carefully and pay attention to the safety instructions given in particular. Please consult this manual if anything is unclear. Make sure that you understand the instructions contained in this manual and that you are sufficiently informed regarding the way in which the biomass boiler system works. Should you have any queries at any time, please do not hesitate to contact HERZ. For safety reasons, the owner of the system must not make any changes to the construction or the state of the system without consulting the manufacturer or his authorised representative. Make sure that there is a sufficient supply of fresh air to the boiler room (please heed the relevant national regulations) All connections are to be checked before the commissioning of the system in order to make sure that they are leak-tight. A portable fire-extinguisher of the prescribed size is to be kept by the boiler room. (Please heed the relevant national regulations). When opening the door to the combustion chamber, make sure that no flue gas or sparks escape. Never leave the combustion chamber door open unattended as toxic gases may escape. Never heat the boiler using liquid fuels such as petrol or similar. Carry out maintenance regularly (in accordance with the maintenance schedule) or use our Customer Service department. (The minimum maintenance intervals specified in the TGPF are to be observed). When carrying out maintenance on the system or opening the control unit, the power supply is to be disconnected and the generally valid safety regulations are to be heeded. In the boiler room, no fuels may be stored outside the system. It is also not permitted for objects which are not required for the purpose of operating or carrying out maintenance on the system to be kept in the boiler room. When filling the fuel bunker using a pump truck, the boiler must always be switched off (this is stamped on the cover of the filling connection). If this instruction is not heeded, flammable and toxic gases may get into the storage room! The fuel storage room is to be protected against unauthorised access. Always disconnect the power supply if you need to enter the fuel storage room. Always use low-voltage lamps in the fuel storage room (these must be approved for this type of use by the relevant manufacturer). The system is only to be operated using the types of fuel prescribed. Before the ash is transported further, it must be stored temporarily for at least 96 hours in order to let it cool down. Should you have any queries, please call us on +43 / 3357 / 42840-840. Initial commissioning must be carried out by the HERZ Customer Service department or an authorised specialist (otherwise any warranty claim will not be applicable). Ventilate the pellet storage room for ~ 30 minutes before going in. The boiler meets the requirements of the Association of Swiss Canton Fire Insurance Companies or national fire safety regulations. The customer himself shall be responsible without exception for ensuring that these regulations are complied with on site! 4 Safety notes 1.1 In order for the system to be operated and maintained safely, it must be operated and maintained properly by qualified personnel while heeding the warnings in this documentation and the instructions on the systems. Basic safety information Due to its functionally limited electrical and mechanical characteristics with regard to usage, operation and maintenance, if the equipment is not able to work according to its appropriate use or improper interference occurs, it may cause serious health and material damage. It is therefore conditional that the planning and implementation of all installations, transportation, operation and maintenance will be carried out and supervised by responsible, qualified persons. When operating electrical systems, certain parts of those systems will always carry a hazardous electrical voltage or be exposed to a mechanical load. Only appropriately qualified personnel may carry out work on the system. They must be thoroughly familiar with the content of this and all other manuals. In order for this system to function safely and without any problems, transportation, storage, operation and maintenance must be carried out properly and carefully. Instructions and information on the systems must also be heeded. 1.2 Installation General notes In order to ensure that the system will function properly, the relevant standards and the manufacturer’s installation instructions are to be heeded during the installation of the system! Documents from the manufacturer relating to the heating devices and components used are available from HERZ on request. 1.3 Operation and maintenance 1.3.1 General notes Don´t open the boiler doors until “HEATING OFF” is displayed, otherwise a risk of deflagration (explosion) is given. 