3.2 Monthly values
The meter stores the following values for 15 months on the
monthly set day
• Energy (meter status)
• Volume (meter status)
• Missing hours (meter status)
When the meter shows the monthly set day, press the button
for 3 s in order to display the previous month's values.
You can also read the monthly values via the optical interface.
4. Functional Details
If the respective operation thresholds are exceeded and flow
and temperature difference are positive, the meter summates
the energy and the volume. All segments of the display are
switched on for control purposes during the segment test.
The meter status for energy, volume and missing time is en-
tered into a log for the previous year on an annual basis on the
annual set day.
The flow, power and temperature difference are recorded with
the appropriate +/- signs. If the operation threshold has
dropped, a "u" is displayed in front. The current temperatures
are presented together as whole numbers in °C in a display
line.
You can set the 8 digit property number (secondary address
for M-Bus operation) in the parameterising mode. The highest
value point is suppressed in the display. The device number is
issued by the manufacturer.
The operating hours are counted from the first connection of
the power supply. Missing hours are summated if there is a
fault and the meter is thus unable to take measurements. The
date is incremented on a daily basis.
The number for the firmware version is issued by the manufac-
turer.
5. Error Messages
The meter continuously runs a self-diagnosis and can thus
recognise and display various installation or meter error mes-
sages.
The error message F0 means that no flow measurement is
possible, due to air in the volume measurement unit for exam-
ple; the system must be vented carefully.
The error message F4 means the battery must be replaced.
When any of the error messages F1, F2 or F5, F6, F8 are
displayed, the temperature sensors are defective. The mes-
sages F3, F7, F9 mean a defect in the electronics.
Contact the service department in all these cases.
