Functions of the heating circuit

Functions of the heating circuit
Which controller functions are available depends on the selected system code number (Anl).
5.1 Functioning principle
The heating circuit with the highest flow set point has priority. This principle applies to all heat-
ing circuits with mixing valves. In systems Anl 3, 5 and 8, the pump circuit has priority. The flow
set point of the heating circuit with priority is controlled by the valve in the pre-control circuit.
If several heating circuits have the same flow set point, the heating circuit with lowest number al-
ways has priority and is controlled by the primary valve.
5.2 Weather-compensated control
When weather-compensated control is used, the flow temperature is controlled according to the
outdoor temperature. The heating characteristic in the controller defines the flow temperature
set point as a function of the outdoor temperature (–> Fig. 2).

Functions of the heating circuit
If just one outdoor sensor should be connected, connect it to AF1. This outdoor temperature is
then used also for HK2 and HK3.
5.2.1 Gradient characteristic
Basically, the following rule applies: a decrease in the outdoor temperature causes the flow tem-
perature to increase. By varying the Gradient and Level parameters, you can adapt the charac-
teristic to your individual requirements. Increasing Gradient results in a higher flow tempera-
ture, decreasing Gradient in a lower flow temperature. The parameter Level performs a parallel
transport of the heating characteristic in an upward or downward direction.
Outside the times-of-use, reduced set points are used for control:
Reduced flow set point = Flow set point – Set-back difference.
The Max. flow temperature and Min. flow temperature parameters mark the upper and lower lim-
its of the flow temperature. A separate gradient characteristic can be selected for the limitation
of the return flow temperature.
Examples for adjusting the characteristic:
Gradient approx. 1.8
Gradient approx. 1.4
Gradient approx. 1.0

The 4-point characteristic allows you to define your own heating characteristic.
It is defined by 4 points for the Outdoor temperature, the Flow temperature and the Return flow
temperature. The Set-back difference at points 2 and 3 indicates how much the flow temperature
is reduced outside the times-of-use.

active (Co1, 2, 3 -> Fb07 = OFF).
5.3 Fixed set point control
During the times-of-use, the flow temperature can be controlled according to a fixed set point.
Outside the times-of-use, this set point is reduced by the Set-back difference. Both Minimum
flow temperature and Maximum flow temperature parameters are set to identical values.

5.4 Differential temperature control using variable weighting factors
This function allows the return flow temperature to be taken into account in addition to the flow
temperature. It can only be used in heating circuits with mixing valves.
The difference between the flow and return flow temperature is specified using the Intended
temperature difference parameter. It is a measure for the energy consumption in a heating cir-
cuit. The greater the temperature difference, the larger the energy required by a heating circuit.
If the actual temperature difference is not the same as the intended temperature difference, it is
evaluated by the Kp factor for differential temperature control. After initial signs for a deviation
occur, the flow temperature is raised or reduced by this factor.
When the Kp factor for differential temperature control is set to 0, the return flow temperature
does not have any affect on the control of the flow temperature.
When the Kp factor for differential temperature control is set to 1, a pure return flow tempera-
ture limitation takes place (–> section 7.4).
The reset time TN determines how fast the deviation of the temperature difference affects the
control circuit (the larger TN is, the slower the rate in change).
The Intended temperature difference parameter is maintained at a constant value by adjusting
the speed of the associated circulation pump in the heating circuit. The pump is controlled by an
analog 0 to 10 V signal, which is applied to the associated analog output (AA) of the controller
(AA1 to AA3). The control signal is displayed in the associated info level. When the differential
temperature control without return flow limitation is active, the actual temperature of the return
flow is nevertheless displayed. After pressing the enter key, the set point is displayed together
with the string "S-r" (for differential temperature control using variable weighting factors).

5.5 Deactivation depending on outdoor temperature
5.5.1 OT deactivation value in rated operation
If the outdoor temperature exceeds the limit OT deactivation value in rated operation, the affected
heating circuit is put out of service immediately. The valve is closed and the pump is switched off
after t = 2 x Valve transit time. When the outdoor temperature falls below this value (less 0.5 °C
hysteresis), heating operation is restarted immediately.
With the default settings, this means that, during the warm season, the system is switched off at an
outdoor temperature of 22 °C.

Functions of the heating circuit
When the outdoor temperature falls below this value (less 0.5 °C hysteresis), heating operation is
restarted immediately.
With the default settings, this means that, at night, the system is switched off at an outdoor tem-
perature of 10 °C to save energy. Nevertheless, remember that the system requires some time in
the morning to heat up the building (–> Outdoor temperature-dependent advance heating,
section 5.7).

