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 Functioning principle The heating circuit with the highest flow set point has priority. This principle applies to all heating 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.
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 temperature to increase. By varying the Gradient and Level parameters, you can adapt the characteristic to your individual requirements.
Functions of the heating circuit The Max. flow temperature and Min. flow temperature parameters mark the upper and lower limits of the flow temperature. tVL [˚C] 100 P1 to 4 Points 1 to 4 tVLmax 90 tVL 80 P1 70 60 P2 50 Outdoor temperature ...min Minimum tVL ...max Maximum tVL 4-point characteristic Reduced 4-point characteristic P3 40 P4 30 Flow temperature tA tVLmin 20 tA 10 20 15 10 5 0 –5 –10 –15 –20 [˚C] Fig.
Functions of the heating circuit Note! The 4-point characteristic function can only be activated when the Adaptation function is not 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.

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 temperature 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).
Functions of the heating circuit 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 decreases.
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: 4 Selection of the operating mode: Automatic mode · Day mode · Night mode 4 Set point correction: during rated operation, the room temperature set point can be increased or reduced by up to 5 °C using a continuously adjustable rotary knob.
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).

Flash adaptation counteracts room temperature deviations by increasing or decreasing the flow temperature by up to 30 °C.
Appendix Parameter WE Parameter level / Range of values Day set point 20 °C PA1, 2, 3 / 10 to 90 °C 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 deactivated.

Appendix 5.14 Releasing the heating circuit The release of the heating circuit in automatic mode is a default setting after the time schedule has been programmed. In addition, it is possible to release the heating circuit over the corresponding potentiometer inputs. When no signal exists at these inputs and the slide switch of the heating circuit is positioned to automatic mode ( ), the heating circuit is in stand-by mode (i.e. just the frost protection is active).

Appendix 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.

Appendix 6.3.2 Set-back operation In all systems with DHW heating and at least one heating circuit with control valve, DHW heating can be given priority by applying set-back operation. The charging temperature can be monitored with the setting Co4 -> Fb06 = OFF and Activate priority in case of deviation > 0.
Appendix Thermal disinfection for preventing legionella infection causes 4 high return flow temperatures during the disinfection cycle (return flow temperature limitation suspended), 4 high storage temperatures after thermal disinfection has been concluded, 4 lime scale (possibly), which can have a negative effect on heat exchanger performance. Note! This function is not available when a storage tank thermostat is used.

System-wide functions 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.
System-wide functions 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, depends 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.
System-wide functions 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 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.

Press the enter key to open the error level. It may be possible to view several error alarms by pressing the enter key. As long as an error alarm is present, the error level appears in the display loop, even though it has not been opened by pressing the enter key.
Operational faults 4 Room sensor RF: Upon failure of the room sensor, the controller functions according to the 4 settings for operation without a room sensor. For example, optimized operation is switched over to reduced operation. Adaptation operation is interrupted. The last determined heating characteristic is not changed anymore. Storage tank sensors SF1 and SF2: Upon failure of one of these sensors, the storage tank is not charged anymore.

Operational faults 8.3 Temperature monitoring The flow temperature and the room temperature can be monitored for any deviations. This function is activated in Co5 -> Fb20. The controller issues an alarm when: the flow temperature deviates from its set point by more than 10 °C for more than 30 minutes the room temperature falls below its set point by 2 °C for more than 30 minutes the return flow temperature limitation is active for more than 30 minutes.
Operational faults 8.4 Monitoring the input terminals for limit violations The controller provides the option to apply limits (in % of measuring range) to two selected inputs (temperature sensor or analog inputs) and to issue an alert to a higher-level control system by writing in the error status register.
Operational faults 8.5 Error status register The HR 60 and HR 61 error status registers (holding register - 16-bit) are used to indicate controller 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.
Operational faults 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: = ([D0] x <1> + [D1] x <2> ) +...+ ([D11] x <2048>) Holding register 61 (A set bit is indicated by Number = Bit no.
Operational faults 8.6.1 Sending text message in case of a fault alarm Currently, text messages can only be sent to the German D1 network. The corresponding access numbers into the D1 network as well as the mobile phone number of the recipient must be set in the PA9 level: 4 D1 access number: 0171 252 10 02 4 (add 0 in front when dialing from a private branch exchange) Digits 0 to 9, P = pause, - = end, max. 22 characters The access number is assigned by Deutsche Telekom and may alter.
Operational faults 4 Station ID: Digits 0 to 9, P = pause, - = end, max.
Communication 9 Communication Using the serial system bus interface, the TROVIS 5179 District 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. 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.
Communication GND TD DTR DCD RD RTS 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 controller is to be connected to the telecommunications network.

Communication Modem timeout (t) 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 Modem dialing pause (P) has elapsed.
Communication 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 different commands, refer to the operating manual of the modem for further details. 9.
Communication 4 Flow temperature (b, °C) 4 Return flow temperature (b, °C) 4 Meter identification number (L without enter key, H with enter key) 4 Meter bus address (sent by WMZ) (A, –) Blinking values in combination with black squares in the top row of the display (fault status of the associated meter –> TV-SK 6311) indicate different faults.
Communication 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.

The following section only applies to devices with LON interface and CO7 -> Fb00 = ON. 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.
Communication 9.6 Requesting/processing an external demand Requesting an external demand The flow temperature set points can be passed on over the LON network in complex heating systems. The external flow set point is compared with the controller’s own flow set point. The higher of the two flow set points is passed on.
Communication Note! In controllers with a firmware version lower than 1.05, the master controller receives the Subnet 1 address and node address 1 and is the decisive controller in LON network terms. It is the only 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.
