TheapplicationA333.1isveryflexible.
Thesearethebasicprinciples:
Typically,theflowtemperatureisadjustedaccordingtoyour
requirements.
TheflowtemperaturesensorS3isthemostimportantsensor.The
desiredflowtemperatureatS3iscalculatedintheECLcontroller,
basedontheoutdoortemperature(S1)andthedesiredroom
temperature.Thelowertheoutdoortemperature,thehigherthe
desiredflowtemperature.
Bymeansofaweekschedule(upto3'Comfort'periods/day),the
heatingcircuitcanbein'Comfort'or'Saving'mode(twodifferent
temperaturevaluesforthedesiredroomtemperature).
InSavingmodetheheatingcanbereducedorswitchedofftotally.
ThemotorizedcontrolvalveM1isopenedgraduallywhentheflow

viceversa.
Thereturntemperature(S5)canbelimited,forexamplenottobe

limitationcanbedependentontheoutdoortemperature.
Typically,thelowertheoutdoortemperature,thehigherthe
acceptedreturntemperature.
Inboiler-basedheatingsupplythereturntemperatureshouldnot
betoolow(sameadjustmentprocedureasabove).
AconnectedfloworenergymeterbasedonM-bussignalcan
limitthefloworenergytoasetmaximumvalue.Furthermorethe

thelowertheoutdoortemperature,thehighertheacceptedflow/

BymeansofthepressuredifferencebetweenS9andS10the
