6 Functions of the heating circuit

Which controller functions are available depends on the selected system number (Anl).

6.1 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). The outdoor temperature required for weather-compensated control can either be measured at an outdoor sensor or received us

ing 0 to 10 V at UI1 input.

6.1.1 Gradient characteristic

Basically, the following rule applies: a decrease in the outdoor temperature causes the flow tem

perature to increase. By varying the parameters

Gradient and Level, you can adapt the characteristic to your individ

ual requirements:

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

The gradient needs to be decreased if the room temperature rises when it is cold outside.

The level needs to be increased and the gradient decreased if the room temperature drops when it is mild outside.

The level needs to be decreased and the gradient increased if the room temperature rises when it is mild outside.

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 'HC1 day set point' (rated room temperature) and 'HC1 night set point' (reduced room temperature). For heating systems without room sensor, the reduced flow temperature set point is based on the 'Night set-back, flow' parameter. 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 limita

tion 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: For heating systems with room sensor and without configured influence of the room tem

perature on the control process, the room temperature settings for day (HC1 day set point) and for night (HC1 night set point) only become effective satisfactorily when the heating characteris

tic has been adapted to the building/heating surface layout.

6.1.2 Four-point characteristic

The four-point characteristic allows you to define your own heating characteristic. It is defined by four points for 'Outdoor temperature', 'Flow temperature', 'Reduced flow temper

ature' and 'Return flow temperature'. The 'Max. flow temperature' and 'Min. flow temperature' pa

rameters mark the upper and lower limits of the flow temperature.

Note:

–

The HC1 flow temperature set points can be raised or reduced by 2 K in four stages even when the four-point characteristic is selected. The room temperature set points for day and night must be set (→Section 3.1) if the supplementary functions, such as Optimiza

tion or Flash adaptation (the room temperature must be measured for both these func

tions), are configured.

–

The four-point characteristic function can only be activated when the Adaptation function is not active.

6.3 Underfloor heating/drying of jointless floors

Underfloor heating

The function block setting HC1–CO1–05 = ON defines heating circuit HC1 as an underfloor heating circuit. This causes the controller at first to only restrict the value ranges for the heating characteristic gradient and the maximum flow temperature in parameter level PA1:

Flow gradient (HC1–PA1–01): 0.2 to 1.0

Max. flow temperature (HC1–PA1–07): 5.0 to 50.0 °C

Drying of jointless floors

The function block parameters are required for the drying of jointless floors. They determine the drying process: the first heating up phase starts at the entered 'Start temperature for drying of jointless floors', 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 'Temperature increase for drying of jointless floors' i.e. the default setting causes the flow temperature set point to rise to 30 °C. If the 'Max. temperature for drying of jointless floors' is reached, it is kept constant for the number of days entered in 'Max. temperature sustaining time for drying of jointless floors'. 'Temperature reduction for drying of jointless floors' determines the temperature reduction downwards. When temperature reduction is set to 0, the temperature maintaining phase moves directly to the automatic mode. By setting 'Start drying of jointless floors' to '1', the drying of jointless floors function is started. The restarting points 2 and 3 can beselected to continue an interrupted drying process.

The drying process can be followed in the information level: in the Control loop overview menu item, the messages "Jointl. floors (heating up)" is indicated during heating up, "Jointl. floors (heating)" during the maximum temperature sustaining phase and "Jointl. floors (cooling)" while the temperature is reduced. If the flow temperature deviates by more than 5 °C for over 30 minutes while the drying process is taking place, "Jointl. floors (error)" is displayed after drying has been completed. Proper drying is indicated by "Jointl. floors (end)". Any power failure that occurs while the function is running automatically restarts the drying function.

In systems in which the drying function had to be interrupted due to DHW heating (e.g. system Anl 2.0.0), storage tank charging does not occur while the drying function is active, provided it is not used for frost protection of the storage tank.

NOTICE

The function block parameters can only be accessed when the function has started by deactivat

ing the function block and activating it again.

