2.0Installation
2.1Beforeyoustart
Theapplications(subtypes)intheA247applicationkeyarevery
flexibleandalmostidentical.However,someapplicationshave
extrafunctionswhicharedescribedseparately.
Thesearethebasicprinciples:
Heating(circuit1):
Typically,theflowtemperatureisadjustedaccordingtoyour
requirements.TheflowtemperaturesensorS3isthemost
importantsensor.ThedesiredflowtemperatureatS3iscalculated
intheECLcontroller,basedontheoutdoortemperatureS1andthe
desiredroomtemperature.Thelowertheoutdoortemperature,
thehigherthedesiredflowtemperature.
Bymeansofaweekschedule(upto3‘Comfort’periods/day),the
heatingcircuitcanbein‘Comfort’or‘Saving’mode(twodifferent
temperaturevaluesfordesiredroomtemperature).
InSavingmodetheheatingcanbereducedorswitchedofftotally.
ThemotorizedcontrolvalveM2isopenedgraduallywhenthe
flowtemperatureislowerthanthedesiredflowtemperatureand
viceversa.
Thereturntemperature(S5)tothedistrictheatingsupplyshould
notbetoohigh.Ifso,thedesiredflowtemperaturecanbeadjusted
(typicallytoalowervalue),thusresultinginagradualclosingofthe
motorizedcontrolvalve.
Inboiler-basedheatingsupplythereturntemperatureshouldnot
betoolow(sameadjustmentprocedureasabove).
Furthermore,thereturntemperaturelimitationcanbedependent
oftheoutdoortemperature.Typically,thelowertheoutdoor
temperature,thehighertheacceptedreturntemperature.
Ifthemeasuredroomtemperature(RemotecontrolunitECA30/

temperaturecanbeadjusted.
Thecirculationpump(P1)isONatheatdemandoratfrost
protection.
TheheatingcanbeswitchedOFFwhentheoutdoortemperatureis

A247.1,A247.2:
Aconnectedfloworenergymeterbasedonpulses(S7)canlimit
thefloworenergytoasetmaximumvalue.Furthermore,the
