Thepressure, to which the boiler minimum powermust be adjusted, must not be lower than thatstated in the tables (Par. 3.17) depending onthe type of gas.N.B.: to adjust the gas valve, remove the plasticcap (6); after adjusting, refit the cap.• Adjustment of the boiler minimum heat outputin heating phase.N.B.: only proceed after having calibrated theminimum domestic hot water pressure.To adjust the minimum heat output during theheating phase, change parameter (5), increasingthe value the pressure increases, reducing it thepressure drops.- The pressure to which the boiler minimum heatoutput must be adjusted must not be lower thanthat stated in the tables (Parag. 3.17).3.7 PROGRAMMING THE P.C.BThe Eolo Star 24 3 E boiler is prepared for possibleprogramming of several functioning parameters. Bymodifying these parameters as described below, theboiler can be adapted according to specific needs.To access the programming phase, proceed asfollows:- press keys (1) and (2) at the same time forapproximately 15 seconds;- Using keys (3) and (4), select the parameter tobe changed indicated in the following table:List ofparametersP0P1P2P3P4P5P6P7P8DescriptionSelect solar panelsSelect gas typeselect special gas type G110Activate anti extruder functionActivate domestic hot waterpost circulationMinimum heating powerMaximum heating powerHeating ignition timerHeating ramp timer- adjust the corresponding value consulting thetable using keys (5) and (6);- confirm the set value pressing the reset key(1) for approximately 5 seconds; pressing keys(3) + and (4) - at the same time to adjust thedomestic hot water temperature, the operationis cancelled.N.B.: after a period of time, without touchingany keys, the operation cancels automatically.Select solar panels By selecting this function, theboiler is set to be used with solar panels. Settingparameter P0 at on “solar”, the switching off ofthe burner is connected to the adjustment of thedomestic hot water temperature. In OFF mode,the burner is switched off at maximum value.N.B.: together with a solar valve kit, set theparameter P0 at on “solar” mode (correlated).Select solar panelsRange of values which canbe seton "solar" - oF (Standardsettings)ParameterP0Select gas type The setting of this function is usedto adjust the boiler in order to function with LPGgas or Methane gas.Select gas typeRange of values which canbe setLG (GPL) o nG (Metano)(Standard settings)ParameterP1Town Gas G110 – Industrial gas. The settingof this function is used to adjust the boiler inorder to function with gases from the first family.Town Gas G110 - Industrial gas (first familygas)Range of values which canParameterbe seton - oF (Standard setting)P220 - IE
Anti-Extruder function. This function reducesthe heating temperature to 57°C in the case thatdomestic hot water circulation is detected in theheating mode.Activate anti-extruder functionRange of values which canbe seton (Standard setting) - oFParameterP3Domestic hot water post circulation functionWith the post circulation function active afterdomestic hot water flow, the pump remains onfor 2.5 seconds in winter time and 1.5 secondsin summer time to reduce the formation oflime scale.Activate domestic hot water post circulationRange of values which canParameterbe seton (Settaggio di serie) - oFP4Heating power. The Eolo Star 24 3 E boiler is fittedwith an electronic modulation which adaptsthe power of the boiler to effective heat requestsof the home. Then the boiler works normally in avariable gas pressure field between the minimumheating power and the maximum heating powerdepending on the system’s heating load.N.B.: The Eolo Star 24 3 E boiler is produced andcalibrated in the heating phase to the nominalheat output. Approximately 10 minutes are neededto reach the nominal heat output changeableusing parameter (P6).N.B.: the selection of the “Minimum heatingpower” and “Maximum heating power” parameters,in the presence of a heating request, allowsswitch-on of the boiler and power supply of themodulator with current equal to the value of therespective set value.Minimum heating powerRange of values which canbe setfrom 0 % Imax. to 63 % Imax.Maximum heating powerRange of values which canbe setfrom 0 % Imax. to 99 % Imax.(Standard setting)ParameterP5ParameterP6Timer setting. The boiler has an electronictiming device that prevents the burner fromigniting too often in the heating phase. The boileris supplied as per standard with a timer adjustedat 3 minutes.Heating ramp timing. The boiler performs anignition ramp of about 10 minutes to arrive fromminimum power to nominal heating power.Heating ramp timingRange of values which canbe setfrom 1 to 101 = 30 seconds2 = 2 minutes10 = 10 minutes (Standardsetting)ParameterP83.8 AUTOMATIC SLOW IGNITIONFUNCTION WITH TIMED RAMPDELIVERY.In the ignition phase the P.C.B. carries out anincreasing gas delivery ramp (with pressure valuesthat depend on the type of gas selected) withpreset duration. This prevents every calibrationor precision adjustment of the boiler ignitionphase in any conditions of use.3.9 “CHIMNEY SWEEP FUNCTION”.When activated, this function forces the boilerat max. output for 15 minutes.In this state all adjustments are excluded andonly the temperature safety thermostat and thelimit thermostat remain active. To activate thechimney sweep function, press the Reset key forat least 10 seconds with the boiler on stand-by. Itsactivation is indicated by the flashing symbols (8and 11 Fig. 2-1). This function allows the technicianto check the combustion parameters. Afterthe checks, deactivate the function switching theboiler off and then on again.3.10 HEATING TIMER.The Eolo Star 24 3 E boiler has an electronictiming device that prevents the burner fromigniting too often in the heating phase. The boileris supplied as per standard with a timer adjustedat 3 minutes. To adjust the timer values, followinstructions for parameter settings by selectingparameter (P7) and set it with one of the valuesindicated on the relative table.3.11 PUMP ANTI-BLOCK FUNCTION.In summer function mode ( ) the boiler has afunction that starts the pump at least once every24 hours for the duration of 30 seconds in orderto reduce the risk of the pump becoming blockeddue to prolonged inactivity.In winter function mode ( ) the boiler has afunction that makes the pump start at least onceevery 3 hours for 30 seconds.3.12 FUNZIONE ANTITRAFILACIRCUITO SANITARIO.This function reduces the heating temperatureto 57°C if the domestic hot water circulation isdetected in the heating mode. The function canbe excluded using parameter (P3).3.14 P.C.B. PERIODICAL SELF-CHECK.During functioning in heating mode or withboiler in standby, the function activates every 18hours after the last boiler check/power supply. Incase of functioning in domestic hot water modethe self-check starts within 10 minutes after theend of the withdrawing in progress, for durationof approx. 10 seconds.N.B.: during self-check, the boiler remains off,including signalling.INSTALLATORUSERTECHNICIANHeating ignitions timerRange of values which canbe setfrom 1 to 101 = 30 seconds2 = 2 minutes3 = 3 minutes (Standardsetting)ParameterP73.13 RADIATORS ANTI-FREEZEFUNCTION.If the system return water is below 4°C, the boilerstarts up until reaching 42°C.21 - IE
