2.0Installation

2.1Beforeyoustart

Theapplications(subtypes)intheA377applicationkeyarevery

ﬂexibleandalmostidentical.

However,someapplicationshaveextrafunctionswhichare

describedseparately.

Thesearethebasicprinciples:

Heating(circuit1):

Typically,theﬂowtemperatureisadjustedaccordingtoyour

requirements.TheﬂowtemperaturesensorS3isthemost

importantsensor.ThedesiredﬂowtemperatureatS3iscalculated

intheECLcontroller,basedontheoutdoortemperature(S1).

Thelowertheoutdoortemperature,thehigherthedesiredﬂow

temperature.

Bymeansofaweekschedule(upto3‘Comfort’periods/day),the

heatingcircuitcanbein‘Comfort’or‘Saving’mode(twodifferent

temperaturevaluesforthedesiredroomtemperature).

InSavingmodetheheatingcanbereducedorswitchedofftotally.

ThemotorizedcontrolvalveM2isopenedgraduallywhenthe

ﬂowtemperatureislowerthanthedesiredﬂowtemperatureand

viceversa.

Thereturntemperature(S5)tothedistrictheatingsupplyshould

notbetoohigh.Ifso,thedesiredﬂowtemperaturecanbeadjusted

(typicallytoalowervalue),thusresultinginagradualclosingof

themotorizedcontrolvalve.Furthermore,thereturntemperature

limitationcanbedependentontheoutdoortemperature.

Typically,thelowertheoutdoortemperature,thehigherthe

acceptedreturntemperature.

Inboiler-basedheatingsupplythereturntemperatureshouldnot

betoolow(sameadjustmentprocedureasabove).

Ifthemeasuredroomtemperature(RemotecontrolunitECA30/

31)doesnotequalthedesiredroomtemperature,thedesiredﬂow

temperaturecanbeadjusted.

Thecirculationpump(P2)isONatheatdemandoratfrost

protection.

TheheatingcanbeswitchedOFFwhentheoutdoortemperatureis

higherthanaselectablevalue.

AconnectedﬂoworenergymeterbasedonM-bussignalcanlimit

theﬂoworenergytoasetmaximumvalue.Furthermore,the

limitationcanbeinrelationtotheoutdoortemperature.

Typically,thelowertheoutdoortemperature,thehigherthe

acceptedﬂow/power.

Thedesiredﬂowtemperatureofheatingcircuit1can,viaS7,be

controlledbymeansofanexternalvoltageintherange0-10volt.

Thefrostprotectionmodemaintainsaselectableﬂowtemperature,

forexample10°C.

Analarmcanbeactivatediftheactualﬂowtemperaturediffers

fromthedesiredﬂowtemperature.

TheroomtemperaturesignalcanbeachievedfromtheRemote

ControlUnitECA30/31,ifconnected.

A377.2:

WhenbothDHWheating/chargingandheatingcircuit1are

active,thecirculationpumpintheheatingcircuitcancontinue

operating.Theheatingcircuittemperatureistypicallyincreased.

Thisisparallelmode.Iftheincreaseoftheﬂowtemperature

cannotbeaccepted,thecirculationpumpinheatingcircuitcanbe

stopped.ThisisDHWprioritymode.
