To avoid electrical shock, connect the device to a grounded mains socket (with grounding pin). The socket must be grounded by an authorized electrician. When connecting a device, make sure that this will not overload the electrical circuit. Avoid connecting the device to the same circuit with motors and other machines generating impulse interference (e.g. washing machines, refrigerators,...). Before connecting any cables and peripherals to the device, you must disconnect power supply. To completely disconnect the power supply, pull out the plug from the socket, in particular when left unused for a long period of time. Protect the power cord from damage, it should be folded in such a manner so that no-one can stand or put any objects on the cable. Any connections must comply with electrical wiring diagram and with national or local regulations applicable to electrical connections. Prior to any maintenance works, disconnect the device from power supply. To clean the burner cover, do not use petrol, solvents or other chemicals that may damage the housing. We recommend using a soft cloth. 3 P a g e

4 In any circumstances do not use the device with its power cord damaged. A damaged cord must be replaced with a new one with the same parameters as the original one Requirements for boiler room NOTE! There is a danger of CO carbon monoxide poisoning, when the boiler is located in a room with insufficient supply of fresh air. A set (a burner, a tank, a feeder, a boiler) should be placed in a separate room, situated as centrally as possible in relation to the heated rooms. The boiler room entrance door must open outwards, be made of non-combustible materials and be 0.8 m wide at least. The floor in the boiler room should be made of non-combustible materials or covered with a 0.7 mm thick steel sheet, to the distance of at least 0.5 m from the edge of the boiler. The boiler should be placed on a foundation made of non-combustible materials, protruding 0.05m above the floor level, reinforced with angle iron. The room where the burner is operated should be lit with artificial light, and natural light is also recommended. The distance from the boiler to the walls should be such as to allow access during operation, cleaning and maintenance. The minimum distance between the boiler and the opposite wall: 1m. The minimum height of the boiler room: 2.2m; the height of 1.9 m is permitted in existing buildings with sufficient ventilation (supply and exhaust). Installation in wet areas or with high humidity is definitely forbidden. Accelerated corrosion can quickly lead to damage Distance from flammable materials During installation and operation, a safe distance of 200 mm from flammable materials must be kept; for flammable materials with C3 flammability degree, which burn quickly and easily even after removal of the ignition source (e.g. paper, paperboard, cardboard, wood, plastics), the distance is doubled, i.e. up to 400 mm; if flammability is not known, a safe distance must also be doubled. The degree of flammability of building materials and products A non combustible B non flamable C1 flameretardant C2 combustible average C3 flammable Building Materials and Products sandstone, concrete, bricks, plaster, mortar, masonry, ceramic tiles, granite wood-cement boards, fiberglass, mineral wool Beech tree, oak wood, plywood, felt pine, larch and spruce wood, cork boards grated trees, rubber flooring Asphalt plywood, pulp celluloid, polyurethane, polystyrene, fiberboard, polypropylene, polyethylene, dry grass, cork, cardboard 3. Basic information 3.1. PELETIX II+ burner description burner automatic start simple operation of the burner at two power levels flame control is carried out by a photocell low thermal inertia at start and stop low power consumption available multiple heating circuits control by additional modules (optional) available control via the Internet / GSM by additional modules (optional) available option of external shortcut thermostat control available 2 additional buffer charging sensors (optional) burner temperature control ensures top level of security 3-stage fuel ignition eliminates the risk of gas explosions during ignition AUTOSTART after power failure ensures top level security AUTOSTART after power failure - last settings saved in memory air is divided into primary air and secondary air - CO emission level reduced to the level of gas and oil burners emission self-air cleaning function, automatically removes the sludge from the burner s grate - this feature does not appear in burners with gravity chute. The burner is protected in four ways against flame backward movement into the fuel tank: thermal sensor (thermal breaker) placed in the burner body - activation of the sensor causes immediate shutdown of the burner system (activation temperature is 85 C. Restarting the device is possible immediately after the user has examined the device. In case of incorrect operation, signs of malfunction, a qualified serviceman must be called in immediately. In such case, the users are definitely discouraged from starting the machine, as it may pose a risk of damage to property and / or hazards to health or life. If you do not find any problems with continuing the operation, the burner will continue after restart of the boiler/ burner on the control panel (control cabinet). the structure of the fuel feeding tube (a flexible hose) between the fuel feeder and the hopper of the PELETIX II+ burner - it is designed as the "weakest" component of the fuel supply system. The underlying idea is to let the tube burn through in case of emergency. It is a reliable and safe solution, provided that all the procedures and requirements contained in this manual are maintained. the burner s feed duct inclined downwards serves as protection against exposure to flame formed in the burner to contact with the fuel contained in the tray. the photocell in the burner controls the flame in the burner. 4 P a g e

