2.0Installation

2.1Beforeyoustart

TheapplicationA267isveryflexible.Thesearethebasicprinciples:
Heating(circuit1):
Typically,theflowtemperatureisadjustedaccordingtoyour requirements.TheflowtemperaturesensorS3isthemost importantsensor.ThedesiredflowtemperatureatS3iscalculated intheECLcontroller,basedontheoutdoortemperature(S1).
Thelowertheoutdoortemperature,thehigherthedesiredflow temperature.Bymeansofaweekschedule(upto3‘Comfort’ periods/day),theheatingcircuit1canbein‘Comfort’or ‘Saving’mode(twodifferenttemperaturevaluesfordesiredroom temperature).
ThemotorizedcontrolvalveM1isopenedgraduallywhenthe flowtemperatureislowerthanthedesiredflowtemperatureand viceversa.
Thereturntemperature(S5)tothedistrictheatingsupplyshould notbetoohigh.Ifso,thedesiredflowtemperaturecanbeadjusted (typicallytoalowervalue),thusresultinginagradualclosingofthe motorizedcontrolvalve.
Furthermore,thereturntemperaturelimitationcandepend ontheoutdoortemperature.Typically,thelowertheoutdoor temperature,thehighertheacceptedreturntemperature.
Inboiler-basedheatingsupplythereturntemperatureshouldnot betoolow(sameadjustmentprocedureasabove).
Ifthemeasuredroomtemperature(S7)doesnotequalthedesired roomtemperature,thedesiredflowtemperaturecanbeadjusted.
Thecirculationpump(P1)isONatheatdemandoratfrost protection.Thecirculationpump(P1)canbeswitchedOFF whenheatingtheDHW(dependentpriority).Ifthesystemhas achangeovervalve(P2)betweentheheatingandDHWheating circuit,thecirculationpump(P1)isONwhenheatingtheDHW.
