Functions of the heating circuit
6 Functions of the heating circuit
Which controller functions are available depends on the selected system code number (Anl).
6.1 Outdoor-temperature-controlled 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 the
flow temperature set point as a function of the outdoor temperature (see Fig. 3). 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.

6.1.1 Gradient characteristic
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:
The gradient needs to be increased if the room
temperature drops when it is cold outside.

Functions of the heating circuit
Outside the times-of-use, reduced set points are used for control: the reduced flow set point is
calculated 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
Note:
Particularly 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 the heating characteristic has been adapted to the building/heating surface
layout.

6.3 Underfloor heating/drying of jointless floors
Using function block setting CO1, 2, 3 > 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, 3 parameter levels:
−− Value range of the gradient: 0.2 to 1.0
−− Value range of the maximum flow temperature: 5 to 50 °C
In addition, it is possible to activate the drying of jointless floors function. In connection with
this, the function block parameters are listed which appear after activating this function
block. They determine the drying process: the first heating up phase starts at the entered Start
temperature, which has a flow temperature of 25 °C in its default setting. In the course of 24
hours, this temperature is raised by the value entered in 'Temp. rise/day', i.e. the default setting causes the flow temperature set point to rise to 30 °C. If the maximum temperature is
reached, it is kept constant for the number of days entered in 'Duration'. 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 block parameter '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 starts with a flow temperature of 25 °C, which is kept constant for three
days. Afterwards, 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 'Hold' and 'Reduction' can be be selected to
continue an interrupted drying process. The course of the drying process can be monitored in
the operating level by reading the measured data of the associated heating circuit.
'Done' is displayed after the last phase is completed. This disappears from the display after
resetting the display to Stop in CO1, 2 > F05 or after interrupting the power supply. Any
power failure that occurs while the function is running automatically restarts the drying func112 EB 5578 EN

tion. In systems in which the drying function is 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.

6.4 Outdoor temperature for rated operation (day)
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'. Reduced operation restarts after the outdoor temperature rises above the limit (plus
0.5 °C hysteresis).
This function is activated at very low temperatures to avoid that the building cools down excessively outside the times-of-use when low outdoor temperatures occur.

6.5 Buffer tanks stems Anl 16.x
The systems Anl 16.x are fitted with a butter tank. The buffer tank can be charged by the district heating system according to an adjustable characteristic or to an adjustable fixed set
point. The storage tank charging pump SLP is controlled to the storage tank set point (e.g.
45.3 °C), which is based on the outdoor temperature. Storage tank charging starts when
temperature falls below the outdoor-temperature-based set point at SF1. The charging temperature results from the outdoor-temperature-based set point plus 6 °C (e.g. 51.3 °C). The
storage tank charging is finished when the temperature at SF2 exceeds the outdoor-temperature-based set point by 3 °C (e.g. 48.3 °C).
EB 5578 EN
113
Functions of the heating circuit
With CO1 > F21 - 1, the 0 to 10 V output for speed control of the storage tank charging
pump is available. All storage tank charging actions start with the minimum pump speed
(function block parameter: 'Min. speed signal'). As soon as the charging temperature at VF1
is nearly reached, the speed of the storage tank charging pump is increased and the valve
controls the flow rate. If the temperature at SF2 reaches the value entered in 'Start speed reduction', the signal level at the 0 to 10 V output is reduced within the range between the limits entered in 'Start speed reduction' and 'Stop speed reduction'. 0 V is issued when the storage tank charging pump is switched off.
For systems without a downstream control circuit, a transmitted external demand causes the
feeder pump UP1 to be activated and can override the current buffer tank set point, if necessary. For systems with a downstream control circuit, either a transmitted external demand or
the demand of the downstream control circuit causes the feeder pump UP1 to be activated,
regardless of the CO5 > F14 setting. Regardless of the CO5 > F14 setting, the external demand and the demand of the downstream control circuit can override the current buffer tank
set point.
The pump UP2 of the solid fuel boiler circuit starts to run when the temperature reaches 'Start
temperature for boiler pump' at VF2. The boiler pumps 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 sensor SF2 for
control. The collector circuit pump CP is activated when the temperature at the collector 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 the valve entered in
'Solar circuit pump OFF' or when the temperature at the storage tank sensor SF2 reaches
'Max. storage tank temperature'.

