12 >>> Technical Specification... Air/gas servo : Fan Venturi Burner Control unit Gas mechanism Modulating gas valve The heart of the automatic control is made up of: - a modulating valve controlled by a diaphragm - A governor - a venturi crossed by some of the air from combustion which initiates the gas flow. The air needed for combustion crosses the venturi, at the fan entrance. The partial vacuum created at the neck of the venturi is then transmitted to the gas valve. The gas valve regulator controls the flow of gas according to the airflow: when the fan speed decreases, the regulator reduces the gas flow rate by acting on the modulating valve. On the other hand when the speed of the fan increases, the regulator increases the gas flow rate

13 >>> Technical Specification... The gas valve : Safety valves (a) Gas high flow reducer (screw acting as diaphragm) Modulating gas valve operated by air flow: Gas inlet Modulating gas valve Mechanism in closed position: The gas safety valves (a) are closed. Gas does not flow. The pressure P0 of the gas under the modulating valve membrane and under the regulator membrane is identical. Gas valve at high flow rate: Safety valves (a) Channel For settings, refer to the Maintenance chapter. Gas inlet Channel 2 Channel 3 The 2 safety valves (a) are supplied at 24 V DC: they are thus open. The gas pressure arrives at the regulator valve via channel, and continues to the membrane of the modulating valve via channel 2. The fan operating at its maximum speed causes a reduction in pressure which is transmitted under the regulator membrane via channel 3. The regulator valve then closes and all the gas pressure is concentrated under the modulating valve membrane which now opens to its maximum. Gas valve in the modulation phase: Gas inlet Safety valves (a) Channel Channel 2 Channel 3 The fan speed decreases. The pressure under the regulator membrane tends to increase. The regulator valve gradually opens. An escape flow is established via channel 3 to the fan. This escape flow causes the pressure P2 to fall under the modulating valve membrane. The modulating valve closes to a greater or lesser extent depending on the size of the escape flow in channel

16 >>> Technical Specification... The heat exchanger: Is made up of flattened stainless steel tubes in a spiral. The heat transfer is carried out in two stages: - the first stage (A) uses 5 elements depending on the model (each element has 4 turns), in direct contact with the flame. - the second stage (B) (the cold stage) uses an element placed behind a deflector (C). This is heated by the flue products just before they are evacuated. This is where the condensing occurs.

17 >>> Technical Specification... Regulation: general functions The burner can be lit following two different procedures depending on the prior condition of the unit: If the boiler has been switched off: On lighting after the electricity has been cut off (using the ON/OFF button or by disconnecting the cable), the boiler tests the circulation of water in the circuit. The procedure is as follows: - first a pre-flush of the pump depending on temperature - burner lights P = 90% of P. max and 3 seconds of stabilisation. - the outgoing temperature must rise by at least 5K. If not: - the burner then goes to max. power for 5 seconds. As soon as the 5K temperature rise is detected, the burner goes into normal operation. Otherwise the boiler cuts out indicating a fault (flashing display). Note: This is the same display as for lack of water pressure. DT < 5 C => P = 00% of P. max. for 5 seconds max. Pump pre-run Burner lights P = 90% of P. max 3 seconds DT 5 C => OK Normal operation DT 5 C => OK Normal operation This function is very useful to avoid overheating when the installation has not been fully bled (particularly at commissioning). DT < 5 C => Flashing display and made safe. If the boiler is already switched on: The principle is the same as case A, except the burner starts at about 60% of maximum power and looks for an increase of 2K instead of 5K. After the ignition phase, the regulator controls the burner in heating (reduction to Pmin) or hot water (the power is adjusted according to the need). Temperature regulation: After ignition, the burner then goes into reduced power for to 5 minutes: - minute if heating requirements are high - 5 minutes if the heating requirements are lower. After this period the power is released to be used as required. The reason for this forcing to minimum power is to favour condensation. The burner turns off at the setting +2K. (ot/min) VV TUV Note: it is recommended to use a modulating thermostat rather than a timeproportional one with this type of regulation to avoid interference

