TheApplicationKeyA232contains5applications,allrelatedto
floorheatingandceilingcoolingsystems.Theapplicationsinthe

principles:
Heating/coolingwithroomtemperaturecontrol:
Typically,theflowtemperatureisadjustedaccordingtoyour

ThedesiredflowtemperatureatS3iscalculatedintheECL

roomtemperature.Thelowertheoutdoortemperature,thehigher
thedesiredflowtemperature(heating).
Oppositely,thehighertheoutdoortemperature,thelowerthe
desiredflowtemperature(cooling).Thechange-overbetween
