Bymeansofaweekschedule,theheatingcircuitcanbein ‘Comfort’or‘Saving’mode(twodifferenttemperaturevaluesfor desiredroomtemperature).

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.
