdoor temperature rises above the limit (plus
0.5 °C hysteresis).
This function prevents the building from cooling down excessively outside the times-of-use
when low outdoor temperatures occur. The transition towards day mode can be configured to
be variable depending on the outdoor temperature.

Buffer tank systems Anl 16.x

A heating characteristic based on a gradient or four entered points can be set in PA1 for the
buffer tanks in systems Anl 16.x. A buffer tank set point for day operation and a buffer tankset point for night operation can be set without outdoor sensors in the customer level. An external demand transmitted from secondary controlled heating circuits, DHW circuit or an external request (over a 0 to 10 V or binary signal) can override the current buffer tank set
point. The maximum demand is indicated as the buffer tank set point for SF1. If the temperature falls below the buffer tank set point at SF1, charging of the buffer tank is started.
The set point of the charging temperature is determined by the 'Minimum set point to charge
buffer tank' parameter setting in the PA1 level. The automatic adaptation ('AUTO' setting)causes the set point of the charging temperature to always be above the current buffer tankset point by the value entered in 'Charging temperature boost'. Every other value entered in'Minimum set point to charge buffer tank' is used as the minimum set point for the charging
temperature which first starts to be variable at higher buffer tank set points. When a return
flow temperature sensor RüF1 is used, the charging pump SLP (CO1 -> F22 - 1) is first released to avoid cold charging when the temperature measured at RüF1 has reached thesame temperature measured at SF1. The 'Stop charging of the buffer tank' parameter(PA1 -> P17, default = AUTO) determines under which conditions the charging of the buffertank is stopped. The automatic adaptation ('AUTO' setting) causes the buffer tank charging
to be stopped when the temperature in the buffer tank reaches the 'Buffer tank set point'. Every other value entered for 'Stop charging of the buffer tank' is rated as a fixed switch-off
temperature for the buffer tank charging. When SF2 (CO1 -> F06 - 1) is configured, SF2 isalways used to stop the charging of the buffer tank. The storage tank charging pump is notswitched off until the lag time (entered 'Valve transit time Ty' for Rk1 multiplied by 'Lag timeof charging pump') has elapsed. An activated setting CO1 -> F27 - 1 (discharging protection) causes the charging to be stopped when the charging temperature does not reach its set
point even though the valve is fully open or it falls below the temperature measured at SF1and does not rise again. Charging with the valve fully open is stopped after one hour at thelatest. In such cases, 'Operation: discharging protection' is displayed with the measured values in HC1 for the next 30 minutes.
The CO1 -> F27 - 1 setting causes a 2 °C higher charging set point to be calculated. The following then applies:
Charging set point = Set point at SF1 + 'Charging temperature boost' + 2 °C
The operation of the feeder pump UP1 is either determined by the ZP time schedule orprompted over an external demand. For systems with downstream control circuits, either only
this external demand or the demand of the downstream control circuits causes the feeder

The pump UP2 of the solid fuel boiler circuit in systems Anl 16.2 and 16.4 starts to run when
the temperature reaches 'Start temperature for boiler pump' at VF2. The boiler pump is
switched off again when the temperature at VF2 falls below the temperature T = 'Start temperature for boiler pump' – 'Boiler pump hysteresis'.
In systems Anl 16.3, 16.4 and 16.6, a solar circuit is integrated, which uses storage tanksensor SF2 for control. The collector circuit pump CP is activated when the temperature at thecollector sensor RüF2 is higher than that at storage tank sensor SF2 by the value entered in'Solar circuit pump ON'. It is deactivated when the temperature difference falls below thevalve entered in 'Solar circuit pump OFF', when the temperature at the storage tank sensor
SF2 reaches 'Max. storage tank temperature' or when the collector temperature rises above
120 °C. The temperature-based adaptation of the delivery rate of the charging pump SLP
can be implemented using a 0 to 10 V signal. It can be reversed, if required.
Note
The buffer tank control circuit is deactivated as described in Chapter 16.2.4.1. When predefined gradients of heating characteristic (CO1 -> F11 - 0) are used, night mode is not possible in the buffer tank control circuit. In contrast to an active four-point characteristic(CO1 -> F11 - 1): in this case, a four-point characteristic exists for day and night modes.