Note:
The buffer tank control circuit is deactivated as described in section 6.4. 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.

6.6 Summer mode
Summer mode is activated depending on the mean daytime temperature (measured between
7.00 h and 22.00 h) during the adjusted summer time period. 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
the mean daytime temperature falls below the 'Limit' on the number of successive days set in
'No. days until deactivation', summer mode is deactivated on the following day.

6.7 Delayed outdoor temperature adaptation
The calculated outdoor temperature is used to determine the flow temperature set point. The
heat response is delayed when the outdoor temperature either increases or decreases or
both. If the outdoor temperature varies by, for example 12 °C within a very short period of
time, the calculated outdoor temperature is adapted to the actual outdoor temperature in

Note:
The delayed outdoor temperature adaptation helps avoid unnecessary overloads of
central heating stations in combination with either overheated buildings occurring, for
example due to warm winds or temporarily insufficient heating due to the outdoor
sensor being exposed to direct sunshine. In the operating level, the outdoor temperature blinks on the display while delayed outdoor temperature adaptation is active. A
small hour glass appears next to the thermometer on the display when this function is
active. The calculated outdoor temperature is displayed.

6.9 Optimization
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 the
reference 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, the
or icon blink on the display.

Functions of the heating circuit
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
times-of-use, this can prematurely cause the controller to heat up to the 'Day set
point'.

6.10Flash adaptation
To ensure that the controller reacts immediately to room temperature deviations during rated
or reduced operation, the function block setting CO1, 2, 3 > 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' and 'KP
(gain)' are set to a value other than 0. The 'Cycle time' determines the intervals at which the
flow temperature set point is corrected by 1 °C. A 'KP (gain)' set to a value other than 0
causes a direct increase/decrease in flow temperature set point when a sudden deviation in
room temperature arises. A 'KP (gain)' setting of 10.0 is recommended.

Note:
−−Cooling loads, such as drafts or open windows, affect the control process.
−−Rooms may be temporarily overheated after the cooling load has been eliminated.

6.11Adaptation
The controller is capable of automatically adapting the heating characteristic to the building
characteristics. provided a gradient characteristic has been set (CO1, 2, 3 > F11 - 0). The
reference room, where the room sensor is located, represents the entire building and is monitored to ensure that the room set point ('Day set point') is maintained. When the mean measured room temperature in rated operation deviates from the adjusted set point, the heating
characteristic is modified accordingly for the following time-of-use. The corrected value is displayed in PA1, 2, 3 > P01 (Gradient, flow).

6.12Cooling control
Cooling control with outdoor sensor
When the cooling control function is activated in a control circuit with outdoor sensor, the
four-point characteristic of the corresponding control circuit is automatically activated and
the operating direction of the control output is reversed. In PA1, PA2 and/or PA3 the four
points for the course of the set point based on the outdoor temperatures can be adjusted separately for day and night mode. The 'Base point for return flow temperature' that can be adjusted with an active return flow sensor determines the point at which a minimum limitation
of the return flow temperature starts: if the measured return flow temperature falls below this
value, the flow temperature set point is raised. The four return flow temperature values in the
four-point characteristic function have no effect.

Note:
−−The limiting factors KP of the Return flow sensor (CO1, 2, 3 -> F03) functions apply during cooling control as well.
−−The request for a signal by downstream control circuits or externally (when a
pre-control circuit is used) is based on the maximum selection. Therefore, systems
(e.g. system Anl 5.0) or controllers connected over a device bus are not suitable for
transmitting the signal for required cooling. The 'Set point boost (pre-control circuit)'
parameter can only generate higher and not lower set points in the pre-control circuit.

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 1. This
function enables storage tank charging when the heating system is switched off, e.g. in summer 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.