Connections must be made with the device disconnected from power. Connections should be carried out by an adequately qualified technician. General information about electrical installation of the regulator, the boiler and boiler accessories 5.1. Installation of the burner in the boiler The PELETIX II+ Burner is intended for installation in a DOR/S111/Solid 2000 boiler. Devices are to be installed only indoors. After selecting the place of installation, make sure that it meets the following conditions: The location must be free from excessive humidity and flammable or corrosive vapors Installation of the unit must ensure compliance of the entire burner with the law Installation of the device must not be carried out in the vicinity of high-power electrical equipment, electrical machines or welding equipment. The installation site ambient temperature does not exceed 75ᵒC and should not be lower than -25 C. non-condensing humidity should range from 5% to 95% TO INSTALL THE BURNER IN A BOILER PLEASE REFFER TO THE SET INSTALLATION MANUAL Feeder installation NOTE! Do not insert any objects into a rotating screw feeder, especially fingers! Install the feeder with the chute above the burner, the inclination of the plastic tube enclosed should be sufficient enough for the fuel to slide down to the burner freely. Place the screw feeder in the intended position on the pellet tray. For a spiral feeder, make sure it has not raised by more than 45. In the case of a tray with a complete helix (spiral + pin), the angle may be up to 75. Fill the hopper with pellets so that at least the inlet to the tray is completely covered with the fuel. a. The boiler room should be equipped with 230V / 50Hz power system, made in compliance with the applicable regulations. b. The power system must end with a socket equipped with a protective contact c. All connections made must comply with electrical wiring diagram, national and local regulations applicable to electrical codes. d. ECU must be connected to a separate electrical circuit equipped with a suitable circuit breaker and RCD. DO NOT CONNECT ANY OTHER DEVICE TO THIS LINE. e. The person responsible for installation and any electrical repairs should be an experienced technician and be authorized to do it. f. Any repairs can be made only with disconnected power supply. g. The boiler temperature sensor should be placed in an immersion sleeve in the water space of the boiler and secured against movement (falling out). The remaining part of the wire should be rolled up and placed in such a way so that there is no danger of accidental or spontaneous ejection of the temperature sensor from the sleeve (the cable, for example, can be placed on the outer housing of the boiler). h. The STB sensor must be placed in the same immersion sleeve as the boiler temperature sensor and secured against movement (falling out). The STB sensor cannot be pressed or bent as it s temperature characteristic will be changed and it will not work properly any more. i. The wires and STB capillary in any case cannot be broken and/or bent, they should have intact external insulation all along each wire. j. You cannot let water, moisture and/or dust get inside the device, as it can cause a short circuit, electric shock, fire or damage to the device. k. Ensure proper ventilation of electrical appliances (e.g. a controller), patency of vents and free flow of air around the unit. l. Electrical equipment (controller, burner, sensors) are intended for indoor installation. 8 P a g e

9 5.4. Fuel tank A fuel tank may be for example a barrel or a special tray adapted for a space that is available. However, you should always adhere to fire safety regulations and recommendations of a chimney sweeper. The tank should have a lid with a seal. You should also seal a connection between a feeder and a tank. It is recommended to use original tanks adapted to the burner PELETIX II+. Store pellets in a dry place to keep their original, hard consistency. Damp pellets are soft and crumbling. Do not use damp pellet - it will cause malfunction of the burner and/or other problems. 6. Chimney The boiler s performance depends largely on proper height and diameter of the chimney. Before connecting the boiler to the chimney, it should be checked for sufficient cross-section (flue pipe diameter should not be smaller than the diameter of the boiler s flue and w/o any other heating devices connected to the chimney). NOTE! The chimney must be properly sealed and insulated, to avoid formation of water vapor and tar in the chimney due to reduction of its capacity. Normal chimney draft is 20 Pa. If the negative pressure is too high, a draft stabilizer should be installed on the chimney. Negative pressure in the combustion chamber is a necessary condition for proper operation of the burner, and it must be formed by the chimney installation. The required values are contained in the technical data of