Initial start-up. 1. Configuration The controller is adapted to pre-burner operating at full power rating. In case of mounted the burner in the boiler of a lower power installer, with the available parameters, should set the appropriate power rating of the boiler - otherwise user will be exposed to unnecessary loss of fuel For proper burner start is required starting dose of fuel approx g. Responsible for this parameter is a starting dose of fuel installation (measured in seconds). Instalator should check that feeder, working for the time specified by this parameter, provides appropriate amount of pellets 7

8 and, if necessary. correct parameter setting Attention! Too much fuel in the burner during ignition may result in unnecessary prolongation of heater operation in extreme cases, also reporting a bug firing. 2. Set-up of the language. Language in which the controller communicates with the user is going by selecting the buttons: SETTINGS -> GENERAL -> LANGUAGE. IV. Startup and shutdown of the boiler. 1. Enabling the burner - firing up the boiler. The message "Burner off" on the main screen and the presence of a button indicates automatic shutdown of the burner. To properly make the boiler firing up: Press the button - then go to the manual filling of fuel. Before starting feeder storage tank should be completely filled with pellets. Press the On and Off manually run the feeder storage tank until the first pellet feeder discharge. Press the button to turn on the burner and the transition to a state of Readiness. After turning on the burner main screen appears. The controller switches to automatic mode. If the current boiler temperature is below the set point at least 5 degrees followed Firing-Up. Otherwise, the controller expects the Readiness state for the right conditions to start. 2.

Press to switch the screen Boiler Info.. VI. Operation algorithm. If the engine is switched off the controller controls only the pumps and heating circuits controlled by valve control modules. Any burner`s work 12

13 or its components is prohibited. 1. Burner`s work. Immediately after turning on the burner goes into READINESS state and is waiting for the proper temperature to start. Conditions of ignite / extinguish of the burner are based on the current temperature of the boiler and the hysteresis of work (as determined by the installer). If the water temperature exceeds a predetermined operating temperature hysteresis value of work (typically 5 C) the burner unconditionally, regardless of the method of adjustment, go to the READINESS state, and died previously contained in the fuel. Rekindle will be possible only when the water temperature falls below the operating temperature of the hysteresis work. Measuring the presence of the flame is implemented by a photoelement placed in the burner. It is recommended the periodic cleaning. FIRING-UP always starts pre-cleaning the burner by turning on blower to maximum Power. Then, the charge starting dose of fuel is following and warming heater of igniter. After warming up of The heater, blower starts at low power. After a relatively short time, the fuel ignites in the burner - heater is switched off. After switching off the heater, fuel is replenished in very small portions. Amount of fuel and Power of blowers are gradually increased until the optimal warm-up the burner. After completion of ignition controller enters WARMING-UP, next WARMING, starting the power control in accordance with the parameters set by installer. The maximum power of the boiler may be limited by the user by POWER BOILER parameter that is available in the combustion settings. If the installer set step adjustment of the burner, the controller controls the burner working at nominal capacity or less, according to the current demand for heat. After reaching the set temperature, + hysteresis work goes into the post-combustion. If there is selected method of PID control, the controller controls the boiler continuously changing according to the time of administration, length of intervals between administrations and the power of the blower. As reaching the desired temperature of the boiler power should fall to stabilize at a level appropriate to the received power. The unit proceeds to the afterburner if the boiler water temperature, because of the very low heat demand, exceeds the specified operating temperature hysteresis value of work. 13

14 In the state of post-combustion fuel supply is switched off - operates only auxiliary burner feeder to eject the rest of the pellet. The blower operates with such power as for power reduced. After the complete combustion of fuel, the CLEANING process begins - the blower runs maximum power. After cleaning time (defined by the manufacturer), the burner goes into READINESS the duty cycle can start again automatically after fulfillment of the conditions of temperature. The controller automatically detects the lack of fuel or extinguishing of the flame for other reasons. If subsequent attempts to ingnite do not work, the burner is turned off. 2. Operation of the pumps. If the boiler's temperature is smaller than 6ºC, the anti-freezing function is on: all the pumps are on. All the pumps are on always after filing the boiler overheating alarm. Pumps: the central heating circulation pump. and charging DHW can be switched just after reaching the boiler's temperature even the last, put through the installer, the PUMP STARTS TEMPERATURE. If the boiler's temperature falls about 5 degrees below the PUMP STARTS TEMPERATURE all pumps will be switched off Operation of the central heating circulation pump The central heating circulation pump work depends on set DHW mode: a) If the SUMMER mode is on this pump is switched off. b) When the DHW PRIORITY is on, and the domestic hot water sensor has been installed, the pump is switched off for the time of loading the DHW tank. c) If it is set to WINTER mode, the pump is operating normally, but if the built-in manual valve is turned off and room panel "ROOMSTER 'is connected, the controller controls the heating circuit, by switching, as needed, the central heating pump Operation of DHW circulation pump. This pump is controlled solely by the time, based on settings in DHW CIRCULATION, and additionally turned off in ECONOMIC MODE (pkt.ii.10). Condition for turning on the pump is temperature of 35 C in a DHW tank Operation of the DHW loading pump Without the regard on the DHW PRESET TEMPERATURE, the pump is always off if the boiler's temperature falls below the water's temperature in the DHW tank, to prevent to cool down water in the DHW tank 14