6.4 Deactivation based on the outdoor temperature

6.4.1 HC deactivation value (day)

If the outdoor temperature exceeds 'HC1 deactivation value (day)', the heating circuit is immediately deactivated. 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), heatingoperation is restarted immediately.

The default setting causes the system to be deactivated during the warm season when the out

door temperature reaches 22.0 °C.

Parameter WE Parameter settings HC1 deactivation value (day) 22.0 °C Refer to section 3.1

6.4.2 HC deactivation value (night)

If the outdoor temperature exceeds 'HC1 deactivationvalue (night)' outside the times-of-use, the heating circuit is immediately deactivated. 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 hyster

esis), heating operation is restarted immediately. The default setting causes the system to be deactivated when the outdoor temperature reaches

15.0 °C at night to save energy. However, it is important tor remember that the system requires some time in the morning to heat up the building.

6.4.3 Outdoor temperature for continuous rated operation (day)

If a heating circuit is in reduced operation (automatic mode), the circuit is automatically switched to rated operation (day mode) when the outdoor temperature falls below 'Outdoor temperature for continuous rated operation (day)'. 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 outdoor temperatures are low.

6.4.4 Summer mode

Summer mode is activated depending on the mean daytime temperature (measured between

7.00 h and 22.00 h) during the desired period ('Earliest start date for summer mode' to 'Latest stop date for summer mode'). If the mean daytime temperature exceeds the limit entered in 'Outdoor temperature for summer mode' on the number of successive days determined in 'Delay of summer mode active' parameter, summer mode is activated on the following day: the valves of all heating circuits are closed and the heating pumps are switched off after t = 2 x valve transit time. If the mean daytime temperature remains below the limit entered in 'Outdoor temperature for summer mode' on the number of successive days determined in 'Delay of heating mode active', summer mode is deactivated on the following day.

6.5 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, increases or in

creases and decreases. 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 tem

perature in small steps. Assuming a delay of 3 °C/h,the adaptation would take

Note: The delayed outdoor temperature adaptation helps avoid unnecessary overloads of cen

tral 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.

6.6 Remote operation

Besides measuring the room temperature, the Type 5257-5 Room Panel (Pt 1000, refer to Sec

tion 11 for electrical connection) offers the following options to influence the control process:

Selection of the operating mode: – Automatic mode

– Day mode – Night mode

Set point correction: during rated operation (day mode), the room temperature set point can be increased or reduced by up to 5 °C or by up to 8 °C when the four-point characteristic function is selected at the continuously adjustable rotary knob

When the room sensor is activated, the measured room temperature is displayed when the re

mote operation is connected and activated. However, it is not used for control unless the Optimi

zation based on room temperature or Flash adaptation functions have been activated.

6.7.1 Optimization based on outdoor temperature

This function requires the use of an outdoor sensor.

The controller activates the heating based on the outdoor temperature before the time-of-use in day mode. The 'Preheating time' is based on an outdoor temperature of –12 °C. This preheating time is shortened when the outdoor temperature is higher. The colder it is outside, the earlier the night set-back finishes to ensure that the selected 'HC1 day set point' is reached as close as possible to the time when the time-of-use starts.

6.7.2 Optimization based on room temperature

This function requires the use of a room sensor. The room in which the room sensor is located (reference room) should have a similar heating characteristic to the rest of the building. In addi

tion, this reference room must not have any radiators with thermostatic valves.

Depending on the building characteristics, the controller determines and adapts the required preheating time (maximum 8 hours) to ensure that the desired 'HC1 day set point' (rated room temperature) has been reached in the reference room when the time-of-use starts. This temper

ature is built up in steps of 10 °C. As soon as the 'HC1 day set point' has been reached, weather-compensated control is activated. Depending on the room sensors, the controller switches off the heating system up to one hour before the time-of-use ends. The controller

EB 5610 EN 63

Functions of the heating circuit

chooses the deactivation time such that the room temperature does not drop significantly below the desired value before the time-of-use ends.