1 In unfavourable operating conditions, the temperatures of parts of the housing may exceed 80 °C. If the door to the ash container is opened during operation, the fuel supply will be shut off and the boiler will switch to the burnout phase. Afterwards the boiler will switch to the operating mode “HEATING OFF”. Ambient conditions Operating temperature: Warehouse-/ transport temperature: Humidity: operation storage 1.3.2 +10 to +40 °C -20 to +70 °C 5 to 85 % 5 to 95 % Operation Covers which prevent contact with hot or rotating parts or which are required in order to direct the flow of air correctly and thus ensure the effective functioning of the system must not be opened during operation. In the event of a fault or unusual operating conditions such as the emission of smoke or flames, the system is to be switched off immediately by operating the emergency stop button. Notify the HERZ Customer Service department immediately. If the boiler room door main switch is operated or if a power failure occurs, the system will be taken out of operation immediately. The remaining quantity of residual fuel will burn independently without giving off any toxic gases, if the chimney draught is sufficiently. Therefore the chimney must be designed and produced in accordance with DIN 4705 or EN 13384. When the boiler is switched on again, the system has to be checked in order to make sure that it is fully functional and a safe operation of the whole system must be guaranteed! 5 2 Warning notes The generated system noise during operation does not present any danger to the operator´s health. If the residual flue gas oxygen content drops below the required minimum of 5 %, the fuel supply will be stopped automatically and will not be activated again until the residual oxygen content has risen to more than 5 % (fault text: MIN O2 [%] 5.0, see chapter 1.1.1) 1.3.3 recommended to be carried out regularly by authorised personnel or by the HERZ Customer Service department. Spare parts must be obtained directly from the manufacturer or a distribution partner. The customer will not be exposed to any health risks as a result of the noise generated by the machine. 2 WARNING NOTES Risk of injury and damage to property due to improper handling of the system. Maintenance Before starting to carry out any work on the system, but especially before opening covers protecting live parts, the system is to be properly disconnected from the power supply. Besides the main circuits, attention is also to be paid to any existing additional or auxiliary circuits in the process. The normal safety rules according to ÖNORM are: Caution – hot surface Disconnect all poles and all sides! Warning – against hand injuries. Ensure that the system cannot be switched on again! Check to ensure that no voltage is No admittance without authorisation. connected! Earth and short-circuit! Cover adjacent live parts and locate hazardous areas These above-mentioned measures must not be reversed until the system has been fully installed and maintenance has been completed. Personal dust masks and gloves must be worn when carrying out maintenance in the combustion chamber or the ash collector or on flue gas-carrying parts and when emptying the ash container, etc.! Extra-low-voltage lamps are to be used when carrying out maintenance in the fuel storage room. Electrical equipment in the fuel storage room must be designed in accordance with ÖN M 7137! In order to prevent any maintenance errors, if maintenance is not carried out properly, it is 6 However, adherence to guidelines for transportation, installation, operation and maintenance notices as well as technical data (in the operating instructions, product documentation and on the equipment itself) which are not specifically highlighted, is also vital to avoid breakdowns which may directly or indirectly cause major personal or material damage. General note For reasons of clarity and possible permutations, this documentation does not contain all detailed information and cannot take account of every conceivable operating or maintenance scenario. Should you require further information or encounter specific problems, which are not handled in detail in the documentation supplied, you can obtain the required information from your specialist dealer or direct from HERZ. People (including children) who, because of their physical, sensory or mental capabilities or because of their lack of experience or knowledge, are unable to use the equipment safely must not use this equipment unless they are supervised or instructed by a responsible person. Fuels 3 FUELS The HERZ firematic boiler should be operated with the fuels and their properties which are described in this chapter. 