If the mean daytime temperature exceeds the 'Boost' on the number of successive days set in 'No. days until activation',summer mode is activated on the following day. This means that the valves in all heating circuits are closed and the circulation pumps are switched off after t = 2 x valve transit time. If

16.2.9Optimization

This function requires the use of a room sensor. Depending on the building characteristics,
the controller determines and adapts the required advance heating time (maximum 8 hours)
to ensure that the desired 'Day set point' (rated room temperature) has been reached in thereference room when the time-of-use starts. During the advance heating period, the controller
heats with the max. flow temperature. This temperature is built up in steps of 10 °C. As soon
as the 'Day set point' has been reached, outdoor-temperature-compensated control is activated.
Depending on the room sensor, the controller switches off the heating system up to one hour
before the time-of-use ends. The controller chooses the deactivation time such that the room
temperature does not drop significantly below the desired value until the time-of-use ends.
During the advance heating period and the premature deactivation of the heating system, theor icon blinks on the display.
Outside the times-of-use, the controller monitors the 'Night set point' (reduced room temperature). When the temperature falls below the night set point, the controller heats with the max.
flow temperature until the measured room temperature exceeds the adjusted value by 1 °C.
Note− Direct sunshine can cause the room temperature to increase and thus result in the premature deactivation of the heating system.
− When the room temperature decreases while the heating system is shortly outside its timesof-use, this can prematurely cause the controller to heat up to the 'Day set point'.

16.2.10 Flash adaptation
To ensure that the controller reacts immediately to room temperature deviations during rated
or reduced operation, the function block setting CO1, 2 -> F09 - 1 needs to be made. The
heating is then always switched off as soon as the room temperature exceeds the 'Day set
point' or 'Night set point' by 2 °C.
Heating first starts again when the room has cooled off and the room temperature is 1 °C
above the set point. The flow temperature set point is corrected if the 'Cycle time' or 'KP(gain)' are set to a value other than 0. The 'Cycle time' determines the intervals at which theflow temperature set point is corrected by 1 °C. A 'KP (gain)' set to a value other than 0causes a direct increase/decrease in flow temperature set point when a sudden deviation inroom temperature arises. A 'KP (gain)' setting of 10.0 is recommended.
Note− Cooling loads, such as drafts or open windows, affect the control process.

Fig. 16-4: Schematics of a storage tank system

The controller begins charging the storage tank when the water temperature measured atstorage tank sensor SF1 falls below the 'DHW temperature set point' by 0.1 °C. If the flow
temperature in the system exceeds the desired charging temperature, the controller tries to reduce the flow temperature in the heating circuit for up to three minutes before the storagetank charging pump is activated. When there is no heating operation or when the flow temperature in the system is lower, the storage tank charging pump is switched on immediately.
If the function CO4 -> F15 - 1 (SLP ON depending on return flow temperature) is activated,
the primary valve is opened without simultaneously operating the storage tank charging
pump. The storage tank charging pump is first switched on when the primary return flow
temperature has reached the temperature currently measured at storage tank sensor SF1.
This function enables storage tank charging when the heating system is switched off, e.g. insummer mode, without cooling down the storage tank first by filling it with cold flow water.
The storage tank charging pump does not start operation before a sufficiently high temperature has been reached at the heat exchanger. An activated setting CO4 -> F27 - 1 (discharging protection) causes the charging to be stopped when the charging temperature does notreach its set point even though the valve is fully open or it falls below the temperature measured at SF1 and does not rise again. Charging with the valve fully open is stopped after one
hour at the latest. In such cases, 'Operation: discharging protection' is displayed with themeasured values in the DHW circuit for the next 30 minutes.

Appendix A (configuration instructions)

Note
The 'DHW temperature set point' is to be regarded in relation to the charging temperature if
a storage tank thermostat is used.
Time-controlled switchover of storage tank sensors
By configuring a second storage tank sensor SF2, it is possible to determine by setting thefunction block CO4 -> F19 - 1 that the storage tank sensor SF1 is used for day mode in the
DHW circuit and storage tank sensor SF2 for night mode. As a result, different storage tankvolumes can be kept at a constant temperature according to a time schedule and also at different temperatures if the 'DHW temperature set points' for day and night differ from one another.
Stop storage tank charging
The controller stops charging the storage tank when the water temperature measured at storage tank sensor SF1 has reached the temperature T = 'DHW temperature' + 'Hysteresis'.
When there is no heating operation or when the flow temperature demand in the system islower, the corresponding valve is closed. The storage tank charging pump is switched off after t = 'Lag time of storage tank charging pump' x 'Valve transit time'.
With the default settings, the temperature in the storage tank is increased by 5 °C to reach
65 °C when the storage tank temperature falls below 60 °C. The charging temperature is calculated from the DHW temperature (60 °C) plus the 'Charging temperature boost' (10 °C),
which equals 70 °C. When the storage tank has been charged, the heating valve is closed
and the charging pump continues to run for the time t = P06 x Valve transit time. Outside thetimes-of-use, the storage tank is only charged when the temperature falls below 40 °C('Night set point for DHW temperature'). In this case, the tank is charged with a charging
temperature of 50 °C until 45 °C is reached in the tank.