Outside the times-of-use, the controller monitors the 'HC1 night set point' (reduced room tem

perature). 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 prema

ture deactivation 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 'HC1 day set point'.

The controller activates the heating based on the outdoor temperature before the time-of-use in day mode. The 'Preheating time' is based on an outdoor temperature of –12 °C.

6.8 Flash adaptation

To ensure that the controller reacts immediately to room temperature deviations during day or night mode, the function block setting HC1–CO1–09 = ON must be made. The heating is then always switched off as soon as the room temperature exceeds 'HC1 day set point' or 'HC1 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 settings for 'Cycle time' and 'Gain' are not set to 0. The 'Cycle time' determines the intervals at which the flow temperature set point is corrected by 1 °C. 'Gain' set to a value other than 0 causes a direct increase/de

crease in flow temperature set point when a sudden deviation in room temperature arises. We recommend setting 'Gain' to 10.0.

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!

The controller is capable of automatically adapting the heating characteristic to the building characteristics, provided a gradient characteristic has been set (HC1–CO1–11 = OFF). The ref

erence room, where the room sensor is located, represents the entire building and is monitored to ensure that the room set point ('HC1 day set point') is maintained. When the measured mean room temperature in day mode deviates from the adjusted set point, the heating characteristic is modified accordingly for the next time-of-use.

7 Functions of the DHW circuit

7.1 DHW heating in the storage tank system

Start storage tank charging

The controller begins charging the storage tank when the water temperature measured at sensor S7 falls below 'DHW day set point' by 0.1 °C. When no heating operation takes place, the storage tank charging pump P3 is switched on immediately. If the flow temperature in the system is higher than the desired charging temperature (= 'DHW day set point' + 'Charging temperature boost'), the controller tries to reduce the flow tempera

ture in the heating circuit for up to five minutes before the storage tank charging pump P3 is acti

vated. If the flow temperature in the system is lower than the desired charging temperature, the control

ler tries to build up the flow temperature in the heating circuit for up to five minutes before the storage tank charging pump P3 is activated.

If the function DHW–CO4–16 = ON (SLP not ON unless return flow hot) is activated, the pri

mary valve is opened without simultaneously operating the storage tank charging pump P3. The storage tank charging pump P3 is not switched on before the primary return flow temperature has reached the temperature currently measured at storage tank sensor S7. This function en

ables 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.

Note: The storage tank charging temperatures are adjusted instead of the storage tank temper

atures in the menu item for DHW set points when a storage tank thermostat is used.

Time-controlled switchover of storage tank sensors

By configuring a second storage tank sensor S8 over the function block DHW–CO4–19 = ON, it is possible to determine that the storage tank sensor S7 is used for day mode in the DHW cir

cuit and that the storage tank sensor S8 is used 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 day set point' and 'DHW night set point' differ from one an

other.

Stop storage tank charging

The controller stops charging the storage tank when the water temperature measured at sensor S7 has reached the temperature T = 'DHW day set point' + 'Hysteresis'. When there is no heating operation or when the flow temperature demand in the system is lower, the correspond

ing valve is closed. The storage tank charging pump P3 is switched off after 'Lag time for storage tank charging pump' has elapsed.

The default settings cause the temperature in the storage tank is to increase by 5 °C to reach 60 °C when the storage tank temperature falls below 55 °C. The charging temperature is calculated from the 'DHW day set point' (55.0 °C) plus 'Charging temperature boost' (10.0 °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 entered in 'Lag time for storage tank charging pump'. Outside the times-of-use, the storage tank is only charged when the temperature falls below 'DHW night set point' (40.0 °C). In this case, the tank is charged with a charging temper

ature of 50 °C until 45 °C are reached in the tank.

sor S7 falls below the 'DHW day set point' by 0.1 °C. If the flow temperature in the system is higher than the desired charging temperature (= 'DHW day set point' + 'Charging temperature boost'), the controller tries to reduce the flow temperature in the heating circuit for up to fives minutes before the heat exchanger charging pump M2+ is activated together with the storage tank charging pump P3. When there is no heating operation or when the flow temperature in the system is lower, the heat exchanger charging pump M2+ is switched on immediately. If the temperature currently measured at storage tank sensor S7 is reached at the flow sensor S1, or after five minutes at the

latest, the storage tank charging pump P3 is switched on. If a storage tank thermostat is used, the storage tank charging pump P3 is switched on when the temperature T = Charging temperature – 5 °C is reached at the flow sensor S1.

