Device is running with “z“ factor set to 0,1

Flow temperature is increased to 65°

The FTMP value is the flow smoothened term (Cs from your formula)

FTMP = (0,2C + 1,2Ct-1 + 1Ct-2 +0,8Ct-3 + 0,6Ct-4 + 0,3Ct-5  +0,1Ct-6 ) / 4,2

Die Division-Methode ist die, die wir bisher auch verwendet haben (ambient raw * (ambient raw / estimated flow)^1,2). Mein Vorschlag unterscheidet sich in der Anpassung des Flow-Wertes. 

Hier nutze ich eine gewichtete Glättung der letzten 7 Werte und eine zusätzliche Korrektur, deren Einfluss davon abhängt, wie stark sich die Flow-Werte von Messwert zu Messwert geändert haben. 

Cc (Flow corrected) = if (Cs - z * (Cs - 0,5 * (Cst-3+Cst-4)) < B

      then ( B )

      else (Cs - z * (Cs - 0,5 * (Cst-3+Cst-4))

The ATMP value is the Ambient Estimate calculated based on your formula

ATMP = B * ( B/ Cc) ^ 1,2
