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

InSavingmodetheheatingcanbereducedorswitchedofftotally.
ThemotorizedcontrolvalveM1isopenedgraduallywhentheflow

Typically,thelowertheoutdoortemperature,thehigherthe
acceptedreturntemperature.
Inboiler-basedheatingsupplythereturntemperatureshouldnot

AconnectedfloworenergymeterbasedonM-bussignalcan
limitthefloworenergytoasetmaximumvalue.Furthermorethe

BymeansofthepressuredifferencebetweenS9andS10the