If a heating circuit is in reduced operation (automatic mode), the circuit is automatically trans-
ferred to rated operation when the outdoor temperature falls below the limit OT activation value
in rated operation. When the limit value is exceeded (plus 0.5 °C hysteresis), reduced operation
is restarted.
This function is activated at very low temperatures to avoid the building cooling down exces-
sively outside the times-of-use when low outdoor temperatures occur.

5.5.4 Summer mode
Summer mode is activated depending on the mean daytime temperature (measured between
7.00h and 22.00h) during the desired period.
If the mean daytime temperature exceeds the Outdoor temperature limit in summer mode on
two consecutive days, summer mode is activated on the following day: the heating is switched
off. If the mean daytime temperature remains below the Outdoor temperature limit in summer
mode on the next day, summer mode is deactivated on the following day.

Note!
Summer mode only becomes effective when the controller is in automatic mode ( ).
5.6 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 decreases, or increases and de-
creases. 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 small
12°C
steps. Assuming a Delay of 3 °C/h, the adaptation would take t =
= 4 h.
3°C /h
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 di-
rect sunshine.
In the operating level, the outdoor temperature blinks on the display while delayed outdoor tem-
perature adaptation is active. The calculated outdoor temperature is displayed.

Functions of the heating circuit
5.8 Remote operation
Apart from measuring the room temperature, the Type 5244 Room Sensor (PTC sensor) and
Type 5257-5 Room Sensor (Pt 1000 sensor) offer the following options to influence the control
process:
Automatic mode · Day mode · Night mode
4 Set point correction: during rated operation, the room temperature set point can be in-
4 Selection of the operating mode:
creased or reduced by up to 5 °C using a continuously adjustable rotary knob.
When the room sensor is activated, the measured room temperature is displayed. Nevertheless,
it is not used for control unless the Optimization, Adaptation, Flash adaptation or Room tem-
perature-dependent control functions have been activated.

5.9 Optimization with room sensor
Both the following described functions should only be used when the room (reference room) in
which the room sensor is located has a typical heating pattern similar to the rest of the building.
In addition, there should be no thermostat valves mounted on the radiators in this reference
room.

Functions of the DHW circuit
There are two types of optimization depending on the activation conditions:
4 Outdoor temperature-dependent advance heating, room temperature-dependent deacti-
vation
The controller activates the heating depending on the outdoor temperature before the
time-of-use starts in normal operation. The Advance heating time is based on an outdoor
temperature of –12 °C. The advance heating time is shorter when the outdoor temperature is
higher (see section 5.7).
4 Room temperature-dependent advance heating and deactivation
The controller calculates the required advance heating time (max. 6 hours) adapted to the
building characteristics, resulting in the Day set point (rated room temperature) being
reached in the reference room when the time-of-use starts. The heating is heated with the
maximum flow temperature during the advance heating phase. As soon as the Day set point
is reached, weather-compensated control starts.
The controller deactivates the heating in both types of optimization depending on the room sen-
sors up to two hours before the time-of-use finishes. The controller chooses the deactivation time
such that the room temperature does not drop significantly below the desired temperature until
the time-of-use ends.
During the advance heating period and the premature deactivation of the heating system, the
icons
or
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 premature de-
activation of the heating system.
When the room temperature decreases while the heating system is temporarily outside its
times-of-use, this can prematurely cause the controller to heat up to the adjusted Room set point.

reference room, where the room sensor is located, represents the entire building and is moni-
tored to ensure that the Day set point is maintained. When the mean measured room tempera-
ture in rated operation deviates from the adjusted set point, the heating characteristic is modi-
fied accordingly for the following time-of-use. The corrected value is displayed in PA1, 2, 3 pa-

5.12 Room temperature-dependent control
In systems Anl 6 and 9, the Room temperature-dependent control function can be separately
activated for each heating circuit. The Room sensor function must be activated for this function.
Flow and return flow sensors only serve to display the temperature and can therefore be deacti-
vated.
The outdoor sensors are not required for the room control function, but are still required for the
Frost protection function. The outdoor sensor AF1 can also be deactivated if all the control cir-
cuits are configured as room control circuits.
Activation of the room control function causes the control parameters to be automatically set to
the following settings:
TN (reset time) = 1617 s, TV (derivative-action time) = 330 s, KP (proportional gain) = 20
With the aid of Parameter optimization (Co1, 2, 3 -> Fb16 = ON), these settings are opti-
mized. This, however, requires a constant room temperature at the time when the function is ac-
tivated and a temperature difference between the current room temperature and the new room
set point of at least 3 °C.
In room control circuits, the heating circuit pump is switched on during the advance heating
phase.
Note!
A fictive flow set point is reported to master controller in case there is a demand for an exter-
nally required signal when the room control function is active. This set point is calculated from
the characteristic and outdoor temperature and adapted to the actual demand over adaptation
and flash adaptation.
The fictive flow set point has no effect on mixer circuits and blinks on the display. Just the third
type of optimization is permitted when the room control is active.
!
Note! The frost protection cannot function without an outdoor sensor.