Note: The storage tank charging temperatures are adjusted instead of the storage tank temper

atures in the menu item for DHW set points when a storage tank thermostat is used.

When the flow sensor S6 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 P3: if the temperature measured at flow sensor S6 is lower than the desired charging temperature, the set point in the heat exchanger circuit is increased in steps of 1 °C. When the set point in the heat exchanger charging circuit reaches the 'Max. charging tempera

ture', the set point is no longer increased. An error message 'Max. charging temperature reached' is generated.

Note: The set point in the heat exchanger circuit which is valid at the end of the charging cycle will be used again at the beginning of the next cycle.

If times-of-use have been set for DHW heating, 'DHW day set point' applies during these times-of-use. Outside the times-of-use, the 'DHW night set point' is used. This does not apply when a storage tank thermostat is used.

Time-controlled switchover of storage tank sensors

The function block setting DHW–CO4–19 = ON determines that the storage tank sensor S7 is used for day mode in the DHW circuit and that the storage tank sensor S8 is used for night mode. As a result, different storage tank volumes can be kept at a constant temperature accord

ing to a time schedule, and also at different temperatures if the 'DHW day set point' and 'DHW night set point' differ from one another.

Stop storage tank charging

The controller stops charging the storage tank when the water temperature measured at sen

sor S8 has reached the temperature T = 'DHW day set point' + 'Hysteresis'. To avoid accumu

lated heat, the heat exchanger charging pump continues to run for the time entered in 'Lag time for storage tank charging pump' when the valve closes. The storage tank charging pump P3 is switched off approx. ten seconds after the lag time of the heat exchanger charging pump.

When the Circulation return flow in heat exchanger function is active, the control process using the 'DHW day set point' remains active according to the time schedule even when the temperature T = 'DHW day set point' + 'Hysteresis' has been exceeded at storage tank sensor S8. In this way, circulation losses (even for small amounts of tapped hot water) are compensated for over the heat exchanger.

The instantaneous DHW heating system can be configured in systems Anl 1.9.0, 11.9.0 and

11.9.1.

Without a flow switch, the controller can only regulate the DHW temperature to 'Day DWH set point' during the times-of-use of the circulation pump. The flow switch allows the controller to recognize exactly when DHW is being tapped. By deleting all the time-of-uses for the circulation pump P2, it is possible to regulate the DHW temperature to 'Day DWH set point' just while the DHW is being tapping. When the tapping is finished, the valve closes and the heat exchanger charging pump P1 is switched off after a delay.

The function block setting DHW–CO4–07 = ON causes heating operating in heating circuit HC1 to be restarted for ten minutes after 20 minutes priority. The setting DHW–CO4–07 = OFF gives the storage tank charging unlimited priority over the heating operation in the UP1 heating circuit.

Functions WE Configuration Intermediate heating ON DHW–CO4–07 = ON

7.5 Parallel pump operation

This function can only be activated in systems Anl 2.1.0 and 2.2.0.

The function block setting DWW–CO4–06 = ON, the heating pump UP1 remains switched on during DHW heating unless certain operating situations occur. These situations include, for ex

ample, those when the current flow temperature demand of the pump circuit is lower than 'Min. flow set point in heating circuit for parallel pump operation'. In this case, the controller applies priority operation with intermediate heating. Once a parallel pump operation cycle has been activated and the time for 'Delay of cancelation due to system deviation' has elapsed, system deviations greater than 5 °C cause the controller to suspend parallel operation for ten minutes and to apply priority operation. By setting 'Delay of cancelation due to system deviation' to 0 min. leads to a parallel operation once initiated to remain regardless of a deviation.

