COMMISSIONING 3. ACTIVATION OF THE DISAERATION PROCEDURE AND AUTOMATIC CALIBRATION • Switch on the boiler (by pressing the ON/OFF button) and use the Mode button to select the standby mode, where no hot water or heating requests are made. The display asks to start the deaeration and calibration procedure. • Press the OK button. The display shows: 00/00/00 00:00 Start the System air purge and automatic calibration procedure Press Ok to confirm “Attention, this procedure can be performed only by qualified personnel. To proceed, press OK button for 5 seconds.” • Press OK for 5 seconds. The display shows: “System air purge The function activates the air-purge cycle of system. To start the cycle, press “OK” button (advised) otherwise “ESC”.” • Press the OK button. Airpurge active The boiler will start a deaeration cycle lasting about 7 minutes (See below). If you need to stop it press MODE. During the deaeration cycle open the manual air vent (2) on the heat exchanger and close when clear water free of air is visible. At the end, check that the system is completely deaerated and, if not, repeat the procedure. The display shows: “If air is still present inside the system, start again the air purge cycle (OK button); otherwise press the exit button (ESC button)” • Verify that the system pressure is at least 1 bar on the pressure gauge. Open the filling valve if pressure is not sufficient and close as soon as it reaches 1 - 1.5 bar Note! If pressure in the heating circuit decreases, the display shows Malfunction warning 1P4 (parameter 241 - alert pressure). If the pressure falls below the alarm value the display will show the Warning 1P4 Error 108. Open the ALERT Filling Needed filling valve and close as soon as it reaches 1 - 1.5 bar. IN THESE CASES, THE PROCEDURE Fault 108 IS INTERRUPTED. ALERT Filling Needed AFTER FILLING THE SYSTEM THE DISPLAY REQUESTS TO START AGAIN THE SYSTEM AIR PURGE AND AUTOMATIC CALIBRATION . • After the system air purge the display shows the gas set from factory. Enter the type of gas used (if necessary), press the button to select: 0 = Natural gas (factory setting) 1 = LPG 2 = G230 (IT) 3 = G130 (FR) Press OK. The display shows: “Automatic Calibration This function enables the boiler to calibrate automatically. This procedure may take a few minutes. If you want to proceed press OK.” • Press OK to enable the Automatic Calibration. The procedure may take few minutes. The display shows the steps of the procedure If the calibration is completed the display shows “Completed Calibration” and returns to the main screen: 00/00/00 00:00 42° 1,5 bar 70° Premere OK per accedere al MENU Automatic calibration The current gas type set is: • Start the boiler by selecting the heating or domestic hot water operation using the Mode button. CAUTION IF THE CALIBRATION PROCEDURE IS NOT COMPLETED THE DISPALY SHOWS “UNCOMPLETED CALIBRATION” AND AN ERROR CODE (see table B) FOR 10 Uncompleted calibration SECONDS. 01 - Flow Check Failed FOLLOWS THE REQUEST TO ACTIVATE THE PROCEDURE 00/00/00 00:00 AGAIN. Start the System air purge PRESS OK AND REPEAT and automatic calibration procedure CALIBRATION. Press Ok to confirm IF AN ERROR IS STILL REPORTED, CONTACT A QUALIFIED TECHNICIAN. 0 Natural Gas Automatic calibration active Max. Power Intermediate Power Min power 30 /

COMMISSIONING Table B 01 Error Uncompleted calibration 01 - Flow Check Failed 00/00/00 00:00 Start the System air purge and automatic calibration procedure Press Ok to confirm Description Insufficient circulation. Make sure that: - the pump works correctly - the water pressure in the system is sufficient. WARNING!! THE AUTOMATIC CALIBRATION MUST BE DONE IN CASE OF: - REPLACEMENT OF: FAN, GAS VALVE, AIR/GAS MIXER, BURNER, ELECTRODE. - REPLACEMENT OF P.C.B. - GAS CHANGEOVER - ANY MODIFICATION TO THE FOLLOWING PARAMETERS 220 - SOFT IGNITION 231 - MAX CH ADJUSTABLE 232 - MAX DHW PERCENTAGE 233 - MIN PERCENTAGE 234 - MAX CH PERCENTAGE 02 Uncompleted calibration 02 - Overheat 00/00/00 00:00 Start the System air purge and automatic calibration procedure Press Ok to confirm - Deteted a C.H. Flow temperature ≥ 88°C in Heating Mode - Deteted a C.H. Flow temperature ≥ 88°C or a C.H. Return temperature >67°C in D.H.W. Mode. (Open a hot water tap or the zone valves/thermostatic valves on the system to dissipate heat). 4. Preparing the measuring equipment Connect the calibrated measuring device to the left-hand combustion outlet by unscrewing the screw and removing the blanking cover. Uncompleted calibration 03 - Send Probe Damaged Error 03 and the detected error (ex: Error 110 - Send Probe Damaged” - see Table summarising error codes) are displayed alternately for 10 seconds. ALERT Error 110 Send Probe Damaged Call the technical service Press the RESET button for Operation Shutdown, the display again requires to start the automatic calibration. 03 00/00/00 00:00 For Safety shut-off if the problem is removed automatically, the display again requires automatic calibration. Start the System air purge and automatic calibration procedure Press Ok to confirm If the boiler still indicates a safety shut-off, switch it off. Make sure the external electric switch is in the OFF position, shut off the gas valve and contact a qualified technician. 5. Supply dinamic pressure check Loosen the screw 1 and insert the pressure gauge connection pipe into the pipe tap. Switch the boiler on at D.H.W. maximum power, enabling the “Chimney function” (press the RESET button for 10 seconds and press th button > to select D.H.W. maximum power). The supply pressure should correspond to the value established in relation to the type of gas, for which the boiler is designed see Table summarising changes. IN ATTENTION!! THE BOILER CAN NOT BE ACTIVATED IF THE PRESSURE IS NOT CORRESPONDING TO THE TABLE SUMMARISING CHANGES / 31
