Start-up Start-up Setting the system code number and the boiler rating 7 different hydraulic schematics are available. Each system configuration is represented by a system code number (Anl). The different schematics are dealt with in section 4. Available con- troller functions are described in sections 5 to 8. Changing the system code number resets previously adjusted function blocks to their default set- tings (WE).
Start-up Set the required rating. Set first the capacity of the basic stage and then the total capacity of the burner of two-stage and modulating burners. Confirm the rating. Set the capacity of the second burner in systems Anl 4 to 7. Select End on the display.

Start-up If the temperature values displayed at the controller differ from the actual temperatures, the measured values of all connected sensors can be changed or readjusted. To calibrate a sensor, the currently displayed sensor value must be changed such that it matches the temperature (ref- erence temperature) measured directly at the point of measurement.
Start-up Select function block Fb23. Activate editing mode for function block Fb23. Deactivate function block Fb23. Confirm setting. Select End on the display. Exit the configuration level. Return to the operating level. Note! The adjusted sensor values are not reset by the function for resetting to default values. Resetting to default values All parameters and function blocks that can be set without entering the key number can be reset to their default settings (WE).

Functions of the heating circuit Functions of the heating circuit Outdoor temperature-dependent advance heating Only selectable for systems Anl 1 to 3 with Co5 -> Fb13 = ON. The controller switches the heating on before the time-of-use starts in normal operation depend- ing on the outdoor temperature.
Page 43
Functions of the heating circuit Outside the times-of-use, the controller monitors the Night set point (reduced room temperature) or the Sustained temperature in the case of room temperature-dependent deactivation. When the temperature falls below the night set point, the controller heats with the max. flow tempera- ture until the measured room temperature exceeds the adjusted value by 1 °C.
Functions of the DHW circuit Functions of the DHW circuit Only systems Anl 1 to 3 have their own DHW heating (DHW heating in storage system with Co5 -> Fb13 = ON). The systems Anl 4 to 7 do not have their own DHW heating; they are, however, able to process an external DHW demand (->...
Functions of the DHW circuit Operation with two storage tank sensors SF1 and SF2 The controller begins charging the storage tank when the water temperature measured at sen- sor SF1 falls below the set point DHW demand ON . The controller stops charging the storage tank when the water temperature in the storage tank measured at sensor SF2 reaches the value DHW demand OFF .
Functions of the DHW circuit Functions Configuration Heating circuit with DHW heating Co5 -> Fb13 = ON DHW priority over HK2 Co4 -> Fb06 = ON Heating circuit 3: During the storage tank charging, the direct heating circuit is switched off. The separate heating circuit runs in parallel.
Functions of the DHW circuit Thermal disinfection (Anl 1 to 3) In all systems with DHW heating, the DHW storage tank is thermally disinfected on the selected Day of week or daily. The storage tank is heated up to the adjusted Disinfection temperature . The charging temperature is always 5 °C higher than the Disinfection temperature .
Functions of the DHW circuit External DHW demand (Anl 1 to 7) This function allows the boiler controller to switch over to the Boiler set point for DHW demand when the binary input BE4 (WWA) is closed. The thermal disinfection has priority when the ex- ternal DHW demand and thermal disinfection coincide.
System-wide functions System-wide functions Weather-compensated control When weather-compensated control is used, the flow temperature is controlled according to the outdoor temperature. The boiler characteristic in the controller defines the flow temperature set point as a function of the outdoor temperature (–> Fig. 5). The outdoor temperature required for weather-compensated control is measured at the outdoor sensor at the input AF or received over a 0 to 10 V signal at the input AE2.
System-wide functions 8.1.1 Gradient characteristic Basically, the following rule applies: a decrease in the outdoor temperature causes the flow tem- perature to increase. By varying the 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.
System-wide functions 8.1.2 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 and the Flow temperature . The Boiler set-back difference is predetermined for points P1 and P2 and for points P3 and P4 in the corre- sponding parameter level, resulting in the dashed line in Fig.

System-wide functions Differential temperature control using variable weighting factors This function allows the return flow temperature, total (RüFg) to be taken into account in the con- trol loop, in addition to the flow temperature, total (VFg). The difference between the flow temperature, total (VFg) and return flow temperature, total (RüFg) is specified using the Intended temperature difference parameter.
System-wide functions 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 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 on the next day, summer mode is deactivated on the following day.
System-wide functions 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. Configuration Function Summer time/winter time changeover Co5 -> Fb05 = ON Frost protection To protect the system from freezing up, the flow temperature or return flow temperature are monitored.
System-wide functions Forced operation of the pumps When the pumps (Pu1, Pu2 and Pu3) have not been activated for 24 hours, forced operation of the pumps is started between 12.00h and 12.01h. The forced operation of the storage tank pump SLP is operated between 12.01h and 12.02h. 8.10 Flow temperature limitation The boiler temperature is regulated to the limit set in Maximum flow temperature and an alarm is displayed when the flow temperature at the boiler outlet of a modulating burner reaches the...
System-wide functions 8.11 Control mode The selected control mode (section 8.11.1 to 8.11.3) of the return flow boost affects the control mode of the modulation and vice versa. The following connection applies: Return flow boost in continuous control <–> Modulation in three-point Return flow boost in on/off or three-point control <–>...
System-wide functions * Only in systems Anl 4 to 7 Note! The control mode is configured separately in Co2 -> Fb14 or Fb15 for the separate heating cir- cuit in systems Anl 1 to 3 (Co5 -> Fb13 = ON). 8.11.1 Three-step control The set point can be controlled using a PI algorithm.
System-wide functions 8.12 Control signal deactivation This function protects three-point stepping actuators without final position deactivation from over- loading by monitoring the total of the control signal pulses. No further control signals are issued if it exceeds three times the Valve transit time T .
System-wide functions System Anl 7: The outdoor temperature cannot be passed on as the output AA2 is constantly used for a control signal or for the modulation control. 8.15 Locking of changed settings An active locking of all manual levels means that no settings (configuration and parameterization) can be performed at the controller.

Communication Communication Using the serial system bus interface RS-232-C, the TROVIS 5474 Boiler 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.
Communication 10.1 Controller with RS-232 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 control- ler is to be connected to the telecommunications network.