Note: The Intermediate heating and Parallel pump operation functions cannot be configured simultaneously. When DHW–CO4–06 = ON is configured, DHW–CO4–07 = ON cannot be selected and vice versa.

7.7 Priority operation

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 heating has been concluded. Nevertheless, heating operation is not to be interrupted simply. 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.

7.7.1 Reverse control

In all systems with DHW heating and a heating circuit with control valve, DHW heating can be given priority by applying reverse control. The function block setting DHW–CO4–08 = ON al

lows the temperature at the flow sensor DHW to be monitored.

In systems without the flow sensor DHW, the temperature directly at the storage tank sensor is monitored. If system deviations still occur after the time entered in 'Delay of reverse control active' has elapsed, the set point of the heating circuit with control valve is gradually reduced each minute until the flow temperature set point has reached 5 °C at the minimum. How strongly the controller responds is determined by the 'Correction factor'.

7.8 Forced charging of the DHW storage tank

To provide the full room heating performance when the time-of-use of the heating circuit begins, storage tanks are charged one hour before the time-of-use of the heating circuit starts.

For the individual controller, this means that storage tank charging is activated when the water temperature in the storage tank falls below the deactivation value of T = 'DHW day set point' + '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 programmed for the heating circuit.

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

7.9 Thermal disinfection of the DHW storage tank

In all systems with DHW heating in storage tank system or in storage tank charging system, a thermal disinfection is performed on the selected 'Day of week for thermal disinfection' or daily (by selecting 8). The DHW storage tank is heated up to the adjusted 'Disinfection temperature' taking the 'Charging temperature boost' parameter (or function block parameter 'Thermal disinfection boost' depending on the system) into account. Disinfection begins at the adjusted 'Start time of thermal disinfection' and, at the latest, ends at the specified 'Stop time of thermal disinfection'. The 'Disinfection temperature sustaining time' determines how long the disinfection temperature must be maintainedwithin the adjusted time period to rate the process successful. If the 'Disinfection temperature sustaining time' is set to 0 min, no intermediate heating operation takes place during thermal disinfection.

Alternatively, the thermal disinfection can be started over an binary signal to S4. When 'Day of week for thermal disinfection' is set to 9 or 10, the start and stop times do not need to be en

tered.

When 'Day of week for thermal disinfection' is set to 9, the thermal disinfection starts when the binary input closes and stops when the binary input opens.

When 'Day of week for thermal disinfection' is set to 10, the thermal disinfection starts when the binary input opens and stops when the binary input closes.

When the 'Disinfection temperature' has not been reached before the end of the thermal disin

fection cycle, the 'Disinfection stopped' error message is generated. This error message can also be generated prematurely if the remaining time until the disinfection temperature is reached is shorter than the adjusted 'Disinfection temperature sustaining time'. The error mes

sage is automatically reset when the 'Disinfection temperature' is properly reached during the following thermal disinfection cycle.

8.2 Frost protection

Frost protection measures are taken when the outdoor temperature falls below the 'Outdoor temperature for frost protection'. The switching differential to cancel the frost protection mea

sures is always 1 °C.

Frost protection without highest priority HC1–CO5–09 = OFF (restricted frost protection): Frost protection measures are taken only when no heating operation takes place in the system. The heating 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 heating circuit of the system, if one exists, is inactive. Nevertheless, the storage tank is always recharged to 10 °C if the storage tank temperature falls below 5 °C.

Frost protection with highest priority HC1–CO5–09 = ON: The heating 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 circu

lation pump is always activated. If the storage tank temperature falls below +5 °C, the stor

age tank is recharged to +10 °C.

Note: Im stand-by mode, the frost protection symbol appears on the screen instead of when the outdoor temperature falls below the adjustable 'Outdoor temperature for frost protec

tion'.

