Typically,theflowtemperatureisadjustedaccordingtoyour
requirements.TheflowtemperaturesensorS3isthemost
importantsensor.ThedesiredflowtemperatureatS3iscalculated
intheECLcontroller,basedontheoutdoortemperature(S1)and
thedesiredroomtemperature.
Thelowertheoutdoortemperature,thehigherthedesiredflow
temperature.

Bymeansofaweekschedule,theheatingcircuitcanbein
‘Comfort’or‘Saving’mode.Theweekschedulecanhaveupto3
‘Comfort’periods/day.Avalueforthedesiredroomtemperature

InSavingmodetheheatingcanbereducedorswitchedofftotally.

ThemotorizedcontrolvalveM1isopenedgraduallywhenthe

viceversa.

ThereturntemperatureS5tothedistrictheatingsupplyshouldnot
betoohigh.Ifso,thedesiredflowtemperaturecanbeadjusted
(typicallytoalowervalue),thusresultinginagradualclosingofthe
motorizedcontrolvalve.

Inboiler-basedheatingsupplythereturntemperatureshouldnot
betoolow(sameadjustmentprocedureasabove).

Furthermore,thereturntemperaturelimitationcanbedependent
oftheoutdoortemperature.Typically,thelowertheoutdoor
temperature,thehighertheacceptedreturntemperature.

Ifthemeasuredroomtemperature(directlyconnectedtemperature
sensorESM-10(S2)orRemotecontrolunitECA30/31)doesnot
equalthedesiredroomtemperature,thedesiredflowtemperature
canbeadjusted.

Thecirculationpump,P1,isONatheatdemandoratfrost

TheheatingcanbeswitchedOFFwhentheoutdoortemperatureis
