39 TECHNICAL SERVICE Новый алюминиевый радиальный (спиральный) первичный теплообменник. Оптимальные форма и размеры, обеспечивающие максимальный КПД котла и уменьшающие вероятность образования накипи. Материал теплообменника – алюминиевый сплав без примесей железа и меди, устойчивый к воздействию кислотосодержащей воды. Масса теплообменника гарантирует безинерционный нагрев ГВС. Технология производства теплообменника исключает сварку для предотвращения электрохимической коррозии. Спираль теплообменника отливается под давлением на автоматизированной конвейерной линии. Внешняя поверхность теплообменника обрабатывается на каландре. Топочная группа

40 TECHNICAL SERVICE The newest and most important component in the combustion engine is the heat exchanger. Its correct dimensioning and shape directly determines the efficiency of the boilers (flue side exchanging surface, water side exchanging surface) and its performances in terms of residual head available towards the system (loss inside the pipe, limestone). Its material (aluminium based alloy with low percentage - 0 %- of copper and iron) wass chosen to resist in the time even in an acid ambient (around 4 pH). Its mass determines the rapidity (inertia) in stisfying the DHW needs (confort). The coil is built without any welding, to avoild problems related to eventual elettrochemical corrosion.

92 TECHNICAL SERVICE In this new generation of PCBs the functioning and the adjustment to the system needs can be called by parameter, as on the MCBA. There are 2 different type of parameters: DYNAMIC parameters SERVICE parameters Parameters

93 TECHNICAL SERVICE DYNAMIC parameters: those parameters that can be changed in real-time by the end user (on- off, set-point, season). No special procedure is needed (on-off button, encoder, KLIMA button) to set. SERVICE parameters: are the parameters that substitute the old jumpers or that adapt the boiler to the system characteristics and needs. Are set by the factory to determine the boiler configuration (i.e. only heating), or by the Service in the field to optimise the boiler functioning (i.e. absolute DHW thermostats), or even in the spares PCBs for the substitution. They are divided into: GENERIC PARAMETERS SETTING (ADJUSTMENT) PARAMETERS. Parameters

94 TECHNICAL SERVICE GENERIC parameters: (PASSWORD) 53 To access to these parameters follow the hereunder procedure: 1. Set the boiler in OFF (the display visualises--) 2. Push at the same time KLIMA and INFO for 1 second, until the display (4-digits) visualises CODE and 00 in turn. 3. Push KLIMA and set with the DHW ENCODER the password 53. Confirm with KLIMA. 4. On the 2-digit display will appear the number of the parameter, while on the 4-digit will appear its value. REMARK: if a wrong PASSWORD is set, the boiler will go back automatically to pt. 2. Repeat the procedure with the correct PASSWORD. Parameters

95 TECHNICAL SERVICE To modify the parameter value: push KLIMA: the parameter value blinks. Set with the DHW ENCODER the desired value. Confirm your choice pushing again KLIMA. Now to change number of parameter, use the DHW ENCODER. To go out from the procedure push INFO or wait for 10 seconds. IF ON/OFF/RES is pushed, the boiler will go out from the procedure, but NO PARAMETER WILL BE SAVED. Parameters

101 TECHNICAL SERVICE Parameters PASSWORD 18

102 TECHNICAL SERVICE Parameters PASSWORD 18 Detailed description of parameters and functions: HP The HP function allows to modify, only if strictly necessary, the value of the ABSOLUTE maximum fan speed and consequently the maximum power of the boiler. WE CANNOT GUARANTEE THE WELL FUNCTIONING OF THE BOILER IF IT WILL BE SET TO AN HIGHER VALUE THAN THE ONE SHOWN IN THE BOOKLET! LP The LP function allows to modify, only if strictly necessary, the value of the ABSOLUTE minimum fan speed and consequently the minimum power of the boiler. WE CANNOT GUARANTEE THE WELL FUNCTIONING OF THE BOILER IF IT WILL BE SET TO A LOWER VALUE THAN THE ONE SHOWN IN THE BOOKLET! SP The SP function allows to modify, only if strictly necessary, the value of the fan speed during the soft light procedure. WE CANNOT GUARANTEE THE WELL FUNCTIONING OF THE BOILER IF IT WILL BE SET TO A DIFFERENT VALUE THAN THE ONE SHOWN IN THE BOOKLET! Differences between Hp, LP and PAR.23 and PAR.24: The parameters HP and LP are correspondent to the fan ABSOLUTE functioning limits (DHW), while PAR.23 and PAR.24 can be set only within (at limit equal to) HP and LP and are only related to CH functioning.

103 TECHNICAL SERVICE Parameters PASSWORD 18 HH The HH function is necessary to carry out the combustion analysis, or the set the gas valve in order to obtain the CO2 nominal percentage at the maximum power. Using this function the boiler will work continuously for 15 min at the maximum power, related to PAR.1, PAR.2 or HP. During this function the boiler wont modulate according to the CH set-point. In case of floor heating systems, or whenever the CH system is not sufficient to exchange all the heat, can be suggestible to open all the DHW taps at the maximum flow after removed the diverter valve.

