Functions of the heating circuit 5 Functions of the heating circuit Which controller functions are available depends on the selected system code number (Anl). 5.1 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).
Functions of the heating circuit Function WE Configuration Outdoor temperature – Current input OFF FB18 = ON 0: 0 to 20 mA = –20 to 50 °C 4: 4 to 20 mA = –20 to 50 °C 5.1.1 Gradient characteristic Basically, the following rule applies: a decrease in the outdoor temperature causes the flow temperature to increase. By varying the Gradient and Level parameters, you can adapt the characteristic to your individual requirements.
Functions of the heating circuit 5.1.2 4-point characteristic 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. The Max. flow temperature and Min. flow temperature parameters mark the upper and lower limits of the flow temperature. P1 to P4 tVL tA ...
Functions of the heating circuit Parameters WE WE* Range of values Min. flow temperature 20 °C 20 °C 20 to 130 °C * 5.2 Default setting applies to system Anl 9, floor heating 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.
Functions of the heating circuit 5.4 Deactivation depending on outdoor temperature 5.4.1 OT deactivation value in rated operation If the outdoor temperature during rated operation 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 a lag time. When the outdoor temperature falls below this value (less 0.5 °C hysteresis), heating operation is restarted immediately.
Functions of the heating circuit Function WE Configuration Summer mode OFF FB3 = ON 01.06 30.09 18 °C Start summer mode / 01.01 to 31.12 Stop summer mode / 01.01 to 31.12 Outdoor temperature limit / 0 to 30 °C 5.5 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, or increases and decreases.
Functions of the heating circuit have been activated. Refer to page 78 onwards for the wiring diagrams of the room panels. Functions WE Configuration Room sensor RF OFF FB13 = ON Potentiometer input 1 to 2 kΩ OFF FB24 = OFF 5.7 Optimization This function requires the use of a room sensor.
Functions of the heating circuit 5.8 Flash adaptation The function is only active in automatic mode ( ). Direct reactions to deviations in room temperature can be achieved using the function block setting: FB2 = ON. A gradient characteristic (FB19 = OFF) must be configured. Flash adaptation counteracts room temperature deviations by increasing or decreasing the level of the heating characteristic by up to 5 °C. The corrections are made after 10 minutes by 1 °C.
Functions of the heating circuit 5.10 Pump management The Pump management function can be used for the heating circuit (circulation pump UP1).
Functions of the DHW circuit 6 Functions of the DHW circuit 6.1 DHW heating in the storage tank system SLP Storage tank charging pump SF1 Storage sensor 1 ZP Circulation pump KW Cold water WW Hot water Fig.
Functions of the DHW circuit DHW heating from the primary circuit (Anl 4): The control valve opens depending on the DHW temperature from its closed position. Stop storage tank charging The controller stops charging the storage tank when the water temperature in the storage tank measured at sensor SF1 reaches the value T = DHW heating ON + Hysteresis.
Functions of the DHW circuit 6.2 DHW heating in the storage tank charging system SF1 Storage tank sensor 1 SF2 Storage tank sensor 2 SLP Storage tank charging pump VF Flow sensor TLP Heat exchanger charging pump ZP Circulation pump KW Cold water WW Hot water Fig.
Functions of the DHW circuit Stop storage tank charging The controller stops charging the storage tank when the water temperature in the storage tank measured at sensor SF1 reaches the value T = DHW heating ON + Hysteresis. In systems with two storage tank sensors, the controller stops charging the storage tank when the water temperature in the storage tank measured at sensor SF2 reaches the value DHW heating OFF.
Functions of the DHW circuit 6.3 DHW heating with solar system (Anl 2, 3, 4, 5 und 9) The systems Anl 2, 3, 4, 5 and 9 include 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 CF is determined. The Solar pump ON parameter determines the minimum temperature difference between sensors SF2 and CF required to activate the solar pump.
Functions of the DHW circuit 6.5 Circulation pump operation during storage tank charging With the setting FB26 = ON, the circulation pump continues operation according to the programmed time schedule even during storage tank charging. With the setting FB26 = OFF, the circulation pump is switched off as soon as the storage tank charging pump is activated. The circulation pump returns to operate according to the time schedule when the storage tank charging pump has been switched off again.
Functions of the DHW circuit Once a parallel pump operation cycle has been activated and the time for Stop parallel operation has elapsed, system deviations greater than 5 °C cause the controller to suspend parallel operation for 10 minutes and to apply priority operation.
Functions of the DHW circuit Set-back difference by set-back of the current flow temperature. The amount of time in which the priority for the DHW circuit is given is set in the Priority in case of deviation parameter. Function WE Configuration Priority for DHW circuit OFF FB8 = ON, Ab 10 min Priority in case of deviation / 2 to 10 min 6.10 Forced charging of the DHW storage tank (Anl 2, 3, 5, 7, 8 and 9) This function is always configured when the system has at least one storage tank sensor.