Fig. 16-6: Schematics of a storage tank charging system

The controller begins charging the storage tank when the water temperature measured atstorage tank sensor SF1 falls below the 'DHW temperature set point' by 0.1 °C. If the flow
temperature in the system exceeds the desired charging temperature, the controller tries to reduce the flow temperature in the heating circuit for up to three minutes before the exchanger
charging pump is activated together with the storage tank charging pump. When there is no
heating operation or when the flow temperature in the system is lower, the exchanger
charging pump is switched on immediately. If the temperature currently measured at storagetank sensor SF1 is reached at the flow sensor VF, the storage tank charging pump is switchedon. An activated setting CO4 -> F27 - 1 (discharging protection) causes the charging to be
stopped when the charging temperature does not reach its set point even though the valve isfully open or it falls below the temperature measured at SF1 and does not rise again.
Charging with the valve fully open is stopped after one hour at the latest. In such cases, 'Operation: discharging protection' is displayed with the measured values in the DHW circuit for
the next 30 minutes. If a storage tank thermostat is used, the storage tank charging pump is
switched on when the temperature T = Charging temperature – 5 °C is reached at the flow
sensor VF.
Note
The 'DHW temperature set point' is to be regarded in relation to the charging temperature if
a storage tank thermostat is used.

EB 5573-1 EN

16-63

Appendix A (configuration instructions)

When the flow sensor VF4 is activated, the set point in the heat exchanger circuit is influenced by the system deviation in the storage tank charging circuit upon activation of the storage tank charging pump: if the temperature measured at flow sensor VF4 is lower than thedesired 'Charging temperature', the set point in the heat exchanger circuit is increased insteps of 1 °C. When the set point in the heat exchanger charging circuit reaches the 'Max.
charging temperature', the set point is no longer increased. An “Err 4“ error message is generated.
Note
The set point in the heat exchanger circuit which is valid at the end of the charging cycle will
be used again at the beginning of the next cycle.
If times-of-use have been programmed for DHW heating, the 'DHW temperature set point'
adjusted at the rotary switch is applied during these times-of-use. Outside the times-of-use,
the night set point for DHW temperature is used. This does not apply when a storage tankthermostat is used.
Time-controlled switchover of storage tank sensors
By configuring a second storage tank sensor SF2, it is possible to determine by setting thefunction block CO4 -> F19 - 1 that the storage tank sensor SF1 is used for day mode in the
DHW circuit and storage tank sensor SF2 for night mode. As a result, different storage tankvolumes can be kept at a constant temperature according to a time schedule and also at different temperatures if the 'DHW temperature set points' for day and night differ from one another.
Stop storage tank charging
The controller stops charging the storage tank when the water temperature measured at storage tank sensor SF2 has reached the temperature T = 'DHW temperature' + 'Hysteresis'. To
do so, the heat exchanger charging pump is immediately switched off. When there is no
heating operation or when the flow temperature demand in the system is lower, the corresponding valve is closed. The storage tank charging pump is switched off after the time has
elapsed t = P06 x valve transit time.

16.3.2.1 Cold charging protection
In system Anl 1.1(-1), the cold charging protection function causes a storage tank charging
to be started first when the primary flow temperature is sufficiently high enough.
The CO4 -> F22 - 1 setting automatically activates the FG2 input to measure the primary
flow temperature. If the measured primary flow temperature is lower than the measured storage tank temperature (e.g. due to a supply line that has cooled down at the start of a storagetank charging), the heating circuit valve is moved to the adjusted position at first. The storagetank charging is not released in absolute priority operation until the primary flow temperature has risen enough as a result. Parallel operation must be additionally configured if it is required.