5.13 Pump management
To control the circulation pumps for the heating circuits (UP1 and UP2), reed relay outputs can
be used instead of the relay output. Depending on the operating state, the circulation pumps run
during the times-of-use regulated depending on the differential pressure. The differential pres-
sure is regulated by the pumps. Outside the times-of-use the circulation pumps are switched
back to the minimum speed. The binary outputs BA1 to BA4 have the following function:
4 BA1, BA3: Circulation pump on and off
4 BA2, BA4: Reduce pump speed
If the circulation pump is to be switched on, the contact of BA1 or BA3 is closed. The binary out-
puts BA2 and BA4 can be configured over the function blocks Co1, 2 -> Fb13.

Fig. 5 · DHW heating in a storage tank charging system
Start storage tank charging
The controller begins charging the storage tank when the water temperature measured at sen-
sor SF1 falls below the DHW demand ON by 0.1 °C. If the flow temperature in the system is
higher than the required charging temperature, the controller attempts to reduce it in the heat-
ing circuit for maximum 3 minutes before the heat exchanger pump together with the storage
tank charging pump start to run.
When there is no heating operation or when the flow temperature in the system is lower, the
heat exchanger charging pump is switched on immediately. The storage tank charging pump is
switched on when the temperature currently measured at storage sensor VFT has reached the
temperature measured at sensor SF1.
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 sensor VFT.
Note!
The charging temperature VFT is regulated by the primary valve in system Anl 2. In systems
Anl 4, 5 and 10, the charging temperature VFT is only regulated by the primary valve when the
DHW demand has the highest set point and has priority.
In all other systems (Anl 7, 8 and 9) the mixing valve regulates the charging temperature VFT.
When the Circulation pump function is active, the circulation pump remains in operation ac-
cording to the time schedule. The pump is switched off when this function is deactivated.

System-wide functions
The Mixing valve always active function allows the heat exchanger to maintain the charging
temperature using the mixing valve. The heat exchanger charging pump remains switched on
and the return flow temperature is not limited outside the times-of-use.
When the flow sensor VFS is active, the set point in the heat exchanger charging circuit is af-
fected by the system deviation in the storage tank charging circuit when the storage tank charg-
ing pump is switched on:
If the temperature measured at the flow sensor is smaller than the required charging tempera-
ture, the set point in the heat exchanger charging circuit is raised by 1 °C every minute.
If the set point in the heat exchanger charging circuit reaches the value in Maximum charging
temperature parameter, it is not raised any further; an Err 10 alarm is generated.
Stop storage tank charging
The controller stops charging the storage tank when the water temperature in the storage tank
measured at sensor SF2 (DHW demand OFF) exceeds the set point by 0.1 °C. The primary
valve (Anl 2) or the mixing valve in the DHW circuit are sent pulse signals until the heat
exchanger charging temperature on the primary side at sensor VFT has fallen below the Heat
exchanger charging pump deactivation limit.
The heat exchanger charging pump is switched off according to the time schedule and depend-
ing on the temperature. When the flow set point of the primary heating circuit is lower than the
Heat exchanger charging pump deactivation limit, the heat exchanger charging pump (TLP) is
first switched off when the primary heat exchanger charging temperature at sensor VFT has
dropped to the same level as the flow set point of the primary heating circuit. The heat
exchanger charging pump is switched off at the latest after t = 2 x Transit time of the primary
valve.
The storage tank charging pump (SLP) is switched off after t = 2 x Transit time of the primary
valve or when the storage tank charging temperature in the secondary circuit at sensor VFS has
fallen below the Storage tank charging pump deactivation limit.
The circulation pump is switched on and off according to a time schedule.