15 Przygotowanie C.W.U. może się odbywać w trzech trybach: a) WINTER mode - It loads the DHW tank so that the minimum of the two temperatures is held: OPERATING TEMPERATURE and DHW PRESET TEM- PERATURE. The pump is switching on when the DHW temperature drops 5 C (standard value of the parameter DHW HISTERESIS, defined through the installer) below the DHW PRESET TEMPERATURE. The pump is switched off after reaching that temperature. b) PRIORITY mode - On the time of loading the DHW tank the OPERATING TEMPERATURE is placed on the level what the least 10 C higher than DHW PRESET TEMPERATURE.. Po wyłączeniu pompy ładującej BOILER OPERATING TEMPERATURE returns to the level set by the user. The pump is switched on if DHW sensor shows the temperature lower at 5 C (standard value of the parameter DHW HISTERESIS, defined through the installer) from the DHW PRESET TEMPERATURE. The pump is switched off after reaching that temperature. c)summer mode - charging pump works the same way as in the PRIORITY mode but the circulating pump is turned off. Attention!!! In the situation of DHW sensor failure, until replacement of the sensor the pump can still work in failure mode parallel with the circulation pump. Attention!!! Controller has built-in function of Legionella pneumophila neutralization, which can be found in hot water containers. Neutralization function will result in setting DHW temperature to 70 C with priority on Saturday between 2:00am and 4:00am.

Module selection to view or to change the parameters, make by selecting items on the list. After selecting the module will display a screen with the current configuration of the valve. 1. Modes of the valve operation. Each valve module can operate in different modes of operation, which is set in the parameter menu of the valve. You can select from the following configurations heating circuits: a) the shuttle valve supply underfloor heating 21

22 b) the shuttle valve power heaters c) the shuttle valve working on mixing return d) four-way valve supply underfloor heating e) four-way valve supply heating radiator or the entire substation 22

23 2.Cooperation the valve and the room panel. Each module is connected to the control valve Expert PID, with the exception of the valve is configured to work in return, can work with the room panel - ROOMSTER. In this case, the temperature of the feedwater of heating circuit is automatically adjusted based on the current room temperature and desired temperature. Information about connecting and correct use of the room panel is displayed on the valve`s screen in the form of a house icon with displayed current room temperature. 3. Edition the module parameters of the valve. To set the operating parameters of the valve, being in the valve`s screen, press. Displays a list of parameters to adjust. The following parameters are available: [1] TEMPERATURE SETPOINT depending on the configuration of the valve, temperature set point is set to for the heating circuit: - 3-W (three-way) floor or radiator - temp. Power, - 3-W return - temp. return, - 4-W (four-way) floor or radiator - setpoint temperature supply and return The set temperature for FLOOR mode is always limited to 40 C. If the panel ROOMSTER is connected, the power setpoint temperature setting is locked. [2] OPERATION MODE set one of five possible modes of mixing valve 3W (Tyree- way) FLOOR mode provides regulation of floor heating circuit, while reducing the maximum temperature of the water in circulation to. 3W RADIATOR mode provides quality heating control based on set temperature or outdoor temperature. 3W ON RETURN mode is used to ensure a minimum return temper- 23

24 ature to the boiler. In modes 4-W (four-way) FLOOR and RADIATOR, during adjustment, priority is to maintain the minimum return set temperature. Only after this condition the program allows the valve to open up and send a heating fluid for heating circuits. Attention! To correct adjustment four-way valve is required to connect two temperature sensors: supply and return. Return temperature sensor should be placed as close to the boiler. The manner of the heating system, in particular the place pumps, should ensure a continuous flow of water returning to the boiler lack of exchange cause incorrect measurements of temperature and mixing valve malfunction. [3] NAME OF THE SYSTEM - can be selected one of 20 predefined names for the heating circuit, in order to further distinguish if there will be more modules of valves. [4] TIME OF MOVEMENT it is the smallest amount of time that will move the valve actuator. Should be selected according to a full revolution of the valve. If TIME MOVEMENT is short and the time for a full rotation of the valve very long, the valve will be very slow to react to changes in temperature. If TIME MOVEMENT is too long compared to the time a full rotation, it will create fluctuations in temperature at the output of the valve, and may even make impossible to set desired temperature. [5] ADJUSTMENT RANGE - determines the range of temperatures before TEMPERATURE SETPOINT, at which the controller selects an automatically valve opening. Below SCOPE OF CONTROL valve is opened to maximum [6] WEEKLY PROGRAM - to set and enable and disable the weekly program of temperature correction for the heating circuit, in analogy to the setup described above, a program for the boiler temperature. IX. Error service. In case of error state like boiler overheating, refrigeration of the boiler, fire in the fuel container or sensor failure appropriate information will be shown on screen: a) Overheating the boiler - temperature of boiler s water above 92ºC. On the display appears the announcement of the boiler's overheating and the sound signal is generated. To chill the boiler switched off becomes blowing fan and feeder and turned on all pumps. When the temperature of boiler s water falls below 90ºC, the boiler comes back to the previous mode of the work. 24