8.3 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 12.02 h and 12.03 h. This is done to avoid that the pumps get stuck when they are not operated for a longer period 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 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 network flow temperatures are fixed to a certain temperature. The return flow temperature can be limited either to a value depending on the out

door temperature (variable) or to a fixed set point. When the temperature measured at return flow sensor exceeds the current return flow temperature limit, the set point of the flow tempera

ture (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.

In systems 2.1.0 and 2.2.0, the 'Max. return flow temperature' parameter (DHW–PA4) is used for limitation in the primary circuit during DHW heating if it is greater than the parameter valid for the primary circuit. The 'Limiting factor' determines how strongly the controller responds to limit violations (P algorithm).

If the PI action is to be implemented, configure HC1–CO5–16 = ON. This allows the integral-action component in the return flow temperature limitation algorithm of all control circuits of the controller to be activated.

NOTICE

To keep the determined return flow temperature limit, make sure that:

– the heating characteristic is not selected to be too steep – the speed of the heating pumps is not selected to be too high – the heating systems are hydronically balanced.

Note: Using weather-compensated control with gradient characteristic, the return flow temper

ature is limited to a fixed value by equating the 'Return flow temperature foot' and 'Max. return flow temperature' parameters.

tions 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, de

pends on the extent of the system deviation and the selected 'Gain KP' (the pulse length in

creases as KP increases). The pulse and pause lengths change continuously until the system de

viation has been eliminated. The pause length between the single pulses is greatly influenced by the 'Reset time TN' (the pause length increases as TN increases). The 'Valve transit time TY-OPEN' 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 flow temperature exceeds the set point by T = 0.5 x 'Hysteresis', the boiler is switched off again. The greater the value you choose for 'Hysteresis', the less the switching frequency will be. By setting the 'Min. ON time', an activated boiler remains switched on during this period regardless of the flow temperature fluctuations. Similarly, a deactivated boiler will remain switched off regardless of the flow temperature fluctuations if the 'Min. OFF time' has been specified.

8.8 Continuous control

The flow temperature can be controlled using a PID algorithm. The valve receives a 0 to 10 V signal from the controller. When a system deviation occurs, the proportional component imme

diately causes the 0 to 10 V signal to change (the greater K

, the greater the change). The inte

gral components becomes effective with time: T

represents the time which elapses until the inte

gral component has changed the output signal to the same extent as the immediate change per

formed by the proportional component (the greater T

, the slower the rate of change). Due to the derivative component, any change of the system deviation is incorporated into the output signal with a certain gain (the greater TV, the stronger the change).

8.9 Unlocking a controller/control loop 1 over the binary input

The unlocking of the control circuit or controller using the binary input only becomes effective when the control circuit or controller is in automatic mode.

An active control circuit or controller always works in automatic mode, whereas the deactivated controller behaves as if it were switched to stand-by mode. It remains active, however, in any case for processing an external demand. The controller can be unlocked over the binary input S5 when the binary input is either a make contact (switching state of the controller or control loop 1 active = 0) or a break contact (switching state of the controller or control loop 1 active = 1).

8.10 Processing an external demand

The controller can process binary or analog demands for an externally required signal by a more complex secondary system.

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 pri

mary 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 used by the primary controller. Nevertheless, if the Priority for external demand function is activated, the external demand is also processed during storage tank charging.

8.10.1 Processing an external demand with a binary signal

Regardless of the operating mode for control loop 1, except for manual mode, the flow temperature entered in 'Min. flow set point in heating circuit with active binary demand' is used in control circuit HC1 when the binary input is either a make contact (Demand switching state active =

1) or a break contact (Demand switching state active = 0).

Note: The connection of the binary input with the setting HC1–CO1–17 = ON depends on the system selected. Refer to the fold-out page.

8.10.2 Processing an external demand with a 0 to 10 V signal

The controller (= primary controller) can process analog external demands. The 0 to 10 V signal is interpreted as a flow temperature demand of 0.0 to 120.0 °C, i.e. the flow temperature de

mand is 12 °C/V.