Start storage tank charging
The controller can be reconfigured for all systems with DHW heating to control a DHW storage
tank with heating register (storage tank system).
The controller switches the storage tank charging pump (SLP) on and off and controls the mixing
valve for the DHW circuit. A mixing valve in the DHW circuit does not exist in system Anl 2. The
sensor VFS is connected to terminal 28 and the storage tank charging pump to terminal 45.
The controller starts the storage tank charging when the water temperature measured at sensor
SF1 falls below the DHW demand ON by 0.1 °C. If the flow temperature in the system is higher
than the required charging temperature, the controller attempts to reduce it in the heating circuit
for maximum three minutes before the storage tank charging pump starts to run.

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 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 sensor VFS.
Note!
The charging temperature VFS is controlled in system Anl 2 by the primary valve. In all the other
systems (Anl 4, 5, 7, 8, 9 and 10) the mixing valve regulates the charging temperature VFS.
When the Circulations pump function is active, the circulation pump remains in operation ac-
cording to the time schedule. The pumps is switched off when this function is deactivated.
The Mixing valve always active function allows the heat exchanger to maintain the charging
temperature using the mixing valve. The heat exchanger charging pump remains switched on
and the return flow temperature is not limited outside the times-of-use.
Stop storage tank charging
The controller stops charging the storage tank when the water temperature in the storage tank
measured at sensor SF1 exceeds the temperature T = Charging temperature + Hysteresis by
0.1 °C. 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 when the charging temperature at sensor VFS
has fallen below the Storage tank charging pump deactivation limit; however, at the latest, af-
ter t = 2 x Transit time of the primary valve.
In the default setting, the storage tank is charged by 5 °C to at least 50 °C when the storage tank
temperature falls below 40 °C. The charging temperature is 55 °C. On completing the storage
tank charging, the heating valve is closed and the charging pump continues to run until the
charging temperature falls below 50 °C.

6.3 Priority operation
In many district heating systems with primary DHW heating, the allotted amount of water is only
intended to supply the heating system. 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
heating has been concluded.
Nevertheless, heating operation is not to be simply interrupted. Only the amount of energy re-
quired for DHW heating is to be deducted. This can be achieved by using the priority functions
Reverse control and Set-back operation.
6.3.1 Reverse control
In all systems with DHW heating and at least one heating circuit with a control valve, the DHW
heating can be given priority by applying a reverse control. With the setting Co4 -> Fb06 =
ON, the charging temperature can be monitored. If the temperature also falls below the charg-
ing temperature after the time period set in function block Fb07 has elapsed, the heating circuit
is closed and the set point remains the same.
Which circuit is closed depends on how the system (Anl) is configured:
Heating circuit with the highest flow set point

6.4 Forced charging of the DHW storage tank
To provide the full room heating performance when the time-of-use of the heating circuits be-
gins, existing 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
demand ON + Hysteresis. The forced charging of the storage tank does not take place when the
DHW circuit is not activated 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.
6.5 Thermal disinfection of the DHW storage tank
In all systems with DHW heating, the DHW storage tank is thermally disinfected on a selected
Day of the week (1 to 7) or every day (0). The storage tank is heated up to the adjusted Disinfec-
tion temperature. The charging set point is always higher than the Disinfection temperature by
the value in Charging boost. Disinfection begins at the adjusted Start time and, at the latest,
ends at the specified Stop time.
When the Disinfection temperature has not been reached at the end of the thermal disinfection
cycle, an ERR-2 alarm is generated and

on the display. If
the outdoor temperature drops below 0 °C, the heating and circulation pumps are activated.
The DHW storage tank is charged to 10 °C.
7.3 Forced operation of the pumps
When the heating circuit pumps have not been activated for 24 hours, forced operation of the
pumps is started between 12.00h and 12.01h. This is done to avoid that the pumps get stuck
when they are not operated for a longer period of time. The forced operation of the storage tank
or heat exchanger charging pump is operated between 12.01h and 12.02h.
7.4 Return flow temperature limitation
The temperature difference between the flow and return flow 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 preset. The return flow tem-
perature can be limited either to a value depending on the outdoor temperature (variable) or to
a fixed set point.
When the temperature measured at return flow sensor RüF exceeds the Limitation factor, the set
point of the flow temperature (flow temperature of the heating system, charging temperature) is
reduced. As a result, the primary flow rate is reduced and the return flow temperature falls. The
set point reading (flow temperature of the heating system, charging temperature) blinks to indi-
cate that a return flow limitation is active.