104 TECHNICAL SERVICE Parameters PASSWORD 18 LL The HH function is necessary to carry out the combustion analysis, or the set the gas valve in order to obtain the CO2 nominal percentage at the minimum power. Using this function the boiler will work continuously for 15 min at the minimum power, related to PAR.1, PAR.2 or HP. Attention: see the remark for function HH. MM When accessing the MM function the boiler will work at the soft light fan speed. Using the CH encoder will be possible (like with a car accelerator) to make the boiler work to another fan speed. This can be useful when interested in checking the gas valve linearity. ANY ACTION CARRIED OUT IN THIS PHASE WILL HAVE NO EFFECT ON THE SOFT LIGHT FAN SPEED. Attention: our note pour function HH.

105 TECHNICAL SERVICE Parameters power in HW

106 TECHNICAL SERVICE The function is active only if the CH set-point is between 55°C e 65°C and NO EXTERNAL PROBE is connected (temperature bar flashing when entering) and PAR.42 is set to AUTO. If the R.T. is closed (request from ambient) after 20 minutes the CH set-point is increased of 5°C and a new timer starts. After another 20 minutes, if the R.T. is still closed, there is a further and final increase of 5°C. When the R.T. opens, the cycle is finished and we go back to the original set- point. The flow temperature is limited by PAR.21 (MAXIMUM CH SET-POINT ). S.A.R.A.

107 TECHNICAL SERVICE : BOOSTER FUNCTION: The function is enabled with any CH set-point, EVEN IF AN EXTERNAL PROBE IS CONNECTED, if the PAR.43 is set to AUTO. If the R.T. stays closed (ambient request) after 10 minutes from the first set- point reaching the set-point temperature is increased of 5°C. at the reaching of this new set point, if the R.T. stays closed, after another 10 minutes the set-point is increased of further 5°C. this cycle is repeated until the MAXIMUM CH SET- POINT (PAR.21) is reached. The boiler will then modulate according to this value. When the R.T. opens, the cycle is finished and we go back to the original set- point. In floor heating system is usefully set the PAR43 in OFF position Booster Tmand 60°C TEMPO T mand Campo di regolazione T mand 10 minuti 10 minuti Tmand 65°C 10 minuti Tmand 70°C Tmand 75°C Tmand 80°C 10 minuti

108 TECHNICAL SERVICE PRE-HEATING FUNCTION: If the PAR.41 is set to 1 or 2 (see seasons) when the temperature read by the DHW probe is less than 35°C and the read temperature by the CH FLOW NTC is less than 55°C, the board simulate an heat request in DHW. The burner is switched on at the minimum +15% until the read temperature of the CH FLOW NTC reaches 55°C. the burner is then stopped, the fan and the pump run for other 30. ABSOLUTE THERMOSTAT FUNCTION: In DHW mode the adjusted set-point isnt considered, but the switch off will be made if the read temperature by the DHW NTC reaches 65°C, and will be re-lighted if that temperature drops down to 63°C. DHW special functions

109 TECHNICAL SERVICE Is possible to modify the functions enabled in each season following the procedure in the section GENERIC PARAMETERS and paying attention to these rules: OFF = the function will be disabled IN ALL the seasons AUTO = the function is enabled ONLY in those seasons foreseen by the factory, as DEFAULT ON = the function is enabled in ALL the seasons Parameters

110 TECHNICAL SERVICE Each time that an heat request is made, the fan speed is checked. If it is less than REST FAN STATUS (300 rpm) the fan is supplied at PRE_PURGE SPEED (3760 rpm) for 2 seconds. The fan then runs at IGNITION SPEED (3700 rpm) for 1,2 sec. At the end of this time the gas valve operators are supplied and the spark is enabled, while the spark is produced after 1 sec. The flame is detected. To be valid, the flame signal must be present for at least 0,25 sec. The board wait for the STABILISATION_TIME (2 sec) since when the flame was sensed and declared valid. The fan is now free to modulate according to the current heat request. If no flame is sensed, the fan is held to the IGNITION SPEED, the supply is taken off from the gas valve. Only after a RE_IGNITION WAITING TIME (10 sec) a new try is allowed. The maximum number of tries is 5. Ignition procedure

112 TECHNICAL SERVICE If the PAR.10 is set to a value different from 0, the flow switch closed means a DHW heat request. During the normal DHW functioning (see seasons) the boiler shuts off if the temperature read by the DHW NTC is >= DHW set-point +5°C (or the flow NTC reaches 90°C) and re-ignites when the DHW NTC read temperature drops down to DHW set-point +4°C (or the return NTC drops to 80°C). If the DHW NTC is broken the boiler modulates on the FLOW CH NTC to a fix value equal to 55°C. The shut off is at 60°C, the re-ignition at 55°C, always on the FLOW CH NTC. The correspondent alarm code is shown only if the boiler is in stand-by (no heat request). DHW

