Bemerkungen:
• - Die Bezeichnungen "Flow Temperature" und "Return Temperature" werden als Vorlauf- bzw. Rücklauftempertur übersetzt.
Sie werden in den Telegrammen von Wärmezählern eingesetzt. Arbeitet ein Wärmezähler in seiner Standardanwendung als Messgerät für verbrauchte Wärme so stimmen diese Begriffe.
Wird ein Wärmezähler zur Messung der hergestellten Wärme z.B. bei Solaranlagen eingesetzt, so stimmen die Bezeichnungen nicht mehr.
In diesem Fall kann man folgende übersetzungen vornehmen:
Flow Temperature - Temperatur Warmseite.
Return Temperature - Temperatur Kaltseite.
•• - Erweiterte Identifikation (Enhanced Identification Record) :
Mit diesem VIF-Code kann die sekundäre Addresse geändert werden. Zwei Fälle sind zu unterscheiden:
1) Datenfeld stellt nur die Identifikationsnummer dar:
DIF = 0Ch VIF = 79h Data=Identification No. (8 digit BCD)
2) Datenfeld stellt die gesamte Sekundäradresse dar:
DIF = 07h VIF = 79h Data= complete ID (64 bit integer)
Das Datenfeld (64 bit) ist dann wie folgt codiert ( wie im DRH bei variablen Datenstruktur ):
| LSB | 64 Bit Integer | MSB | |||||

Bemerkungen:
•Das Codieren von VIF als ASCII-String kombiniert mit ASCII-String codierten Daten (DIF=1101b) erlaubt eine Darstellung der Daten in frei definierter Form.
