COMMISSIONING AUTO

COMMISSIONING AUTO function This is a function which enables the boiler to automatically adapt its operation routine (the temperature of the heating elements) in line with the outdoor conditions, in order to achieve and maintain the requested room temperature conditions. Depending on the peripheral units connected and the number of zones controlled, the boiler adjusts its flow temperature automatically. The various corresponding parameters should therefore be set (see adjustments menu). To activate the function, press the Auto button. 27/10/21 10:22 0° 40° 1,5 bar 70° AUTO C Heating active Example 1: Single zone system (high-temperature) with on/off room Thermostat: In this case the following parameters must be set: 4 21 - Activation of temperature adjustment using sensors - Select 1 = Basic temperature adjustment 2 44 - Boost Time (optional) The wait time for the flow temperature increase in steps of 4°C may be set. The value varies according to the type of system and installation. If the Boost Time value = 00 the function is not activated. Example 2: Single zone system (high-temperature) with on/off room Thermostat + outdoor sensor: In this case the following parameters must be set: 4 21 - Activation of temperature adjustment using sensors - Select 3 = outdoor sensor only 4 22 - Temperature adjustment curve selection - Select the relevant curve according to the type of system, installation, heat insulation used in the building, etc. 4 23 - Perform a parallel curve shift if necessary, increasing or decreasing the set-point temperature (this may also be modified by the user, using the heating temperature adjustment knob, which, with the Auto function activated, is used to shift the curve in a parallel manner). Example 3: Single zone system (high-temperature) with Sensys HD controller + outdoor sensor In this case the following parameters must be set: 4 21 - Activation of temperature adjustment using sensors - select 4 = outdoor sensor + room sensor 4 22 - Temperature adjustment curve selection - Select the relevant curve according to the type of system, installation, heat insulation used in the building, etc 4 23 - Perform a parallel curve shift if necessary, increasing or decreasing the set-point temperature. (This may also be changed by the user by the buttons 8 which, with the Auto function activated, is used to shift the curve in a parallel manner.) 4 24 - Influence of room sensor - used to adjust the influence the room temperature has on the calculation of the set-point flow temperature (20 = maximum, 0 = minimum). Note: See page 38 for details on accessing menus. / 38 420011270900 - Rev. 04 - 072024

ALERT BOILER PROTECTION DEVICES Appliance shut-off conditions The boiler is protected from malfunctions by means of internal checks performed by the electronic P.C.B., which stops the boiler from operating if necessary. In the event of the boiler being shut off in this manner, a code appears on the control panel display which refers to the type of shut-off and the reason behind it. Two types of shut-off may occur: Safety shut-off This type of error is “volatile”, which means that the boiler starts up again automatically as soon as the problem which caused the shut-off is removed. The display shows the code and the error description. “Fault 110 - Send Probe Damaged” Operation shutdown This type of error is “non-volatile”, which means that it is not removed automatically. The display shows the code and the error description. To restore normal operation press the RESET button on the control panel. The dispay shows “Reset in progress” and then “Fault solved”. If the problem manifests itself again after several attempts to reset the appliance, contact a qualified technician. ALERT Fault 501 No flame detected Press the Reset button Fault 501 No flame detected Press the Reset button ALERT Fault 110 Send Probe Damaged Reset in corso In fact, soon as the cause of the shut-off disappears, the boiler starts up again and continues to operate normally. 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. Safety shut-off due to insufficient water pressure In caso di insufficiente pressione dell’acqua nel circuito riscaldamento la caldaia segnala un arresto di sicurezza. The display shows “Fault 108 - Filling Needed”. ALERT Fault 108 Filling Needed If the re-balancing request is performed on a frequent basis, switch the boiler off, bring the external electric switch to the OFF position, shut off the gas valve and contact a qualified technician to check for any leaks of water. Fault solved Important If this shutdown occurs frequently, contact an authorised Technical Service Centre for assistance. For safety reasons, the boiler will permit a maximum of 5 resets in 15 minutes (5 presses of the RESET button); at the 6th attempt within this 15-minute period the boiler will shut down and may only be operated again after the electricity supply has been disconnected. If the shutdown is occasional or an isolated event, this is not a problem. The first figure of the error code (e.g. 1 01) indicates within which operational assembly the error occurred. 1 - Primary Circuit 2 - Domestic Hot Water Circuit 3 - Internal Electronic Part 4 - External Electronic Part 5 - Ignition and Detection 6 - Air inlet - flue gas outlet 7 - Multizone heating 8 - Combustion Control System Malfunction warning This warning is shown by the display in the following format: 5 P3 = Flame cut-off the first figure indicating the operational assembly is followed by a P (warning) and the code relating to the specific warning. Circulation pump malfunction signal The circulation pump has an LED display that shows its operating status: LED off: The circulation pump is electrically charged. LED solid green: circulation pump enabled. LED flashing green: change of speed taking place. LED red: Circulation pump is blocked or lacks water. Installation and servicing instructions / 39
