2.1Beforeyoustart

TheECLapplicationkeyA368containsof6subtypes:A368.1,
A368.2,A368.3,A368.4,A368.5andA368.6.

(examplereferringtoA368.1)

Heating(circuit1):

Typically,theflowtemperatureisadjustedaccordingtoyour
requirements.Theflowtemperaturesensor(S3)isthemost
importantsensor.ThedesiredflowtemperatureatS3iscalculated
intheECLcontroller,basedontheoutdoortemperature(S1)and
thedesiredroomtemperature.Thelowertheoutdoortemperature,
thehigherthedesiredflowtemperature.

Bymeansofaweekschedule,theheatingcircuitcanbein
‘Comfort’or‘Saving’mode.Theweekschedulecanhaveupto3
‘Comfort’periods/day.Avalueforthedesiredroomtemperature
canbesetineachofthemodes.
InSavingmodetheheatingcanbereducedorswitchedofftotally.

Themotorizedcontrolvalve(M2)isopenedgraduallywhenthe
flowtemperatureislowerthanthedesiredflowtemperatureand
viceversa.

Thereturntemperature(S5)canbelimited,forexamplenottobe
toohigh.Ifso,thedesiredflowtemperatureatS3canbeadjusted
(typicallytoalowervalue),thusresultinginagradualclosingof
themotorizedcontrolvalve.Furthermore,thereturntemperature
limitationcanbedependentontheoutdoortemperature.
Typically,thelowertheoutdoortemperature,thehigherthe
acceptedreturntemperature.

Inboiler-basedheatingsupplythereturntemperatureshouldnot
betoolow(sameadjustmentprocedureasabove).
