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.
TypicalA377.1application,examplea:
Theshowndiagramisafundamentalandsimplifiedexampleanddoes notcontainallcomponentsthatarenecessaryinasystem.
AllnamedcomponentsareconnectedtotheECLComfortcontroller.
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.

WhenthemeasuredDHWtemperatureS6getslowerthanthe charging-starttemperature,theDHWheatingpumpP1isswitched ON.
Themotorizedcontrolvalve(M1)iscontrolledinordertomaintain theheating/chargingtemperatureatS9.
TheDHWchargingpumpisswitchedONwhentheS9temperature isacceptable,whichmeansitmustbewithin3Kfromdesired heating/chargingtemperature.SeealsoapplicationA377.1,ex.d.
IfS9isplacedontheheat-exchanger'ssecondaryside,itmustbe placedintheheat-exchanger.
TheDHWchargingtemperatureisdeterminedbythedesiredDHW temperatureatS6plusthesetchargingdifference.Thecharging temperatureistypically5–10degreeshigherthanthedesired DHWtemperature.