18 >>> Technical Specification... Regulation: Domestic hot water control: Regulation of tank heating (system boilers): There are 2 types of regulation allowed for a tank: either regulation by thermostat (ON/OFF contact) or regulation by NTC thermistor. In either case, the starting of the burner for a tank heating requests is preceded by a 30s pre-flush of the heating pump. This avoids the boiler being locked out in the case of too large a temperature difference between the tank and boiler temperatures. Tank equipped with a thermostat: - The closing of the thermostat conta, - the temperature of the primary circuit feeding the tank exchanger is 75 C (burner cut-off at 80 C). - the opening of the thermostat contact stops the burner and triggers a 30s pump post-flush. Tank equipped with an NTC thermistor: (NTC value: see table in accessories chapter) The tank temperature is set directly in the user menu, on the control panel (which is identical to the mixed version control panel). The thermistor allows continuous control of the tank temperature and consequent regulation of the primary circuit temperature. Tank heating start-up: when the tank temperature drops below the set temperature less 5K, the 3-way valve goes to the hot water position and the heating pump starts up. Heating stops when the NTC measures the setpoint in the tank. The pump carries out a 30s post-flush (3-way valve still in hot water position) and then stops. The regulation, in the case of a tank equipped with an NTC, is assisted by self-modification: the sensor measures the temperature 5 minutes after the burner shuts down. If the set point has been exceeded, a correction is applied to the next heating (the burner stops at a lower temperature to prevent a repetition of this temperature excess). The primary temperature depends on the setting to facilitate condensation: it is calculated at 5K below the hot water setting. In the case of scale in the tank, the primary temperature is pushed to the maximum. Regulation during hot water draw (mixed boiler): - demand detection: The burner is triggered in by a draw of.5l/min. It stops at. l/min. This hysteresis avoids having the burner in an unstable region (repetitive starts/stops). - temperature regulation: The primary regulation is performed by a calculation of the temperature setting on the primary circuit return. This calculation depends on the draw rate and the hot water temperature setting. The hot water setting is controlled by the temperature sensor in the primary return circuit (NTC5) in order to limit the influence of the cold water temperature on the hot water temperature. The presence of a solar tank is automatically detected by the solar thermistor being connected to the main circuit board (in position X32). There is no adjustment needed: the card records, at each draw, the time that it takes for the solar hot water to arrive at the boiler cold water inlet. It then applies this time to the following draw with an upper limit of 30 seconds. For example: at the first draw, the burner starts immediately but the hot water takes 0s to arrive at the boiler. On the next draw, the boiler will wait 0s before starting and record the new time the solar hot water takes. Thus the burner start-up time delay is constantly corrected for temperature variations in the solar tank

19 >>> Technical Specification... Regulation: Frost protection: The frost protection function is activated when the temperature falls below 2 C at the start of the heating circuit. The pump then runs for 0 minutes with the 3-way valve in the mixed position (central valve position to feed both the heating circuit and the plate heat exchanger): - If the temperature of the heating circuit falls below 7 C, the burner lights and remains alight until the temperature at the start of the heating circuit reaches 35 C. - If the temperature remains between 7 and 5 C, the burner lights after 30 minutes to raise the temperature to 35 C. - If the temperature exceeds 5 C, the pump runs for 30 minutes and then stops. T < 2 C 3-way in mixed position + pump ON for 0 mins T = 7 C 7 C < T < 5 C T > 5 C Burner ON T = 35 C Pump 30 minutes post-flush pump for 30 min then burner on up to 35 C pump OFF, 3-way in initial position Pump 30 minutes Protection against overheating and temperature limiting: The outlet / return thermistors protect the boiler against overheating by checking the maximum outlet temperature (97 C with the burner lit or 0 º C for 3 s with burner off). Complimentary conditions related to the flow rate in the installation: - check on the speed of temperature rise (0K/s max.) - checking the temperature difference outlet return: - if ΔT (outlet-return) > 30K => the burner is forced to minimum power for 0 minutes - if ΔT (outlet-return) > 35K => display of fault F23 initially volatile. If the fault repeats 5 times, the boiler shuts down and a reset becomes necessary. (Note: if the burner runs for at least 60 seconds, the counter is reset to zero) - 9 -

20 >>> Technical Specification... Access to installer and After-Sales menus : The display has hidden menus accessible by entering a code. This code is of interest to two groups of professionals: - The installer who needs to configure the appliance during installation => code 96 - The after-sales service who may need to change parts and then reconfigure them for the appliance => code 35 The installer menu gives access to a restricted list of data items whereas the After-Sales menu gives access to all the data items (installation + after-sales).

