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