Functions of the DHW circuit
Time-controlled switchover of storage tank sensors
By configuring a second storage tank sensor 2, it is possible to determine by setting the function block CO4 > F19 - 1 that the storage tank sensor 1 is used for day mode in the DHW
circuit and storage tank sensor 2 for night mode. As a result, different storage tank volumes
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 1 has reached the temperature T = 'DHW temperature' + 'Hysteresis'. 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 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
60 °C when the storage tank temperature falls below 55 °C. The charging temperature is calculated from the DHW temperature (55 °C) plus the 'Charging temperature boost' (10 °C),
which equals 65 °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 the
times-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.

The controller begins charging the storage tank when the water temperature measured at
storage tank sensor 1 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 storage
tank sensor 1 is reached at the flow sensor VF or after three minutes at the latest, the storage
tank charging pump is switched on. 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.
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 the
desired 'Charging temperature', the set point in the heat exchanger circuit is increased in
steps of 1 °C. When the set point in the heat exchanger charging circuit reaches the 'Max.
126 EB 5578 EN
Functions of the DHW circuit
charging temperature', the set point is no longer increased. An error message (Max.
charging temp.) 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 tank
thermostat is used.

The controller stops charging the storage tank when the water temperature measured at storage tank sensor 2 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 =

with a solar system for DHW heating. In these systems, the difference between the temperatures measured at storage sensor SF2 and the sensor at the solar collector VF3 is determined.
The 'Solar circuit pump ON' parameter determines the minimum temperature difference between sensors VF3 and SF2 required to activate 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.

This does not include operating situations during which the current flow temperature demand
of the pump circuit is lower than the adjusted 'Temperature limit'. In this case, the controller
applies priority operation, if necessary with intermediate heating. Once a parallel pump operation cycle has been activated and the time period set in 'Stop' has elapsed, system deviations greater than 5 °C cause the controller to suspend parallel operation for 10 minutes and
to apply priority operation.

7.8 Priority position
In many district heating systems with primary DHW heating, the allotted amount of water
cannot meet DHW heating and heating operation demands when they are required at the
same time. As a result, the capacity required for DHW heating needs to be taken from the
heating 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 of
energy required for DHW heating is to be deducted. This can be achieved by using the priority functions: reverse control and set-back operation.
7.8.1 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. Anl 4.5, 11.0, 12.0, 13.0 and 21.0),
the temperature is monitored directly at storage tank sensor 1. If system deviations still occur
after the time set in Start has elapsed, the set point of the heating circuit with the control valve
is gradually reduced each minute until the flow temperature set point has reached 5 °C at the
minimum. 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 valves of the corresponding heating circuits are closed.

In systems without sensor VFx in the DHW circuit (e.g. Anl 4.5, 11.0, 12.0, 13.0 and 21.0),
the temperature is monitored directly at storage tank sensor 1. If system deviations still occur
after the time set in 'Start' has elapsed, the selected heating circuits with the control valve are
set to reduced operation.
When 'Start' is set to 0, the priority operation is started in all heating circuits regardless of
the time and temperature in the system.

7.9 Forced 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 the
heating 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).

This function is not available when a storage tank thermostat is used.

Functions of the DHW circuit
7.10Thermal 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 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 1, 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 other
than 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 is
shorter 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 return flow temperature limitation in the primary control circuit is deactivated also

their flow temperature set points are adjusted to 10 °C. The circulation pump in the DHW circuit is automatically switched on only when the stand-by mode has been adjusted at the rotary switch in all heating circuits. Nevertheless, the storage tank is always recharged to 10 °C
if the storage tank temperature falls below 5 °C.

8.3 Forced pump operation
When the heating circuit pumps have not been activated for 24 hours, forced operation of
the pumps is started between 12.02 h and 12.03 h. This is done to avoid that the pumps get
stuck when they are not operated for long periods of time. In the DHW circuit, the circulation
pump is operated between 12.04 h and 12.05 h, the other pumps between 12.05 h and
12.06 h.
8.4 Return flow temperature limitation
The temperature difference between the flow and return flow in a network indicates how well
the energy is used: the greater the difference, the higher the efficiency. A return flow sensor
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 return flow temperature measured at return flow sensor exceeds the limit, the flow temperature set point is reduced. When
the temperature measured at return flow sensor RüF exceeds 'KP (limiting factor)', 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, 3.1 to 3.4, 4.1 to 4.4, 5.1, 5.2, 7.x, 8.x and 9.x, 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 for the primary circuit.The KP
EB 5578 EN
135
System-wide functions
(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 the
integral-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 the
heating, charging temperature) blinks to indicate that a return flow limitation is active in the
control 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

8.5 Condensate accumulation control
Activate the damping function to start up condensate accumulation plants, in particular to

8.6 Three-step control
The flow temperature can be controlled using a PI algorithm. The valve reacts to pulses that
the 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 the
system 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 %.