24 >>> Technical Specification... Installer Menu: The external sensor operation Setting is done using 2 parameters: - The sensor slope to be chosen on the curve below (): To know which slope to select, you need to know the local minimum temperature which was used for installation calculations. Choose the slope that gives the maximum heating setting at the local minimum temperature. See example below. Temperature setting Heating temperature ( C) With an e-bus thermostat (Exacontrol E...) the slope is set on the thermostat. This setting no longer appears in the boiler menu Outside temperature ( C) - Heating curve base correction (2): This parameter is used to correct the ambient temperature if the real temperature is different from the expected temperature. The factory setting (20 ) corresponds to an estimated ambient temperature. This value can be increased (up to 25 C) or reduced (down to 5 C). E.g.: desired temperature = 20 C, real temperature = 9 C => set to 2 C to offset the curve. Note: if the outside sensor is associated with a modulating thermostat, the curve base adjusts itself automatically With an e-bus thermostat (Exacontrol E...) the curve base adapts itself as needed. This setting no longer appears in the boiler menu Example: Either an installation equipped with radiators calculated according to the European standard NF EN 442 (Delta T between air and water = 50 degrees): the maximum heating temperature will then be 73 C (factory setting). Or a minimum local temperature of -6 C. In tracing on the diagram below the vertical from Text -6 C, then the horizontal to 73 C, we arrive at a slope of

This function enables controls of the burner ignition. The appliance operates at adjusted maximum heating power. The 3-way valve is in the central position and the pump and the burner turn off for refilling the appliance. This function is activated for 5 minutes. --> The 3-way valve goes to the heating position. --> The pump operates in cycles of 5 seconds on / 5 seconds off. Ensure that the bleed valve is open. This function is activated for 5 minutes (4 minutes in DHW, minute in heating). --> The pump operates in cycles of 5 seconds on / 5 seconds off. Ensure that the bleed valve is open. This feature can be activated automatically when filling: if the pressure measured by the sensor passes from 0 to 0.5 b, the panel interprets this as a filling and activates the air venting device to prevent ignition of the burner when the exchanger is filled with air. In such a case, the pressure indication on the display will flash. However, if the transition from 0 to 0.5 bar is too fast (less than 5 seconds), the panel interprets this as a parasite and does not launch the function

43 >>> Installation... Installation recommendations: Anti-corrosion and anti-sludge protection: To avoid any corrosion, it is recommended that you add a corrosion inhibitor to the heating circuit water. This inhibitor will prevent any electrical reactions between the different metals in the installation. As a consequence, it also prevents the formation of gasses that may be produced by chemical reactions. Water treatment is particularly important for plate heaters as the low temperature is favourable to bacterial growth. This can result in sludge that can block all or part of the circuit. For the dosage of these products, you must know the volume of water in the circuit. It is recommended that you make a note of this volume for future use. The inhibitors must be compatible with the materials used in the circuit. Bleeding the heating circuit: The boiler is equipped with an automatic bleed valve in the heating circuit. However, it may be useful to provide one or more additional bleed valves in the installation, particularly at the high points. This will make it possible to bleed the system more quickly. 2 Pump bleed valve plug 2 Pump 3 Pump shaft screw