the burner PELETIX II+. Chimney should discharge the products of combustion from the boiler to the atmosphere. The chimney system produces the draft that depends on: a temperature gradient between the temperature of the flue gas and ambient temperature (difference in density and pressure) smoke flue length shape of the flue (elbows, inclinations, draft shut-off, etc.), cross-sectional shape of the chimney duct size of the chimney s section (it is not advisable to mount a chimney with the cross-section smaller than the diameter of the stack) roughness of the inner surface of the chimney s duct purity of the flue tightness of the flue (gaskets, sealing joints, etc.) presence and workmanship of the chimney s duct insulation variations in environmental conditions (temperature, pressure fluctuations related to air flow, the shape of the roof, chimney s location in relation to external barriers - buildings, etc.) EU standards and regulations define the materials that can be used for chimney construction and the manner of their application. Chimney sizes are defined in local regulations concerning technical conditions that should be fulfilled by buildings and their location. Please follow the EU and national standards which regulate chimney condition, calculation and maintenance. 7. Cleaning and maintenance NOTE! Cleaning and maintenance of the burner PELETIX II+ can take place only when the burner is burned out, cooled and disconnected from power supply. Be careful of hot surfaces of the burner - risk of scalding. NOTE! To maintain high efficiency, the burner should be regularly cleaned and maintained. You should regularly remove soot, tar and ash deposits from the burner grate. NOTE! After each cleaning of the burner, make sure the grate is installed correctly! Inaccurate placement of the grate The tongue under the grate should be embedded in a recess in the grate case - can cause damage to the burner! 7.1. Maintenance Burner control timeliness is associated with the control of the entire boiler room (operation of the boiler and safety equipment). A. A monthly inspection a. Water pressure control b. Safety valve function control c. Safety devices function control d. Tightness control of all connections and closures e. Control of supply and exhaust ventilation B. Small inspection (every 6 months) a. control of tightness of seals and sealing cords b. control of boiler elements - door insulation c. safety devices control (safety valve, STB, etc.) d. Exhaust gas analysis (if significant increase in the exhaust gas temperature is observed, clean the exhaust part of the boiler) C. Large maintenance inspection (every 12 months) performed by a serviceman a. control of the tightness of seals and sealing cords b. The exhaust gas analysis c. The burner control, automation settings control 9 P a g e

10 When the boiler / burner is out of operation for a long time, the residual oxygen contained in the boiler water and the oxygen that gets into the water from the air is, in the presence of carbonic acid, highly corrosive. During inactivity of the boiler that lasts longer than one week, you should take up protective measures. You should regularly remove soot, tar and ash deposits from the combustion chamber, all the walls of the boiler s heat exchanger (partitions, etc.), as well as from the PELETIX II+ burner s grate. The boiler and burner should be cleaned depending on the degree of contamination, but not less frequently than every 2 weeks (the burner - every 1 week). Ash should be removed depending on the degree of filling of the combustion chamber Cleaning The efficiency of the burner operation is closely related to the effectiveness of supplying combustion air. Pollution of the burner can effectively reduce the quality of the burner, reduce its efficiency and accordingly disturb the quality of your heating system. Regular and proper maintenance of the boiler, burner and the equipment is a prerequisite for the proper and safe operation of the system and reduced fuel consumption. At least once a year and after each stoppage of the boiler, call the appropriate Authorized Service for inspection. During continuous operation of the boiler, it is recommended, depending on the degree of contamination, but at least once every two weeks, to clean the flue of the boiler and the burner s grate (1 per week). During the operation, the heat exchanger gets polluted, which causes the exhaust gas temperature to rise at the outlet of the boiler and reduces the efficiency, which may also affect the quality of the burner (the efficacy of the fan). To clean the burner, perform the following steps a. Shut the boiler off (wait until complete extinction of the burner) b. Disconnect the boiler from the mains and wait until the boiler cools down. c. Disconnect the burner from the boiler and the power system, then make the appropriate cleaning works, in compliance with the schedule PELETIX II+ burner cleaning works timeliness Weekly - cleaning of the burner grate (remove the grate from the burner and clean it (remember to clean the patency vents). Monthly - external cleaning of the engine and fan (especially fan blades) Quarterly - cleaning of the space between the burner grate unit and the outer tube unit. 8. Controller ST Description Temperature controller ST 717 is intended for use with pellet boilers for central heating. It controls water circulation pump, domestic hot water pump, heater and main and