3.1 Calorific value at as-delivered condition > 4.6 kWh/kg Bulk density (BD) at as-delivered condition > 600 kg/m³ Mechanical Strength (DU), EN 15210-1 at asdelivered condition in m-%: DU 97.5 ≥ 97.5 Diameter 6 mm Wood chips Wood chips for non-industrial use with low fines content according to EN 14961-1/4 with following specification: 3 Property class A1, A2, B1 G30 respectively G50 ÖNORM M 7133 4 according to The nominal power and the emission values can be guaranteed up to a maximum water content of 25 % and a minimum calorific value of 3.5 kWh/kg of the permissible fuel. Particle size P16B, P31,5 and P45A Water content min. 15 % up to max. 40 % Ash content in m-%: <1.0 (A1), <1.5 (A2), <3.0 (B1) Calorific value in as-delivered condition > 3.1 kWh/kg Prevent the entering of debris such as stones or metal particles into the system! Sand and soil lead to higher level of ash and slagging precipitation. Bulk density (BD) in as-delivered condition > 150 kg/m³ There may be a formation of slag according to the fuel quality, which has to be removed by hand. The property classes A1 and A2 represent fresh wood and chemically untreated wood residues. A1 contains fuels with low ash content, which indicates little or no bark and fuels with lower water content, while class A2 has a slightly higher ash content and/or water content. B1 extends origin and source of class A and includes additional materials, such as short rotation plantation wood, wood from gardens and plantations etc., as well as chemically untreated industrial wood waste. Class B2 also includes chemically treated industrial wood waste and used wood. In the case of non-compliance, any warranty or guarantee will be rendered null and void. The burning of unsuitable fuels could lead to uncontrolled combustion. Operational faults and consequential damage are likely to occur. 3.2 From a water content of about 25 % and a calorific value < 3.5 kWh/kg a reduced output is expected. If a different fuel is named explicitly on the order respectively the order confirmation, the system can be operated with the mentioned fuel. Note: The system is set to the agreed fuel at the commissioning. This setting (ID-fan speed, fuel, flow and backflow, cycle times, etc.) should not be changed when using constant fuel quality. Wood pellets Wood pellets for non-industrial use according to ENplus, Swisspellet, DINplus or ÖNORM M 7135 resp. pellets according to EN 14961-2 with following specifications: Property class A1, A2 The maximum permissible fines content in the fuel storage room must not exceed 8 % of the fuel volume (determined using a perforated screen with holes 5 mm in diameter)! Fines content at loading: < 1.0 m-% 4 5 5 Only if using an agitator with 3x400 Volts Property class A2 only at firematic 80 – 301 7 4 4 Safety devices SAFETY DEVICES The safety devices must be dimensioned and installed according to ÖN B 8133. The safety valve in the boiler circulation serves as a final safety device against malfunctions of the equipment. All legal safety regulations must be adhered to on-site via the authorised specialist company. Earthing or potential equalisation must be carried out on the whole heating system according to EN 60204-1 by an authorised specialist company. 1 Safety temperature limiter 4 Burn-back safety unit Should the boiler temperature exceed 95 °C, the equipment must be switched off for safety reasons. The safety temperature limiter (STL) locks in this event. The burn-back safety unit prevents a burn-back into the fuel storage room. The unit separates the burning chamber and the fuel storage room. The burn-back safety unit is conducted like a fire flap and opens only when fuel is fed to the boiler. Possible causes may be: Performance decrease in the boiler was interrupted abruptly. This can occur due to the switching off a pump or sudden shutting of the heating circuit mixer. The load pumps are being controlled by the HERZ Control. The so-called excess temperature flue gas would be automatically activated by the HERZ Control. This avoids higher boiler temperatures. The boiler is too large. The fuel level is set too high. Loss of power supply Etc. At First the cause of the failure must be found and be corrected, afterwards the safety temperature limiter can be unlocked. The boiler temperature must be lower than 75 °C before unlocking. Only after the temperature fell below 75 °C the malfunction can be rectified. To acknowledge the malfunction unscrew the STL covering and put gentle pressure, using a sharp object, to the STL. 2 and 3 automated extinguishing device The Boiler features an automated extinguishing device. The device consists of a thermal safety valve, a thermostat valve (3) and a water tank (2). If the feeding screw temperature gets exceeded, the valve opens independently and flushes the feeding pipe. This extinguishing device is used as a safety device at burn back. 8 5 Safety valve The safety valve automatically releases, when the pressure or temperature exceeds preset limits. The safety valve has to release at the maximum allowable pressure (according to boiler plate). 