Domestic hot water heating with solar system

The systems Anl 1.3 and 2.3 are fitted with a solar system for DHW heating. In these systems, the difference between the temperatures measured at storage tank sensor SF2 and theflow sensor VF3 at the solar collector is determined. The 'Solar circuit pump ON' parameter
determines the minimum temperature difference between sensors VF3 and SF2 required toactivate the solar circuit pump. If the temperature difference falls below the value of 'Solar
circuit pump OFF', the solar circuit pump is switched off. Basically, the solar circuit pump is
also switched off when either the water temperature measured at sensor SF2 has reached the'Max. storage tank temperature' or when the solar collector temperature rises above 120 °C.
Note
The times-of-use of the DHW circuit do not affect the operation of the solar system.

Priority circuit

In many district heating systems with primary DHW heating, the allotted amount of watercannot meet DHW heating and heating operation demands when they are required at thesame time. As a result, the capacity required for DHW heating needs to be taken from theheating system when great heating loads occur; and this, until DHW demand has been concluded. Nevertheless, heating operation is not to be interrupted simply. Only the amount ofenergy required for DHW heating is to be deducted. This can be achieved by using the priority functions: reverse control and set-back operation.

16.3.8.1 Reverse control
In all systems with DHW heating and at least one heating circuit with a control valve, DHW
heating can be given priority by applying reverse control. With the setting CO4 -> F08 - 1,
the temperature is monitored at sensor VFx.
In systems without sensor VFx in the DHW circuit (e.g. systems Anl 4.5, 11.0), the temperature is monitored directly at storage tank sensor SF1. If system deviations still occur after thetime set in 'Start' has elapsed, the set point of the heating circuit with the control valve isgradually reduced each minute until the flow temperature set point has reached 5 °C at theminimum. How strongly the controller responds is determined by the 'KP' (influence factor).
When 'Start' is set to 0, the priority operation is started regardless of the time and temperature in the system. The control valve of the corresponding heating circuit is closed.
The reverse control can be activated for each heating circuit separately in system Anl 4.5.

16.3.9Forced charging of DHW storage tank

To provide the full network performance for room heating when the time-of-use of the heating circuits begins, any storage tanks are charged one hour before the time-of-use of theheating circuits starts. For the individual controller, this means that storage tank charging is
activated when the water temperature in the storage tank falls below the adjusted deactivation value of T = 'DHW temperature' + 'Hysteresis'.
The forced charging of the storage tank does not take place when the DHW circuit is not
used at the beginning of the time-of-use set for the heating circuit(s).
NoteThis function is not available when a storage tank thermostat is used.

Appendix A (configuration instructions)16.3.10 Thermal disinfection of DHW storage tank
In all systems with DHW heating, a thermal disinfection is performed on a selected day of
the week or daily.
− In systems with DHW storage tank, it is heated up, taking into account the Charging temperature boost parameter (or Set point boost, depending on the system) to the adjusted
Disinfection temperature. Disinfection takes place within the adjusted time period ('Time').
− In systems with storage tank charging system, the CO4 -> F24 -1 setting can be used toactivate the sensor RüF2 instead of SF1 or SF2 to switch off the thermal disinfection.
− In systems with DHW heating in instantaneous heating system, the function remains active taking into account the Boost parameter until the circulation pipe, measured at storage tank sensor SF1, has reached the adjusted Disinfection temperature, provided disinfection has not been terminated prematurely at the end of the adjusted time period(Time).
The 'Duration' determines how long the disinfection temperature must be maintained within
the adjusted time period to rate the process successful. If the Duration is set to a value otherthan 0, no intermediate heating operation takes place during thermal disinfection.
When the 'Disinfection temperature' has not been reached before the end of the thermal disinfection cycle, it is indicated correspondingly on the display. This error message can also be
generated prematurely if the remaining time until the disinfection temperature is reached isshorter than the adjusted 'Duration'. The indication is automatically reset when the disinfection temperature is properly reached during the following thermal disinfection cycle.
Thermal disinfection for preventing legionella infection causes:− Excessively high return flow temperatures during the disinfection cycle (return flow temperature limitation suspended)− Excessively high DHW temperatures after thermal disinfection has been concluded− Possibly lime scale, which can have a negative effect on heat exchanger performance.
Note− This function is not available when a storage tank thermostat is used.
− The forced operation of the circulation pump (DHW) starts while thermal disinfection is active.

