4.2 Parameterisation
When the LCD displays the code entry, you can call up the
parameterisation operation by inputting the code. You can set
date and M-Bus primary address in the parameterisation oper-
ation for example. For more detail see separate parameterisa-
tion instruction.

All segments of the display are switched on for control purpos-
es during the segment test. The flow, power and temperature
difference are recorded with the appropriate +/- signs.
The operating hours are counted from the first connection of
the power supply. The meter saves "operating time with flow"

as soon as a positive flow is recognised. Missing hours are
para operation
summated if there is a fault and the meter is thus unable to
take a measurement.
Stored maximum values are marked with an "
right hand area of the LCD.
Getting Started
Open the slide valves slowly.
Check the heating system for leak-tightness and bleed air
out carefully.
Press the button on the meter briefly.
Check the measured values for flow and temperatures for
plausibility.
Vent the heating system until the flow display is stable.
Fit the user locks to the fittings and the temperature sen-
sors. The scope of supply includes two self lock seals for
sealing a sensor and the connecting fitting.
Read the meter status for energy, volume, operation and
missing time and note the values.
Error "incorrect flow direction (negative)"
Check that the flow direction arrows on the volume measurement unit
match the flow direction of the system. If the directions do not match,
turn the volume measurement unit through 180°.
Error "negative temperature difference"
Check whether the sensors are installed correctly. If the sensors are
not installed correctly, change the installation position of the sensors.
Heating meter:
Temperature sensor in the flow-pipe with higher temperatures; temper-
ature sensor in return-pipe with lower temperature
Cooling meter:
Temperature sensor in the flow-pipe with lower temperatures; tempera-
ture sensor in return-pipe with higher temperature