The set point of the downstream secondary controller is read at the analog input UI1 and com

pared with the controller's own flow temperature set point. The higher of the flow temperature set points plus 'Set point boost of pre-control loop' is used by the controller to regulate the flow temperature. The 'Set point boost of pre-control loop' parameter improves the control behavior of the downstream heating circuit instruments and compensates for any loss in capacity.

9.1 Sensor failure

Sensor failures are indicated by 'Sensor failure' in the error list. For detailed information, exit the error level and read the different temperature values in the information level: each sensor icon displayed together with '–.–' instead of the measured temperature indicates a defective sensor. The following list explains how the controller responds to the failure of the different sen

sors.

Outdoor sensor: When the outdoor sensor fails, the controller uses a flow temperature set point of 50 °C or 'Max. flow temperature' when the 'Max. flow temperature' is lower than 50 °C.

Flow sensor: When the flow sensor in the heating circuit is defective, the associated valve moves to 30 % travel. DHW heating using such a sensor to measure the charging tempera

ture is suspended.

Flow sensors in the DHW circuit: When the flow sensor fails, the controller behaves as if the flow sensor had not been configured. As soon as the control of the chargingtemperature be

comes impossible, the associated valve is closed.

Return flow sensor: When the return flow sensor fails, the controller continues operation without return flow temperature limitation.

Room sensor: 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; adaptation mode is canceled. The last determined heating characteristic remains unchanged.

Top and bottom storage tank sensors: When one of the two sensors fails, the storage tank is no longer charged.

9.2 Temperature monitoring

When certain measured temperatures deviate from the set points by a defined amount, an error message is generated. The following deviations lead to the 'Temperature monitoring' error mes

sage:

The flow temperature deviates from the set point by at least 10.0 °C for longer than 30 minutes

The room temperature is at least 2.0 °C lower than the set point (flash adaptation active) for longer than 30 minutes

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 electri

cal connections are installed by trained and experienced personnel!

Notes on installing the electrical connections

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.

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 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.

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, should be shielded with separators providing a good ground connection.

Overvoltage protection

If signal lines are installed outside buildings or over large distances, make sure appropriate surge or overvoltage protection measures are taken. Such measures are indispensable for bus lines!

The shield of signal lines installed outside buildings must have current conducting capacity and must be grounded on both sides.

Surge diverters must be installed at the control cabinet inlet.

Connecting the controller

The controller is connected as illustrated in the wiring diagram (pages 96 and 97).

Open the housing to connect the cables. To connect the feeding cables, make holes at the marked locations at the bottom of the rear part of the housing.

12.1 Memory pen

The use of a memory module (order no. 1400-9379) is particularly useful to transfer all data from one TROVIS 5610 Controller to several other TROVIS 5610 Controllers.

The memory module is plugged into the RJ-12 jack at the front of the controller (optional inter

face board (1402-0321) is required). Once the module has been connected, 'READ COPA FROM MEMORY PEN' and 'SAVE COPA TO MEMORY PEN' buttons appear on the screen, provided the memory pen already contains data from a TROVIS 5610 Controller. If the memory pen is empty or contains data from a different controller model, only the 'SAVE COPA TO MEMORY PEN' button appears. After data transfer has been completed, 'OK. Remove pen' ap

pears. If data transfer is not completed successfully, 'Error' appears on the screen.

12.2 TROVIS-VIEW

The TROVIS-VIEW software can be used to configure the controller and change parameter set

tings. It can be connected directly to the controller when the controller is fitted with a suitable interface board or indirectly using a memory pen. The software is based on the modular principle and consists of an operator interface, a communications server and device-specific modules. The operation of TROVIS-VIEW is similar to Windows

Explorer.

The TROVIS-VIEW software can be downloaded from the SAMSON website (Services > Software > TROVIS-VIEW). It is also available on a CD-ROM on request.