System-wide functions 7 System-wide functions 7.1 Automatic summer time/winter time changeover The clock is automatically adjusted on the last Sunday in March at 2.00h and on the last Sunday in October at 3.00h. Function WE Configuration Summer time/winter time changeover ON FB5 = ON 7.2 Frost protection When outdoor temperatures below 3 °C occur, the heating circulation pumps UP1 and UP2 are switched on. The controllers regulates the temperature to a flow temperature set point of 20 °C.
System-wide functions The measured temperature reading (return flow temperature) and the set point reading (flow temperature of the heating, charging temperature) blink to indicate that a return flow limitation is active in the control circuit concerned. In systems Anl 2, 3, 7, 8 and 9, the Return flow limitation temperature parameter during DHW heating is used for limitation in the primary circuit while the DHW heating is active.
System-wide functions 7.5 Condensate accumulation control Activate the Limitation of the system deviation for OPEN signal 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.
System-wide functions 7.7 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 temperature 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. Function WE Configuration On/off control for RK1/RK2 ON FB10/FB17 = OFF 5 °C Hysteresis / 1 to 30 °C 7.
System-wide functions Note! The function cannot be selected in systems Anl 4, 5 and 9 with solar system and in system Anl 11 with VF3. 7.10 Flow rate/capacity limitation Flow rate/capacity limitation can be implemented based on a pulse or standardized signal of 0/4 to 20 mA provided by the heat meter. This only applies in plants without solar system. Particularly when a standardized signal is applied, a heat meter (flow meter) with high measuring accuracy is required.
System-wide functions Functions WE Configuration Current input for flow rate measurement OFF FB22 = OFF Flow rate or capacity limitation OFF FB23 = ON Max. limit / 3 to 500 pulse/h Limiting factor / 0.1 to 10 Max. limit for DHW / 3 to 500 pulse/h Limiting factor / 0.1 to 10 500 pulse/h 1.0 500 pulse/h 1.0 7.10.

Display shows: Currently valid system code number, blink Select a function block (e.g. FB20) protected by the key number. Open the function block. 0 0 0 0 0 appears on the display.
Operational faults 8 Operational faults Malfunctions or faults are indicated by the 8.1 icon blinking on the display. Sensor failure The following list explains how the controller responds to the failure of the different sensors. Safety functions such as frost protection and excess temperature protection no longer work when a sensor fails. Outdoor sensor AF: When the outdoor sensor fails, the controller uses a flow temperature set point of 50 °C or the Max. flow temperature (when the Max.
Operational faults 8.3 Temperature monitoring Should a deviation arise in a control circuit that is greater than 10 °C for longer than 30 minutes, the bit D12 is automatically set in the error status register. If this function is not required, configure FB36 = ON, select “steig“ and leave the input BE8 unswitched. 8.4 Error status register The error status register is used to indicate controller or system errors.
Communication Example of a transfer to the control system: The error status register is transferred as a word in a holding register (HR) whose value is calculated as follows: = D_0 + D_1 + … + D_15 = 20 + 21 + … + 215 9 Communication Using the serial system bus interface, the TROVIS 5476 Heating Controller can communicate with a building control system. In combination with a suitable software for process visualization and communication, a complete control system can be implemented.
Communication 9.1 Controller with RS-232-C port 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 controller is to be connected to the telecommunications network.
Communication Functions WE Configuration Modem operation OFF FB44 = ON 8 bit 30 min 5 min 5 min PULS – 8 bit/16 bit Cyclical initialization In* / 0 to 255 min Dialing pause to GLT PA* / 0 to 255 min Modem timeout t0* / 0 to 99 min Dial procedure / PULS/ton Phone no.
Communication 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.
Communication Modem time-out (t0) When the controller connects to the GLT but without addressing a Modbus data point, the connection is closed after the time specified for Modem time-out has elapsed. If the error status register has not been read during the GLT connection, the controller dials up to the GLT again after the Dialing pause to the control station (PA) has elapsed.
Communication Note! A 15 V DC supply voltage (+15 V at terminal 15 connected to the meter bus connection terminal 3) can be used at the WMZ connection of TROVIS 5476 Controller when the red jumper on the back of the controller is located pointing towards the edge of the controller (Fig. 8). Otherwise, the meter bus module in the heat meter is supplied.
Installation for details on which listed heat meters fulfill this criterion and can be used for limitation purposes. In case of battery-operated 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 technical documentation TV-SK 6311 provides more details on these matters. 4 A system with simultaneous room heating and DHW heating requires maximum energy.
