3.4 Calibrating sensors
The controller is designed for connection of Pt 1000, PTC and Ni 1000 sensors.
−− CO5 > F01 - 1, F02 - 0: Pt 1000
−− CO5 > F01 - 0, F02 - 0: PTC
−− CO5 > F01 - 1, F02 - 1: Ni 1000
The resistance values are listed on page 151.
If the temperature values displayed at the controller differ from the actual temperatures, the
measured values of all connected sensors can be recalibrated. To calibrate a sensor, the currently displayed sensor value must be changed such that it matches the temperature (reference temperature) measured directly at the point of measurement. Sensor calibration is activated in CO5 in F20 function block.
An incorrect sensor calibration can be deleted by setting F20 - 0.

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:

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.

Functions of the heating circuit
6.3 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 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.
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 interrupting the power supply. Any power failure that occurs while the function is running automati-

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 tank systems 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).
With CO1 > F21 - 1, 10Vout 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 10Vout is reduced within the range between the limits entered in 'Start speed
reduction' and 'Stop speed reduction'. 10Vout is set to 0 V 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'.

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

time, the calculated outdoor temperature is adapted to the actual outdoor temperature in

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

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.
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

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 > 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.

flow temperature set point is corrected by 1 °C. 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. 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.

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 > 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 > P01 ('Flow gradient').

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 and/or PA2 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 fourpoint characteristic function have no effect.

Fig. 6: Schematics of a storage tank system
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 storage
tank 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 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

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

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


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


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.

Stop storage tank charging
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 =

7.4 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 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.

Note:

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.

7.9 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.
7.9.1 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), 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 re96

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.

7.10Forced 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).

Note:
This function is not available when a storage tank thermostat is used.
7.11Thermal 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.
If the time period ('Time') is set to OFF, disinfection is controlled depending on the switching

Frost protection measures are taken when the outdoor temperature falls below 'Limit'. The

Restricted frost protection: frost protection measures are taken only when all heating circuits
in the system are in stand-by mode. The circulation pumps are automatically switched on and
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.
Frost protection with highest priority: the heating circuit circulation pumps are always
switched on automatically. The flow temperature set points of all heating circuits currently in
stand-by mode are set to +10 °C. In the DHW circuit, the circulation pump is always activated. If the storage tank temperature falls below +5 °C, the storage tank is recharged to
+10 °C.

Frost protection operation of a pump, a heating circuit or the DHW circuit is only active when the frost protection icon is displayed. In the stand-by mode ( ) fixed set
point control without outdoor temperature sensor does not include frost protection.
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 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 for the 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 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.

8.5 Condensate accumulation control
Activate the damping function to start up condensate accumulation plants, in particular to
avoid problematic excess temperatures. The controller response to set point deviations which
cause the primary valve to open is attenuated. The controller response to set point deviations
which cause the control valve to close remains unaffected.

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
BA_EQJW146F002_EN001

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).

NOTICE
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 is

As described in the error list, sensor failures are indicated by displaying “Err 1" 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 > 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: 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 no
longer charged (exception: solar system).

When Modbus is activated and, at the same time, the dial-up in case of error is released, the
connection with the building control station is established first and then the text message is
sent. If the first attempt to connect to the building control station fails, the controller tries
again until the programmed number of redialing attempts has been exhausted.

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 station 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 "Err 7" error message (Unauthorized access occurred). 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.
NOTICE
Upon installation, observe the relevant standards and regulations governing lightning
and overvoltage protection.

10.3Description of communication parameter settings
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
string is to be marked by '–'. The phone number may include a maximum of 22 characters.
Example: 069, 2 sec. pause, 4009, 1 sec. pause, 0:
0 6 9 P P 4 0 0 9 P 0 – (= 11 characters)

Note:
The connected modem is automatically configured when the function block CO6 >
F04 - 1 is activated.
10.4Meter bus
TROVIS 5573-100x version
The controller can be connected to an optional meter bus/Modbus gateway (1400-9867)
(RJ-45 connector socket). The gateway can communicate with up to six M-Bus units according to EN 1434-3. Flow rate and/or capacity limitations in RK1 or RK2 control circuit is possible on the basis of the values measured at heat meter WMZ1 and WMZ2.
TROVIS 5573-110x version
The controller has an interface for three M-bus units according to EN 1434-3. Flow rate
and/or capacity limitations in RK1 or RK2 control circuit is possible on the basis of the values
measured at heat meter WMZ1 and WMZ2.

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 WMZ6
(TROVIS 5573-100x) or WMZ1 to WMZ3 (TROVIS 5573-110x). A meter bus address must
118
BA_EQJW146F002_EN001
Communication
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 WMZ6 are overwritten with the value 1 over the system bus interface. In extended operating level (see note on page 10), 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
CO6 > F10.

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:
BA_EQJW146F002_EN001
119
Communication
−− 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 0.00 or 0.0, a four-point characteristic configured in CO1 > F11 - 1 allows the input of four flow rate or capacity limits 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 control valves, separate
maximum limits can be adjusted for the flow rate and capacity.

Note:
Since only the 'Max. limit value for heating' can be set to 0.00 or 0.0, a system with
DHW heating must be configured even if a DHW heating is not used to allow the parameterization of a outdoor-temperature-compensated flow rate or capacity limitation. For example, system Anl 2.0 with a deselected storage tank sensor would need
to be configured in place of system Anl 1.0.
Flow limitation
All settings required to set up flow rate limitation are available in CO6 > F11 or CO6 > F13
for systems with two control valves. One after the other, the system's max. limit value and –
for systems with only one control valve and DHW heating on the secondary side – the max.
limit value for heating and the max. limit value for DHW have to be set. The 'Limiting factor'
determines how strongly the controller responds when the limit values are exceeded in either
direction.
NOTICE
If the controller indicates CO5 > F00 - 1, any access to the return flow, flow rate and
capacity settings is locked.

10.5Memory module
The use of a memory module (order no. 1400-9379) is particularly useful to transfer all data
from one TROVIS 5573 Controller to several other TROVIS 5573 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 5573 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.
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
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.
BA_EQJW146F002_EN001
123
Communication

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.
−−The terminals 20, 22, 25 and 28 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 18 to terminals 20, 22, 25 and 28.Do not
connect ELV wiring (according to VDE 0100) to these terminals.
−−Before performing any work on the controller, disconnect it from the power supply.
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.
−− 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.

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.
Connecting actuators
−− 0 to 10 V control output: Use cables with a minimum cross-section of 2 x 0.5 mm².
−− Three-step or on/off outputs: Connect cables with at least 1.5 mm² suitable for damp locations to the terminals of the controller output. The direction of travel needs to be
checked at start-up.