7.5 Condensate accumulation control
Activate the Condensate accumulation control 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.
In systems Anl 6 and 9, the limitation applies to all control valves; in all other systems, it applies
to the control valve with the highest flow temperature set point.
In systems with DHW heating on the primary side (Anl 7 and 8), the Condensate accumulation

7.6 Compensating for time delays
The controller regulates the control circuit with the highest flow set point with the secondary flow
sensor. If the sensor is placed on the secondary side directly downstream of the heat exchanger
and the setting Co5 -> Fb06 = ON configured, any time delays due to changes in temperature
at a distant flow sensor do not occur anymore. This measure used with a condensate accumula-
tion control means that the control can intervene before the control valve releases

7.7 Three-step control
The flow temperature can be controlled using a PI algorithm. The valve reacts to pulses that the
controller emits when a system deviation occurs. The length of the first pulse, in particular, de-
pends on the extent of the system deviation and the selected Proportional gain KP (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 in-
fluenced by the Reset time TN (the pause length increases as TN increases).
The Transit time TY specifies the time required by the valve to travel through the range of 0 to
100 %.
The three-step control can be configured separately for individual heating circuits, for the DHW
heating and for the pre-control circuit.

7.8 On/off control
The flow temperature can be controlled by an on/off signal. The controlled valve is opened
when the flow temperature falls below the set point by T = 0.5 x Hysteresis. When the flow tem-
perature exceeds the set point by T = 0.5 x Hysteresis, the control valve is closed. The greater the
Hysteresis selected, the lower the switching frequency. The UP lag time parameter indicates the
time span which the circulation pump continues to run after the control valve is closed (the pa-
rameter only needs to be set for the heating circuits HK1, HK2 and HK3).
By entering Minimum activation time, a burner once switched on remains switched on for the
time entered, regardless of how the temperature develops. Likewise, a burner that has been
switched off due to the temperatures remains switched off for the time entered in Minimum de-
activation time.
The on/off control can be configured separately for the individual heating circuits and for the
pre-control circuit.

7.9 Continuous-action control
The flow temperature can be controlled using a PID algorithm. The valve receives an analog 0 to
10 V signal issued by the controller. The proportional-action component causes an immediate
change in the 0 to 10 V signal when a system deviation arises (the larger the KP, the greater the
change). The integral-action component first affects the control after a certain time: TN stands
for the time that passes until the I-action component has changed the output signal so far as the
P-action component just did (the larger the TN, the slower the rate in change). The D-action com-
ponent causes every change in system deviation to have any increased effect on the output sig-
nal (the larger the TV, the more intensified the change).
The continuous-action control can be configured separately for individual heating circuits, for
the DHW heating and for the pre-control circuit.

7.11 Flow rate/capacity limitation over a pulse input
Flow rate/capacity limitation can be implemented based on a pulse signal.
There are three different operating situations:
4 A system with simultaneous room heating and DHW heating requires maximum energy.
4 A system with a fully charged storage tank which performs only room heating requires less
energy.
4 A system which suspends room heating during DHW heating requires less energy.
As a result, three different maximum limit values can be specified:
4 Max. limit value to determine the absolute upper limit
4 Max. limit value for heating for exclusive operation of the room heating
4 Max. limit value for DHW for exclusive operation of the DHW heating
In all systems without DHW heating, only the Max. limit value for the flow rate or capacity can
be set.

System-wide functions
A heat meter with pulse output connected at input Vmax (terminal 30) can be used either to limit
the system flow rate (parameter code: U) or the system capacity (parameter code: P). The pulse
weighting of the heat meter (WMZ) and the type of limitation selected must be entered. The dis-
played value corresponds to the unit l/pulse or kWh/pulse.
When the pulse rate reaches the current maximum limit, the flow set point of the control circuit
RK1 is reduced. How strongly the controller responds is determined by the Proportional-action
coefficient for limitation.
Example to determine the limit value:
If a capacity of 30 kW is to be limited, the following limit value must be set for a heat meter with
an output of one pulse per kilowatt-hour:

set point of 50 °C or the Max. flow temperature (when the Max. flow temperature is smaller
than 50 °C).
4 Flow sensor VF: When the flow sensor is defective, the controller continues to work with the
valve in the last position.
4 Flow sensor in the DHW heat exchanger VFT: The DHW control valve is closed when the
sensor fails.
4 Flow sensor in the DHW storage tank VFS: The flow set point for the DHW heat exchanger
is only controlled with VFT. The display blinks.
4 Return sensor RüF: When the return flow sensor is defective, the controller continues to work
without the return flow temperature limitation function.

