Typically,theﬂowtemperatureisadjustedaccordingtoyour

requirements.TheﬂowtemperaturesensorS3isthemost

importantsensor.ThedesiredﬂowtemperatureatS3iscalculated

intheECLcontroller,basedontheoutdoortemperature(S1).

Thelowertheoutdoortemperature,thehigherthedesiredﬂow

temperature.Bymeansofaweekschedule(upto3‘Comfort’

periods/day),theheatingcircuit1canbein‘Comfort’or

‘Saving’mode(twodifferenttemperaturevaluesfordesiredroom

temperature).

ThemotorizedcontrolvalveM1isopenedgraduallywhenthe

ﬂowtemperatureislowerthanthedesiredﬂowtemperatureand

viceversa.

Thereturntemperature(S5)tothedistrictheatingsupplyshould

notbetoohigh.Ifso,thedesiredﬂowtemperaturecanbeadjusted

(typicallytoalowervalue),thusresultinginagradualclosingofthe

motorizedcontrolvalve.

Furthermore,thereturntemperaturelimitationcandepend

ontheoutdoortemperature.Typically,thelowertheoutdoor

temperature,thehighertheacceptedreturntemperature.

Inboiler-basedheatingsupplythereturntemperatureshouldnot

betoolow(sameadjustmentprocedureasabove).
