Theapplications(subtypes)intheA376applicationkeyarealmost

identical.However,someapplicationshaveextrafunctionswhich

aredescribedseparately.

Heating(circuit1):

Typically,theﬂowtemperatureisadjustedaccordingtoyour

requirements.Theﬂowtemperaturesensor(S3)isthemost

importantsensor.ThedesiredﬂowtemperatureatS3iscalculated

intheECLcontroller,basedontheoutdoortemperature(S1)and

thedesiredroomtemperature.Thelowertheoutdoortemperature,

thehigherthedesiredﬂowtemperature.Bymeansofaweek

schedule,theheatingcircuitcanbein‘Comfort’or‘Saving’mode

(twovaluesforthedesiredroomtemperature).InSavingmodethe