The flow temperature and the room temperature can be monitored for any deviations. This func-
tion is activated in Co5 -> Fb20. The controller issues an alarm when:
4 the flow temperature deviates from its set point by more than 10 °C for more than 30
minutes
4 the room temperature falls below its set point by 2 °C for more than 30 minutes
4 the return flow temperature limitation is active for more than 30 minutes.
When one of these conditions occurs, the bit for the associated sensor is set in holding regis-
ter 857. A set bit in holding register HR 857 causes the bit 4 to be set in the error status register

8.4 Monitoring the input terminals for limit violations
The controller provides the option to apply limits (in % of measuring range) to two selected in-
puts (temperature sensor or analog inputs) and to issue an alert to a higher-level control system
by writing in the error status register. Directly after setting the function block, select the terminal
that is to be monitored and the condition that triggers the alarm according to the following
codes:
4 Alarm when upper limit is exceeded (OGW)
Lower limit: 0 %
Upper limit: Any
4 Alarm when bottom limit is not reached (UGW)
Lower limit: Any
Upper limit: 100 %
4 Alarm when the limits is exceeded or not reached
Lower limit: > 0 % < OGW
Upper limit: > UGW < 100 %
4 Alarm ON, when UGW is exceeded and alarm OFF when OGW is not reached
Lower limit: > OGW < 100 %
Upper limit: > 0 % < UGW
Input to which temperature sensors are connected have readings in °C (measuring range from
–30 to 160 °C); analog input readings are shown in % of the measuring range.
In systems Anl 1, 3, 4, 6, 7 and 10, the limit alarm is made with “BA EIN“ over an analog relay.
A make contact or break contact function can be assigned to the relay by selecting “STEIG“ (=
rising signal edge) and “FALL“ (= negative signal edge) respectively. The limit alarm also ap-
pears in the error status register by selecting “Fsr-E”.
Note!
The associated binary output is marked in the wiring plan with GWx and GWy and depends on

8.5 Error status register
The HR 60 and HR 61 error status registers (holding register - 16-bit) are used to indicate con-
troller or system errors. HR 60 contains general alarms, whereas special faults are entered in
HR 61. In modem mode (Co9 -> Fb01 = ON), the change in state of HR 60 or HR 61 causes the
controller to dial the control system.
In InF8 level the bits of the error status register are displayed:
4 FSR1 (general error):
The corresponding block at the top is set for every bit set
4 FSR2 (special error):
by pressing
key, the set bits are displayed similar to FSr1
In both cases, the blocks 20 to 23 are visible when a bit is set in another error status register
(which is currently not visible) to make it immediately recognizable whether one of the maxi-
mum 32 error flags has been set.

Communication
Using the serial system bus interface, the TROVIS 5179 District Heating Controller can commu-
nicate with a building control system. In combination with a suitable software for process visual-
ization and communication, a complete control system can be implemented.
The following communication settings are possible:
– Operation with a dial-up modem at the RS-232-C system bus interface
Basically, communication is only established automatically when errors occur. 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. We recommend to use the modem connect-
ing cable (1400-7139).
– Operation with a leased line modem at the RS-232-C system bus interface
Communication is established via a permanent connection between two leased line modems.
This setup is applied for long-distance transmissions or when different signal level converters
are used. The connection between controller and modem can also be established via the mo-
dem connecting cable (1400-7139).
– Operation at a four-wire bus
To establish the link between controller and bus line, the signal level needs to be converted by a
converter (SAMSON’s cable converter 1400-7308).

Fig. 8 · Pin assignment of RJ-12 system bus interface
9.1 RS-232-C system bus interface
The system bus connection is located at the back of the controller housing (RJ-12 jack).
In this case, the controller can be connected either directly to the serial interface of a PC
(point-to-point connection) or to a (dial-up) modem. A dial-up modem is required if the control-
ler is to be connected to the telecommunications network. In this case, the controller works au-
tonomously and can issue an alarm call to the building control station when errors occur. Addi-
tionally, the building control station can dial up the controller, read data from it, and send new
data once the valid key number has been written to the holding register no. 40070.
On recognizing the key code from the controller as valid, the register value “1” confirms writing
permission. In any other case, the register value remains at “0”. Any further establishment of
communications requires the writing permission to be acquired by resending the key number.
Note!
If a wrong key number has been written to holding register no. 40070 for the third consecutive
time, the controller immediately interrupts the modem connection and sets the D6 bit of the error
status register (Unauthorized access). As a result, the call to the configured control system is
triggered or a text message/fax 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 of faults. Using
the Dial-up also upon corrected fault function, the controller additionally informs the building
control station when a previously registered fault no longer persists.