auxiliary fuel feeders. It can operate with two 3- or 4-way valves, room controller, GSM module or Ethernet module. The advantage of the controller is the ease of use. The user can change all parameters using a pulsar knob. Another advantage is a large and easy-to-read display where the current boiler operation is shown. Each controller should be customized to individual user s needs, depending on the type of fuel and CH boiler used. BADO does not accept liability for incorrect settings Basic terms Ignition this phase is initiated by the user. The first stage involves feeding fuel to the furnace. It is followed by the ignition. The igniter is activated at full power and remains active until flame is detected. Maximum output after the ignition is completed, the controller enters maximum output operation mode and the display shows the following message: MAXIMUM OUTPUT. It is the primary mode of controller operation in which the fan operation and fuel feeding is automatically controlled, aiming at the preset temperature. Minimum output after the pre-set temperature has been achieved, the burner turns into the minimum output mode. This prevents the burner to burn out and ignite too many times. If the temperature falls down lower than hysteresis, the burner will turn into maximum output mode again. If the temperature rises unexpectedly by more than 5ᵒC above the pre-set value (default setting), the CH boiler switches into burn out. Burn out this phase is initiated by the user. The fuel feeding is stopped and the flue gas fan is active. When the flames fade, the cooling process is initiated - the flue gas fan and the pumps (optionally) remain active. It is followed by the cleaning process during which the fan and the pumps are switched off. Main page During normal operation of the controller the graphic display shows the main page. Depending on the operating mode, its corresponding main screen is displayed: To move to the first level menu, press the pulsar knob. The display shows the first tree menu options. To access more options, turn the knob. To select a function, press the knob. To change parameters, follow the same procedure. For your changes to be entered it is necessary to confirm them by pressing the pulsar at CONFIRM. If you do not want to make any changes within a given function, press the pulsar at CANCEL. To exit the menu, use the EXIT key. Screen view You can use this function to select one of four thermoregulator operation main screens. CH screen - displays the current mode of operation of the boiler. 10 P a g e

After the burner is filled with fuel, the boiler enters the ignition phase, where the flue gas fan operates at the speed set for the ignition stage. The igniter is started and operates at full power. The operating parameters remain unchanged until the flame is detected (approx min.). The fan still operates at the ignition power rate. Afterwards, the boiler enters the working mode where both fan and the feeder work in automatic mode. 11 P a g e

12 Tank full This function is used when the fuel container is being filled. After the container is fully filled, the message >> Container full >> should be highlighted and confirmed. From that moment on, the fuel level displayed in the main screen will be updated. CH set temp. This option is used to adjust the set boiler temperature. The user may change the temperature range in the boiler from 45⁰C to 80⁰C. The set CH can also be changed directly from the main controller screen by turning the pulse generator knob. DHW set temp. This option is used to adjust the set value of the hot utility water temperature. The user may change this temperature in the range from 40⁰C to 75⁰C. Manual mode For the user s convenience, the regulator has been equipped with a Manual operation module. In this function, each executive device (the feeder, the blow-in, the CH pump, the HUW pump, blow) is activated and deactivated independently of the other devices. Pressing the pulse generator activates the engine of the chosen device. This device remains activated until the pulse generator is pressed again. The blow-in power, where the user has the possibility to set any rotational speed of the fan in manual operation, is additionally available. Manual heating When this option is activated, the feeder and the fire sensor are disabled. Fire-up option is no longer available in the controller menu. Only the fan remains active. Maximum output Feed time This option is used to define the operation time of the fuel feeder. The time should be adjusted to the type of fuel and CH boiler used. Feed pause This option is used to define the pause time of the fuel feeder. The time should be adjusted to the type of fuel and CH boiler used. Incorrect operation and pause time may lead to ineffective operation of the CH boiler e.g. unburnt fuel left or failure to reach the pre-set temperature. Appropriate pause and operation time ensures efficient operation of the CH boiler. Blow force This function is used to control fan speed. The setting range is % (it may be regarded as the fan speeds). The higher the speed is, the faster the fan operates. 