8.7 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 is
switched 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, a
deactivated boiler will remain switched off regardless of the flow temperature fluctuations if
the 'Min. OFF time' has been specified.

8.8 Continuous control in control circuit RK1
The flow temperature in the control circuit RK1 can be controlled using a PID algorithm. The
valve in RK1 control circuit 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 the immediate 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).

8.9 Releasing a control circuit/controller with binary input
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 for
processing 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

8.10Speed control of charging pump
This function controls the speed of the storage tank charging pump in buffer tank systems
(Anl 16.x) and in DHW circuits. An active speed control of the charging pump (CO4 > F21 1) causes the storage tank sensor SF2 to be activated, however, in combination with CO4 >
F02 - 0 only to measure the speed control. In buffer tank systems, CO1 > F21 - 0 only activates the function.
All storage tank charging actions start with the minimum pump speed (function block parameter: 'Min. speed signal'). As soon as the charging temperature is nearly reached, the speed
of the storage tank charging pump is increased and the valve controls the flow rate. If the
temperature at SF2 reaches the value entered in 'Start speed reduction', the signal level at
the 0 to 10 V output is reduced within the range between the limits entered in 'Start speed reduction' and 'Stop speed reduction' (10 V to 'Min. speed signal' corresponds with 'Start

NOTICE
Overheating may occur in the heating circuits of the primary controller without control valve.

8.12Capacity limitation in RK1
The capacity can be limited based on a pulse signal 3 to 800 pulse/h at terminals 17/18.
This only applies to systems which do not use input SF3/FG3. 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 value for heating to operate room heating only
−− Max. limit value for DHW to operate DHW heating only
EB 5578 EN
141
System-wide functions
In all systems without DHW heating or without heating circuit, only the Max. limit value for
the capacity can be specified. If the 'Max. limit' or 'Max. limit for heating' parameter is set to
AT, 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] (–> extended operating level, key number 1999) 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, which
issues one pulse per kilowatt hour:
P=

Activate the device bus and specify the device bus address for each device. Note that the device bus address 1 is to be set for just one controller in the system and that all device bus addresses must be unique. The controller with device bus address 1 implements the required
bus bias voltage for the system. Once the controllers have been connected and set accordingly, additional functions can be configured. These partly application-specific functions include:

System-wide functions
8.14.1 Requesting and processing an external demand
In general, the controller which controls the primary valve or boiler (= primary controller) in
a system of linked controllers will process the demand of all subsequent controllers (= secondary controllers). As a result, the primary controller must be configured to receive this demand. Usually, the secondary controllers are configured such that they send their maximum
flow set point to the primary controller.
In special cases, however, it might happen that only the set point of one control circuit is to
be sent. The appropriate function blocks to do so are also available for selection. After the
selected function blocks have been activated, you must specify a register number. The following applies: in a system of linked controllers which are hydraulically supplied by a primary
controller, all controllers (primary and secondary controllers) must have the same register
number setting for the 'Demand register'.
A controller which is configured to receive a demand in register no. 5 will not process a demand sent to register no. 6. The primary controller compares the received requested demands and its own requested demand and supplies the system with the required flow temperature (if necessary, increased by the 'Set point boost (pre-control circuit)'.

Overheating may occur in the heating circuits of the primary controller without control valve.

return flow temperature limitation in the primary circuit so that it is raised to the value adjusted for the maximum return flow temperature (or for point 1 of the return flow temperature in
a four-point characteristic). Controllers configured to trigger this function must generate the

down, the valve of this circuit is closed while its circulation pump remains activated.
If a secondary heating circuit without valve is to shut down, just its circulation pump and not
the primary circuit (RK1) is shut down, for example in systems Anl 2.x by configuring 'Receive release HC1'.