9.2 RS-232/RS-485 system bus interface (for four-wire bus) in combina-
tion with cable converters
A constant bus connection is required (data cable) for operation of the district heating controller
in conjunction with cable converters. The bus line is routed to the individual control instruments
in an open ring. At the end of the bus line, the data cable is connected to the control station us-
ing an RS-485/RS-232 converter (e.g. TROVIS 5484). The maximum range of the bus connec-
tion (cable length) is 1,200 meters. A maximum of 32 devices can be connected to such a seg-
ment. If you wish to use more than 32 devices in line or need to bridge greater distances, make
sure repeaters (e.g. TROVIS 5482) are installed to replicate the signal. With 8-bit addressing, a
maximum of 246 devices can be addressed and connected to a bus.

Warning!
You are required to follow the relevant standards and regulations concerning lightning and
overvoltage protection on installation.

9.3 Description of communication parameters to be adjusted
Station address (ST.-NR)
This address is used to identify the district heating controller in bus or modem mode. In a system,
each controller needs to be assigned a unique address.
Baud rate (BAUD)
In a bus system, the baud rate refers to the transfer speed between control system and district
heating controller. In modem mode, baud rate refers to the transfer speed between district heat-
ing controller and modem.
The baud rate adjusted at the district heating controller must correspond with the baud rate of
the control system, otherwise communication cannot be established.
Cyclic initialization (I)
This parameter defines the period of time for a cyclical issue of the initialization command
“ATZ“. The command is not issued during dial-up or when connected. “ATZ“ causes the con-
figuration profile 0 to be copied to the active profile, provided the modem parameters have
been set and saved in profile 0 using a suitable terminal program.
Typical initialization of a modem with a terminal program:
AT & F
OK
(restores modem to its factory settings)
(response of the modem)
ATEOSO = 1 (command input, EO: echo off;
SO = 1: answer on first ring)
Modem dialing pause (P)
It is recommended to observe an interval of approx. 3 to 5 minutes between dialing up to the
control system/or sending a text message or fax to avoid a permanent overloading of the (tele-
communications) network. The modem dialing pause is the interval between two dialing at-
tempts.

Communication
Modem timeout (t)
When the controller connects to the GLT but without addressing a Modbus data point, the con-
nection is closed after the time specified for Modem time-out has elapsed. If the error status reg-
ister has not been read during the GLT connection, the controller dials up to the GLT again after
the Modem dialing pause (P) has elapsed.
Number of redialing attempts (C)
The controller tries to dial up to the control system again, observing the Modem dialing pause,
in case the control station/text messaging center/fax 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, the district heating controller dials up the alternative recipient.
Resetting of triggered call = Reading the error status register (HR 40060)
Phone number of control station (tELno)
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)
Phone number of the alternative recipient (rESno)
Enter the phone number of the alternative recipient 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, 1 sec. pause, 654321“: 0 6 9 P 6 5 4 3 2 1 – (= 10 characters)

Note!
The initialization settings described here are indispensable for operation on a dial-up modem.
Nevertheless, it cannot be guaranteed that data are transferred after the initialization settings
have been adjusted. Due to the broad range of modems available on the market and the differ-
ent commands, refer to the operating manual of the modem for further details.
9.4 Meter bus interface
The district heating controller can communicate with up to 3 heat and water meters according to
EN 1434-3.
Details on the use of the different heat or water meters can be found in the technical documenta-
tion TV-SK 6311.
9.4.1 Activating the meter bus
To successfully transfer data from the heat meter (WMZ) to the district heating controller, 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 or water meters are available
in Co9 -> Fb21 to Fb23. The meter bus address, model code and reading mode need to be set
in sequence. A meter bus address must be unique and correspond with the address preset 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 approx. every 24 hours (24h), continuously (con) or
when the coils (= Modbus data points) assigned to the heat meters WMZ1 to WMZ3 are overwrit-
ten with the value 1 (CoiL) via the system bus interface.
In InF9 info level, “1434“ is displayed when the meter bus is activated. Press the enter key to get
to the display referring to the meter bus. For each of the three heat meters whose address is
not 255, “buSi“ (with i = 1, 2, 3) is indicated. Press the enter key again to display the following

Flow rate and/or capacity limitation with the aid of the connected meter bus can be imple-
mented by selecting the type of limitation 2, 3 or 4. The update rate of the measured variable,
flow rate and/or capacity, must be smaller than 5 seconds in meter bus operation to carry out a
proper limitation. Refer to the technical documentation TV-SK 6311 for details on which listed
heat meters fulfill this criterion and can be used for limitation purposes. In case of battery-oper-
ated heat meters in particular, please note that some makes react with communication intervals
if they are polled too frequently. Other makes could use up their batteries too quickly. The tech-
nical documentation TV-SK 6311 provides more details on these matters.

