Heating(circuit1):
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

viceversa.
Thereturntemperature(S5)tothedistrictheatingsupplyshould
notbetoohigh.Ifso,thedesiredflowtemperaturecanbeadjusted
(typicallytoalowervalue),thusresultinginagradualclosingofthe
motorizedcontrolvalve.
Furthermore,thereturntemperaturelimitationcandepend
ontheoutdoortemperature.Typically,thelowertheoutdoor
temperature,thehighertheacceptedreturntemperature.
Inboiler-basedheatingsupplythereturntemperatureshouldnot
betoolow(sameadjustmentprocedureasabove).