44 >>> Installation... Check-list for commissioning a heater: Step Action Check - Before switching on. Check the electrical connections. 2 - Before pressurising 3 - Switch the appliance on, with no demand. 4 - Place the heating circuit under pressure. Check the expansion tank pre-inflation pressure. Deactivate heating and hot water using the control panel buttons. Un-stick the pump Open the taps on the fixing jig. Check that all heating circuit taps are open. Raise the pressure to 2 bar. (general power, connection of accessories, thermostat...) The tank may loose pressure, particularly if it has been stored for a long time. Water leaks. The air venting system must be activated (P07). The appliance is not available for 5 min. Warning: If the pressurisation lasts for less than 5 seconds (for example, by opening the connection plate valves when the installation is already pressurised), the automatic air venting function is not operable. Then it is advisable to start this sequence manually by means of the function P.07 (see section «test mode» in «Technical specification» chapter) before air venting the installation (next step). 5 - Bleed the air from the heating circuit. Reset the pressure after bleeding. Start test function P.06 (see test mode in Technical specification chapter). Open the heating and installation bleed valves. 6 - Bleed the domestic hot water circuit. Open the hot water taps on the installation to remove the air. 7 - Turn on the gas. Open the gas tap on the fixing jig. 8 - Boiler configuration at installation. 9 - Run the appliance in heating mode 0 - Run the appliance in domestic hot water mode - Explain the appliance to the end-user. Adjust the various parameters on the installation menu depending on the installation and the accessories. Set the heating flow rate through the bypass if necessary. Explain the main operations : ON/ OFF, RESET, filling the system, DHW and heating temperature adjustment, Take care that the end-user has his booklet. Carefully check for leaks with an electronic detector or soapy water. Check the value displayed on the After-Sales menu item d44 (ionisation quality). If this value drifts over time, it indicates a deterioration in flame detection. Check that the water circulates correctly and that the appliance shuts off correctly when reaching the temperature set. Check the exhaust circuit for leaks. Check that the heating flow rate is adequate. Check the hot water temperature. Ensure that it meets the user s requirements

45 >>> Maintenance... Service visit : List of recommended annual checks: Components Check Method Domestic hot water flow rate sensor Gas valve NTC Thermistors Flame detection (ionisation): Temperature regulation Pressure sensor Expansion tank Ignition of the burner for a domestic hot water flow rate of.5l/min Does the gas flow rate modulate correctly? Measure the resistance of each thermistor (2,500Ω at 20 C,,750Ω at 70 C) Ionisation quality Does the burner shut off at the end of regulation? Does the sensor stop the boiler if the pressure drops below 0.3 bar? Does the tank still contain gas? In the installer menu, line d36 indicates the domestic hot water flow rate. - Check that the burner properly ignites at the expected flow rate. - Check that the flow rate measured corresponds to reality. Draw off water at max. flow rate Reduce the draw rate until the burner goes off. Check that the gas flow rate follows. Disconnect the thermistors to measure the resistance. The ionisation quality can be checked with data item d44 of the After-Sales menu: Less than 300 with the burner lit = good detection Check that the burner shuts off when it approaches the setting (test to be performed in hot water mode at low flow rate) If possible, close the heating circuit isolation valves and drain the boiler until it shuts off. Check that the water pressure remains stable in operation. If not, check the tank pressure when empty. Also check: - combustion: measure the level of CO2 in the exhaust. Adjust the gas valve if necessary. - Check that there are no water leaks (at connections, safety valves, disconnect... ) - Check that there are no gas leaks (at connections, gas valve...) - the sealing of the exhaust ducts - the electrical ground connections Clean: - the burner: the burner gasket must be replaced each time it is removed - the main heat exchanger - the fan - the condensate tank () [remove (2), clean, rinse with water] - the heating filter (if necessary, clean the installation) - domestic hot water filter 2 The seals must be replaced each time they are removed

46 >>> Maintenance... Service visit: Additional operations during five-yearly visits. Components to clean: - heating valve (remove and rinse in water to remove any deposits) - Descale the plate heat exchanger The seals must be replaced each time they are removed. Check the fault history during the maintenance visit: It is important to check the fault history (see below) during the maintenance visit to see if any repetitive faults are occurring. Some faults do not display on the screen but are recorded in the log: - fault F22: lack of water pressure (the symbol appears, however, on the screen) - fault F49: voltage too low on the e-bus or short circuit on the e-bus connector Ionisation quality check: Check value d44 on the after-sales menu. If this value drifts from one maintenance to another, it indicates a deterioration in flame detection. (Note: This value is in a range of 0 to 000. The lower the value when the burner is lit, the better the detection. However, the value varies from one installation to another. Therefore, it is not possible to give a standard value.