4 A system with simultaneous room heating and DHW heating requires maximum energy.
4 A system with a fully charged storage tank which performs only room heating requires less
energy.
4 A system which suspends room heating during DHW heating requires less energy.
As a result, three different maximum limit values can be specified:
4 Max. limit value to determine the absolute upper limit
4 Max. limit value for heating for exclusive operation of the room heating
4 Max. limit value for DHW for exclusive operation of the DHW heating
In all systems without DHW heating or without heating circuit, only the Max. limit value for the

On connecting LONMARK devices, CO7 -> Fb00 = OFF needs to be configured.
Each controller is assigned a LON station address, which needs to be set in the PA7 parameter
level. A station address in a subnet must be unique. Each controller type is assigned its own
subnet. This means that identical LON station addresses can be assigned for different controller
types, e.g. 5174 and 5179, as they belong to different subnets. A maximum of 59 participants
consisting of TROVIS 5171, 5174, 5177 and 5179 can be connected together.

The controller sends its inputs and outputs as well as pulse counters and their pulse duration
over the LON network to a TROVIS 5171 Programmable Logic Controller.
The pulse inputs are sent after four minutes; the sensor temperatures when the temperature has
changed by at least 1 °C or after four minutes at the latest. The analog inputs and outputs are
sent when the signal level changes by 0.5 V. The binary inputs and outputs are sent after every
change or after four minutes at the latest.
In the InF7 level, all other TROVIS 5100 network participants are listed together with controller

temperature set point. In all other systems, the setting Co5 -> Fb00 = ON must be configured.
Processing an external demand
The master controller receives the demand of connected controllers over the LON network and
makes the required energy available for all the control circuits. The secondary flow sensor in-
stalled directly downstream of the heat exchanger serves as the sensor for the primary valve.
The Boost parameter improves the control performance of the connected heating circuit valves
and compensates for any loss in capacity.
If an internal heating circuit has the highest set point, the primary valve regulates the tempera-
ture at the flow collector to the set point of the heating circuit plus Boost.
The set point in the heating circuit is regulated by the mixing valve of the heating circuit. In InF5
level, the set point of the primary valve appears on the display in this case.
Note! In systems Anl 6 and 9, the external demand is only sent and not processed.

controller that can send alarms over a modem.
9.7 Sending outdoor temperatures and controller time
Two outdoor temperatures and the controller time can be sent over the LON bus which are taken
on by all the other controllers. Any controller in the system can send these data. Either all the
data can be sent by one controller or each piece of data can come from a separate controller.
The controller time and the outdoor temperature are transmitted every four minutes. The out-
door temperature is additionally transmitted if it changes by 0.5 °C. All controllers delete the
values received over the bus ten minutes after the last update.
Sending the controller time
The controller time can be made available to all LON participants. They download the transmit-
ted time and adopt it. The controller time can be sent with the setting Co7 -> Fb02 = ON. This

Caution!
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 electri-
cal work is performed by trained and experienced personnel!
Notes on installing the electrical connections
4 Install the 230 V power supply lines and the signal lines separately! To increase noise immu-
nity, observe a minimum distance of 10 cm between the lines. Make sure the minimum dis-
tance is also observed when the lines are installed in a cabinet.
4 The lines for digital signals (bus lines) and analog signals (sensor lines, analog outputs) must
also be installed separately!
4 In plants with a high electromagnetic noise level, we recommend to use 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 cable ≥10 mm² using the shortest route.
4 Inductances in the control cabinet, e.g. contactor coils, are to be equipped with suitable in-
terference suppressors (RC elements).
4 Control cabinet elements with high field strength, e.g. transformers or frequency converters,
should be shielded with separators providing a good ground connection.
Overvoltage protection
4 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!
4 The shield of signal lines installed outside buildings must have current conducting capacity
and must be grounded on both sides.
4 Surge diverters must be installed at the control cabinet inlet.
Connecting the controller
The controller is connected as illustrated in the following wiring diagrams.
If individual inputs for other functions, e.g. for binary inputs, are to be used, they must be deter-
mined in the configuration levels (Co1 to Co6).
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 rear part of the housing and fit suitable cable
glands.