Appendix A (configuration instructions)16.4.4Return flow temperature limitation

The temperature difference between the flow and return flow in a network indicates how wellthe energy is used: the greater the difference, the higher the efficiency. A return flow sensor
RÜF is sufficient to evaluate the temperature difference when the flow temperatures are predefined. The return flow temperature can be limited either to a value depending on the outdoor temperature (variable) or to a fixed set point. When the temperature measured at return
flow sensor RüF exceeds the return flow temperature limit, the set point of the flow temperature (flow temperature of the heating system, charging temperature) is reduced. This causes
the primary flow rate to be reduced and the return flow temperature to drop. In systems
Anl 2.x and 4.1, the 'Max. return flow temperature' parameter (PA4 level) is used for limitation in the primary circuit during DHW heating if it is greater than the parameter valid forthe primary circuit. The KP (limiting factor) determines how strongly the controller responds
when the limits are exceeded in either direction (PI algorithm).
If just the proportional component is to be implemented, set CO5 -> F16 - 1. This allows theintegral-action component in the return flow temperature limitation algorithm of all control
circuits of the controller to be deactivated. The set point reading (flow temperature of theheating, charging temperature) blinks to indicate that a return flow limitation is active in thecontrol circuit concerned.
Note
When outdoor-temperature-compensated control with gradient characteristic is used, the return flow temperature is limited to a fixed value by equating the 'Base point for return flow
temperature' and 'Max. return flow temperature' (PA1, 2 - > P13 and P14) parameters.

Three-step control

The flow temperature can be controlled using a PI algorithm. The valve reacts to pulses thatthe controller sends when a system deviation occurs. The length of the first pulse, in particular, depends on the extent of the system deviation and the selected 'KP (gain)' (the pulse
length increases as KP increases). The pulse and pause lengths change continuously until thesystem deviation has been eliminated. The pause length between the single pulses is greatly
influenced by the 'Tn (reset time)' (the pause length increases as TN increases). The 'TY (valve
transit time)' specifies the time required by the valve to travel through the range of 0 to
100 %.

On/off control

The flow temperature can be controlled, for example by activating and deactivating a boiler.
The controller switches on the boiler when the flow temperature falls below the set point by T
= 0.5 x 'Hysteresis'. When the set point is exceeded by T = 0.5 x 'Hysteresis', the boiler isswitched off again. The greater the value you choose for 'Hysteresis', the less frequent switching on and off will be. By setting the 'Minimum ON time', an activated boiler remains
switched on during this period regardless of the flow temperature fluctuations. Similarly, adeactivated boiler will remain switched off regardless of the flow temperature fluctuations if
the 'Min. OFF time' has been specified.

Appendix A (configuration instructions)16.4.8Continuous control

The flow temperature can be controlled using a PID algorithm. The valve receives an analog
0 to 10 V signal from the controller. When a system deviation occurs, 'KP (gain)' immediately causes the 0 to 10 V signal to change (the greater the KP, the greater the change). The integral component becomes effective with time: 'Tn (reset time)' represents the time which
elapses until the integral component has changed the output signal to the same extent as theimmediate change performed by the proportional component (the greater Tn is, the slower
the rate of change will be). Due to the derivative component, any change of the system deviation is incorporated into the output signal with a certain gain (the greater TV is, the stronger
the change will be).

The release of an individual control circuit or the controller with the binary input only becomes effective when the respective control circuit is in automatic mode ( icon). The released control circuit always works in automatic mode; the deactivated control circuit behaves as if it were transferred to stand-by mode. It remains active, however, in any case forprocessing an external demand. The control circuit can be released by the binary input when
the binary input is either a make contact ('Active when BI' = OFF) or a break contact ('Active
when BI' = ON).
Note
− In systems with downstream heating circuit without a valve (Anl 2.x, 4.x), BI1 only influences the operation of this heating circuit.
− In system Anl 3.0, BI1 influences the operation of the entire controller (except for processing an external demand).
− In buffer tank systems Anl 16.x, BI1 influences only the operation of the buffer tankcharging circuit when 'Release control circuit' is configured.