6 Safety heat exchanger The safety heat exchanger is a built in safety device and has to be connected to a thermal release valve and installed, according to applied standards. The safety heat exchanger has to be connected directly to a cold water pipe (pressure ≤ 3 bar) 7 Ash container and burning chamber safety device The ash containers are connected contact-free (inductive sensor) to the boiler. Fuel storage room temperature monitoring The fuel storage room temperature monitoring is placed directly above the transport screw. If the storage room temperature exceeds its preset limit, the boiler will switch to the operate condition „HEATING OFF“ and displays a fault report. Additionally a fault sensor output gets active. Conduct alerting in accordance with national standards.

The filling of the fuel storage room is carried out with vertical filling screws (1). Please consider that the installed room discharge and storage room filling system can be different to the displayed system. If all room discharge and storage room filling systems of HERZ would be presented, the scope of this guide would be exceeded considerably. More information can be provided by the company HERZ. 1 2 3 figure 5.1: System overview In the following chapter the boiler (2) and the room discharge system (3) and its individual components are described and displayed. 10 System 5.2 5 Boiler firematic 20 – 60 firematic 80 – 499 7 7 2 2 11 11 8 8 1 1 6 6 3 10 9 4 5 figure 5.2: firematic 20-60 components 1 2 3 4 5 6 7 3 9 10 4 5 figure 5.3: firematic 80-499 components Burn back protection device The burn back protection prevents burn back in the fuel storage room. It separates additionally the combustion chamber and the fuel storage room. Integrated control The system is controlled and operated centrally via a user-friendly touch display on the firematic boiler. Automatic ignition using hot air fans firematic 20 – 60: Tipping grate provides grate cleaning firematic 80 – 499: Combined step-/moving grate and tipping grate 2-zone combustion chamber Standing pipe heat exchanger with integrated turbulators and cleaning mechanism The heat exchanger surface gets cleaned automatically via the integrated turbulators, even during heating operation, no manual cleaning necessary. Automatic flue gas and combustion monitoring via lambda probe control A built in lambda probe, which monitors continuously the flue gas content values, detects fuel quality changes and ensures optimum combustion and low emission values. The lambda probe controls the primary and secondary air supply and ensures a complete combustion, even during minimum load. 8 9 10 11 Speed-controlled ID-fan The ID-fan on the backside of the boiler generates low pressure within the boiler. The secondary- and primary air get sucked out due low pressure. Combustion and fly ash discharge Via two ash discharge screws the combustion and fly ash get automatically fed into the ash container(s). Ash container(s) The removable ash container(s) with wheels enables simple and convenient emptying of the ash. Safety temperature limiter STL The STL is a safety device and locks the boiler if the boiler temperature exceeds 95 °C (see chapter 4). 11 5 5.3 System Room discharge system 1 2 3 4 5 6 figure 5.4: Modular agitator system 1 Stirring disc 2 Drive 3 Gear mounting 4 Feed screw 5 Open screw channel (in the fuel storage room) 6 Closed screw channel (outside the fuel storage room) 7 Overflow protection (end switch) 8 Release shaft 9 Drive motor 12 7 8 9 Mode of operation 6 MODE OF OPERATION 6.1 Feeding system The fuel is fed from the fuel storage room by the room discharge system to the burn back protection device. Fuel passes the hopper first, afterwards the back burn flap. The back burn flap gets steered by a spring loaded servo motor. If the servo motor operates current less, the back burn flap will close independently. Next the fuel is fed towards the burning chamber by the feeding screw. The achieved fuel level is a crucial factor of the boiler heat output and operating mode. 6.2 Feeding type The operation of the firematic is based on a pulse-no-pulse ratio, which controls the feeding system. The feeding values are set up via the menu “Fuel values” (only available in the service area) and modulated by the combustion control system. 