10% is the minimum fan speed, whereas 100% is the maximum fan speed. Initially, the fan always operates at full speed, which enables successful activation even if the motor is dusty. Minimum output Feed time This option is used to set the operation and pause time of the feeder and the fan (simultaneously) when the CH boiler remains in sustain mode. Feed pause This option is used to define the pause time of the fuel feeding in the sustain mode. Incorrect operation and pause time may lead to further temperature increase, unintentional CH boiler damping or cause fuel ignition hazard in the fuel tank. Blow force This option allows the user to set appropriate operation and pause time of the fan in sustain mode (the so called blow-by). Week based regulation The controller enables the user to program controller operation in a weekly cycle. It is possible to select hours when the CH boiler is to be damped (Operation schedule) and program daily changes of the CH boiler temperature as well as DHW temperature (CH boiler weekly control and DHW weekly control). Operation schedule This option concerns the CH boiler. It enables the user to set the periods of CH boiler operation and inactivity on particular days of the week, with the accuracy of 30 minutes Set mode 1 option. After programming each day of the week, the user activates Mode 1 option. Delete data option enables the user to delete the operation schedule settings. CH week program and DHW week program These options enable the user to set daily changes in the preset temperatures (for particular hours and particular days of the week) for both the CH boiler and DHW tank. The pre-set temperature deviation range is +/-10ᵒC. Step I: First the user must set current time and date (Installers menu>time settings) Step II: The user sets the temperatures for each particular weekday (Set mode 1): Monday-Sunday. In this mode, specific time and the requested deviations from the pre-set temperature should be defined (by how many degrees the temperature should rise or drop at a given time) for each day of the week. Additionally, to facilitate the use of this function, it is possible to copy the settings. Example: Monday set: 3:00 AM, temp -10ᵒC (temperature change 10ᵒC) set: 4:00 AM, temp -10ᵒC (temperature change 10ᵒC) set: 5:00 AM, temp -10ᵒC (temperature change 10ᵒC) In this case, if the pre-set temperature of the CH boiler is 60ᵒC, from 3:00 AM to 6:00 AM on Monday, the preset temperature will drop by 10ᵒC, so it will be 50ᵒC. Instead of setting the temperature for particular days, mode 2 enables the user to set the temperature for all working days (Monday-Friday) and for the weekend (Saturday-Sunday) Set mode 2. Step III (Mode): The user activates the previously defined mode (Mode 1) or deactivates weekly control completely. 12 P a g e

13 After the mode has been activated, the value of the currently set deviation will be flashing on the controller main page, informing the user that the weekly control is active. Delete settings function is used to delete the previously set parameters of the weekly program in order to introduce new settings. Pump modes In this function, the user selects one of four options of the boiler s operation: House heating By choosing this option, the regulator switches to heating the house only. The CH pump starts to work above the pump activation threshold (preset to 40⁰C). Below this temperature the pump stops working. DHW priority In this mode, the DHW-tank pump (DHW) is turned on first, until the set temperature is reached. After reaching the set DHW-tank temperature, the HUW pump shuts down and causes activation of the CH pump. The CH pump operates constantly, until the moment when the temperature at the DHW-tank drops below the set value. At that time, the CH pump shuts down and the DHW pump is activated In this mode, operation of the fan and the feeder is limited to 62 degrees in the boiler, since this prevents the boiler from overheating. reached. When the temperature drops below the pre-set buffer up value, the device is activated again. Installers menu See chapter 9.4 Service menu Enter a four digit code to access the controller s servicing functions. Such a code is in possession of the manufacturer of the boiler. For details see additional manual. Factory settings This function enables the user to restore factory settings. Software version The boiler manufacturer s logo along with the version of the regulator software will appear upon activation of this option on the display. NOTE: The boiler should be equipped with return valves on the circuits of the CH pump and the HUW pump. The valve mounted on the HUW pump prevents hot water from being sucked out of the DHW-tank. Parallel pumps In this mode, both pumps work simultaneously above the pump activation threshold temperature (preset to 40ᵒC). The CH pump operates continuously and the DHW pump shuts down after reaching the temperature set at the DHW-tank. The DHW pump will be re-activated when the DHW-tank temperature drops below the set value (see DHW hysteresis in the installer s menu). NOTE: In this mode, one should install a three-way valve or another mixing valve causing maintenance of a different temperature in the DHW-tank and of a different in the house) Summer mode After activation of this function, only the DHW pump, whose task is additional heating of the DHW-tank, operates. This pump is activated above the set activation threshold (see the pump activation temperature function) and operates until the set temperature is reached. The pump will be activated again when the temperature drops below the set value and the set hysteresis. In the summer mode, one sets only the set temperature in the boiler which additionally heats the water in the DHW-tank (the set boiler temperature is at the same time the set DHW-tank temperature). Buffer top set temperature, bottom set temperature This option should be selected when the CH boiler is to heat the buffer. CH pump serves as the buffer pump. The pump remains active until the pre-set buffer down temperature is 13 P a g e