16.4.10 Speed control of the charging pumpThis function allows the delivery rate of the charging pump in systems with buffer tank
(CO1 -> F21 - 1) and in systems with DHW storage tank (CO4 -> F21 - 1) to be varied
based on the temperature. When this function is activated, the input SF2 is automatically activated. In combination with CO1 -> F06 - 0 or CO4 -> F02 - 0, this input is only used forspeed control and not to stop the storage tank charging.
All storage tank charging actions start with the minimum delivery rate of the charging
pumps. As soon as the charging temperature is nearly reached, the delivery rate of thecharging pump is increased and the valve controls the flow rate. If the charging temperaturedrops 5 °C below its associated set point, the delivery rate is reduced again. At the latest
when the temperature at SF2 has reached the 'Start' value to reduce the delivery rate, the linear reduction of the delivery rate based on the temperature at SF2 starts. If the temperature
at SF2 reaches the 'Stop' value to reduce the delivery rate, the charging pump runs again at
the minimum delivery rate. Following the lag time, the charging pump is finally deactivatedwhen the storage is fully charged.

Appendix A (configuration instructions)16.4.11 External demand processing
The controller can process binary or analog requests for an externally required signal by amore complex secondary system. A binary request can only be processed when the input
SF2/RF2 is not assigned to a sensor.
Note
Overheating may occur in the heating circuits of the primary controller without control valve.
Excessive charging temperatures in DHW circuits without control valve controlled by the primary controller are excluded when the default settings of the controller are used: while storage tank charging is active, no flow temperature higher than the charging temperature isused by the primary controller. If the Priority for external demand function is activated, theexternal demand is also processed during storage tank charging. The heating circuits can be
configured in such a way that they only process external demand. The possible settings forheating do not apply with this configuration as only the external demand is processed withassociated UP as feeder pump.

Appendix A (configuration instructions)16.4.13 Capacity limitation in Rk1
The capacity can be limited based on a pulse signal up to 800 pulse/h at BI2. Three different
operating situations exist:− A system with simultaneous room and DHW heating requires maximum energy.
− A system with a fully charged storage tank that is only used for room heating requires
less energy.
− A system that suspends room heating during DHW heating requires less energy.
As a result, three different maximum limit values can be adjusted:− Max. limit value to determine the absolute upper limit− 'Max. limit (heating)' to operate room heating only
− Max. limit (DHW) to operate DHW heating only
In all systems without DHW heating or without heating circuit, only the Max. limit value forthe capacity can be specified. If the 'Max. limit' or 'Max. limit (heating)' parameter is set to'OT', a four-point characteristic configured in CO1 -> F11 - 1 allows the input of four capacity limits for outdoor-temperature-compensated capacity limitation in addition to the outdoor,
flow and return flow temperature values.
All limits are adjusted as pulses per hour (pulses/h). As the reading for the current pulse rate
P (pulse/h) is calculated based on the time interval between incoming pulses, the controller
naturally cannot react immediately to every sudden capacity change in the system.
The flow set point of the control circuit Rk1 is reduced when the pulse rate reaches the currently valid maximum limit. The Limiting factor determines how strongly the controller responds.
Example to determine the limit:
If a capacity of 30 kW is to be limited, the following limit must be set in a heat meter, whichissues one pulse per kilowatt hour:
P=

30 kW
1 kWh/pulse= 30 pulses/h

Note
If the controller indicates CO5 -> F00 - 1, any access to the return flow, flow rate and capacity settings is locked.

16.4.14 Creep feed rate limitation with a binary input
It is possible to report to the controller when the creep feed rate has fallen below a certain
level by using a limit switch of the primary valve connected to the terminals 04/12 or to input RüF1. Either the open ('Active when BI =' OFF) or closed binary input ('Active when BI ='ON) can be configured at terminals 04/12 to indicate that the creep feed rate has fallen below a certain level. Only the closed binary input at RüF1 can be processed. Shortly after thealert, the controller closes the valve Rk1. As soon as the flow temperature falls below the set
point by more than 5 °C after the valve has been closed, control operation is started again.

greater than 10 °C lasts longer than 30 minutes, a voltage signal corresponding to the actual
demand is issued. At the same time, the Rk1 valve is forced to close. After 30 minutes, theexternal demand for heat is canceled (0 V issued) and the control signal output in Rk1 is enabled again.

the data cable is connected to the control station using an RS-485 to RS-232 converter(e.g. CoRe02).
The maximum range of the bus connection (cable length) is 1200 meters. For greater distances, repeaters (e.g. CoRe02) must be used to regenerate the signal level. A maximum of 246