6.3 Combustion air control The supplied combustion air is differentiated between primary and secondary air. The primary air is initiated directly into the embers. The secondary air gets used to actuate the developed flame to a completely. The air supply is piped via vents on the burner side (underneath side cover). The ID-fan on the backside of the boiler generates low pressure within the boiler. The secondaryand primary air get sucked out due low pressure. The ID-fan speed is controlled according to the boiler temperature and the lambda probe control. 6.4 Boiler operation The boiler starts up automatically with its built-in automatic ignition, when heat is required. The heat requirement can be controlled by the weather or by a remote sensor (optional), depending on any heating circuit. A room thermometer can also be used to generate an external requirement. The boiler can also be started up by the requirement of a hot water tank. The boiler output can be controlled by set up values and adjusted to local conditions. The boiler control prevents too low boiler temperatures to avoid effect on the durability of the system. Too high boiler temperatures are not permissible. Expansion cracks at insulating plates, respectively burning chamber stones, don´t affect their capacities and don´t represent warranty claim. 6.5 6 Commissioning The commissioning must be carried out by HERZ factory customer service or an authorised specialist. A pressure measurement is conducted additionally after boiler has been operated with the actual fuel for > 1 hour and a flow temperature of 70-85 °C. The result of the pressure measurement represents a characterisation of the draught during normal operation and shows, if the required draught has been reached. If a deviation occurs, the existing chimney has not been dimensioned correctly or dimensioning underlying installations have not been carried out correctly (e.g.: faulty connections, false air inflow, too long connection pipe,...) and the boiler does not operate properly. During initial operation and commissioning the system controls and safety devices must be checked and the handling of the boiler as well as the system maintenance schedule must be explained to the operator. The hydraulic balancing of the equipment (pipe installation) must be carried out by an authorised specialist company (installer). The installer’s duty according to ÖNORM 12170 is to create documentation of the heating system. The documentation has to be retained in the boiler room. 6.6 Operating and impermissible temperatures Boiler temperature The HERZ firematic boiler operates at a boiler temperature between 65 to 90 °C. If the return flow temperature is lower than 55 °C, flue gas will condense on the inside of the boiler. So if the boiler starts up, the operating temperature (from 65 to 90 °C) must be reached as quickly as possible in order to avoid condensation. The back flow temperature may also be lower than the permissible value at correct boiler operating temperature. This condition should be avoided by a back flow temperature increase. Note! All guarantee or warranty claims are invalidated in the event of damage by corrosion arising due to impermissible operation temperatures. 13 7 Operating conditions Back flow temperature 7 The back flow temperature must exceed 55 °C (60 °C) as quickly as possible, depending on the boiler type. Temperature level retention of the back flow or the boiler temperature is achieved using a so-called back flow bypass or back flow temperature monitoring. In this case the flow is admixed via a pump and a valve to the back flow. Heating off The boiler´s heat energy can only be used after the back flow temperature has exceeded 60 °C. Too high boiler temperatures The HERZ firematic boiler can be operated with a maximum boiler temperature up to 90 °C. If the decrease of performance drops suddenly (mixers shut-off, hot water tank load pump switches off) the boiler´s saved heat energy can overheat the boiler. The firematic boiler has three different preinstalled safety devices to prohibit a further temperature increase: Overheat temperature (higher than 92 °C boiler temperature) At this temperature the connected consumer pumps get switched on in order to conduct overheat (consumer pump connection to the HERZ controls is required). If the consumer pumps aren´t connected to the HERZ controls, a higher probability of overheating, resulting in failure, is given. Thermal release valve The thermal release valve must be connected to the built in safety heat exchanger, according to applied standards. Safety temperature limiter – STL If the boiler temperature exceeds 95 °C, a fault report gets indicated, the boiler gets switched off