Temperature settings Parameters in this submenu are used to set the temperatures: Room regulator GSM module Internet module Clock Date Off Standard room regulator TECH room regulator CH pump room regulator On Off see internet module manual Boiler hysteresis This option is used to set the hysteresis of the pre-set CH temperature. It is the difference between the temperature of entering the sustain mode and the temperature of restoring operation mode (for example: when the pre-set temperature is 60ᵒC, the hysteresis is 3ᵒC, entering sustain mode takes place at the temperature of 60ᵒC whereas returning to the operation mode takes place at 57ᵒC). DHW hysteresis This option is used to set the hysteresis of the pre-set water tank temperature. It is the maximum difference between the pre-set temperature (desired temp. of the water tank at which the pump is switched off) and the temperature of returning to operation mode. Pulsar sensitivity Language version Dispaly contrast Stoker factor Pump activation temperature This option is used to define the temperature of CH pump and DHW pump activation (temperature measured at the CH boiler). Below this temperature value, both pumps remain inactive whereas above this value the pumps are enabled and operate according to the current operation mode (see: pump operation modes). Boiler output Factory settings The functions in the installer s menu should be set by the person installing the boiler or by the manufacturer s service.

Switch off This feature allows you to temporarily make the valve inactive. Temperature control This feature allows you to temporarily make the valve active. Opening time In this function, the time of full valve opening is set, in other words, how long it takes for the valve to open to 100%. This time should be selected according to the valve servomotor (stated on the rating plate). Single step In this function, the percentage unit of valve opening stroke is set, that is the minimum percent of opening or closing the valve is expected to execute. Minimum opening In this function, the minimum value of the valve opening is set. Below this value, the mixing valve will not close any further. Valve 1 / Valve 2 Return protection Additional sensors Pump activation Room regulation device Factory settings Valve removal NOTE: Controlling the valve is possible only after purchasing an additional ST-61 control module and connecting it to the controller, which is not included to the room regulator as a standard feature. Two ST-61 modules should be connected to control two valves. This option is used to set the operation of the mixing valve. To make sure that the valve works properly in accordance with the user s expectation, is should be registered by entering the module number (this is the number of the valve On Off Min. return temperature Max. return temperature Own From the main Always Never Above treshod CH pump activation temp.

Weather-based control This function is possible only after purchasing an additional ST-431 control module and connecting it to the controller. To activate the weather function, external sensor should be placed in the place which is not isolated and not exposed to atmospheric impacts. After installation and connection, a sensor should have the function of Weather sensor activated in a controller menu. To make sure that the valve works correctly, the set temperature is set (behind the valve) for three intermediate external temperatures: Set temperature threshold 1-20ᵒC; Set temperature threshold 2 0ᵒC; Set temperature threshold 3 +20ᵒC. Below, an example for the valve set as Type> floor: Heating curve this is a curve, according to which the preset controller temperature is determined, on the basis of external temperature. In our controller, this curve is constructed on the basis of three points of set temperatures for the respective external temperatures. Set temperatures must be determined for external temperatures of 20ᵒC, 0ᵒC and 20ᵒC. The more points constructing the curve, the greater its accuracy, which allows its flexible shaping. In our case, three points seem a very good compromise between the accuracy and the ease in setting the course of this curve. Return protection This function permits setting the boiler protection against too cool water returning from the main circulation, which could cause low-temperature boiler corrosion. The return protection operates in the way where, when the temperature is too low, the valve is closed, until the short circulation of the boiler reaches the appropriate temperature. This function also protects the boiler against dangerously high temperature of return in order to prevent boiling of water. 15 P a g e