Appendix A (configuration instructions)16.5.2.1 Activating the meter bus
To successfully transfer data from the heat meter, the heat meter must use a standardized protocol in accordance with EN 13757. It is not possible to make a general statement about
which specific data can be accessed in each meter. Contact SAMSON to find out exact details concerning certain meter models. All necessary function block parameters to set up thecommunication with heat meters are available in CO6 -> F10. The meter bus address, modeland reading mode must be specified for the heat meters HM1 to HM3. A meter bus address
must be unique and correspond with the address set in the heat meter. If the preset meter bus
address is unknown, a single heat meter connected to the controller can be assigned the meter bus address 254. The address 255 deactivates the communication with the respective
heat meter. The model to be set for the heat meter can be found in TV-SK 4000179038. In
general, the default setting of 1434 can be used for most devices. The meters can be read either automatically every 24 hours (approx.), continuously or when the coils (= Modbus data
points) assigned to the heat meters are overwritten with the value 1 over the system bus interface.
The additional "meter" page is displayed with connection

16.5.2.2 Flow rate and/or capacity limitation with meter bus
The refreshing rate of the measured variable (flow rate and/or capacity) must be less thanfives seconds to ensure that the limitation can be performed properly. Note that some makes,
particularly battery-operated heat meters, respond with communication pauses when they
are read too frequently. Others might run out of energy early.
− A system with simultaneous room and DHW heating requires maximum energy.
− A system with a fully charged storage tank that is only used for room heating requires
less energy.
− A system that suspends room heating during DHW heating requires less energy.
As a result, three different maximum limit values for Rk1 can be adjusted in all systems with
only one control valve and DHW heating on the secondary side:− Max. limit value to determine the absolute upper limit− Max. limit value for heating to operate room heating only
− Max. limit value for DHW to operate DHW heating only
If the 'Max. limit value for heating' parameter is set to 'OT', a four-point characteristic configured in CO1 -> F11 - 1 allows the input of four flow rate or capacity limits in addition tothe outdoor, flow and return flow temperature values.
In all systems with two control valves, separate maximum limits can be adjusted for the flowrate or capacity.

Memory module/mini module

The use of a memory module (order no. 1400-9379) or mini module (order no. 1400-7436)
is particularly useful to transfer all data from one TROVIS 5573-1 Controller to several other
TROVIS 5573-1 Controllers.
Note
In contrast to the memory module, the mini module is not suitable for transferring the programmed vacations to the individual control circuits or a data logging configuration programmed in TROVIS-VIEW.

EB 5573-1 EN

16-89

Appendix A (configuration instructions)

The memory module/mini module is plugged into the RJ45 connector socket located at the side of the controller.
Once the module has been connected, 'Save settings' appears on the controller display. If the memory module already contains data from a different TROVIS 5573-1 Controller, turn the rotary pushbutton until 'Load settings' isdisplayed.
− Pressing the rotary pushbutton to confirm 'Save settings' causes the controller settings to be transferred tothe memory module/mini module.
− Pressing the rotary pushbutton to confirm 'Load settings' causes the controller settings to be transferredfrom the memory module/mini module.
During data transfer, the zeros and ones run across thedisplay. When the transfer was successful, 'OK' is displayed. After that, the connection between controller andmemory module/mini module can be terminated.

Using TROVIS-VIEW (order no. 6661-1014), it is possible to configure all controller settings
on a convenient user interface at the computer and to document these settings.

The data logging module is plugged into the RJ-45 connector socket located at the side of the controller. Once themodule has been connected, 'Start data logging' and 'Copy logging data' appear on the controller display.
− Pressing the rotary pushbutton to confirm 'Start data
logging' causes the above listed operating values to be
saved cyclically to the inserted data logging module.
The controller display returns to the reading indicatedwhen the data logging module was connected.
− Pressing the rotary pushbutton to confirm 'Copy logging data' causes already logged data to be transferred from the memory controller to the data logging
module. During data transfer, the zeros and ones run
across the display. When the transfer was successful,'OK' is displayed. After that, the connection between
controller and data logging module can be terminated.

Note− The controller starts to write over the oldest data as soon the memory of the data logging
module is full after approximately eight days. The current memory capacity of the data logging module can be read in the extended operating level under 'Logging memory' as thesecond value in the sequence (range of values: 0 to 6035). Directly after inserting the data
logging module, data can be first read after the first scanning cycle has been performed.
− The internal memory of the controller is full after approx. 14 days. After that, the controller