and the safety temperature limiter locks itself. Flue gas temperature The flue gas temperature depends on the boiler operation conditions, the fuel, the ventilator setting and the boiler type. OPERATING CONDITIONS During this phase the boiler is switched off, i.e. the burner is blocked. Ready The boiler- respectively the buffer temperature is sufficiently high to provide the required heat load, or the boiler temperature has reached the switch off temperature. Ignition preparation During this phase the grate gets cleaned and the lambda probe gets pre-heated. Pre-aeration During the pre-aeration phase the burning chamber and the chimney get purged with fresh air. Cold start If the boiler room temperature is lower than the identified boiler room ignition temperature (150 °C), the boiler performs a cold start and fuel is fed to the burning chamber. At the same time the fuel gets ignited by the ignition fan. An ignition monitoring is conducted during this phase. After successful ignition, the boiler switches to the burning phase and the ignition fan stopping time (1 minute) starts to cool down the ignition fan heating element. If ignition wasn´t possible prior the maximum ignition period (3x set up time), the boiler will switch off and the fault “IGNITION” (see fault 66) will appear in the fault list. Scorch phase During the scorch phase the boiler control tries to achieve an even fire bed. The length of the scorch phase can be set in the fuel value settings (only available in the service area). Pay attention to a higher oxygen content at the combustion to achieve an even fire bed faster. Observe: The chimney must be insensitive to moisture and calculated and dimensioned according to DIN 4705 or EN 13384. HERZ does not carry out chimney calculations. The chimney calculation must be calculated by authorised personnel. A miscalculated or undimensioned chimney may lead to a malfunction of the system. 14 Start up phase During the start up phase the boiler operates at nominal heat output. If the boiler set temperature is reached, the boiler will switch to the regulation phase. Operating conditions 7 Regulation phase Freezing protection During the regulation phase the boiler is modulated between nominal load and partial load. If boiler oversupplies heat, i.e. if the boiler target temperature + control hysteresis gets exceeded, the boiler will switch to the operating condition „ready”. If the freezing protection operates, the back flow bypass pump will switch on only if the boiler is in operating mode “HEATING OFF” or “BURNER STOP”. Otherwise (freezing protection disabled) the boiler will start up and heat up to minimum boiler temperature 65 °C. Burn out phase Lambda control If the boiler will be switched off the remaining quantity of residual fuel will burn independently. Pay attention to the burn out phase time setup, if chosen too short, fuel will not be burned accordingly. The amount of material and the rotation speed of the ID-fan are controlled by the lambda control. The control is able to detect marginal deviations of the fuel quality and induces a combustion improvement. Burner cleaning During the burner cleaning phase ash gets removed off the grate. The boiler switches to the burn out phase and remaining fuel gets burned out. Afterwards the grate gets cleaned and the boiler switches to normal operation. The burner cleaning interval is calculated by the feeding screw operating time. The cleaning interval is set up with the parameter “cleaning interval” in the service area. Heat exchanger cleaning The Heat exchanger gets cleaned automatically. The cleaning interval and duration is set up in the service area with the parameter “heat exchanger cleaning interval“ respectively „heat exchanger cleaning duration“. Boiler output control The boiler output gets modulated by the boiler set temperature + control hysteresis (= regulation end). If the regulation end is reached, the boiler will switch to the burn out phase. Flue gas temperature control If the maximum flue gas temperature is exceeded, the boiler output will be reduced. If the actual flue gas temperature is lower than the maximum flue gas temperature, the boiler will switch to normal output control. Flame monitoring temperature) (burning chamber If the burning chamber temperature fluctuates greatly during operation, the boiler will switch off. 15 8 Temperature manager 8 TEMPERATURE MANAGER The heat demand of the individual modules (boiler, hot water tank, heating circuit, solar, etc.) is controlled by the temperature manager. The below-mentioned scheme (see figure 8.1) explains the functionality of the temperature manager. A module contains of an in- and output. Every module sends a required demand temperature