16 Additional sensors When two mixing valves are used and you select this function, you will be able to select the sensors from which the temperature data is to be retrieved for a valve (for return and outside temperature sensors). Temperatures can be retrieved from the sensors of the valve being set (Own) or as per the controller sensors (Main controller). Set valve change The setting determines the number of degrees the valve temperature will rise or drop with a unit change of the room temperature (see: Room temperature difference). The function is active only with TECH room controller and is directly related to the Room temperature difference parameter. Room temperature difference The setting determines the unit change in current room temperature (accurate to 0.1 C) which triggers the predefined change in the valve pre-set temperature (The function is active with TECH room controller only). Example: setting: Room temperature difference: 0.5ᵒC setting: Modification of the pre-set valve temperature: 1ᵒC setting: Pre-set valve temperature: 40ᵒC setting: Pre-set room controller temperature: 23ᵒC Case 1. If the room temperature rises by 0.5ᵒC to 23.5ᵒC, the valve will be partially closed to decrease the temperature by 1ᵒC to the pre-set value of 39ºC. Case 2. If the room temperature drops by 1ᵒC to 22ᵒC, the valve will partially open to increase the temperature by 2ᵒC to the pre-set value of 42ᵒC. Factory settings This parameter allows you to restore the mixing valve settings saved by the manufacturer. By restoring the factory settings you will not change the valve type setting (central heating or floor type). Valve removal This function is used for a complete removal of the valve from the controller memory. Valve removal is used e.g. at disassembling the valve or module replacement (reregistration of a new module is necessary). Room regulator It is possible to connect a room regulator to the ST-717 controller. The parameters in this submenu are used to configure the operation of the room regulator: Switched off. Select this option to disable communication between the room regulator and the ST-717 controller. Standard regulator. This option should be selected if the room regulator connected to the controller is a two-state regulator. Such a regulator sends a signal to the main controller informing about sufficient or insufficient temperature in the room. TECH regulator. This option should be selected if the room regulator connected to the controller uses RS communication. Such a regulator enables the user to view current CH boiler parameters and change some of the settings e.g. the pre-set temperature of the CH boiler or the pre-set DHW temperature. Room regulator device This option is used to configure the room regulator operation: Switched off the room regulator status does not influence other settings. CH boiler when the pre-set room temperature is reached, the pre-set CH boiler temperature is reduced; CH pump when the pre-set room temperature is reached, the CH pump is disabled. Software version. This parameter concerns the room regulators with RS communication. When this function is selected, the controller display shows the software version used in the room regulator. WARNING: No external voltage may be connected to the room regulator output. GSM module (additional accessory, not part of a standard delivery) NOTE: This type of control is possible after purchasing the additional control module ST-65, which is not attached to the regulator as a standard feature, and connecting it to the controller. The GSM module is an optional device cooperating with the boiler controller, enabling remote control of the boiler operation with the use of a mobile phone. The User is notified with a text message on each alert of the boiler controller, and by sending an appropriate text message at any time, he or she receives a return message with the information on the current temperature of all sensors. After entering an authentication code, it is also possible to remotely change the set temperatures. The GSM module can also operate independently from the boiler controller. It has two inputs with temperature sensors, single contact input for use in any configuration (detecting short circuit/opening of contacts) and one controlled output (e.g. possibility to connect additional contactor to control any electrical circuit). When any temperature sensor reaches the preset deactivation temperature, maximum or minimum, the module will automatically send a text message with such information. It is similar in the case of a short-circuit or opening of contact input, which may be used e.g. for simple protection of property. If ST-717 controller is equipped with an additional GSM module, in order to activate this device, it is required to start the activated option (MENU> Installer menu> GSM module> Activated. Internet module (additional accessory, not part of a standard delivery) NOTE: This type of control is possible after purchasing an additional ST-500 control module, which is not attached to the regulator as a standard feature, and connecting it to the controller. The Internet module is a device enabling remote control of the boiler via the Internet or local network. On the home computer screen, the user controls the condition of all boiler system devices and the operation of each device is presented in the animated form. Apart from the possibility to view the temperature of every sensor, the user has the possibility of introducing changes of the set temperatures for both the pumps and the mixing valves. After activating the Internet module and selecting the DHCP option, the controller will automatically download from the local network such parameters as: IP address, IP Mask, Gateway address and DNS Address. In the case of any problems with downloading network parameters of the existing network, there is a 16 P a g e