8.14.6 Display error messages issued by the device bus
The setting CO7 > F16 - 1 causes the controller to react to the error messages from the device bus by generating the 'External err' error message as long as the faults of the other device bus participants exist.
Regardless of the CO7 > F16 setting, error messages received over device bus basically lead
to the control station (GLT) being dialed when the modem function is active. You can define
which error messages are to be passed on over the device bus after entering the key number
0025. The default setting of 465 causes the controller to pass on just the messages highlighted (bold) in the table in section 9.4 over the device bus, except for 'External err'.

As described in the error list, sensor failures are indicated by displaying '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
three dashes 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, 3 > P07) is lower than 50 °C.
−− 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 using 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, the
controller behaves as if VF4 has not been configured. As soon as the control of the
charging temperature becomes impossible (VF2 defective), the associated valve is closed.
−− Return flow sensors RüF1/2/3: When the return flow sensor fails, the controller continues operation without return flow temperature limitation.
−− Room sensors RF1/2/3: 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 no
longer charged (exception: solar system).

9.4 Error status register
The error status register is used to indicate controller or system errors. In modem operation
when the controller dials the building control system (GLT) both when an error is detected
and when it has been corrected (CO6 > F06 - 1), each change in the status of the error status register causes the controller to dial the control system. The error messages which cause a
change in the state of the configured fault alarm output (with CO5 > F07 - 1) are highlighted
in the following table (bold).
The function blocks in the CO8 configuration level allow single controller inputs that are not
used to be added to the error status register as binary inputs. Either an open or closed binary input can be configured to indicate an error. The controller indicates 'Binary alarm' when
at least one of the inputs configured in this way registers an error.

Note:
If free inputs are to issue binary signals to a building control station without affecting
the error status register, activate the corresponding function block in the CO8 configuration level and select '- - -' as the function block parameter.

Using the optional communication module, the TROVIS 5578 Heating Controller can communicate with a control system. In combination with a suitable software for process visualization
and communication, a complete control system can be implemented. The following communication versions are possible:
−− Operation with a dial-up or GSM modem using the RS-232 to modem communication
module: basically, communication is only established automatically when errors occur in
the system. The controller works autonomously. Nevertheless, the modem can dial up to
the controller at any time to read data from it or otherwise influence it, if necessary. The

10.1RS-232 to modem communication module
When looking onto the controller front, the connection for the optional communication module is located on the left side of the controller housing (RJ-45 connector socket). A dial-up or
GSM modem can be connected to the controller over the RS-232 to modem communication
module (8812-2004). A dial-up modem is required if the controller is to be connected to the
telecommunications network. In this case, the controller works autonomously and can initiate
a call to the building control station when errors occur. Additionally, the building control sta-
EB 5578 EN

Communication
tion can dial up to the controller, read data from it and send new data once the valid key
number has been written to holding register no. 40145.

Note:
If a wrong key number has been written to holding register no. 40145 for the third
consecutive time, the controller immediately interrupts the modem connection and
generates an 'Unauthorized access' message. As a result, the call to the configured
control system is triggered and a text message is sent. Bit D6 is deleted as soon as the
error status register has been read by the control system and the connection has been
terminated.
In special cases, the lock dial-up function can be selected to stop dial-up in case an error occurs. Using the dial-up upon corrected error function, the controller additionally informs the
building control station when a previously signaled error no longer persists.
The automatic modem configuration function causes the dial-up modem connected to the
controller to be configured automatically by the controller.

