Supplied quantity of energy (tariff T7)
In tariff register 1, a quantity of energy is summated
that is calculated from the flow temperature (instead
of from the temperature difference).
Returned quantity of energy (tariff T8)
In tariff register 1, a quantity of energy is summated
that is calculated from the return temperature
(instead of from the temperature difference).
Heat/cold meter (tariff T9)
In tariff register 1, the measured quantity of cold; in
tariff register 2, the measured quantity of energy is
summated. In both cases a threshold can be defined
via the flow temperature (“cold threshold”, “heat
threshold”).
Temperature
above
“heat
threshold”
and
temperature difference > +0.2 K --> quantity of heat
is acquired
Temperature below “cold threshold” and temperature
difference < -0.2 K --> quantity of cold is acquired
Tariff control via timer switch (tariff T10)
For tariff control, one switch-off time and one switch-
on time per day can be defined. At the switch-on
time, summation of the quantity of energy or volume
is started in tariff register 1; at the switch-off time, it
is ended.
Tariff control via M-bus (tariff T11)
In tariff registers 1, 2 and 3, either the quantity of
energy or the volume can be summated. With the
relevant M-bus command, one of the 3 tariffs can be
activated or all tariffs can be deactivated.
Surcharge quantity tariff by means of return
temperature (tariff T12)
The quantity of energy is summated depending on
the return temperature in tariff registers 1 or 2.
The summated quantity of energy is calculated from
the difference of the return temperature from the
defined return temperature threshold (instead of
from the temperature difference).
Above return threshold: T1 is summated
Below return threshold: T2 is summated
Display of the tariff situation on the LCD
The current tariff status is shown in the user loop
together with the quantity of energy or the volume.
No tariff status is shown for tariffs T7 and T8.

Error messages
The meter constantly performs self-diagnostics and
can display various error messages.
Error
Error / action to be taken:
code:
F0
No flow;
air in measuring unit / pipe, vent pipe
F1
Interruption of flow sensor
F2
Interruption of return sensor
F3
Electronic for temperature evaluation defective
F4
Battery empty; replace!
F5
Short circuit flow sensor
F6
Short circuit return sensor
F7
Fault in the internal memory
F8
F1, F2, F3, F5 or F6 pending for longer than 8 hours.
No more measurements are performed.
F9
Error in the electronics
Message F8 has to be reset in parameter setting
mode (manually or service software). All other error
messages are cleared automatically once the error
has been corrected.
