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/

31)doesnotequalthedesiredroomtemperature,thedesiredflow
temperaturecanbeadjusted.

Thecirculationpump(P1)isONatheatdemandoratfrost
protection.

TheheatingcanbeswitchedOFFwhentheoutdoortemperatureis
higherthanaselectablevalue.

A247.1,A247.2:
Aconnectedfloworenergymeterbasedonpulses(S7)canlimit
thefloworenergytoasetmaximumvalue.Furthermore,the
limitationcanbeinrelationtotheoutdoortemperature.
Typically,thelowertheoutdoortemperature,thehigherthe
acceptedflow/power.

WhenthesubtypesA347.1-A347.3areused(onlyinECLComfort