25 b) Lighting oneself the fuel in the feeder or in the fuel container. The feeding device s temperature sensor, installed on the pipe of the feeder, controls his temperature. In the case of catching the fire the fuel in feeder or pipe that connects feeders,.possibly sensor failure, the display appears the announcement of the feeder failure and generated the continuous sound signal. The notification of this alarm causes disconnection the blower and the feeder and permanently incorporate the burner`s feeder. After the end of the alarm, the burner is OFF. d) Damage of the boiler s temperature sensor. Displayed becomes the screen with suitable information and the sound signal is generated. Switched off becomes blowing fan and feeder and turned on all pumps. The damage of the boiler's temperature sensor makes impossible the more far work of the controller. You should exchange the damaged sensor on new (one can temporarily use the DHW sensor as the boiler's sensor). e) Damage of the DHW temperature sensor. Displayed becomes the screen with suitable information and the sound signal is generated. After stepping out this breakdown the work of the boiler still is realized in the way provided for the work without the sensor. You should install the new sensor or, through switching off and renewed switching on the controller, give up the DHW sensor. f) Damage of the chimney temperature sensor. Displayed becomes the screen with suitable information and the sound signal is generated. Further operation of the burner is not possible - the burner switches to OFF.

30 ume based on PID calculation program, according to the demand for power boiler. This adjustment takes place in the range between the minimum allowable power and RATED POWER. The displacement control mode burner, depending on the current demand for power can operate at rated power or POWER REDUCED. [3] DHW HISTERESIS 2 10 [ C] Parameter describes permissible variance of temperature in DHW water container. DHW pump turns on when water temperature get lower than DHW TEMPERATURE minus DHW HISTERESIS. Too low values of this parameter result in too frequent turning on DHW pump and unstable work of boiler. Recommended values are 3 5 C. [4] DHW DESINFECTION. active / inactive Parameter allows turning on or off function of germs neutralization in DHW container. While active, once a week at Saturday from 2:00am to 4:00am DHW temperature is automatically set for 70 C and DHW PRIORITY is turned on. This parameter if turned off by default. [5] RATED POWER 6 30[kW] The controller is pre-configured to work with the strength of the burner plate. After installing the burner in the boiler must be adjusted to the maximum output power rating of the burner boiler. [6] REDUCED POWER 6 30[kW] Parameter specifies the power level adjustment mode reduced displacement. Additionally, during the post-combustion blower blows with the power corresponding to the reduced power of the burner. The recommended setting is approx. 50% POWER RATED. [7]HYSTERESIS WORK 1 10 [ C] This parameter defines the acceptable range of fluctuation of water temperature in the boiler. Regardless of the mode of regulation, if the boiler water temperature exceeds the set hysteresis work, burner enters the READY state, and died previously fuel and cleaning the grate. The burner will go to LIGHTING only when the water temperature falls below the setpoint hysteresis work The recommended setting is 3 5 C. [8] STARTING DOSE OF FUEL [s] This parameter defines the time before lighting the fuel supply, indirectly the size of the initial amount of fuel. This time should be set the starting dose of fuel weighs g. 30

31 [9] SUPPLY TO CIRCUIT Here set the heating circuit's power in the case of three-way valve connected module. If you choose the option that the boiler is not supplying directly any of the heating circuit (ie, that all heating circuits are powered by the valve modules), then the required temperature of the boiler is determined by the valve module. If the are several valve modules, the temperature of the boiler shall be established according to the valve, which needs the highest temperature.. [10] BUILT-IN VALVE. Enables or disables built-in mixing valve module If the built-in valve is switched off there is a possibility of direct cooperation between the controller and room`s controller, called ROOMSTER.involving the appropriate on and off the central heating. circulation pump, Attention! Before the start of the heating season it is recommended to purge photo-optical element located in the burner and control the correctness of its actions 31
