Then, the fllwing frmula applies fr the calculatin f real Cntrl_ Setpint Temperature sent t the AC unit: AC Setp. Temp = Ambient ref. Temp - ( KNX Amb. Temp. - KNX Setp Temp. ) AC Setp. Temp: AC indr unit setpint temperature Ambient Ref. Temp: AC indr unit return temperature KNX Amb. Temp.: Ambient temperature prvided frm KNX KNX Setp. Temp: Setpint temperature prvided frm KNX As an example, cnsider the fllwing situatin: User wants: 19ºC ( KNX Setp.