113 TECHNICAL SERVICE During the CH functioning (and DHW) the contact of TLBT is constantly checked. If PAR.20 is set to a value different from 0, during the normal CH functioning (see seasons) the boiler shuts off when the read temperature by the FLOW CH NTC is >= to the CH set-point +5°C and re-ignites when the read temperature by the probe drops to the CH set-point -5°C. The set-point can be indifferently the one set by the end user or the one calculated by the PCB (Thermoregulation). If a problem occurs to that probe or to the CH RETURN NTC the boiler shuts off (see alarms). If the switch off of the burner is due to a reached temperature (Set- point+5°C) reason OR EVEN TO A R.T. INTERVENTION, if the PAR. 30 (CH timer selection) is set to 1 the following ignition is done after a delay time (in minutes) equal to PAR. 29. After this forced switch off, the boiler begins to work at 75% of the maximum fan speed for a time in minutes equal to PAR. 28. CH

114 TECHNICAL SERVICE Alarms Management. In this new generation of boards its possible to have more detailed alarm signals compared to the past (Icxx, CPxx, MCxx). This is made to give to the service the chance to know with an higher level of precision where the problem is, and avoid in this way loss of time and/or the substitution of functioning components. Alarms

115 TECHNICAL SERVICE There are TWO different kind of alarm (temporary-final) and THREE kind of signals: ONLY WRENCH: its a temporary alarm, that the boiler attempts to solve automatically (in the meanwhile it will go on working). If the correct functioning is not reached, we can have two different situations: (A) the WRENCH disappears, appears RESET with a different code; or (B) WRENCH + RESET, different alarm code. A RESET DURING THIS PHASE WILL HAVE NO EFFECT. (A) ONLY RESET: its necessary to reset the boiler with the RESET button. The fault is due to a random situation. If the alarm is repeated in the time, is strongly suggested to call the Service (B) WRENCH + RESET: it necessary to call the Service. Alarms

126 TECHNICAL SERVICE If an external probe (12 K -25°C) is connected and if the PAR. 44 (thermoregulation) is AUTO and if the PAR. 51 (heat request) is set to 0*, then the CH set-point will automatically set between PAR. 22 (min CH set-point) and PAR. 21 (MAX CH set-point), as follows: CH S-P=(((20°C+CORTMP)-VCTEA)x(OTC CURVE/10))+(20°C+CORTMP) where: 20°C = reference room temperature CORTMP = modifiable by the user (+5/-5°C) VCTEA = external probe composed contribute OTC CURVE = PAR. 45 *heat request generated ONLY by R.T. connection CLOSED Thermo regulation

127 TECHNICAL SERVICE Acting on the CH encoder, the end user can change degree by degree the hypothesised room temperature from the original 20°C, down to 15 °C or up to 25°C, This will change the origin of the correspondent climatic curve, from (20;20) to, i.e., (15;15) or (25;25) Thermo regulation

128 TECHNICAL SERVICE The value of VCTEA is calculated as follows: VCTEA=(VCTEAprec x 255/256)+(VTE/256) Where: VCTEAprec = previous value of VCTEA VTE = real value read by the outdoor NTC. This calculation is made every X minutes, where X is the value of PAR. 3 (kind of building light-heavy). It determines the rapidity in adapting the CH flow temperature to the changing weather conditions. The lower is the PAR.3 value, the quicker will be the modification. Thermo regulation

129 TECHNICAL SERVICE The value of OTC curve (PAR. 45, min 2.5, max 40, step 2.5) determines the gradient of the climatic curve. Its formula is the following: OTC= 10 x (Tm-20)/(20-Te) Where: Tm = the CH flow temperature, as it results from the project Te = the minimum external temperature, depending on the geographic area. Thermo regulation The following behaviour is determined by the value of PAR. 20 (CH type), if whether is 1 (CH direct) or 3 (CH with second pump). The boiler diverted valve is brought in CH, and depending on PAR. 20 only the boiler or even the external pump is supplied. If we have a switch off in CH, the boiler will restart only after a number of minutes equal to PAR. 29, and will go for a time equal to PAR. 28 to a maximum power that is the 75% of the nominal one. Is always possible to delete the CH timings (PAR. 28 and 29) setting PAR. 30 to 1.

135 TECHNICAL SERVICE NO-FROST function CH The PCB will check the CH FLOW NTC. If the reading is under the value correspondent to PAR.62, the boiler will start at 2000 rpm in 120. When the CH FLOW TEMPERATURE reaches 35°C. the burner will be switched off, while the pump will run for another 60 NO-FROST function DHW The PCB will check the CH FLOW NTC that should be under 50°C. If then the reading of the DHW NTC is under the value correspondent to PAR.61, the boiler will start in CH at 2000 rpm in 120. When the CH FLOW TEMPERATURE reaches 55°C. the burner will be switched off, while the pump will run for another 60 Each time that the fan is energised for an heat request, there is ALWAYS a post- ventilation of 6 seconds. At the end of every CH heat request there is a 60 post-circulation. PLUS: if the CH mode is activated (see seasons) and the CH FLOW NTC senses more than 78°C and is stopped at 75°C. Post circulation - Post ventilation