10.2RS-485 communication module
When looking onto the controller front, the connection for the optional communication module is located on the left side of the controller housing (RJ-45 connector socket). A permanent
bus connection (data cable) is required to operate the controller in combination with the RS485 communication module (8812-2002). The bus line links the control units/devices in an
open ring. At the end of the bus line, the data cable is connected to the control station using
an RS-485/RS-232 converter (e.g.  CoRe01, refer to Data Sheet T 5409).
The maximum range of the bus connection (cable length) is 1200 meters. A maximum of
126 devices can be connected to such a segment. For greater distances or when more than
126 devices are to be connected to a line, repeaters (e.g. CoRe01) must be used to regenerate the signal level. A maximum of 246 devices with 8-bit addressing can be connected to a
bus. If no communication is established between the control system and controller, the time of
access by the control system can be restricted to dynamic process by the monitoring function.
The controller resets the monitoring function, provided the valid Modbus requests are registered. However, in case of an error, all level bits are initialized back to “autonomous” after
30 minutes have elapsed.

Upon installation, observe the relevant standards and regulations governing lightning
and overvoltage protection.

Modbus station address (8 bit)
This address is used to identify the controller in bus or modem mode. In a system, each controller needs to be assigned a unique address.
Modem dialing pause (P)
We recommend to keep dialing pause for approx. 3 to 5 minutes between dialing up to the
control system/the text messaging center to avoid a permanent overloading of the telecommunications network. The Modem dialing pause defines the interval between two dialing attempts.
Modem timeout (T)
When the controller connects to the control station (GLT) but without addressing a Modbus
data point, the connection is terminated after the time specified for 'Modem timeout' has
elapsed. If the error status register has not been read during the GLT connection, the controller dials up the GLT again after the Modem dialing pause (P) has elapsed.
When sending a text message, the specified time is without meaning.
Number of redialing attempts (C)
The controller tries to dial up to the control system again, observing the Modem dialing
pause, in case the GLT/text messaging center is busy or the function that triggered the call
has not been reset by the controller. After the specified number of redialing attempts have
failed, OFF is indicated in the controller's extended operating level. The dialing attempt
counter is automatically reset at 12:00 h and the controller tries to connect again.
Resetting of triggered call = Reading the error status register (HR40150)
Phone number of control station
Enter the phone number of the control system modem including the dialing code, if necessary. Short pauses between the numbers can be entered using P (= 1 second); the end of the

10.4Meter bus
The TROVIS 5578 Controller is fitted with an M-Bus interface for max. three M-Bus units. For
systems with three control circuits, a flow rate and/or capacity limitation can be be configured in every control circuit based on the measured data of the heat meters WMZ1 to
WMZ3.

Note:
Details on the use of the different heat or water meters can be found in the technical
documentation TV-SK 6311.
10.4.1 Activating the meter bus
To successfully transfer data from the heat meter, the heat meter must use a standardized protocol in accordance with EN 1434-3. It is not possible to make a general statement about
which specific data can be accessed in each meter. For details on the different meter makes
refer to the technical documentation TV-SK 6311. All necessary function block parameters to
set up the communication with heat meters are available in CO6 > F10. The meter bus address, model code and reading mode must be specified for the heat meters WMZ1 to
WMZ3. A meter bus address must be unique and correspond with the address set in the
WMZ. 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 WMZ.The model code to be set for the heat meter can be found
in TV-SK 6311. 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 WMZ1 to WMZ3 are overwritten
with the value 1 over the system bus interface. In extended operating level (see note on
page 12), the respective measuring and limit values are displayed after confirming the
plant scheme when the flow rate and/or capacity limitation is configured.

Note:
After restarting components (controller or gateway) by connecting them to the power
supply, it may take up to two minutes before the controller allows access to

10.4.2 Flow rate and/or capacity limitation with meter bus
The refreshing rate of the measured variable (flow rate and/or capacity) must be less than
fives seconds to ensure that the limitation can be performed properly. The technical documentation TV-SK 6311 lists the heat meters which comply with this criterion and, therefore
can be used for limitation. 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. For details refer to the above mentioned TV-SK document.
−− 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' or 'Max. limit for heating' parameter for HC1 is set to AT, a four-point
characteristic configured in CO1 > F11 - 1 allows the input of four flow rate or capacity limits for outdoor-temperature-compensated flow rate or capacity limitation in addition to the
outdoor, flow and return flow temperature values.
In all systems without DHW heating or without heating circuit, only the max. limit value for
the flow rate or capacity can be specified. In all systems with two or three control valves, separate maximum limits can be adjusted for the flow rate and capacity.
Flow limitation
All necessary function block parameters to set up the flow rate limitation are available in
CO6 > F11 or CO6 > F13 and CO6 > F15 for the second and third control circuit. One after
the other, the system's max. limit or max. limit for heating and the max. limit for DHW for
systems with only one primary control valve and secondary DHW heating have to be set. The
160 EB 5578 EN

'Limiting factor' determines how strongly the controller responds when the limit values are exceeded in either direction.