to the temperature manager. The sent required demand temperature is a sum of an internal calculated temperature demand + set up increase. The heat supplier (= heat generator respectively boiler/hot water tank), which receives the different module demand temperatures from the temperature manager, must supply the required temperature demand to the different modules. The temperature manager calculates the maximum demand temperature of all modules. Example: Heat supplier = boiler Module 1 & 2 = heating circuit 1 & 2 Module 3 = hot water tank Module 4 = buffer calculated required temperature [°C] Temperature increase [°C] Required temperature of the modules [°C] Heating circuit 1 60 5 Heating circuit 2 30 3 Hot water tank 55 2 Buffer 75 2 65 33 57 77 Maximum temperature requirement 77 BOILER (Heat supplier) TEMPERATURE MANAGER BUFFER (Module 4) Temp. requirement + increase HEATING CIRCUIT 1 (Module 1) HEATING CIRCUIT 2 (Module 2) HOT WATER TANK (Module 3) Temp. requirement + increase Temp. requirement + increase Temp. requirement + increase figure 8.1: Temperature manager (simplified schema – example) 16 T-CONTROL 9 9 T-CONTROL The handling and menu navigation are described in this chapter. Every single T-CONTROL parameter is explained in chapter 9.11 (page 27). figure 9.1: T-CONTROL 9.1 Starting the system To switch on the display, two conditions must be fulfilled: The boiler must be connected to the power supply The main switch (1) on the boiler front must be switched on (only by firematic 80 – 499, see figure 9.1) If these two conditions are fulfilled, the starting process of the display, which takes 1-2 minutes, starts. 1 figure 9.1: Boiler main switch (only firematic 80 – 499) 17 9 9.2 T-CONTROL Operation and handling The touch panel is a touch-sensitive screen and control unit. By touching the screen you can change released values or move to other pages. The screen navigation and input can be done with finger, pen, pencil, etc. 9.3 Main menu After start up figure 9.2 will appear. In the centre of the screen important values according the boiler, buffer, hot water tank, heating circuit and so on are shown. The shown values can be adapted individually (see chapter 9.8). figure 9.2: Main menu If the following symbol is pressed: the main menu will be displayed (see figure 9.2) fault messages (warnings & alarms) will be displayed (see chapter 9.9) the individual modules (boiler, hot water tank, buffer, heating circuit, solar, hydraulic compensator, net pump, zone valve, external demand) will be displayed.

(see chapter 9.6) In general the field is used to display the operating conditions (see chapter 7) more important values will be shown on the second page 18 T-CONTROL 9.4 9 Symbols explanation In this section important symbols are explained. The CHIMNEY SWEEPING FUNCTION provides a test mode for the chimney sweeper. The boiler is operated steadily at nominal output and all consumer values are set to its maximum during the chimney sweeper carries out its measurements. The measurements must be carried out after “chimney sweeping mode” appears on the display and a developed flame exists. If the maximum boiler temperature or the permissible chimney sweeping time is exceeded, the chimney sweeping function will abort. The chimney sweeping time is 25 minutes by default, the remaining time counts after boiler status “chimney sweeping mode” starts. With the aggregate-test connected components can be tested individually. The symbol is only visible, if: the code has been entered (see chapter 9.5, page 20) and the boiler is in the “heating off” operation mode (only at the boiler aggregate-test!) If the Aggregate-Test is active, the symbol will turn green and the message “AGG-Test ACTIVE” is shown on the display. Information such as firmware-module, hardware-module, software version etc., of each module (boiler, hot water tank, buffer, solar, heating circuit). These symbols (navigation) can be used to navigate in each module (boiler, hot water tank, buffer, solar, heating circuit, hydr. compensator, net pump, zone valve, ext. demand). An alternative to the illustrated navigation method is the wiping to the right or left. Back to the modules overview (boiler, hot water tank, buffer, solar, heating circuit, hydr. compensator, net pump, zone valve, ext. demand). 19 9 T-CONTROL Code – entry 9.5 If entering the code, the following operations can be performed: Setting up values Activation of the aggregate-test (see chapter 9.4) Setting up or changing of date & time (see chapter 9.7) Navigation in the menu settings (see chapter 9.13) Navigation 1: Navigation 2: Screen: Screen: figure 9.3: Code - entry figure 9.4: Code - entry If the following button is: figure 9.4 is displayed.
