2.0Installation

2.1Beforeyoustart

TheapplicationA260isveryﬂexible.Thesearethebasicprinciples:

Heating(circuit1andcircuit2):

Typically,theﬂowtemperatureisadjustedaccordingtoyour

requirements.TheﬂowtemperaturesensorS3(circuit1)and

S4(circuit2)arethemostimportantsensors.Thedesiredﬂow

temperaturesatS3andS4arecalculatedindividuallyintheECL

controller,basedontheoutdoortemperature(S1).Thelowerthe

outdoortemperature,thehigherthedesiredﬂowtemperature.

Bymeansoftwoweekschedules,theheatingcircuitscanbe

individuallyin‘Comfort’or‘Saving’mode(twovaluesforthe

desiredroomtemperature).

InSavingmodetheheatingcanbereducedorswitchedofftotally.

ThemotorizedcontrolvalvesM1(circuit1)andM2(circuit2)are

openedgraduallywhentheﬂowtemperatureislowerthanthe

desiredﬂowtemperatureandviceversa.

ThereturntemperaturesS5(circuit1)andS6(circuit2)tothe

districtheatingsupplyshouldnotbetoohigh.Ifso,thedesired

ﬂowtemperaturecanbeadjusted(typicallytoalowervalue),thus

resultinginagradualclosingofthemotorizedcontrolvalves.

Inboiler-basedheatingsupplythereturntemperatureshouldnot

betoolow(sameadjustmentprocedureasabove).

Furthermore,thereturntemperaturelimitationcanbedependent

oftheoutdoortemperature.Typically,thelowertheoutdoor

temperature,thehighertheacceptedreturntemperature.

Ifthemeasuredroomtemperaturesdonotequalthedesiredroom

temperatures,thedesiredﬂowtemperaturescanbeadjusted.

Thecirculationpumps,P1(circuit1)andP2(circuit2),areONat

heatdemandoratfrostprotection.