10.5Memory module
The use of a memory module (order no. 1400-9379) is particularly useful to transfer all data
from one TROVIS 5578 Controller to several other TROVIS 5578 Controllers.
The memory module is plugged into the RJ-45 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 5578 Controller, turn the rotary pushbutton until 'Load settings' is displayed.
−− Pressing the rotary pushbutton to confirm 'Save settings' causes the controller settings to be transferred to
the memory module.
−− Pressing the rotary pushbutton to confirm 'Load settings' causes the controller settings to be transferred
from the memory module.
162 EB 5578 EN
Communication
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
memory 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.
10.6Data logging
A data logging module (order no. 1400-9378) saves the following controller data every two
minutes:
−− Temperatures measured by the sensors
−− Control signals [%]
−− Switching states of the pump outputs
−− Error status register and its archive
−− Access to the controller settings

Communication
The data logging module is plugged into the RJ-45 connector socket located at the side of the controller. Once the
module 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 controller settings to be transferred
to the data logging module. The controller display returns to the reading indicated when 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.

Installation

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 the second 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 starts to write over the oldest data.
The data log viewer software allows the data to be viewed in graph format. The USB converter 3 (order no. 1400-9377) is required to connect the data logging module to a computer.
The data log viewer software is supplied together with the USB converter 3.

DANGER!
Risk of electric shock!
−−For electrical installation, you are required to observe the relevant electrotechnical
regulations of the country of use as well as the regulations of the local power suppliers. Make sure all electrical connections are installed by trained and experienced
personnel.
−−Before performing any work on the controller, disconnect it from the power supply.
−−The terminals 33, 39, 42 and 45 allow safety equipment which have a direct influence on individual electric acutators and pumps to be integrated. If this is not the
case, connect a jumper from terminal 31 to terminals 33, 39, 42 and 45. Do not
connect ELV wiring (according to VDE 0100) to these terminals.
Notes on electric wiring
−− Install the 230 V power supply lines and the signal lines separately! To increase immunity, keep a minimum distance of 10 cm between the lines. Make sure the minimum distance is also kept when the lines are installed in a cabinet.
168 EB 5578 EN
Electrical connection
−− The lines for digital signals (bus lines) and analog signals (sensor lines, analog outputs)
must also be installed separately!
−− In plants with a high electromagnetic noise level, we recommend using shielded cables
for the analog signal lines. 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 the PE grounding conductor with a 10 mm² cable using the shortest route.
−− Inductances in the control cabinet, e.g. contactor coils, are to be equipped with suitable
interference suppressors (RC elements).
−− Control cabinet elements with high field strength, e.g. transformers or frequency converters, must be shielded with separators providing a good ground connection.
Overvoltage protection
−− If signal lines are installed outside buildings or over large distances, make sure appropriate surge or overvoltage protection measures are taken. Such measures are indispensable for bus lines.
−− The shield of signal lines installed outside buildings must have current conducting capacity and must be grounded on both sides.
−− Surge diverters must be installed at the control cabinet inlet.
Connecting the controller
Wall mounting
To connect the wiring, pull the controller out of its base. To connect the feeding cables, break
through the holes in the marked locations at the top or bottom at the base housing and fit
supplied grommets or suitable cable glands. Ensure that the cables are not subject to torsion
or bending by taking suitable precautions before inserting the cable.
The controller is connected as illustrated in the following wiring diagrams.
Open the housing to connect the cables. To connect the feeding cables, make holes in the
marked locations at the top, bottom or back of the base of the housing and fit suitable grommets or cable glands.
Connecting sensors
Cables with a minimum cross-section of 2 x 0.5 mm² can be connected to the terminals at
the base of the housing.
