16.3.2.1 Cold charging protection
InsystemAnl1.1(-1),thecold charging protection function causes a storage tank charging
tobestartedrstwhentheprimaryowtemperatureissufcientlyhighenough.
TheCO4>F22-1settingautomaticallyactivatestheinputFG2tomeasuretheprimaryow
temperature.Ifthemeasuredprimaryowtemperatureislowerthanthemeasuredstorage
tank temperature (e.g. due to a supply line that has cooled down at the start of a storage
tankcharging),theheatingcircuitvalveismovedtotheadjustedpositionatrst.Thestorage
tankchargingisnotreleasedinabsolutepriorityoperationuntiltheprimaryowtempera-
turehasrisenenoughasaresult.Paralleloperationmustbeadditionallyconguredifitisre-
quired.
