Pulse Generators - Honeywell QA 10 DN 25 G I Instruction Manual

Honeywell
Key date mode
-4- is displayed.
Key date and key-date volume [m³] are
displayed alternately. The standard key date
saved at the factory is 31.12.YY. The key date
volume indicates
consumption. The display will restart from "0"
if the annual consumption exceeds 999999
m³. The data can also be read out using an M-
BUS.
Reverse flow volume mode
-5- is displayed.
High resolution of the reverse flow volume in
m³.
To return to the default display: press the
button again once mode 5 has been
displayed.
