Thelowertheoutdoortemperature,thehigherthedesiredﬂow temperature.Bymeansofaweekschedule(upto3‘Comfort’ periods/day),theheatingcircuit1canbein‘Comfort’or ‘Saving’mode(twodifferenttemperaturevaluesfordesiredroom temperature).

ThemotorizedcontrolvalveM1isopenedgraduallywhenthe ﬂowtemperatureislowerthanthedesiredﬂowtemperatureand viceversa.

Thereturntemperature(S5)tothedistrictheatingsupplyshould notbetoohigh.Ifso,thedesiredﬂowtemperaturecanbeadjusted (typicallytoalowervalue),thusresultinginagradualclosingofthe motorizedcontrolvalve.
